The return spring for a smooth job a jacquard loom relates to a mechanical.

摘要

This sprung return element is of the type including a coil spring (5) which is anchored, at each of its ends (5a, 5b), on a threaded end-fitting (4, 6) generally made of moulded or injection-moulded plastic, one (4) of which is overmoulded over the lower end of the metal wire of the heald (1) and the other (6) extends up to the clamp, allowing it to be anchored to the fixed member of the weaving loom. The clamp (7) is slightly curved by virtue of the formation of an eyelet, the diameter of which may be variable depending on adaptation to vibrations. This eyelet may also be covered by a viscoelastic material. IMAGE
