Method and apparatus for manufacturing a sewing product

Abstract

The present invention relates to a method for manufacturing a sewing product (20,21), particularly a mattress panel, a quilt or the like, preferably from several sewing product layers that are to be stitched together, as a section of a sewing product material (11), in which method said sewing product material (11) is, by means of a sewing device (1) that is movable transversely to the conveying direction, provided with at least two stitched seams (19) between two sewing products (20, 21) which are arranged adjacent to each other in the sewing product material (11), and in which the sewing product material is subsequently cut between these two stitched seams (19), said sewing device (1) including a sewing unit (3) with needles (18) and a gripper box (8) with grippers allocated to said needles (18), and a tape-like sewing element (14) being sewed to the sewing product material (11) in the area of the stitched seams (19). The invention further relates to an apparatus (2) for manufacturing a sewing product (20, 21), in particular a mattress panel, a quilt or the like, preferably from several sewing product layers that are to be stitched together, as a section of a sewing product material (11), which apparatus comprises a conveyor mechanism for conveying the sewing product material (11), a sewing device (1) consisting of a sewing unit (3) with at least two needles (18) and a gripper box (8) with at least two grippers allocated to the respective needles (18), a cutting mechanism (4) for separating a sewing product (20, 21) from the sewing product material (11) after the sewing of two stitched seams (19) transversely to the conveying direction of the sewing product material (11) by a cut between the stitched seams (19), and a storage mechanism (13) for a tape-like sewing element (14) which may be stitched to the sewing product material (11) in the area of the stitched seams (19). For further improving a method of the above-described type in such a way that corresponding inaccuracies and their subsequent treatment can be avoided by the sewing product material (11) being cut and sewed-up on the rim, without tensions occurring in the sewing product material (11), it is proposed with the present invention that a sewing unit (3) is guided during the sewing of the stitched seams (19) along a first guide means and the gripper box (8) is guided along a second guide means, and that the movements of the sewing unit (3) and the gripper box (8) are synchronized with each other.
