Sewing system for the overlapping sewing of an elastic facing to the edge of a knitted article

摘要

In a sewing system according to the invention for the overlapping sewing of an elastic facing to the edge of a knitted article, for example to the cutout of an article of clothing two endless conveyor bands lie parallel to one another on both sides of the seam line and equipped with means of adhesion are arranged on a feed table, for the purpose of the fixed reception of the facing or article, with a guide located in front of the needle region and intended for the edge of the article. In order to make it possible to process in a high-quality manner knitted articles curling sharply at the edges, without any finishing treatment, a web screening off the article conveyor band on the narrow side directed towards the other conveyor band is provided in front of the needle region. Furthermore, there is provided an approximately U-shaped or V-shaped double spring-wire yoke which is directed obliquely relative to the running direction of the article edge and which engages resiliently with the free leg of its obtusely angled end portion into a recess provided on the needle region in the web. In such a sewing system, the article edge curling up or in is first guided freely, but in a way screened off from the means of adhesion of the article conveyor band, to the uncurling device just in front of the needle region. The uncurling device according to the invention makes it possible to flatten both a curling-up and a curling-in article edge.
