US 5,040,473 A · Method of, and apparatus for, processing textile material webs, particularly for manufacturing quilts and the like

Abstract

In a quilting machine for quilting or stitching textile formations of cover-material webs and filler-material webs, the material webs to be stitched together are loosely withdrawn from stock rollers and sewn together along lengthwise edges or marginal portions of the material webs prior to entering a tenter device. Sewing the lengthwise edges or marginal portions includes simultaneously sewing on respective bands or ribbons which laterally extend beyond a workpiece to be quilted and serve for holding or accommodating the latter in the tenter device. It is thus possible to substantially provide the entire width of the cover-material webs and filler-material webs with a quilt pattern. In this manner, the length of waste cuttings of expensive cover material is substantially reduced.

Dependent claims

A method of processing textile material webs in a quilting machine, comprising the steps of:

withdrawing cover-material webs and filler-material webs from a material stock;
laterally sewing together the cover-material webs and the filler-material webs along lateral lengthwise edges thereof;
during said step of laterally sewing together the cover-material webs and the filler-material webs, sewing on a band laterally extending beyond the lateral lengthwise edges of the joined cover-material webs and the filler-material webs;
clamping and stretching section-by-section in a tenter frame the cover-material webs and the filler-material webs sewn together with the bands laterally extending beyond the lateral lengthwise edges and thus forming a workpiece;
quilting the cover-material webs and the filler-material webs of the workpiece in the tenter frame;
and
guiding the quilted workpiece out of the quilting machine.

4 more elements

An apparatus for processing textile material webs, comprising:

a feed station provided with a stock of textile material webs including cover-material webs and filler-material webs;
means for withdrawing said cover-material webs and filler-material webs from said stock of textile material webs to form superposed cover-material webs and filler-material webs having lateral lengthwise edges, said superposed cover-material webs and filler-material webs forming a workpiece;
a sewing device comprising at least one sewing head;
a tenter frame guidable back-and-forth relative to said sewing device and wherein said workpiece of said superposed cover-material webs and filler-material webs is stretched;
said superposed cover-material webs and filler-material webs having a predetermined path of conveyance;
means for providing each of said lateral lengthwise edges with a band extending laterally beyond the associated lateral lengthwise edge;
said sewing device including sewing machines arranged between said feed station and said tenter frame and provided at each lateral side of said predetermined path of conveyance of said workpiece of said superposed cover-material webs and filler-material webs;
and
said sewing machines serving to join respective lateral lengthwise edges of said superposed cover-material webs and filler-material webs and to sew on said bands extending beyond said respective lateral lengthwise edges to form seams.
