Description

A seam arrangement for connecting the two ends of a fabric so as to form an endless belt, particularly for use in papermaking. The seam arrangement comprises two endless coils (10) which are respectively located at the free ends of the fabric and on interdigitation are brought into union by a pintle wire. Each loop of the coils (10) is secured to the fabric by a "short" fabric loop (22) and a "long" fabric loop (18). The short fabric loop is located at the right hand side of the long fabric loop when looking up the fabric towards the seam.

On décrit un dispositif de couture qui permet d'assembler deux bords d'un tissu de manière à former une bande sans fin, notamment pour une utilisation en papeterie. Le dispositif de couture comprend deux spirales sans fin (10) disposées aux extrémités libres du tissu, respectivement, et qui, au point d'entrelacement, sont assemblées par un fil charnière. Chaque boucle des spirales (10) est fixée au tissu par une boucle de tissu "courte" (22) et une boucle de tissu "longue" (18). La boucle de tissu courte est placée sur le côté droit de la boucle de tissu "longue" lorsqu'on examine le tissu vers la couture.
