Rubberized composed of a series of sections

Panel of fabric

The invention relates to a chewed skin made of a Sequence of sections composed of a web of fabric whose yarns, threads or cords are more or less transverse to the cut or Longitudinal direction of the sections lie.

Will be butt on abutment or overlapping successive sections the aforementioned rubberized material webs conveyed from the place of their manufacture to the place of their processing, then they go through compensation loops in which they are subjected to a more or less large longitudinal pull, whereby the width of the sections or the sequence of sections is not aimed at, undergoes harmful changes.

The invention is based on the object of avoiding this disadvantage. This object is achieved according to the invention by in Longitudinal direction of the sections or the sequence of sections firmly adhering to these laid-on yarns, threads or cords. By a Such a design of the sections or sequence of sections, it is possible to chew the width and length of the width and length of chewed material webs to produce without a fabric having to be used for this purpose. The sections or sequence of sections to be processed Rubberized webs of fabric, for example, only need to be made from yarns, twisted threads or cords that run parallel to one another

consist, which are connected to each other by the rubber coating are. But not only when processing webs of fabric that are enclosed in them and run parallel to one another Yarns, twisted threads or cords are a major advantage achieved but also when these rubberized material webs contain some kind of fabric. Because around sections or To achieve section sequences in the invention To be true to size, a fabric produced on special weaving machines would have to be used, which would be very expensive. Through the firmly adhering laying of yarns, twisted threads or cords in the longitudinal direction on the sections or section sequences on the other hand, production is cheaper by at least half of the previous costs. Will - as it is general It is customary - the sections of the rubberized material webs are not chosen to run perpendicular to them but to run at an angle, then another feature of the invention will gladly overlap Yarn, twisted or cord parts, i.e. triangular connection shapes, of the sections or sections then follow achieved when these are folded around their central axis after being covered with longitudinal yarns, twisted threads or cords.

In the drawing, an embodiment of the invention is shown in outline.

A warp thread web or a fabric (2) is wound onto a warp beam (1). The warp thread path (2) or the like revolves around a pulley (15) and is fed to a calender (4). If the warp thread path or the like only contains warp thread, it will run through shortly before add a comb to the calender (j?). In the calender (4) is the Warp thread web (2) or the like with a rubber mixture (16) like this

coated so that the rubber mixture also enters between the individual threads. The on this V / else resulting kautschukierte Kettfadenbahn (5) or. The like. Is advanced by a conveyor (6) and passes it in the region of a cutting unit (7) 's the compartments obliquely to Kettfadenbahn (5) lying portions (8) mediated by this.

The warp thread path sections (8) or the like come to lie on an inclined table (13), where they are connected to the preceding sections by butt or overlapping connections. The connection of successive sections (8) achieved in this way can be achieved by suitable. Pressing, technical means are improved. The sequence of sections (9) formed by joining the sections (8) passes under a deflection roller (10) tangentially to this. Yarns, threads or cords (11) made of known natural, synthetic or synthetic fibers or mixtures thereof are fed from bobbins (12) to the section sequence (9) via this deflecting roller (10) and then through from the deflecting roller (10) applied pressure applied adhesive. The thus reinforced by the yarns, threads or cords (11) in the longitudinal direction portion of sequence (9) passes from the support (13) ^au f a known memory device which allows a further processing of the portion of sequence (9) with interruptions.

Behind the storage system, the sequence of sections (9) can be one Longitudinal axis are folded, so that in general a triangular association of the deposits of the sequence of sections (9) is formed, which the Dimensional accuracy of the sequence of sections (9) also before the further processing Assembly (e.g. into hoses) and vulcanization guaranteed in every direction.
