ROLL LEVER FOR POSITIVE HEALD MOTION TO DRIVE THE HEALD FRAMES OF LOOMS

摘要

Levers with double roller assemblies for positive cam mechanisms for controlling the heddle frames of weaving looms wherein each roller assembly comprises a rotating ring supported on a plurality of roller bearings retained relative thereto on a fixed support mounted to or on extension of the levers. The rings and supports are thus capable of penetrating between the cams of the weaving loom without modifying the axial dimensions of an assembly of such cams.
