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.
