Abstract

In un nastro per il trasporto di pinze portatrama nel passo dei telai di tessitura, del tipo flessibile avente fori quadrangolari allineati lungo il proprio asse, con cui si impegnano i denti della ruota dentata di azionamento, detti fori hanno sezione longitudinale rastremata coi profili delle facce trasversali del foro inclinati convergenti. Tale nastro viene prodotto con un procedimento che comprende le fasi di: a) praticare nel nastro fori quadrangolari di dimensioni ridotte per tranciatura; b) impartire mediante brocciatura ad una delle facce trasversali di detti fori un profilo inclinato convergente rispetto a quello dell'altra faccia; e c) impartire mediante brocciatura all'altra faccia trasversale del foro un profilo inclinato convergente rispetto a quello della prima faccia.In a belt for the transport of weft grippers in the pitch of the weaving looms, of the flexible type having quadrangular holes aligned along its own axis, with which the teeth of the driving gear wheel engage, said holes have a longitudinal section tapered with the profiles of the faces inclined transverse holes of the hole. This tape is produced with a process which includes the steps of: a) drilling rectangular holes of small dimensions by punching; b) imparting by an broaching to one of the transverse faces of said holes an inclined profile convergent with respect to that of the other face; and c) by broaching to the other transverse face of the hole an inclined profile convergent with respect to that of the first face.
