Definitions

  • the invention relates to a profile strip of the type specified in the preamble of claim 1.
  • a profile strip of this type known from DE-OS 24 00 7kl consists of a lamellar body made of aluminum, which is provided with an elastomeric surface layer.
  • the production of the two parts of the profile strip is complex. Attaching the surface layer requires extreme care and is therefore time consuming. The surface layer can hardly be renewed, so that a worn profile strip must be replaced by a new one. The surface layer tends to peel off especially under the forces exerted by the web.
  • a profile strip which consists of a C-shaped metal rail with claw-shaped bent-in legs and a support glued to the straight back.
  • the pad is a plastic adhesive covering in the form of a single-sided adhesive strip.
  • the edges of the pad must end at a distance from the edges of the back, because there the adhesive strength is insufficient and the pad can peel off.
  • the area that can be used to transmit power to the web is limited; the durability of the support leaves something to be desired because the centrifugal force works on the support. Attaching or replacing the pad for repair purposes is tedious.
  • adhesive is often used to increase the adhesive strength of the support.
  • the invention has for its object to provide a profile strip of the type mentioned that is durable despite the rough working conditions when spreading webs of goods and is characterized by cost-effective manufacture and easy assembly and repair options.
  • the support is attached to the base body responsible for the mounting by means of the intermediate support
  • the intermediate support can be produced from a material that is very tight to the support.
  • the support can therefore no longer detach itself from the intermediate carrier under the forces exerted by the web.
  • the support can also extend over the entire detachable width of the intermediate carrier.
  • the intermediate carrier together with the support can be a prefabricated component which can be produced practically endlessly inexpensively, then cut to the required length and pushed onto the base body as required.
  • the clamp grip of the intermediate carrier on the base body is sufficient to reliably withstand the centrifugal forces on the one hand and the forces of the material web on the other hand.
  • the clamp handle holds the intermediate carrier securely on the base body in the longitudinal direction with the support when the material web spreading roller is working.
  • the pretension is dimensioned such that it is easy to pull on the intermediate carrier, as is its rapid removal for repair purposes. Because of the simple, inexpensive manufacture of the intermediate carrier with its support, it can be thrown away when the support is worn and replaced by a new section. It is favorable that, because of the clamp handle, no consideration needs to be given to the material pairing between the intermediate carrier and the base body, so that the material of the intermediate carrier with regard to the inexpensive production and good connection to the support, the base body, however, with regard to the structural strength, the sliding properties and its corrosion resistance, can be freely selected in operation.
  • the grip of the intermediate carrier on the base body which at the same time ensures a frictional connection and a positive fit, ensures that the intermediate carrier can no longer be detached from the base body with the support under the centrifugal forces and also the forces of the material web, but on the other hand the intermediate carrier can be removed from the base body for assembly and repair by replacing it.
  • the frictional engagement of the clamp handle acts predominantly in the longitudinal direction of the base body and prevents the reaction forces occurring in the longitudinal direction of the profile strip from displacing the intermediate carrier on the base body when the web of material spreads out.
  • the clamp handle saves additional security measures between the both parts.
  • the measures of claim 3 are advantageous.
  • the three materials in the combined composition offer the best prerequisites in terms of effectiveness.
  • the feature of claim _ is also important for the cost-effective production.
  • Such endless profile strands in particular extruded profiles, are inexpensive and can be produced to size, are easy to store and ship. Cutting the required sections to length does not require any special tools and can also be carried out directly at the location of the profile strip.
  • the shape accuracy of the modern extrusion process ensures a correct fit of the components at all times and the desired firm clamp seat, which can only be solved by arbitrary removal.
  • these two components are even made together in an extruded profile, which is useful because of the good connectivity between hard PVC and soft PVC.
  • fix the support separately on the intermediate carrier by gluing.
  • the intermediate carrier takes over the holding function for the support without being necessary for the dimensional stability and the sliding property of the profile strip during operation. For this reason, the choice of material for the intermediate carrier can be based on a connection to the support that is simple to manufacture, as strong and durable as possible.
  • the support is reduced to one or more contact strips, each of which grips the web and pulls it into the desired position.
  • the contact strip can be laid out on its free upper side only with a view to optimum grip on the material web. Since the contact strip is attached to the intermediate carrier, which is preferably made of plastic, it is not subject to the restrictions which arise when connecting elastic plastic material to a relatively hard material, for example the metallic base body. Also for critical web quality -
  • optimal grip from the profile strip to the web can be achieved, optimal grip for particularly sensitive webs also meaning a particularly gentle but effective power transmission. Because the upper side of the contact strip protrudes over the upper side of the intermediate carrier, the web of material does not have to come into contact with the free upper side of the intermediate carrier itself, so that the adhesive residues on the intermediate carrier, which were previously troublesome, no longer have a disruptive influence.
  • the additional measure of the contact strip on the one hand optimizes the grip, on the other hand the production of the profile strip or the intermediate carrier with the contact strip can be simplified. In the direction of rotation of the spreading roller, the positive connection between the contact strip and the intermediate carrier helps in the transmission of the torque.
  • the contact strip can be attached in the longitudinal groove with an adhesive that remains elastic after setting, which prevents hard adhesive contamination on the free surfaces.
  • the groove prevents glue from escaping at all. Furthermore, the groove edge provides good support for the inserted contact strip.
  • the embodiment according to claim 7 has also proven to be very suitable, in which the contact strip is formed in one piece with the intermediate carrier and holds the web so far from the free upper side of the intermediate carrier that the web with the other components does not more in contact. It is advantageous to provide the above contact strip with a surface structure. This could be done with a trailing knurled wheel during manufacture.
  • the structuring on the free upper side of the contact strip additionally increases the grip between the profile strip and the web.
  • Two different aspects can be realized. In the case of coarse and resilient webs, a positive fit can be selected in addition to the pure frictional connection. In the case of particularly sensitive web qualities, on the other hand, a particularly gentle yet frictional power transmission can be predetermined.
  • the embodiment according to claim 9 is expedient.
  • This cross-sectional shape can be realized with simple shapes. With the converging holding legs, a good fit of the profile strip in the spreading roller is achieved with always low displacement resistance.
  • the clamp grip of the legs offers a self-locking, firm fit with sufficient tolerance, which is not least achieved by the non-binding arches.
  • the legs adapt approximately to the slope of the side wall from the web.
  • the webs have an approximately prism-shaped cross section, which is very easy to master in terms of production technology.
  • the back with its convex curvature in cooperation with the straight underside of the profiled strip, ensures the desired linear support area.
  • the support area is shifted in the circumferential direction on the back of the web. This is irrelevant to the effective transfer of the spreading forces to the web; In view of the fact that the axial adjustment can always be ensured smoothly, this is a desirable effect.
  • the converging holding legs are supported on the converging flanks under centrifugal force, provided that the profile strip is not pressed in any case by the contact pressure of the material web in the linear support on the back of the web.
  • the selected cross-sectional shape is also favorable in terms of production technology, the assembly and disassembly of the profiled strips is particularly simple because they only have to be pushed on or pulled off in the axial direction.
  • the feature of claim 11 is advantageous.
  • the intermediate carrier When the intermediate carrier is pushed on, the strength of the convergence of its clamp legs is adapted to the convergence of the holding legs of the base body by elastic deformation, and the desired adjustment is achieved at the same time.
  • FIG. 3 is a perspective view of an embodiment of a profile strip without a base body
  • FIG. 1 shows a perspective view of another embodiment of a profile strip
  • FIG. 5 shows a further variant of a profile strip without a base body in a perspective view.
  • a profile strip 1 is seated on an undercut web 2 of a support ring 3 of a web spreading roller (not shown) which is approximately trapezoidal in cross section.
  • the profile strip 1 has the shape indicated in FIG. 2 in a plan view.
  • the jacket of the spreader roller is formed by a large number of closely spaced profile strips 1 which overlap with finger-like end parts 27 in the central region of the spreader roller and are pulled apart and pushed together again in the axial direction with each revolution of the spreader roller.
  • the web 29 on the spreading roller is thereby spread out. This is a common principle.
  • several support rings 3 are placed one behind the other in the spreading roller in the axial direction with aligned webs 2 in order to guide the profiled strips 1.
  • the profile strip 1 consists of an approximately C-shaped base body 4 in cross-section, and also of an intermediate support 5 pushed onto the base body 4 in the longitudinal direction with approximately the same, only somewhat wider cross-section than the base body 4, and one on an outside 13 of Intermediate carrier 4 attached, frictional and elastic pad 6.
