Definitions

  • the invention relates to a roller for guiding a flat track according to the preamble of claim 1.
  • Such a roller is known as a spreading roller for lateral spreading of a flat web DE 10 2005 021 467.3 A1 ,
  • Such a roller has a dense trimming obliquely outward brushes, bristles, bristle bundles or other projections, which perform a slight inclination in the direction of the nearest roll end at the web overflow and thus exert a spreading effect.
  • the object of the invention is to provide a roller on its circumference with a dense trimming of individual radially or radially obliquely projecting projections, even if the roller has a large length and / or a large diameter. It should also be possible to provide by tilting the projections in the direction of the nearest axial end of a spreading with similar or equal to good effect as the known roller. Despite low production costs, there should be no restrictions with regard to the diameter or the length of the roller. The solution results from claim 1.
  • any type of endless projection be it bead, ridge or the like, which are produced on the baseband, according to the invention of the invention perpendicular to the longitudinal direction of the Baseband or plus slope angle of the winding must be divided by cuts in order to exercise a function on the web running over it, eg spreading function. Otherwise, changes with the winding of the profile strip on the roll shell, the diameter of the projection to a reduced diameter at increased inclination. As a result, the projection would be clamped so much that it has no degree of freedom to any movement and can no longer function due to its increased inclination. This was completely overlooked in the prior art.
  • the moldings according to the invention are very simple in their shape and are easy to manufacture. It is an endless band with a thin rectangular cross-section as a base.
  • the underside of the band (pad side) is preferably smooth as the smooth roller surface that adapts to it.
  • the belt is so flexible that it can be wound in helical turns on the predetermined occupancy area of the roll and adapts to the curvature of the roll surface without warping and distortion.
  • the tape may be appropriately secured in the predetermined helical turns on the roll surface, e.g. by gluing with a suitable pressure-sensitive adhesive or similar
  • a tongue and groove connection, rivet connection, anchor pin / anchor hole connection is conceivable if the band by its shape and spring force does not adhere itself adhering to the roll surface.
  • the profile strip has only the function of a support for the web-supporting projections, which is inexpensive to manufacture and easy to install on the roller. Accordingly, it is also not desirable that the projections are arranged on helical lines, such as in the DE 3233214A1 shown; it is rather harmless that the circumferentially adjacent projections lie in the same radial plane of the roller. This may be due to the distance of the projections in the longitudinal direction of the profile strip, their distance from the edge and by the winding density (slope of the turns) of the profile strip and even be appropriate.
  • the claims 2 to 4 contain developments of the profile strip in terms of their function as a carrier of projections, which further enhance the application to the roll shell, or adapt to particular types of the projections.
  • the claims 8 to 10 include developments of the profile strip according to claim 7 for further development of the roller as a spreading roller for the overflowing web.
  • a dense trimming of the roll surface is achieved with projections, even if the profile strip is relatively wide and is therefore wound with a large pitch angle.
  • the development according to claim 3 allows the profile strips with greater thickness produce, so that the projections protruding therefrom, such as bundles of bristles well and securely attached and can be clamped so that does not discard the profile strip in inclination of the projections.
  • the flexibility required despite the thickness is achieved by cuts between the individual projections parallel to the base side of the band and in the direction of its width and can be influenced by the depth of cut perpendicular to the base side.
  • the profile strip can also be weakened by lateral or preferably perpendicular to the base side between the projections indentations such that the flexibility of the profile strip is sufficiently increased so far that the profile strip during winding on the occupancy area without distortion and distortion adapts to the diameter of the roller.
  • the development according to claim 4 shows a further possibility for a narrowest occupancy of the occupancy area with the profile strip at the desired density of the stocking with projections.
  • a preferred embodiment of the invention according to claim 5 has a trim of bristles, bristle bundles, fiber bundles, for example made of plastic, which are inserted into the band in one or more rows. They serve as support elements (contact elements) for flat webs and are-like normal free-running guide rollers used for the gentle guiding of flat webs widespread.
  • the bristles, bristle bundles u.dergl. are introduced into the profile strip such that they protrude on the side facing away from the roll surface side (base side), possibly with an inclination to one of the longitudinal edges (claim 7), protrude from the profile strip.
  • the bristles are sufficiently stiff to withstand the contact pressure of the web, on the other hand sufficiently flexible enough to tilt under the contact pressure towards the nearest roll end.
  • the bristle bundles take over the function of spreading, as from DE 10 2004 38165.8 known.
  • the invention makes it possible to produce the profile strip in a continuous process, ie for example by extrusion.
  • the projections, for example, bristles can then be introduced into the profile strip.
  • a particular aspect of the invention lies in the developments according to claims 6 and 7, characterized in that the projection is suitable by appropriate shaping itself as an expansion projection and thus with the band of the same material and a piece and in a single manufacturing process, e.g. can be made by extruding a corresponding profile.
  • the development according to claim 6 has the advantage that endless profile strips including the projections by extrusion, e.g. extruded from plastic, in particular thermoplastics, rubber or other soft or elastic materials and then formed by a cutting device in a simple process on one side single stand-alone projections.
  • the segmentation can be done with large cutting widths. In particular, the depth of cut of the segmentation is responsible for the flexibility of the profile strip
  • Claim 9 is an embodiment of the invention in which the profile strip is occupied with inclined in the width direction of the profile strip bristle bundles as spreading elements.
  • the moldings can be made in great length with the same shape and filled with bristle bundles.
  • the fact that the bristle bundles are inclined in the wound state of the profile strip respectively to the nearest roll end, is achieved in that each piece of the same profile strip are wound on the two roll halves, each with opposite pitch.
  • different profile strips can also be used for the left and the right half of the roller, which differ in that the projections / bristles / bristle bundles / fiber bundles have an inclination to the respective other longitudinal edge of the profile strip and an inclination component in the longitudinal direction of the profile strip. This makes it possible to ensure that the projections / bundles of bristles in the wound state have an inclination exactly in the axial plane of the roller, in which the base of the respective projection lies.
  • the expansion roller is freely rotatably mounted and is rotationally driven by the web or the spreading roller is driven such that the peripheral speed of the envelope is substantially equal to the web speed.
  • the winding is made so that this inclination points to the next roll end.
  • a band is preferably of the roll center wound to the roll end.
  • the other side of the roll is wound in the same way from the center of the roll, but this strip is mirror-inverted. If the assignment of the one assignment area - eg left of the longitudinal center of the roller - is designed as a right-hand thread, the assignment of the other occupation area - right of the longitudinal center - is performed with the mirror-image band as left-hand thread.
  • Fig. 1.1, 1.2, 1.3, 1.4, 1.5 show the cross section through a profiled strip 2 with a rectangular base band 3 and thereto homogeneously and flexibly mounted, integrally manufactured deformable profiles, here deformation profile or support section 1 called.
  • deformation profile or support section 1 There are profiled strips 2 with one, three and four support profiles 1 shown.
  • This deformation profile 1 are shaped so that they are connected in the clamping point 49 with the baseband 3 and on the opposite side have a contact surface 1.1 with a contact point 1.2.
  • the contact surface is shaped so that when overflow of a web-as described later at the contact point 1.1, the largest contact pressure is achieved.
  • the web overflowing the web with its contact force 11 at the contact point 1.2 generates a bending moment on the web Deformation profile 1 to the clamping point 49, which causes a movement of the contact surface 1.1 of the deformation profile to the right and thereby spreads the web, as described in AZ 10 2011 107 188.5.
  • the contact point 1.2 is thus offset from the clamping point 49 in the direction of one of the side edges of the base strip 3.
  • Fig.2.1 and 2.2 show the view of such a profile strip.
  • the profile strip 2 with the cross section for example according to Fig.2.1, that is, endlessly produced, for example, by extruding a plastic in the extrusion direction 5 with the base band 3 and the support profiles integrally attached thereto.
  • This profile is gem.
  • Fig. 2.2 in an additional operation by separating cuts 4 by means of a suitable cutting device so segmented that each longitudinal profile is divided into short, equal individual segments, ie projections 1, which correspond to the previously described form.
  • Claim 3 The separating cuts produce gaps of a certain width between the individual projections, so that the projections do not hinder the flexibility of the profiled strip / base band 3 relative to the roll shell and adjacent projections 1 also do not hinder each other in the tilting movement in the event of overflow of a tensioned web.
  • the individual profits / projections 1 have arisen, which correspond in shape to the projections described above and have the same function.
  • the angle of the section line 4 / columns with respect to the extrusion direction 5 is 90 °, preferably 90 ° plus the pitch angle of the wound on the support roller profile strip. As a result, the cutting line and the plane of the gap 4 between the adjacent projections 1 in the installed state remains axis-parallel.
  • the base 3 of the profile strips can be reinforced for better stability with inserted reinforcing bands, reinforcing fabrics, here wires or wire ropes 35 or flat steel strip. These reinforcements are also well suited to the mountings on the carrier roll.
  • the screw 13 shows a possible attachment with which the wound on the roller profile strip is fastened in particular at their longitudinal ends.
  • adhesives with sufficient adhesion are also known.
  • Fig. 1.5 shows a profiled strip 2 with a clamping device 7 with a clamping head 7.1 on a pin 7.2 and attached to the other side of the pin anchor pin 7.3.
  • Anchor pins and pins can pass through holes 8, which are used for fastening purposes in the Roll shell are introduced, are plugged. Then the anchor pin transversely sets and blocks the return movement. As a result, the clamping head 7.1 is pressed onto the edge of the wound profile strip 2 and the profile strip thereby clamped.
  • the Fig.1.3 and 1.4 serve to illustrate the spreading process.
  • fig.1.3 shows the force attack 11 on a spreader / projection 1.
  • the force application which is offset laterally to the clamping point 49 by the distance 12, creates a tilting moment, which causes the inclination of the projection 1 and the spreading of the overlying web.
  • Fig.3.1 is a profile in 2-legged (double webs 24) embodiment shown, with three such projections / support profiles 1 are arranged on a base tape.
  • each supporting profile 1 forms a hollow parallelogram, in which the double webs 24 are bridged by the contact surfaces fixed thereon 1.1 and support the contact surface 1.1 relative to the base 3 of the profiled strip 2.
  • the double webs 24 are inclined relative to the base to a side edge.
  • Fig.3.2 shows the cross section through a profiled strip 2 with 2 protrusions 1, as previously with reference to Figure 3.1 were described with the difference that here the force attack 11 is laterally offset very far out, so that the tilting moment and the spreading effect are greater.
  • the number of projections 3 arranged on the basis of a profiled strip in the width thereof is practically limited only by the pitch angle with which the profiled strip is to be wound up on the roll shell.
  • Fig.4.1 View of a profile strip
  • Fig. 4.2 shows such a single profile as a double web design with the profile width 41 which is determined by the width of the base band 3.
  • the contact surface is curved in the direction of the broad desr profile strip, so that the force attack 11 is approximately in the middle.
  • the contact surface 1.1 moves with the direction of movement 44 under the pressure of passing over the contact surface 1.1 under tension web in the direction of the side edge of the base tape 3 (arrow 44), wherein the double webs 24 deform to the right and increase their inclination.
  • the profiled strip shown is provided for the right half of the roller, the cross section of the profile strip for the left half of the roller is a mirror image.
  • the inner web 43 serves as a deformation limiter during deformation. He is in the interior of the basis of 3, double webs 24 and contact surface 1.1 existing profile to the base 3 as vertically upwardly facing, the contact surface 1.1 in the rest position without load but not touching web or vice versa as formed here, so depends on the Contact area 1.1, without touching the base in the unloaded state of the contact surface.
  • the base strip is extruded endless and then provided with the bristles.
  • Fig.5, 5.1, 5.2, 5.3 show the cross section through a profiled strip 2, which is provided in the longitudinal direction with a series of bristle bundles 19, which here have the function of the projections.
  • the bundles of bristles are straight (in the state wound on the roll of the profile strip: radially) or more or less (see below) inclined to a side edge of the profile strip. Such over the length of their roller half differently inclined bristle bundles can be used to generate different levels of spreading forces.
  • the profiled strips 2 are provided in the production with a thus endlessly extruded web-like bead 20 in the longitudinal direction of the base 3.
  • cuts in sections to be selected can be introduced into the beads transversely to the longitudinal direction, which weaken or interrupt the beads with regard to the bending stress of the profile strip, but the base strip 3 the profile strip 2 does not weaken significantly.
  • the beads give the foot of each bundle of bristles the necessary support.
  • Fig. 5.6 and 5.7 show views of this bristled profiled strips 2 with the baseband 3 and thus at the same time endlessly extruded bead 20 in the form of an inclined edge to the longitudinal edge of the base strip.
  • the bristles can stand individually; preferably Several bristles are combined into bristle bundles.
  • cuts in sections to be selected can be introduced into the beads transversely to the longitudinal direction, which weaken or interrupt the beads with regard to the bending stress of the profile strip, but the base strip 3 the profile strip 2 does not weaken significantly.
  • the beads give the foot of each bundle of bristles the necessary support.
  • Each bead singulated in this way can carry at least one bundle of bristles 19, depending on the desired density of the stocking.
  • Fig.5.8, 5.9, 5.10 show such a profile strip 2 in view and in cross-section through one of the cuts 4, which -we can not go down to the baseband 3.
  • Fig.5.9 ie base 3 and beads 20 extruded.
  • Fig.5.10 shows that then the beads are weakened by cuts 4, which do not reach into the baseband 3.
  • These cuts are in a plane perpendicular to the baseband, but obliquely to the longitudinal edges -90 ° plus the angle alpha, with which the profile strip is wound onto the roll shell.
  • the cuts are after winding exactly on axial planes of the roll shell, which is conducive to the flexibility and torsional flexibility of the profile strip.
  • Fig.5.10 shows that then the beads 20 are occupied between the cuts 4 with one or a series of bristle bundles.
  • the bristles are inclined to one of the longitudinal edges of the profile strip, preferably at an angle up to 45 °, preferably to 30 °, according to experience with good effect in plastic films between 20 and 28 °. It should be emphasized that the inclined bundles of bristles do not lie in a plane perpendicular to the longitudinal edge of the profile strip but in a plane offset by the angle alpha with which the profile strip is wound onto the roll shell. As a result, the inclined bristle bundles lie after winding the profile strip on the roll shell exactly on axial planes of the roll shell.
  • the profile strip 20 after Fig.5.9, 5.10 allows the bristles diagonally in one direction or the other. So it will be made of a support profile differently bristled profile strips. This has the advantage that from the same profile 3 ( Fig.5.9, 5.10 ,) a profile strip with inclination of the bristles to the left longitudinal edge and another with inclination of the bristles to the right longitudinal edge can be made.
  • the roll can be wound with these two types of profiled strip such that it receives on its right side to the longitudinal center of a bristle inclination to the right longitudinal end of the roll, and on its left side a bristle with inclination to the left longitudinal end of the roll.
  • the profiled strip 2 described above is in all these embodiments after the extrusion, after the sawing or milling procedure (claim 3 and / or claim 6) or after loading with bristles or bundles of bristles (claim 5) for producing the roller as an endless structure in many helical turns from the longitudinal center plane 16 with opposite but equal pitch angle alpha (17) on the right half 36 and left half 37 wrapped around the roll shell 14 and -as said- by appropriate measures such as screw -see Fig. 1.5 - or sticking to it.
  • an attachment to the ends of a profile strip is sufficient.
  • these can be preheated for ease of deformation, in addition or as an alternative to the measure of the cuts 4 (claim 3).
  • Fig. 1.4 shows a way to make the individual moldings so that when winding adjacent windings form no gap.
  • the profile strip receives at one longitudinal edge of its underside a follower tooth profile 10 and at the other longitudinal edge of its underside a follower profile groove 9, which formed during extrusion and which are assembled overlapping during assembly. This makes the assembly easier and more accurate.
  • the Figure 6 shows the view of a roller 14, the roll mantle 14 close together with projections 1, as shown by the Figures 1-4 are described is occupied.
  • the individual contact surfaces 1.1 thereby form a more or less closed overflow surface for the material web, with each individual contact surface having sufficient space for desired movements, in particular inclination movements in the direction of the closest roll end, with respect to its neighboring surfaces.
  • This mobility is ensured by the fact that by adjusting the profile strip 2 to the rounding of the shell of the support roller 14 is increased at each of the separation interfaces 4 by sawing or milling incision to a conical gap.
  • the exemplary embodiment shows a profile strip that has a single projection 1 over its width. The width of the base is therefore essentially limited to the width of the projection. Thereby, the profile band can be wound with a very small pitch angle 17 of the thread, the turns are close to each other, or even, as described Fig.1.4 shown, overlap a little bit.
  • Carrier roller 14 is applied, corresponds substantially to the width of the profile strip.
  • Fig.6.1 shows the view against the face of the roller. It can be clearly seen how by winding the individual separating cuts 4 to conical gaps 15 and the distance between the individual segments is increased. Thereby, the necessary flexibility of the segments is increased so that each element can move completely independent of its neighboring elements.
  • Fig. 7 shows the top view and the cross section of a support roller 14 with bristles to function as a spreading roller as described above with a right half 36 and left half 37 on both sides of the longitudinal center plane 16.
  • On each longitudinal half of the bristle bundles 19 are directed to the roll end inclined by the longitudinal median plane 16 of a respective profile strip helically in many, close to tight lying to the respective end of the roll shell turns on the roll shell 50th wrapped and fixed on it. (Claim 9)
  • the roll shell is wound helically from the longitudinal center plane 16 to the right and to the left, each with a profile strip, which in the embodiment according to Figure 8 provided with a web-like bead 20 on the base 3 and is occupied on the right side with inclined to the right and on the left side with inclined bristle bundles 19 to the left. Due to the helical winding each course has a pitch angle alpha to the longitudinal center plane 16, but in the opposite direction. Each bristle bundle is not inclined in the cross-sectional plane 18 perpendicular to the longitudinal edge 45 but with a pitch angle alpha.
  • each bundle of bristles comes to lie in one of the axial planes 21 of the roll shell during winding on the roll shell and the bristle bundles on the left side and the right side of the longitudinal center plane 16 are the same but directed opposite to the respective end of the roll shell.
  • the cuts 34 which lead to an increase in the flexibility, in particular of the bead 20, are not inclined in the cross-sectional plane 18 perpendicular to the longitudinal edge 45 but inclined to the pitch angle alpha. Therefore, all the cuts 34 occur during winding to lie the roll shell in one of the axial planes 21 of the roll shell.
  • the inclination of the projections or bristle bundles of a profile strip can change from the beginning to the end, for example, be steadily or gradually lower.
  • Such an embodiment is in Fig. 8 shown, wherein as projections here a bristling is applied.
  • profile strips can be made with different inclination of the projections / bristle bundles.
  • the Functional zones 40 adjacent to the longitudinal median plane 16, may, for example, have a slight inclination of the protrusions / bristles and therefore a slight spreading effect, the adjacent functional zones 39 have an average inclination and spreading effect and the functional zones 40 located at the end of the roller a strong inclination and therefore no strong spreading action.
  • the reverse embodiment may also be advantageous. Instead of the angle of inclination or in addition to the angle of inclination, the direction of inclination of the projections / bristle bundles in the functional zones can also be different.
  • the different profile strips in the functional zones 38, 39 and 40 are preferably connected to one another at the separating points by suitable measures and preferably wound onto the carrier roller without interruption.
  • the angle of the cut is not 90 to the extrusion direction, but increased by the amount of pitch angle, as described above.
  • webs 34 achieves the axis parallelism or alignment of these elements in each case an axial plane of the roller.
  • the inventive method to prepare the stocking of a roll with projections and in particular the stocking with spreading for a pulled over it under tension web by wrapping with flexible moldings, which in turn are occupied by the projections or spreading a one or more parallel rows, has many advantages , For rollers of different diameters, the same profile strips can be used.
  • the roll shell requires no special processing.
  • the roll jacket is not weakened by the attachment of the protrusions, bristles. Therefore, even long rolls and thick rolls can be filled with protrusions.
  • the density of the stocking depends neither on the dimensions of the roll nor on strength considerations. Advantages of the technically simple production also arise in terms of cost-effectiveness, Warehousing and assembly facilitation. Rollers can be made with variable length function. In addition to the spreading function, other functions can also be generated, for example without expanding properties in the case of straight protrusions / bundles of bristles.
  • the envelope is almost circular cylindrical, can serve as a guide roller for almost all types of webs. They are characterized in particular by their low, gentle contact with the web. But it also offers a very gentle and effective way of spreading for almost all types of webs. It needs no external drive, since it can be driven by the web, must be consistent with the. Since the spreading effect begins immediately after the web contact, the necessary wrap angle are low, they can be between 10 and 180 °. Likewise omitted complicated adjustments, the roller works like a normal guide roller and can be used at almost all points within a flat track guide.
  • the profiled strips 2 are extruded in the manufacture with 3 parallel over the width of the base strip 3 distributed beads 20.
  • the particular advantage of the profile strip as a carrier of projections according to this invention is that it can also be used with significantly larger roll diameters than previously cost with cantilevered projections close to dense and can be adapted to the desired function density.
