Pneumatic positioner for the displacement of needles, punches, yarn guides and sinkers for application on textile machines and cotton looms

摘要

This invention concerns a pneumatic mechanical device for installation on textile machines and cotton looms, and consists of a niche-type structure where the seats for the cylinders and toothed vices are obtained. The structure of the positioner moves on a linear toothed guide with the same pitch as the vices. Thereby giving a precise sequence (electronically controlled) of action to the locking vice, to the sinker vice and the moving cylinders; the positioner then takes itself to the predetermined desired position. This is destined for the connection of the punches, yarn guides and needles; in such a way as to allow the weaving machines to work complex knits. IMAGE
