Process for assembling the actuation elements of a rotating dobby

Claim 1

A process for assembling the actuation elements of a rotating dobby wherein each element includes a driver plate which is adapted to be mounted on an intermittently driven principal drive shaft and which is selectively connected by a first engaging means controlled by a reading device to an eccentric which is mounted on a bearing means to the principal drive shaft and which is also selectively connected to a connecting rod by way of a second engaging means and wherein the connecting rod is coupled through a drawing lever to a heddle frame in a weaving loom, said process comprising the steps of: a) mutually positioning each of the actuation elements on the principal drive shaft and engaging each first engaging means with its corresponding driver plate and engaging each second engaging means with its corresponding eccentric; b) aligning the actuation elements on the principal drive shaft in side-by-side relationship by pivotally connecting each connecting rod with a drawing lever which extends between each connecting rod and its corresponding heddle frame; and c) exerting an axial tightening force along the principal drive shaft, thereby gripping the driver plates between the bearing means and securing the driver plates to the principal drive shaft while allowing the eccentrics to be rotatable with respect to the principal drive shaft.
