Abstract
The invention relates to a device for the winding of a knitted material web which is being delivered from a warp knitting machine to a material roll by using an axial drive which is being regulated by sensors which measure the tension in the material web. For the purpose of winding a knitted elastic material, a spreader roller is arranged adjacent to the run-on site of the web onto the material roll and is held there with a constant gap. In order to maintain an essentially constant gap between the spreader roller and the material roll, the spreader roller undergoes a relative shifting along a radial guide.
Claims7
Device for winding up a knitted material web which is being delivered from a warp knitting machine to a material roll by way of a shaft drive.
- wherein the rotational speed of the shaft drive is regulated in response to a sensor which senses the tension of the material web;
- and wherein spreader roller is arranged adjacent to the material roll and maintained an approximately constant distance from the material roll by shifting the spreader roller along a radial guide;
- and wherein the spreader roller is driven by a drive means such that the spreader roller maintains a rotational speed which substantially exceeds the delivery speed of the web.
