Abstract
The present invention relates to a simple and inexpensive method for producing a mattress panel or quilt having corners which deviate from an orthogonal pattern. The method renders a material having two stitched seams between two sewn products that are arranged adjacently. The two stitched seams are created by a sewing device, which moves transversely to the conveying direction of the material. The material is cut between said seams by a sewing unit, located within the sewing device. Prior to or during the stitching of the seams, another device removes a sub-area comprising both sewn products, resulting in a mattress panel or quilt with corners deviating from an orthogonal pattern.
Claims32
A method for producing a mattress panel or a quilt having corner areas which deviate from an orthogonal pattern, the mattress panel or quilt having several layers of sewn product material stitched together, in which method the sewn product material is provided with at least two stitched seams between two sewn products that are arranged adjacent to each other in the sewn product material, the method comprising sewing the at least two stitched seams between the two sewn products by moving a sewing device transversely to the conveying direction of the sewn product material, cutting the sewn product material between the two stitched seams, wherein the sewing device includes a sewing unit with needles and a shuttle box including shuttles which are assigned to the needles, and removing, prior to or during the stitching of the seams, at least one sub-area of a transition area of adjacent sewn products arranged in the conveying direction of the sewn product material wherein the removal of the sub-area covers both sewn products that are adjacently arranged in the sewn product material.
A multiple needle sewing machine for producing a mattress panel or a quilt, having corner areas which deviate from an orthogonal pattern, from several layers of sewn product material which are to be stitched together, as a segment of a product material, said multiple needle sewing machine comprising a sewing device which is movable transversely to the conveying direction of the product material and which includes a sewing unit with needles and a shuttle box with shuffles assigned to the needles, and a device, by which at least one sub-area is removed from at least two sewn products adjacently arranged in the conveying direction of two product materials.
