Description
Technical field
The invention relates to and along longitudinal direction, the metal belt plate of wide cut be cut into a plurality of rip cutting operating lines used (slitter line) above or two end edge portions of band plate excised and are cut on the trimming line (trimming line) of tool certain width, when the band plate after severing is batched again, can not make under band plate galled spots can be impartial and can give the belt band plate coiling tension applicator circulation endless belt (endless belt) used of sufficient tension force, especially about a kind of, give sufficient coiling tension, even if make band plate surface be attached with the circulation endless belt with joint-cutting (slit) that also must prevent the relative slippage of band plate and Cyclic Rings interband under the state of roll-in oil or anti-corrosion oil.
Background technology
Utilize the prior art of difference of friction coefficient of table back layer of the circulation endless belt of belt band plate coiling tension applicator to have the applicant's Japanese Patent No. 1361033 and No. 3769730.These special permission technology are to use synthetic resin that friction coefficient is large and the material of synthetic resin system in the superficial layer material that is contacted with an example of metal band plate, back layer material is used the little material of friction coefficient of the syntheticfibres systems such as polyester, but when there is the band plate of oiling on band plate surface, because oil film significantly reduces friction force, cause the slippage of band plate and Cyclic Rings belt surface, cause this endless belt not synchronize and rotate with the coiling speed of band plate, result can produce scratch on band plate surface maybe cannot there is sufficient tension force, therefore when these technology are attached with oil on band plate, can not be suitable for.
For addressing the above problem, the continuous up-to-date technology of being researched and developed No. 2701004th, Japanese Patent by the applicant, it is with the skin of same material not, interlayer and internal layer form circulation endless belt, and make interlayer contain lubricating oil and the lubricating oil via that is through to internal layer by interlayer is set, make lubricating oil be infiltrated into the rear side of circulation endless belt, thereby reduce the friction coefficient of this circulation endless belt rear side, or in the surperficial outer layer side of circulation endless belt, ridge design is set, by suppressing its protuberance, in band plate surface, with the removal oil film of part, improve the friction force of this endless belt and band plate, in order to dwindle the friction coefficient with this endless belt rear side, but in fact, according to described in its claim claims 1, when an endless belt perforating (via) of plane, cannot remove by the oil film of the band plate of oiling, therefore do not conform to practicality, the circulation endless belt that the Surface sheet by having most recesses described in claims 3 forms meets practicality.
But progress or band plate surface-treated variation due to the roll-in of metal belt plate in recent years (calendering) technology, or in order to continue compacting (press) the shaping processing of rear engineering, having in recent years the surperficial band plate easily sliding has the gesture of increase gradually, in addition the major part of these band plates that easily slide all scribbles anti-corrosion oil or scribbles lubricating oil for press process, even if therefore use special endless belt described above, its speed of batching band plate can only reach the degree of approximately 50 meters of per minutes at most, while implementing to batch over the high speed of this boundary, because reaching moment, remove oil film, so that cause the deficiency of the friction force between endless belt protuberance and band plate, produce the slippage of circulation endless belt and significant limit production (productivity).
Again, the belt band plate coiling tension applicator providing according to above-mentioned Japanese Patent the 2701004th is to be equipped with the pressing mechanism of each a pair of circulation endless belt up and down by driving, utilize the clamping band plate of this upper and lower circulation endless belt sandwich-like, by increase and decrease, be attached to the pressure adjustment coiling tension that adds pressure cylinder (press cylinder) of this pressing mechanism simultaneously, yet because Cyclic Rings belt surface cannot be removed the oil film of band plate completely, cause the tension force of the band plate that thickness is larger to become deficiency, otherwise during the band plate of thinner thickness, but can be subject to the crunch of the convex projection of Cyclic Rings belt surface, and the distortion that produces concavity on band plate surface, therefore be not suitable for the band plate of thinner thickness.
While pressing above-mentioned prior art, while causing part or all of endless belt not synchronizeed with the coiling speed of band plate if the friction force of Cyclic Rings belt surface is not enough, because band plate surface there will be slip vestige (slip mark), become the fatal defect of batching operation, do not become qualified goods, generally coiling speed is reduced to operation reluctantly in 50 meters of following situations of per minute for this reason.For overcoming this shortcoming, thirst at present a kind ofly originally still can really keeping synchronize with band plate speed under the high speed of 200 meters of the per minutes of all maximum speeds or 300 meters rotating and without the improvement circulation endless belt of the worry of generation slip vestige at operating line.
Protuberance with tape loop top layer is got rid of oil film, and the oil content being excluded can be collected in the recess between protuberance and then drain into the tape loop back side from being formed at the outage of this recess, but the oil content being gathered in without the recess of outage still remaines in home position, because there being the oil film of this residual oil content easily to cause slippage, therefore cannot be applicable to need larger coiling tension thicker band plate, i.e. the thickness range of its applicable band plate restricted (that is not being suitable for thick band plate).
Or when this tape loop superficial layer has recess or jog, at protuberance, can produce higher face presses, therefore during compared with the thick band plate of thin plate because the surface with concaveconvex shape clamps retainer belt plate, therefore have the defect of concavo-convex impression on band plate, and pressure when wanting to avoid this defect and reducing the folder of endless belt, can there is the not enough or inhomogeneous of coiling tension or slippage occurs, cannot stablize and batch band plate, even the disappearance of unclamping with coiled sheet of batching.
As mentioned above, prior art is the friction force that utilizes band plate surface and tape loop surface, but because it cannot get rid of the oil content (oil film) on band plate surface completely, therefore the countermeasure of expecting unique is to manage to make the friction coefficient on band plate and circulation endless belt top layer to be greater than the friction coefficient of circulation endless belt rear side, but owing to there being the state that oil film is remaining, friction force is had a limit by oneself.
But, while having the continuous rolling of band plate to manufacture on the surface of band plate formed several microns (there is the micro concavo-convex (with reference to Figure 18) of plated film on the surface roughness of (m) (with reference to Figure 17) or band plate surface.The surface roughness of metal belt plate is difference by its purposes, the surface roughness of automobile or family's electrical article steel band used for example, the clarity of considering the compressing of its successive process or completing after application etc., be processed into suitable surface roughness, common maximum rugosity (Rmax) approximately 1 (m to 5 (m and comprehensively blazoned concavo-convex at band plate, the spacing of the protuberance that this is concavo-convex (pitch) number PPI (peaks per inch, be the protuberance number of each inch) be generally 100 left and right, that is say, when the PPI on band plate surface is 100/25.4mm, in every 1mm length, there is the protuberance that 4 number microns are high repeatedly exist continuously and form convex-concave surface.
Summary of the invention
The present invention makes in view of having of prior art problem to be solved, its object is to have several microns of surface roughnesses on band plate surface or the micro concavo-convex of band plate surface coating in mind, and for catching the micro concavo-convex on band plate surface, in tape loop outer surface, with the majority of determined interval cutting institute depthkeeping degree, connect airtight joint-cutting (slit), make the small protuberance on band plate surface eat each joint-cutting part into (entering), seizure makes to connect airtight when residuing in the oil film on band plate and zero-lash each joint-cutting is produced negative pressure by be pulled distortion cavity of the small protuberance of this wedging, so be contacted with the most joint-cutting portion of the tape loop on band plate surface, all can bring into play the band plate with oil residues film as the effect absorption of vacuum pump, therefore can provide a kind of belt band plate coiling tension applicator circulation endless belt with joint-cutting (cutting gap) used that applies coiling tension certain under relative slippage is not occurring.
In order to solve above-mentioned problem, the invention provides a kind of circulation endless belt with joint-cutting for belt band plate coiling tension applicator, in this belt band plate coiling tension applicator, in the band plate along wide cut longitudinally, after being cut into a plurality of, this band plate furled in the way of batch up gear, a part for the two sides side that is equipped on each band plate of plural circulation endless belt subtend is formed to common clamping face, the wipe contact that utilization is batched each mobile band plate and above-mentioned each Cyclic Rings interband towards band plate batch up gear drives the endless belt that respectively circulates to make its each loopy moving independently, by the above-mentioned pushing that respectively circulates endless belt inner surface, impose on the certain coiling tension of each band plate, it is characterized in that: use at least two layers of above not same material to form and form above-mentioned circulation endless belt by outer surface layer and stacked the closing of inner surface, and in the outer surface of this circulation endless belt contacting with each band plate, to the length direction of this circulation endless belt with predetermined distance cutting prescribed depth and connect airtight mutually, can eat into and be pulled by this protuberance for the small protuberance on each band plate surface and be out of shape a plurality of joint-cuttings (slit) that become small cavity and negative pressure occurs.
The present invention who has the means that solve above-mentioned problem can bring into play following excellent effect.
Fine concavo-convex for the surface roughness of several microns on band plate surface and the plated film on band plate surface, a plurality of joint-cutting of the formation prescribed depth of all connecting airtight at the outer surface of circulation endless belt is in order to catch the micro concavo-convex of the micron size on band plate surface, even if the protuberance of the micro concavo-convex on band plate surface is eaten into being formed in the above-mentioned joint-cutting of circulation endless belt, so can catch the band plate that remain oil film by these joint-cuttings, there is not one walking circulation in the situation of slippage in result can make to circulate endless belt and the band plate that remains oil film.
Meanwhile, the Cyclic Rings band clamping pressurization with upper and lower of band plate sandwich state can be carried out and batched operation, make to circulate each joint-cutting portion of endless belt is pulled and deforms by the micro concavo-convex on band plate surface at compressed state, so each joint-cutting in this distortion partly produces small cavity, and this hollow sectors becomes vacuum state negative pressure, produce sucking action absorption with the band plate surface of oil residues film, promote and connect airtight power.
As mentioned above, because the concavo-convex protuberance on band plate surface can be eaten into being formed in a plurality of joint-cuttings of outer surface layer of circulation endless belt, the effect that can produce vacuum pump in these joint-cuttings of this Cyclic Rings belt surface layer simultaneously, seizure remains the band plate of oil film, so when batching band plate by winding machine, can apply by Cyclic Rings band the coiling tension of regulation, can eliminate the relative slippage of circulation endless belt and band plate simultaneously, certain synchronous walking, therefore without abrasive worry.In addition, even if the larger band plate of thickness also can, with the control tension force of stress ratio, therefore can be applicable to the band plate of various thickness ranges.
By in the past, by the band coiled sheet of oiling (sheet belt coil), be to utilize the irregular circulation endless belt of surperficial tool be commonly called as No. 2701004th, the adhesive-bonded fabric pad of tension mat (tension pad) or Japanese Patent, though imperfect but with the following careful operations of speed of 50 meters of per minutes, and needn't worry that band plate surface is scratched while using circulation endless belt of the present invention, therefore can, in the maximum speed running of original operating line, improve productivity.
Again, device group using the device shown in Fig. 2 and Fig. 3 as four sections of circulation endless belt as shown in FIG. 11 and 12 enters, go up two sections of uses dry circulation endless belt of using in the past, during lower two sections of circulation endless belt that use oiling materials of the present invention, can use the band sheet material of Cyclic Rings tape handling all (various), though and oiling, without the band plate of oiling, all can needn't worry to abrade, pollute operation under vestige, therefore the raising for quality and capacity rating has contribution.
In addition, the surface of circulation endless belt of the present invention is but No. 2701004th, Japanese Patent concavo-convex, even therefore thin plate also can relievedly under impression batch operation not producing with sheet material.
Very and, for by without a doubt applicable of also batching of the senior surface completion material of the household electrical appliances that batch or scribble for press process lubricating film of the band plate of the automobile of oiling.
Again, during according to the technology of second aspect present invention, can make roll-in oil or the antirust wet goods oiling on band plate surface get rid of to the most through hole that is arranged at the outer surface of circulation endless belt, therefore can prevent from forming the oil film of antirust wet goods between the surface of band plate and outer surface, further improve the outer surface of circulation endless belt and the surperficial slippage of band plate, in addition, the part of antirust wet goods that is rejected to the inner surface of circulation endless belt by through hole can be used as the lubricated use of the inner surface of circulation endless belt, so can reduce the supply number of times of lubricating oil, can keep again friction coefficient between its surperficial member of this inner surface and crimping in certain little value simultaneously, thereby further promote the loopy moving of circulation endless belt.

The specific embodiment
With accompanying drawing specific description implement optimal morphology of the present invention under.
In figure, 1,2 is belt band plate coiling tension applicator, is in order to fixed coiling tension is given via circulation endless belt 3 to the device of (applying) metal band plate 4 processed.As shown in Figure 1, the band plate 4 that these tension applying devices 1,2 (Fig. 1 illustration belt band plate coiling tension applicator 1) make to be arranged on the place ahead of band plate batch up gear 5 batches in the way of mobile route.This kind of tension applying device for example has so-called " elliptical form (speciallyying permit No. 3679730) " as shown in Figures 1 and 2, or patterns such as " belt pulley (pulley) formula (speciallyying permit No. 1361033) " as shown in Figure 3.
Wherein, the belt band plate coiling tension applicator 1 of the elliptical form shown in Fig. 1 and Fig. 2 is main by applying body 11 and the loopy moving circulation endless belt 3 that this pressure applies body 11 peripheries that is arranged at freely and formed in order to pushing the pressure of circulation endless belt 3 inner surfaces.2 masters of belt band plate coiling tension device of belt pulley type shown in Fig. 3 are by a pair of belt wheel 21, the circulation endless belt 3 that is set around this pair of belt wheel 21 freely of circulation and formed in order to push the pressing plate 22 of this circulation endless belt 3.
Circulation endless belt 3 is laterally most configurations and by the setting of these circulation endless belt subtend Shang Xia 3.Each endless belt 3 that circulates can be distinctly loopy moving independently.Belt band plate coiling tension applicator 1,2 is provided with the drive source that drives circulation endless belt 3, and the endless belt 3 that therefore the circulates loopy moving of can not relying on oneself itself, only by the frictional engagement loopy moving of 4 of itself and mobile band plates.That is, unless circulation endless belt 3 engage with band plate 4, otherwise can loopy moving.
The endless belt 3 that respectively circulates of upper and lower subtend setting forms the common clamping face of each band plate 4 between mutually, both sides at this common clamping face, it is upper and lower sides, upper and lower parallel setting is in order to give body 11 or push plate 22 by the inner surface of each circulation endless belt 3 towards the pressure of foreign side's pushing respectively, by this pressure, give body 11 or push plate 22, via circulation endless belt 3, from upper and lower two direction crimping clampings, pass through the band plate 4 of this common clamping face.
Even band plate 4 by the endless belt 3 that circulates up and down relatively to outer surface 31a between, it is common clamping face, utilize pressure to give body 11 or push plate 22 is crimped on band plate 4 from the inner surface 33a of the endless belt 3 that circulates up and down by circulation endless belt 3, utilize the frictional engagement of 4 of itself and mobile band plates to drive circulation endless belt 3, therefore can not occur under slippage with each mobile band plate 4, the endless belt 3 that makes respectively to circulate is respectively independently toward moving direction loopy moving.
In addition, by given the sliding friction power between the inner surface 33a of body 11 or push plate 22 and circulation endless belt 3 by above-mentioned pressure, that is say, the inner surface 33a of crimp cycle endless belt 3, make to give body 11 or push plate 22 by the pressure of the circulation endless belt 3 with the frictional engagement loopy moving of mobile band plate 4 and serve as braking tool (brake) and use, make position produce coiling tensions in each band plate 4 of 1,2 of band plate batch up gear 5 and belt band plate coiling tension applicators.
Above-mentioned circulation endless belt 3 is that the three layers of different materials such as outer surface layer 31, interlayer 32 and inner surface layer 33 that become by the material with flexibility are formed.Outer surface layer 31 is that circulation endless belt 3 is positioned at the part in outside, inner surface layer 33 is positioned at inner side part while using for circulation endless belt 3 (giving the side that body 11 or push plate contact with pressure) while using, and interlayer 32 is the parts by the clamping of above-mentioned outer surface layer 31 and inner surface layer 33 sandwich-like.
Wherein, the outer surface 31a of the outer surface layer 31 of circulation endless belt 3 is as above-mentioned, and between mobile band plate 4, slippage does not occur completely, and is integral with band plate 4 function of bringing into play mobile circulation endless belt 3.The outer surface 31a of circulation endless belt 3 is that the material that is greater than the friction coefficient of inner surface 33a by friction coefficient is made.For the connecting airtight band plate 4 of softness, obtain desired friction force, outer surface layer 31 is preferably used the materials such as neoprene, polyamine base methyl ethyl resin or Vinyl chloride resin that friction coefficient is large to make.
Again, the inner surface 33a of the inner surface layer 33 of circulation endless belt 3 is in order to give the sliding friction power of 22 of body 1l or push plate by itself and above-mentioned pressure, make band plate produce the function of coiling tension, therefore this inner surface layer 33 needs to use the little and tool flexibility of a kind of these outer surface layer 31 friction coefficient but incompressible for example vinyl fiber or poly-ester fibres are that synthetic resin fiber is made, and so can guarantee that inner surface 33a and pressure gives body 11 or the surperficial easy glide of push plate 22.
32 compression elastic materials by tool flexibility of interlayer of circulation endless belt 3, the polyamine base ethyl formate resin that for example foams forms.The interlayer 32 of this kind of resilient compressibility can recover original thickness by fast speed when pressure relief is given the compression (flattening) of body 11 or push plate 22.
Circulation endless belt 3, as shown in Figure 4 A, its total length with determined interval from outer surface 31a to the inside surperficial 33a be equipped with through hole 34.Path when these through holes 34 that are arranged at circulation endless belt 3 become the part of oiling on band plate 4 surfaces surperficial 33a flows out to the inside by the outer surface 31a with its crimping, so a part for oiling can flow to inner surface 33a and inner surface 33a is lubricated by this through hole 34.
In addition at the outer surface 31a of the outer surface layer 31 of above-mentioned circulation endless belt 3, the surface roughness of several microns (with reference to Figure 17) that coordinates band plate 4 surfaces, or the micro concavo-convex (with reference to Figure 18) of the plated film on band plate 4 surfaces, from the surperficial cutting contacting with band plate 4 for example the joint-cutting (slit) 35 of institute's depthkeeping degree of about 0.5-1.0mm for the jog of several microns that catches and attract band plate 4 surfaces, above-mentioned joint-cutting 35 is that cutting with determined interval majority is in the total length of circulation endless belt 3, and the length direction of each joint-cutting 35 and circulation endless belt 3 rectangular across its overall with (with reference to Fig. 8), the equal configured in parallel of each joint-cutting 35 of while.
Be arranged at each joint-cutting 35 of outer surface 31a of circulation endless belt 3 when the tabular surface state contacting with band plate 4, to be zero-lash tightlock status, in other words, the side of two inner sides of each joint-cutting 35 is to connect airtight mutually to become zero-clearance state, and this kind of tightlock status stretches to the overall with of circulation endless belt 3.
When being stressed, above-mentioned circulation endless belt 3 gives the pushing of body 11 or push plate 22, or move while being subject to tractive force because of band plate 4, there is elastic deformation in the superficies layer 31 that is provided with joint-cutting 35, the inside that result is connected airtight each joint-cutting 35 of zero-clearance state can become empty 35a (with reference to Fig. 7) because of this elastic deformation.
Inferior explanation is implemented under the acting on of circulation endless belt of optimal morphology of the present invention.
The band plate 4 being batched by band plate batch up gear 5 is by being arranged in mobile route way, and the belt band plate coiling tension applicator on portable cord is 1,2 o'clock, is applied in coiling tension.While using the circulation endless belt 3 of above-mentioned structure, as shown in Figures 1 and 2, when belt band plate coiling tension applicator 1, this band plate 4 is stressed and gives body 11 and depress, and when the belt band plate coiling tension applicator 2 shown in Fig. 3, depressed by push plate 22 and clamp band plate 4 by the both sides up and down of band plate 4.
When there is antirust wet goods oiling a on band plate 4 surfaces, at this band plate 4, enter while circulating up and down between endless belt 3,3, can be because of the pressure of the endless belt 3 outer surface 31a that are subject to circulating, surrounding's another part that a part of this oil a can be removed to circulation endless belt 3 flows in the through hole 34 arranging towards inner surface 33a from the outer surface 31a of circulation endless belt 3, this part that flows into the anti-corrosion oil a in through hole 34 flows to inner surface 33a and the pressure of the lubricated circulation endless belt 3 of inner surface 33a and gives between body 11 or push plate 22, and its mutual friction drag is reduced.
As mentioned above, via pressure, give the outer surface 31c of the endless belt 3 that respectively circulates on two surfaces of the band plate 4 that body 11 or push plate 22 crimp surface have antirust wet goods oiling a, in its overall with and connected airtight zero-lash cutting along the total length of this endless belt 3 with determined interval and have most joint-cutting 35.
Two surfaces at band plate 4, by the micro concavo-convex of its surface roughness or band plate surface coating, the jog with the mountain valley of several microns, due to the mountain part in the surperficial small mountain valley of band plate 4 be also protuberance eat respectively into (entering) connect airtight and zero-lash each joint-cutting 35 in, therefore the small protuberance on band plate 4 surfaces can be eaten in these joint-cuttings 35, in other words, these joint-cuttings 35 can catch the band plate 4 with oil film, and the endless belt 3 that therefore circulates can make band plate 4 that one loopy moving under slippage is not occurring.
In this occasion, if use as specially permit the circulation endless belt 6 (with reference to Fig. 9) of the ditch with larger gap of No. 2701004, it is connected airtight in band plate 4 and during loopy moving, due in ditch portion space 61 parts without (disappearance) Cyclic Rings carrying material (with reference to Fig. 9 A), therefore become rigidity deficiency, yielding slippage (slip) consequently cannot catch band plate 4 (with reference to Fig. 9 B) really.But, when of the present invention, because circulation endless belt 3 used is provided with most zero-lash joint-cuttings that connect airtight 35, therefore each joint-cutting 35 part gaplesss can be integral opposing tractive force, simultaneously can by these joint-cuttings 35 (the especially bight of joint-cutting) catch band plate concavo-convex protuberance, make this circulation endless belt 3 and band plate 4 be integral loopy moving (with reference to Figure 10 A).
Again, above-mentioned outer surface 31a and the outer surface layer 31 that is provided with the circulation endless belt 3 of joint-cutting 35 is to be formed by soft elastic body, therefore at the oiling Surface Contact of band plate 4 when the surperficial state of each joint-cutting 35 of outer surface 31a is subject to giving the thrust pressure of body 11 or push plate 22 from the tractive force of band plate 4 or pressure, the small protuberance by band plate 4 of these joint-cuttings 35 eat into part just can play elastic deformation.This distortion can make most joint-cutting 35 of forming at the length direction of circulation endless belt 3 and Width inner produce by eat into the small protuberance of band plate 4 centered by small empty 35a (with reference to Figure 10 B).
The oiling surface that the surperficial reason that inside is formed with each joint-cutting 35 of empty 35a is in contact with it the band plate 4 of (butt) seals, and does not therefore have outside air and flows into.The tightlock status spread of joint-cutting 35, in the same full width orientation of circulation endless belt 3, therefore also can flow into from the cross direction of circulation endless belt 3 inside of each joint-cutting 35 without air again.
So, can make to eat the negative pressure that becomes vacuum shape into the small empty 35a centered by the small protuberance of the band plate 4 of the inside of each joint-cutting 35, produce sucking action, and the adhesion force on 3 pairs of band plate 4 surfaces of this circulation endless belt is further promoted on the just adsorbable surface that has the band plate 4 of residual oil film of 35 of each joint-cuttings that this produces sucking action.
The effect of the joint-cutting 35 that the majority arranging at the outer surface 31a of circulation endless belt 3 connects airtight, confirms via the experiment of Figure 13 and Figure 14 and the experimental result of Figure 15 and Figure 16.
Particularly, use between joint-cutting 35 that every the endless belt sample (sample) that is changed to 15mm spacing by 1mm spacing (pitch), to implement the joint-cutting interval that the experimental result shown in Figure 13 obtains as shown in figure 15 less, the result that confining force is stronger.In addition, be selected outer surface layer 31 (soft resin), the hardness that changes resin is carried out the comparative experiments of confining force, and results verification is as follows, and 65 ° of persons of hardness show peak:
40 ° 50 ° 65 ° 85 ° of hardness Hs
Confining force value 5kgf 8kgf 20kgf 12kgf
In addition, the comparative experiments result that the Cyclic Rings carry sample that is formed with all styles of (pattern) shown in Figure 14 (A)-(F) for the surface of circulation endless belt 3 carries out confining force obtains result as shown in figure 16.Other samples that are formed with beyond the circulation endless belt of joint-cutting 35 of the present invention all can, with the increase and decrease confining force of stress ratio, not confirm that these other samples all do not conform to practicality.
By above-mentioned experimental result, can be demonstrate,proved, according to the present invention, outer surface layer 31 at the outer surface 31a of the circulation endless belt 3 contacting with band plate 4 utilizes the above-mentioned material with suitable elastomeric oil-resistant synthetic rubber or synthetic resin system to form, simultaneously the full bandwidth cutting majority to the right angle orientation of the length direction of this endless belt 3 determine the small joint-cutting 35 at interval, thereby the small protuberance of majority on band plate 4 surfaces is eaten in these joint-cuttings 35, obtain desired confining force.Through experimental result, the coiling speed that this confining force can sufficient corresponding per minute 300m.
Above-mentioned is the example of desirable example of the present invention, but the present invention is not limited by this example, can in the present invention discloses scope, do multiple change and modification.For example at example, pass the imperial examinations at the provincial level and show the circulation endless belt of three-layer structure, but also can use, there is flexibility and the little material of friction coefficient as inner surface layer 33 and can be for the soft elastomer of most joint-cuttings 35 of cutting degree of depth 0.5-1.0mm left and right as outer surface layer 31 material, use two kinds of different materials, form circulation endless belt 3.
