Abstract
Pinza portante per telai di tessitura senza navetta le cui parti componenti non presentano accoppiamenti mobili a cerniera o a slitta che richiedano la presenza di giochi meccanici. La pinza presenta quindi un'elevata resistenza all'usura.L'organo di ritegno mobile della pinza è formato da una lamella flessibile (6) vincolata con un suo estremo (6b) al corpo della pinza, e mantenuta premuta contro un organo di ritegno fisso (5) da mezzi a molla a balestra (8) che agiscono sulla sua estremità libera (6a). Sono previsti mezzi di regolazione (12-14) per variare la intensità del carico della molla a balestra (8) sull'organo di ritegno mobile (6).All'organo di ritegno mobile (6) è vincolata una leva rigida (10), azionabile da una camma del telaio, per aprire la zona di ritegno della pinza mediante il sollevamento elastico dell'organo di ritegno mobile (6) e consentirne la pulizia.Supporting gripper for weaving looms without shuttle whose component parts do not have movable hinged or sliding couplings which require the presence of mechanical clearances. The gripper therefore exhibits high wear resistance.The movable retention member of the gripper is formed by a flexible blade (6) secured with one of its ends (6b) to the gripper body, and kept pressed against a retention member fixed (5) by leaf spring means (8) which act on its free end (6a). Adjusting means (12-14) are provided to vary the load intensity of the leaf spring (8) on the movable retaining member (6). A rigid lever (10) is attached to the movable retaining member (6). , operated by a cam on the frame, to open the retention area of the gripper by means of the elastic lifting of the mobile retention member (6) and to allow its cleaning.
