CA 2329082

An improved quick-change winding form assembly in which the support is divided into two parts, one part comprising a bearing collar (12), being connected to a bearing at the front of the flier assembly, and the other part comprising a mounting plate (18) connected to the winding form or shroud. A pair of bayonet pins (10) having enlarged heads (13) is carried by the bearing collar (12) and engages a pair of arcuate key slots (16) extending through the mounting plate (18). The bayonnet pins (10) engage the arcuate key slots (16) when the bearing collar (12) is rotated relative to the mounting plate (18) until a pair of spring biased balls (28) mounted on the bearing collar (12) enters recesses in the rear face of the mounting plate. Disassembly can be accomplished by simply rotating the winding form with its attached mounting plate in the opposite direction while holding the bearing collar fixed.

L'invention concerne un ensemble de forme d'enroulement à modification rapide dont le support est divisé en deux parties, l'une comprenant une bague d'appui (12) connectée à un appui au niveau de la partie avant de l'ailette et l'autre partie comprenant une plaque de montage (18) reliée à la forme d'enroulement ou chemise. Une paire d'ergots (10) présentant des têtes élargies (13) de fentes arquées s'étendant à travers la plaque de montage (18) entre en contact avec les deux fentes arquées (16). Les ergots (10) s'engagent dans les fentes (16) lorsque la bague d'appui tourne par rapport à la plaque de montage jusqu'à ce qu'une paire de billes sollicitées par un ressort montées sur la bague d'appui (12) s'engagent dans des évidements (28) ménagés dans la face arrière de la plaque de montage. On peut désassembler cet ensemble par simple rotation de la forme d'enroulement avec sa plaque de montage fixée dans le sens opposé tout en maintenant la bague d'appui fixe.
