Device and method for treating (softening) continuously conveyed material

摘要

A device for treating a continuously conveyed thread group in order to produce tire cord has a roller pair for locally softening the thread group, wherein each roller (3, 4) is provided with a toothing formation. When the thread group is guided through between the rollers (3, 4), it is deformed by the mechanical loading of the teeth. The rollers (3, 4) can be driven in a separate manner directly or indirectly by way of actuable electric motors, as a result of which the gap spacings (A) and (B) can be set precisely identically. The axle spacing (C) of the two rollers (3, 4) can be set depending on the fabric thickness and the fabric type.

主权项

1. A device for treating continuously conveyed material, comprising at least one unit for deforming the material,
said at least one unit containing a pair of rollers, each roller of said pair of rollers being provided, in each case, with an exterior profiling designed to deform the material by a mechanical action of the profiling, each roller of said pair of rollers being operatively connected to one another in such a way that, when said material is feed through between said pair of rollers, the material being deformed by the mechanical action of the profiling of the pair of roller; wherein each roller of said pair of rollers is driven separately, and each roller of said pair of rollers is assigned a rotary drive, said rotary drives of each roller of said pair of rollers separately controllable by control means, said control means have a controller for regulating an angular position and/or angular speed (ω1,ω2) of each roller of said pair of rollers; the pair of rollers each comprise a toothed roller and including sensors which detect gap widths (A, B) occurring between respective flank portions of the pair of toothed rollers, said sensors are operatively connected to the control means, said rotary drives are controlled separately by said control means such that the gap widths (A, B) are equated to one another; and additionally, a second deforming unit with a pair of rollers and third deforming unit with a knife edge, and said knife edge runs transversely to a direction of the material.
