20080216726 | Method and apparatus for producing a sewn product - The present invention relates to a method for producing a sewn product, especially a mattress panel, a quilt or the like, having corner areas which deviate from an orthogonal pattern, preferably from several layers of sewn product material which are to be stitched together, as a segment of a sewn product material, 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, by means of a sewing device which is movable transversely to the conveying direction of the sewn product material, and in which the sewn product material is subsequently cut between the two stitched seams, wherein the sewing device includes a sewing unit with needles and an oscillating shuttle box including shuttles which are assigned to the needles, in order to produce in a simple and inexpensive way sewn products having corner areas which deviate from an orthogonal pattern, wherein with a device at least one sub-area of a transition area of adjacent sewn products arranged in the conveying direction of the sewn product material is removed, said removal of said sub-area covering both sewn products that are arranged adjacent to each in the sewn product material and being performed prior to or during the stitching of the seams transversely to the conveying direction. | 09-11-2008 |
20080271658 | Sewing Machine and Sewing Element - This invention relates to a sewing machine, in particular a chain stitch or a double chain stitch sewing machine and preferably a multiple needle chain stitch or a multiple needle double chain stitch sewing machine employing three stitch forming sewing elements, namely a needle, a looper, and a spreader, with said spreader spreading a thread triangle of a looper thread in which the needle carrying a needle thread plunges for the connection of the needle thread to the looper thread, and with said sewing elements being driven through at least one driving means. The invention further relates to a sewing element for a sewing machine, in particular a chain stitch or a double chain stitch sewing machine, preferably a multiple needle chain stitch or a multiple needle double chain stitch sewing machine, said element consisting of a spreader that spreads a thread triangle of a looper thread in which a needle carrying a needle thread plunges for the connection of the needle thread to the looper thread. For further improving a sewing machine or a sewing element of the above-mentioned type in such a way that a collision of the sewing elements of the sewing machine will not cause any serious damage to the sewing machine and stop periods as a consequence thereof, it is provided that the sewing elements are formed such that at least one sewing element, in particular the spreader, will dodge or break at a predetermined breaking point in the case of a collision with a second sewing element, in particular the needle, due to its design and/or material properties. | 11-06-2008 |
