Abstract

L'invenzione riguarda un gruppo di stiro con sbarrette ad aghi, con sbarrette ad aghi munite di perni di supporto e perni di biella, le quali sono disposte a distanza di ripartizione in un percorso senza fine chiuso su se stesso, guidate ed azionate mediante cinghie dentate attraverso un trascinatore per ogni perno di supporto. Allo scopo di accrescere la silenziosità di funzionamento e la durata di vita del mezzo azionatore, viene proposto che la cinghia dentata che aziona i perni (12) di supporto abbia sul suo lato esterno una dentatura il cui passo corrisponda al passo delle sbarrette ad aghi e che il trascinatore per l'accoppiamento dei perni di supporto con la cinghia dentata presenti un profilo dentato che si adatta nella dentatura esterna della cinghia dentata, un cuscinetto per i perni di supporto in vicinanza e all'interno dei contorni esterni del profilo dei denti ed una superficie di guida su un settore del percorso di guida disposto parallelamente alla guida della cinghia dentata, preferibilmente spostabile in senso trasversale rispetto alla direzione di circolazione.The invention relates to an ironing group with needle bars, with needle bars equipped with support pins and connecting rod pins, which are arranged at a distribution distance in an endless path closed in on itself, guided and operated by belts toothed through a driver for each support pin. In order to increase the silent operation and the life span of the actuator means, it is proposed that the toothed belt which drives the support pins (12) has on its external side a toothing whose pitch corresponds to the pitch of the needle bars and that the driver for coupling the support pins with the toothed belt has a toothed profile that fits into the external toothing of the toothed belt, a bearing for the support pins in the vicinity and inside the external contours of the tooth profile and a guide surface on a sector of the guide path arranged parallel to the guide of the toothed belt, preferably movable transversely with respect to the direction of circulation.
