Abstract
A device for producing a roller blind web of a motor vehicle, the device having an application table having a continuously flat support surface for a fabric; and an extruder configured to apply a plastic material to the fabric from above along at least one extrusion track. A tensioner tensions the fabric in the direction of the extrusion track. Moreover, a method for producing a roller blind web is provided.
Claims10
A device for producing a roller blind web of a motor vehicle, the device comprising:
- an application table having a flat support surface for a fabric;
- and an extruder configured to apply a plastic material to the fabric from above along at least one extrusion track, the device having a tensioner for tensioning the fabric in a direction following the extrusion track;
- wherein the tensioner comprises a tensioning frame which at least partially limits the fabric at its edges;
- and
- wherein the tensioning frame comprises a base frame and tensioning elements engaging the fabric in a force-fitting manner.

A method for producing a roller blind web of a motor vehicle, the method comprising the steps of:
- placing a fabric on an application table, the fabric lying flat;
- tensioning the fabric by a tensioner disposed at the application table;
- applying a plastic material to the fabric along an extrusion track extending at least essentially in the tensioning direction defined by the tensioner;
- and releasing the tension of the fabric applied by the tensioner, and
- wherein the fabric is tensioned in the longitudinal direction and then provided with the plastic material along a first extrusion track, which runs in the longitudinal direction, and the tension running in the longitudinal direction is subsequently released, whereupon the fabric is tensioned in the transverse direction and provided with the plastic material along a second extrusion track, which runs in the transverse direction.
