Abstract

The occurrence of recessed marks on a surface of weather strip having a core member embedded therein is prevented. Core member (16) to be embedded in weather strip (13) is obtained by linking multiple core member piece parts (22) at given intervals so as to provide separation space parts (24) between individual core member piece parts (22), filling the interior of the separation space parts (24) with filling polymer material (P2) to a thickness substantially equal to that of the core member piece parts (22), and coating the whole surface of the core member (16) with the filling polymer material (P2). Accordingly, in the forming of weather strip (13), the thicknesses of polymer material (P1) for trim member forming at the area covering the core member piece parts (22) and at the area covering the separation space parts (24) filled with the filling polymer material (P2) are made substantially identical with each other, thereby attaining substantially zeroing of the variation of molding shrinkage along the thickness direction of the polymer material (P1) for trim member forming.

Description

Fringing material and core thereof and their manufacturing approach and manufacturing installation
Technical field
The present invention relates to the core that is embedded in the long fringing material and used by incorporate fringing material and the manufacturing approach and the manufacturing installation of this core, buries core underground and fringing material and the manufacturing approach of this fringing material and the invention of manufacturing installation of incorporate length.
Background technology
Usually, on the flange of the car door edge of opening of vehicles such as automobile, vehicle window edge of opening, along the long fringing material of this flange assembling.This fringing material is to have cross-sectional plane to be the shape of the installation portion of U word shape roughly through rubber, themoplasticity synthetic resin polymeric materials such as (comprising thermoplastic elastomer) extrusion forming; With this roughly the installation portion of U word shape clip the flange of edge of opening, thereby be fixed on the flange.This fringing material is integrated with core (for example metal sheet such as cold-rolling steel) for the reinforcement of the length of U word shape roughly through in installation portion, burying cross-sectional plane underground, can strengthen installation portion and installation portion stably is fixed on the flange of edge of opening with core.
But; The flange of car door opening edge, vehicle window edge of opening is because end wise two dimension or three-dimensional ground are crooked; Therefore be shaped to the fringing material of straight wire through extrusion forming, crooked and be assembled with the curved shape of the flange of the edge of opening ground that matches.Therefore, being embedded in core in the fringing material uses end wise is formed with spatial portion with predetermined distance part stamping-out core (being also referred to as fish-bone core, keel core sometimes) with crooked freely along with the bending of fringing material.
But; Make the fringing material that is embedded with core if cover this part stamping-out core with polymeric material with the fringing material forming; Then alongst produce indenture (being also referred to as the keel trace sometimes) with predetermined distance on the surface of fringing material, the aesthetic appearance of fringing material might variation.For the maintenance intensity that improves the fringing material thickens the thickness of slab size of core, the thickness of slab size of core is big more with the gauge of polymeric material with respect to the fringing material forming that covers core, then produces this indenture more significantly.
Think that the reason that produces this indenture is following.Owing to the narrow width of the length direction of the spatial portion that on part stamping-out core, forms, be generally about 1mm with predetermined distance; Resistance to flow when making the fringing material forming with polymeric material inflow space portion is big, is difficult to make the polymeric material of abundant amount to flow in the spatial portion.Further; Be equivalent to cover the part of the spatial portion (part that does not have core) of the core in the polymeric material that the fringing material forming of core uses; Compare with the part that has core, the gauge of polymeric material increases, so the moulding amount of contraction of the polymeric material of this part increases.Therefore, think that the part of spatial portion (part that does not have core) of the core in the surface that is equivalent to the fringing material produces indenture.
The problem that the aesthetic appearance that causes for the generation that solves this indenture reduces; Such as patent documentation 1 (japanese kokai publication hei 9-76835 communique) record; The part of the slit (spatial portion) through the core in covering the fringing material forms a plurality of prominent bar of end wise elongation; And cover these prominent bars with expanded cellular rubber, make thus in that to be embedded with the indenture that produces on the fringing material of core not remarkable.
Patent documentation 1: japanese kokai publication hei 9-76835 communique (the 2nd page etc.)
But the technology of above-mentioned patent documentation 1 is to make the inapparent technology of indenture that produces on the fringing material of core being embedded with, and can not prevent the generation of indenture itself.
Think in addition; In order to suppress the generation of indenture; Fringing material forming through will covering core thickens with the gauge of polymeric material and (typically says; The thickness more than 3 times for the gauge of core), thus in the part that is equivalent to the spatial portion of core (part that does not have core) and exist between the part of core, reduce polymeric material gauge difference and reduce the difference of the moulding amount of contraction of polymeric material.But, in the method,, therefore have the shortcoming that weight increases and cost increases of fringing material because the amount of the polymeric material that the fringing material forming of covering core is used increases.
Summary of the invention
The present invention considers above-mentioned situation and proposes.Therefore, the objective of the invention is to, can prevent to produce indenture, and can bring into play the function of the regulation of fringing material on the surface of the fringing material that is embedded with core.In addition, also can thicken the fringing material forming that covers core gauge, can satisfy the requirement of range of choice expansion of the materials used of fringing material with polymeric material.
In order to reach above-mentioned purpose; The core that fringing material of the present invention is used is formed by the core raw MAT'L of the roughly band plate-like of the certain thickness length that is shaped to thickness 0.15mm～1.0mm in advance in addition; Through alongst being dashed to form separated space portion or will enlarge along the slit end wise that the raw-material length direction of said core forms with predetermined distance with predetermined distance, the raw-material part of core forms separated space portion; The a plurality of core sheet portion that has alongst with the predetermined distance configuration is connected this a plurality of core sheet portions connecting portion each other with end wise; Through when the long fringing material of moulding; Fringing material forming with this fringing material of moulding covers with polymeric material; Thereby be embedded in this fringing material and by integrated; Through can not hinder adjacent core sheet portion near or away from degree under, in separated space portion, fill and compare with the core raw MAT'L, hardness is little, flexibility is high and can use polymeric material with the filling that the polymeric material chemical engages with the fringing material forming; And between adjacent core sheet portion, keep filling using polymeric material; Thus when moulding fringing material, be filled with the part of covering core sheet portion in the polymeric material and connecting portion and covering between the part of filling at the fringing material forming with the separated space portion of polymeric material, reduce or eliminate the difference of this fringing material forming with the moulding amount of contraction of the thickness direction of polymeric material.
That is to say; Be filled in the separated space portion of core through filling with polymeric material; Thereby can be when moulding fringing material; Be filled with the part of covering core sheet portion in the polymeric material and connecting portion and covering between the part of filling at the fringing material forming, reduce or eliminate the difference of fringing material forming with the gauge of polymeric material with the separated space portion of polymeric material.And, can reduce or eliminate the difference of fringing material forming with the moulding amount of contraction of the thickness direction of polymeric material.Therefore, can prevent to produce indenture, and can bring into play the function of the regulation of fringing material on the surface of fringing material.
And, need not the gauge of the fringing material forming that covers core with polymeric material thickened, even it is thin with the gauge of polymeric material to cover the fringing material forming of core, also can prevent to produce indenture on the surface of fringing material.Therefore, the consumption of fringing material forming be can reduce, the lightweight of fringing material and the requirement of cost degradation satisfied with polymeric material.
In addition; Though since fill can use at an easy rate in intensity, aspect of performance with polymeric material poorer than new product material (not materials used); But low-cost material (for example; Again utilize material, discarded with material etc.), what therefore can enlarge materials used effectively utilizes scope and cost-cutting.
Further, be filled in the separated space portion, therefore reduce space (small space) and remain between the core sheet portion owing to will fill with polymeric material.Thus; Can prevent along with because of the temperature traverse in the manufacturing process of fringing material (for example; When the fringing material forming is handled with the heat hardening of polymeric material, the temperature traverse when cooling curing is handled etc.), the expansion in the space that causes of the manufacturing of the fringing material temperature traverse (temperature traverse after for example, being assembled on the vehicle etc.) after accomplishing or contraction and the areal deformation of fringing material.
At this moment, can remove the part that is equivalent to separated space portion through the part and the stamping-out that stay the partial sum that becomes core sheet portion in the core raw MAT'L and become connecting portion, thereby form core sheet portion, connecting portion and separated space portion.Perhaps; The part that becomes connecting portion that also can be in staying the core raw MAT'L and will be under the state that many slit end wises that extend on the Width form with predetermined distance; End wise enlarged slit when the part that becomes this connecting portion was extended in the end wise calendering, formed core sheet portion, connecting portion and separated space portion thus.In either event, can use known manufacturing approach and manufacturing installation easily to make the core that is formed with separated space portion.

As shown in Figure 1, on the flange 12 of the car door edge of opening of sidepiece, rear portion or the roof of body panels 11, along the long sealing band 13 (fringing material) of these flange 12 assemblings.Sealing bar 13 is through the extrusion forming of fringing material formings such as themoplasticity synthetic resin (comprising thermoplastic elastomer) or rubber with polymeric material P1; Form cross-sectional plane and be the installation portion 14 of U word shape roughly and the hollow sealing portion 15 of sponge material system, in installation portion 14 through inserting the core 16 of the length of stating after moulding is embedded with.The fringing material forming of moulding sealing bar 13 uses polymeric material P1 for example to use the durometer hardness that obtains according to JIS K7215 to be HDA50～80 (being preferably HDA60～70), with EPDM (ethylene-propylene-diene rubber) be the main body can elastic deformation rubber or olefines can elastic deformation themoplasticity synthetic resin.
In addition, on the inner peripheral surface of the inner peripheral surface of the car of installation portion 14 outside sidewall 17 and car inside side walls 18, form respectively towards interior side-prominent maintenance lug boss 19.The installation portion 14 of sealing band 13 is covered on 12 last times of flange of the car door edge of opening of body panels 11, keep lug boss 19 elastic deformations and clamp flange 12 from car is inboard with both sides, the car outside, sealing band 13 is mounted on the flange 12 thus.So, clamp flange 12 from both sides, can sealing band 13 stably be fixed on the flange 12 thus with the installation portion 14 of sealing band 13.At this moment, make keep lug boss 19 elastic deformations and with flange 12 butts, can sealing band 13 more stably be fixed on the flange 12 through the elastic repulsion power that keeps lug boss 19 thus.
Further, on the outer peripheral face of the car inside side walls 18 of installation portion 14, form side-prominent shielding lug boss 20 in the car.Sealing band 13 is mounted to 12 last times of flange, between shielding lug boss 20 and installation portion 14 (car inside side walls 18), is capped the end insertion shape of the inside components (not shown) in the car.
Sealing bar 13 is through when extrusion forming sealing bar 13; Core 16 that cover to strengthen usefulness with the fringing material forming with polymeric material P1 is embedded in this core 16 in the installation portion 14 and integrated, can strengthen installation portions 14 and installation portion 14 stably is fixed on the flange 12 with core 16 thus.
The flange 12 of the car door edge of opening of body panels 11 is because end wise two dimension or three-dimensional ground crooked (comprising spiral), and the sealing band 13 that therefore is shaped to the straight wire through extrusion forming matches with the curved shape of flange 12, and ground is crooked to be assembled.Therefore, be embedded in the separated space portion 24 (with reference to Fig. 2) that states after core 16 end wises in the sealing band 13 are formed with predetermined distance with crooked freely along with the bending of sealing band 13.
Then, use Fig. 2～Fig. 8, the structure that is embedded in the core 16 in the sealing band 13 is described.And in Fig. 4～Fig. 8, for the convenience of explaining, the thickness direction of enlarge core 16, filling with each several parts such as polymeric material P2 amplifies diagram.
Like Fig. 2～shown in Figure 5; Core 16 carries out stamping-out processing through the core raw MAT'L 21 to long roughly band plate-like; Form alongst with a plurality of core sheet portions 22 of predetermined distance configuration and end wise should be a plurality of core sheet portion 22 connecting portions 23 connected to one another, and between adjacent core sheet portion 22, be formed with separated space portion 24.In the present embodiment 1, be provided with 2 row with connecting core sheet portion 22 connecting portion 23 each other, the separated space portion 24 between the adjacent core sheet portion 22 is divided into three zones through 2 row connecting portions 23.And, can also with connecting portion 23 be arranged to 1 row or 3 row more than.
About forming the core raw MAT'L 21 of this core 16; For the bendability of suitably strengthening being embedded with the sealing band 13 (installation portion 14) of core 16 and guaranteeing sealing band 13; For example; Core raw MAT'L 21 used thickness sizes (t) are that (for example, use sealing band as general car, preferable width is that 20～60mm, thickness are metal sheets such as non-metals plate such as 0.3～0.6mm) cold-rolling steel, spring plate, high tensile steel plate, stainless steel sheet, aluminum alloy to 0.15mm～1.0mm.These metal sheets can easily obtain.Each the core sheet portion 22 that is arranged on the length direction of core 16 for example is that 1～5mm forms with the size of the length direction of roughly the same shape, core 16 respectively.In addition, each the separated space portion 24 that is arranged on the length direction of core 16 for example is that (be preferably 1.0～2mm) forms 0.5～5mm with the size of the length direction of roughly the same shape, core 16 respectively.In addition, the corner portion that the both ends chamfering of the Width of the core 16 of each core sheet portion 22 becomes semicircle shape or both ends is with predetermined angular (for example 45 degree) chamfering, and the end nipple that prevents core sheet portion 22 is decoded strip of paper used for sealing 13 and externally exposed.
In addition; Like Fig. 6 and shown in Figure 7; In each separated space portion 24 of core 16, come to fill respectively themoplasticity synthetic resin (comprising thermoplastic elastomer) or rubber etc. and fill and use polymeric material P2, between adjacent core sheet portion 22, keep filling to use polymeric material P2 to form the roughly the same gauge of gauge with core sheet portion 22.Further; The whole surface of containing both sides (outer surface side of sealing band 13 and inner surface side) in the table of core 16 of core sheet portion 22 and connecting portion 23 covers with filling with polymeric material P2, the filling that covers core sheet portion 22 with the thickness (P2t) of polymeric material P2 be the gauge that is no more than the gauge of core sheet portion 22 (P2t≤t) and with being filled in separated space portion 24 interior filling continuous with polymeric material P2.Thus; Connect the filling that is filled in each separated space portion 24 each other with the filling that covers core sheet portion 22, connecting portion 23 with polymeric material P2, stably remain in the core 16 with polymeric material P2 being filled in the 24 interior fillings of separated space portion with polymeric material P2.
Further; As shown in Figure 2; Width W 2 through making the part that is positioned at the Width outside in the separated space portion 24 is less than the width W 1 that is positioned at inboard part, prevents to fill with polymeric material P2 to the disengaging in the Width outside and stably keep filling to use polymeric material P2.
In addition, as shown in Figure 3, be pre-formed in the end of the Width of core sheet portion 22 towards 22 outstanding projection 22a, the 22a of core sheet portion of adjacent other and also can obtain effect same as described above.At this moment, the width W 4 of the part that is positioned at the Width outside in the separated space portion 24 is less than the width W 3 that is positioned at inboard part.
So, with filling when being filled in the separated space portion 24 of core 16, with the whole surface of filling with polymeric material P2 covering core 16 with polymeric material P2.Thus; As shown in Figure 8; When profiled weatherstrip 13; Be filled with between the part of filling with the separated space portion 24 of polymeric material P2 in the part and the covering of fringing material forming with covering core sheet portion 22 among the polymeric material P1 and connecting portion 23, the fringing material forming is roughly the same with the gauge of polymeric material P1.In addition, the fringing material forming is set at below 3 times of gauge (t) (being preferably below 2.5～2 times) of core 16 with the gauge (P1t) of polymeric material P1.
Fill to use polymeric material P2 to do, can not hinder adjacent core sheet portion 22 near or away from degree under, compare with core raw MAT'L 21, hardness is little under the normal temperature, flexibility is high and the material that can engage with polymeric material P1 chemical with the fringing material forming.Filling use polymeric material P2 for example uses the durometer hardness that obtains according to JIS K7215 as HDA5～60 (being preferably HDA10～50) and than the material of fringing material forming with polymeric material P1 softness.Thus, prevent the axis bending of core 16 is produced obstruction with polymeric material P2, and guarantee to be embedded with the easy axis bending property of the sealing band 13 of core 16 through the fillings that are filled in the separated space portion 24.This filling use polymeric material P2 for example use with EPDM as main body can elastic deformation rubber or olefines can elastic deformation themoplasticity synthetic resin.
In addition, will fill when being filled in each separated space portion 24, even narrow space also can get into little resistance to flow with polymeric material P2.Therefore; Fill and to be filled can between the ora terminalis of core sheet portion 22 and connecting portion 23, not produce the space, prevent to be accompanied by the areal deformation (expansion goes out or caves in) of sealing band 13 of expansion or the contraction in the space that causes owing to temperature traverse with polymeric material P2.Further, in each separated space portion 24, fill the filling of roughly the same amount respectively and use polymeric material P2, can on whole length of the length direction of core 16, guarantee stable function.
In addition; In present embodiment 1; Like Fig. 4 and shown in Figure 5; To fill be filled in the separated space portion 24 with polymeric material P2 before, form non-adhesive agent layer 26 on the surface of core sheet portion 22 and connecting portion 23, non-adhesive agent layer 26 is between core sheet portion 22 and connecting portion 23 and filling are with polymer P 2.Avoid core sheet portion 22 and connecting portion 23 and fill through this non-adhesive agent layer 26, prevent that core 16 is difficult to bending, guarantee to be embedded with the bendability of the sealing band 13 of core 16 with polymeric material P2 set.This non-adhesive agent layer 26 is for example through formation such as organic siliconresin, oil, wax, paraffin.And core raw MAT'L 21 also can omit non-adhesive agent layer 26 when filling that to use polymeric material P2 be non-tack.
Then, use Fig. 9～Figure 19, the manufacturing installation and the manufacturing approach of sealing band 13 described.And in Figure 12～Figure 17, for the convenience of explaining, (16A～16C), the thickness direction of filling with each several parts such as polymeric material P2 amplify diagram to enlarge core 16.
At first, use Fig. 9 that the manufacturing installation and the manufacturing approach of core 16 are described.As shown in Figure 9, will export continuously through outlet roller 28 (core raw MAT'L output unit) end wise from the core raw MAT'L 21 that the decoiling unit 27 that is wound with the core raw MAT'L 21 of band plate-like is roughly supplied with and supply to the decompressor 29 (separated space portion formation unit).Between decoiling unit 27 and outlet roller 28, dispose resistance welding machine or engage core jointing machines 50 such as adhesive tape joining machine.The whole supplies of the core raw MAT'L 21 on will being wound on decoiling unit 27 finish and when being replaced by Next decoiling unit 27; Through core jointing machine 50, the terminal part that makes the length direction of the core raw MAT'L of supplying with from previous decoiling unit 27 21 is connected through welding or joint splicing tape etc. with the top portion of the length direction of the core raw MAT'L of supplying with from Next decoiling unit 27 21 and continuous.
Decompressor 29 has the partial sum that becomes core sheet portion 22 that stays in the core raw MAT'L 21 to be become the part of connecting portion 23 and removes the blanking die 30 of the part that is equivalent to separated space portion 24.Carry out stamping-out processing through 30 pairs of core raws MAT'L of this blanking die 21, staying the partial sum that becomes core sheet portion 22 becomes the part of connecting portion 23 and removes the part that is equivalent to separated space portion 24.Thus, be implemented in the separated space portion formation operation that core raw MAT'L 21 forms core sheet portion 22, connecting portion 23 and separated space portion 24.Form operation through this separated space portion, make to have core sheet portion 22, connecting portion 23 and separated space portion 24 but will not fill and be filled into core 16 in this separated space portion 24 (below be labeled as " not filling core 16A ") with polymeric material P2.
Then, do not fill core 16A and supply to the portion of storing 32, do not fill core 16A and temporarily store at this with the state of bending and store in the portion 32 from the traction of decompressor 29 usefulness nip rolls 31.Storing portion 32 disposes and is used to confirm the position transduser 33 (optical sensor that for example, comprise luminous element 33a and photo detector 33b) of the length (amount of storing) of not filling core 16A in specialized range that stored.Based on the output of this position transduser 33, outlet roller 28, decompressor 29, nip rolls 31 are carried out drive controlling, the length of not filling core 16A that stores in the portion of storing 32 is maintained in the specialized range.
Export and supply to non-adhesive agent layer formation device 35 (non-adhesive agent layer forms the unit) with storing continuously with constant speed with outlet roller 34 (core output unit) end wise at this not filling core 16A that stores in the portion 32.This non-adhesive agent layer forms the non-adhesive agent coating machine 36 of device 35 usefulness behind the non-adhesive agent of surface coating of not filling core 16A (core sheet portion 22 and connecting portion 23), is coated in the lip-deep non-adhesive agent of not filling core 16A with 37 pairs in drier and carries out drying and curing.Thus, be implemented in the non-adhesive agent layer formation operation that the surface of not filling core 16A forms non-adhesive agent layer 26 (with reference to Fig. 4 and Fig. 5).
And, can, separated space portion implement non-adhesive agent layer and form operation before form operation, form non-adhesive agent layer 26 on the surface of core raw MAT'L 21.In addition, also can obtain being pre-formed the core raw MAT'L 21 of non-adhesive agent layer 26, omit non-adhesive agent layer and form operation.
Then; Through extrusion forming device 38 (polymeric material filler cells) and leveling equipment 40 (appending filler cells); Be implemented in and do not fill core 16A when being substantially planar, be filled into the interior polymeric material filling work procedure of separated space portion 24 of not filling core 16A filling with polymeric material P2.Thus, be filled into the situation that cross sectional curve is processed in the separated space portion 24 of the core 16 behind the U word shape roughly with polymeric material P2 and compare with will filling, can more easily be filled in the separated space portion 24 with polymeric material P2 filling.And, use polymeric material P2 as filling, can enumerate themoplasticity synthetic resin, rubber.
Extrusion forming device 38 has the extrusion dies 39 of extrusion packing with polymeric material P2; In the future fill core 16A end wise and import to continuously in this extrusion dies 39, and will fill to supply in the extrusion dies 39 and come extrusion forming with polymeric material P2.Thus; Carry out will filling being filled into the once filling in the separated space portion 24 of not filling core 16A with polymeric material P2, and with filling the whole surface that covers both sides (outer surface side of sealing band 13 and inner surface side) in the table of not filling core 16A that comprises core sheet portion 22 and connecting portion 23 with polymeric material P2.
Thus, shown in figure 12, manufacturing will be filled with polymeric material P2 and once will be filled into core 16 in the separated space portion 24 (below be labeled as " once filling core 16B ").This once fills core 16B because filling is shunk " contraction " that might on the surface of the part that is equivalent to separated space portion 24, produce concavity with the moulding of polymeric material P2.
Like Figure 12 and shown in Figure 13, leveling equipment 40 is configured to a pair of leveling roller 41,42 and on above-below direction, clips and once fill core 16B.When the filling of supplying with from extrusion forming device 38 of once filling core 16B uses polymeric material P2 to be the state that can flow (during when themoplasticity synthetic resin during as the temperature more than the softening point; When rubber when not vulcanizing or before sulfuration finishes); Through core 16B is clipped in a pair of leveling roller 41 once filling of will supplying with from extrusion forming device 38, each roller 41,42 of rotating drive under the state that pressurizes between 42, draw with each roller 41,42 thus and once fill core 16B.At this moment, the filling on surface that forms core sheet portion 22 and connecting portion 23 is with the membranaceous or sheet of the thickness of the polymeric material P2 thin thickness before than above-mentioned pressurization, and forcibly mobile on length direction and Width.Thus; Carry out to fill the secondaries that being filled into fully in the separated space portion 24 with polymeric material P2 and fill (appending fillings), and the filling on the whole surface of both sides (outer surface side of sealing band 13 and inner surface side) becomes tabular surface with the surface of polymeric material P2 in the table of covering core 16.And the filling that covers the membranaceous or sheet of core sheet portion 22 and connecting portion 23 uses polymeric material P2 to be the gauge (P2t) of the gauge that do not surpass core sheet portion 22 and connecting portion 23 and continuous with polymeric material P2 with the filling that is filled into compressive state in the separated space portion 24.
Thus, manufacturing will be filled with polymeric material P2 and will be filled into fully in the separated space portion 24, and with filling the core 16 (below be labeled as " filling core 16C ") that covers whole surface with polymeric material P2.At this moment, shown in figure 13, might be from the both ends of the Width of filling core 16C (core sheet portion 22) extrude remaining filling and use polymeric material P3 with irregularly shaped.
Like Figure 14～shown in Figure 16; When in the polymeric material filling work procedure, once filling through extrusion forming device 38; When filling when using polymeric material P2, might go up generation protuberance 98 on the surface (surface or a side surface of both sides in the table) of the part of the separated space portion 24 that is equivalent to once to fill core 16B as rubber.
(a) shown in figure 14, when in the table of the part of the separated space portion 24 that is equivalent to once to fill core 16B, producing protuberance 98 on the surface of both sides, think that its reason can infer for as follows.Do not fill core 16A through in the extrusion dies 39 time; Fill with polymeric material P2 (elastomeric material) with compressive state be filled in the separated space portion 24 (represent among Figure 14 be the die face of both sides and extrusion dies 39 in the table of not filling core 16A gap size G about equally, double side acting is in compressive force P about equally the example of filling with polymeric material P2 in the table of not filling core 16A).Then; Once fill core 16B when extrusion dies 39 comes out; Fill and discharge from compressive state with polymeric material P2; Therefore compressed filling is with polymeric material P2 dilatational strain before, and both sides are filled with polymeric material P2 and expanded and go out to the outside of separated space portion 24 in the table of once filling core 16B, thus in showing generation protuberance 98 on the surface of both sides.
(b) shown in figure 15, produce protuberance 98 on the side surface in the table of the part of the separated space portion 24 that is equivalent to once to fill core 16B in the both sides, when on the opposite side surface, producing recess 99, think its reason (one of) can infer for as follows.Do not fill core 16A through in the extrusion dies 39 time; Do not fill core 16A offset on thickness direction, the gap size of both sides and the die surface of extrusion dies 39 might be different in the table of not filling core 16A (what represent among Figure 15 is not fill the gap size Ga of upside of core 16A greater than the example of the gap size Gb of downside).Its result; Die surface and a side (upside among Figure 15) of not filling the relief width of core 16A at extrusion dies 39; Fill and be filled in the separated space portion 24 with compressive state with polymeric material P2 (elastomeric material); But the narrow side (downside among Figure 15) in the gap is filled and is not filled into fully in the separated space portion 24 with polymeric material P2.Then, owing to once fill core 16B when extrusion dies 39 comes out, fill and discharge from compressive state with polymeric material P2; Side at relief width; Compressed filling is with polymeric material P2 dilatational strain, expands and goes out to the outside of separated space portion 24, produces protuberance 98.On the other hand, the narrow side in the gap is stretched by the swelling force of the filling of a side of relief width with polymeric material P2, fill with polymeric material P2 in the inboard of separated space portion 24 depression, generation recess 99.
(c) shown in figure 16, produce protuberance 98 on the side surface in the table of the part of the separated space portion 24 that is equivalent to once to fill core 16B in the both sides, when on the opposite side surface, producing recess 99, think that its reason (two) can infer for as follows.Do not fill core 16A through in the extrusion dies 39 time, double side acting might difference or change (what represent among Figure 16 is not fill the compressive force Pa of upside of core 16A greater than the example of the compressive force Pb of downside) with the compressive force of polymeric material P2 (elastomeric material) in filling in the table of not filling core 16A.Its result; In the big side of compressive force (upside among Figure 16); Filling is filled in the separated space portion 24 with compressive state with polymeric material P2, and in the little side of compressive force (downside among Figure 16), filling is not filled in the separated space portion 24 with polymeric material P2 fully.Then, once fill core 16B when extrusion dies 39 comes out, fill and discharge from compressive state with polymeric material P2; Therefore in the big side of compressive force; Compressed filling is with polymeric material P2 dilatational strain, expands and goes out to the outside of separated space portion 24, produces protuberance 98.On the other hand, in the little side of compressive force, the filling of the side that the power that is compressed is big stretches with the swelling force of polymeric material P2, fills with polymeric material P2 and caves in the inboard of separated space portion 24, produces recess 99.
Inferring the protuberance 98 of (b) situation produces respectively with (c) protuberance 98 of situation individually or compoundly.
Protuberance 98 for any one situation of (a)～(c); After once filling through extrusion forming device 38; Leveling roller 41,42 through leveling equipment 40 makes the filling of protuberance 98 (part expands) flow on the Width of once filling core 16B with polymeric material P2; Make protuberance 98 planarizations, the surface of once filling core 16B thus can form tabular surface.
And, when one group of leveling roller of impassabitity 41,42 makes protuberance 98 planarizations, can the leveling roller be set through appending in the downstream, stably make protuberance 98 planarizations.
In addition, only can in the table of once filling core 16B, carry out under the situation of planarization by the side surface in the both sides, when profiled weatherstrip 13, can the side that core 16 is configured to the planarization of core 16 be become in the sealing band 13 from outside appreciiable side.Thus, in sealing band 13 can not produce from the surface of outside appreciiable side concavo-convex.
After implementing the polymeric material filling work procedure, implement the trimming process step that deburring is carried out in the remaining filling of extruding from the both ends of the Width of filling core 16C (core sheet portion 22) with polymeric material P3 with edge-neatening apparatus 43 (deburring unit).Shown in figure 17, edge-neatening apparatus 43 is configured to a pair of deburring roller 44,45 and on above-below direction, clips filling core 16C.The outer peripheral face of the deburring roller 44 of this upside is provided with and is used for deburring is carried out in the remaining filling of extruding from the both ends of the Width of filling core 16C with polymeric material P3 cut-out blade 46.In addition, the outer peripheral face of the deburring roller 45 of downside is provided with corresponding to the sword dump tank 47 that cuts off blade 46.
This edge-neatening apparatus 43 with at a pair of deburring roller 44, clip between 45 from each roller 44,45 of state rotating drive of the filling core 16C of leveling equipment 40 outputs.Thus, fill core 16C, and will remove with 46 deburrings of cut-out blade with polymeric material P3 from the remaining filling that extrude at the both ends of the Width of filling core 16C through 44,45 outputs of each roller.At this moment; In present embodiment 1; Through with the big slightly width dimensions of size than the Width of filling core 16C (core sheet portion 22) remaining filling being carried out deburring with polymeric material P3, thereby the both ends of the Width of core sheet portion 22 are filled with polymeric material P2 and cover.Thus, the end nipple that prevents core sheet portion 22 strip of paper used for sealing 13 of decoding is exposed to the outside.But, when need not to worry the exposing of above-mentioned core sheet portion 22, can make that the two ends of Width of core sheet portion 22 are consistent carries out deburring.
Then; As shown in Figure 9; Fill and use under the situation of polymeric material P2 as themoplasticity synthetic resin; To supply to the fixing the handles device 48 from the filling core 16C of edge-neatening apparatus 43 outputs, make the filling of filling core 16C, between adjacent core sheet portion 22, keep effectively filling thus using polymeric material P2 with polymeric material P2 cooling curing.On the other hand; Fill and use under the situation of polymeric material P2 as rubber; To supply to the cure process device 48 from the filling core 16C of edge-neatening apparatus 43 outputs; The filling of filling core 16C heated with polymeric material P2 make its sulfuration sclerosis, between adjacent core sheet portion 22, keep filling to use polymeric material P2 thus effectively.Thus, completion is filled with the manufacturing of filling with the core 16 of polymeric material P2.
Then,, supply to core and store in the machine 51 (with reference to Figure 10) from fixing the handles device 48 (or cure process device 48) traction core 16 with nip rolls 49.
And, obtain being filled with under the situation of filling with the core 16 of polymeric material P2 from the outside, omit the manufacturing installation of core 16 shown in Figure 9 and the Fabrication procedure that omits core 16.At this moment, for example, configure volumes will be exported through the outlet roller end wise from the core 16 that this decoiling unit is supplied with around being filled with the decoiling unit of filling with the core 16 of polymeric material P2 continuously, supply to core and store in the machine 51 (with reference to Figure 10).
In addition, the top portion of the length direction of core 16 and terminal part can not filled with polymeric material P2 in specialized range respectively or after having filled with polymeric material P2, are removed.Thus; When end wise is exported core 16 continuously and is made the sealing band 13 that is embedded with this core 16; Can wait the terminal part of the length direction that makes core 16 easily to be connected continuously through welding, and be prone to find the connecting portion of core 16 afterwards with the top portion of Next core 16.
Shown in figure 10, store in the machine 51 at core, on above-below direction, alternately dispose many rollers 52, through these rollers 52, core 16 temporarily stores with the state that bends to zig-zag or narrow winding trail shape.In addition, the roller 52 of the part in many rollers 52 (for example central authorities roller) is arranged to and can be moved up and down, the position of the above-below direction through adjusting this roller that can move up and down 52, and adjustment stores the length (amount of storing) that stores the core 16 in the machine 51 at core.
Supply to core cold roll shaped device 53 (core forming unit) with storing the core 16 that stores in the machine 51 at this core; Through this core cold roll shaped device 53; Implement end wise continuously bending machining core 16 shape of cross section for the middle shape of cross section of regulation (below, be that the core 16 of middle shape of cross section is labeled as " core 16D " with shape of cross section.With reference to Figure 18) middle molding procedure.
At core cold roll shaped device 53; A pair of up and down format roll 54,55 disposes a plurality of on above-below direction, to clamp core 16 towards the downstream; In downstream; Shown in figure 18, forming surface 54Na, the 55Na of shape of cross section in the middle of the outer peripheral face of format roll 54N, 55N is provided with and is used for core 16 bending machining are become (shape of cross section of core 16 with compare the shape that expansion is opened) as the roughly U word shape of final shape of cross section.This core cold roll shaped device 53 will store the output when shape of cross section of core 16 is out of shape lentamente of core 16 that machine 51 supplies with from core through each format roll 54A～54N, 55A～55N, thus bending machining become in the middle of shape of cross section.
Then; The core 16D of middle shape of cross section supplied in the preheating machine 57 continuously, and this preheating machine 57 through having used diathermic heating etc. supplies to extrusion forming device 58 (press-forming units) at the core 16D that is preheated under the state of set point of temperature middle shape of cross section.
In this extrusion forming device 58, the sealing band 13 of the middle shape of cross section that enforcement will be stipulated (below, the sealing band 13 of middle shape of cross section is labeled as " sealing band 13A ".With reference to Figure 19) extrusion forming, the extrusion forming operation of the core 16D of shape of cross section in the middle of in the installation portion 14 of the sealing band 13A of middle shape of cross section, burying underground.Shown in figure 19; Extrusion forming device 58 possesses extrusion molding dies 59, this extrusion molding dies 59 be used for middle shape of cross section (shape of cross section of installation portion 14 be not processed to as the roughly U word shape of final shape of cross section, expand the shape of opening a little) sealing band 13 is carried out extrusion forming.The core 16D of shape of cross section in the middle of end wise is supplied with continuously in this extrusion molding dies 59; And in extrusion molding dies 59, supply with the fringing material forming from each supply port 60,61 continuously with the state that can flow respectively and use polymeric material, thereby the sealing band 13A (installation portion 14, hollow sealing portion 15 etc.) of shape of cross section in the middle of the extrusion forming with polymeric material P1 and the moulding of hollow sealing portion.Thus, the core 16D of shape of cross section in the middle of covering with polymeric material P1 with the fringing material forming, the core 16D of shape of cross section in the middle of in the installation portion 14 of the sealing band 13A of middle shape of cross section, burying underground.
