Abstract
In the quilting machine the loosely superposed cover material webs and at least one filler material web, while being drawn into the quilting machine, are joined along their marginal portions by means of joining devices which are arranged laterally of the superposed webs. The web sections or selvedges lying outside the formed seams are separated and removed.
Claims9
A method of processing textile material webs, especially for the manufacture of quilts and the like in a quilting machine, comprising the steps of:
- clamping the textile material webs by means of a first clamping device disposed upstream of a tenter frame and a second clamping device disposed downstream of the tenter frame;
- for processing a workpiece;
- stretching the textile material webs between the first clamping device and the second clamping device;
- clamping the textile material webs by means of toothed segments which are laterally arranged at the tenter frame;
- stretching the textile material webs in a transverse direction relative to a predetermined direction of travel of the textile material webs by shifting first tenter means so as to rest against a stop, thus positioning the workpiece, holding the workpiece under tension by second tenter means, and subsequently closing clamping devices disposed at rear and front ends of the tenter frame and extending transversely relative to the now stretched workpiece;
- releasing the first clamping device disposed upstream of the tenter frame;
- guiding the tenter frame with the stretched workpiece to be processed towards a receiving end of the quilting machine and simultaneously withdrawing new cover material webs and at least one filler material web from a feed station;
- joining marginal portions of the textile material webs during the step of withdrawing the new cover material webs and the at least one filler material web;
- quilting the workpiece stretched in the tenter frame by means of a sewing device, thus a quilted workpiece;
- said step of quilting comprising moving the tenter frame and the sewing device relative to one another;
- and
- guiding the quilted workpiece out of the quilting machine.

- stretching the textile material webs between the first clamping device and the second clamping device;
- displacing the tenter frame into a position for engaging predetermined portions of the textile material webs for processing a workpiece;
- stretching the textile material webs located in the tenter frame in a transverse direction relative to a predetermined direction of travel of the textile material webs and holding the workpiece under tension, and subsequently closing clamping devices of the tenter frame extending transversely relative to the now stretched workpiece;
- releasing the first clamping device disposed upstream of the tenter frame;
- guiding the tenter frame with the stretched workpiece to be processed towards a receiving end of the quilting machine and simultaneously withdrawing further cover material webs and at least one filler material web from a feed station;
- joining marginal portions of the textile material webs during the step of withdrawing the further cover material webs and the at least one filler material web;
- quilting the workpiece stretched in the tenter frame to form a quilted workpiece;
- and
- removing the quilted workpiece from the quilting machine.
