Abstract
A mechanism for a gripper Axminster loom is disclosed which includes a plurality of yarn carriers each of which is movable to any one of a plurality of predetermined positions. Each carrier guides a plurality of tuft yarn and is arranged to present one of the yarns to a gripper when the carrier is located at a corresponding one of the predetermined positions. The mechanism includes a plurality of independently controllable rotary drive motors, each of which is connected to drive an associated carrier for selectively moving the associated carrier to a selected one of the predetermined positions.
Claims11
A gripper Axminster loom including a tuft yarn selection mechanism, the mechanism including:
- (a) a plurality of tuft yarn carriers each of which is moveable to any one of a plurality of predetermined positions;
- (b) each carrier having a plurality of yarn guides which are spaced from one another for guiding a plurality of tuft yarns and being arranged to present a selected one of said yarns into registry with a gripper when the carrier is located at a corresponding one of said predetermined positions;
- (c) a plurality of independently controllable rotary drive motors, each drive motor being drivingly connected to an associated carrier to cause movement of said associated carrier;
- and
- (d) an electronic control system operable to selectively operate each motor to move an associated carrier to a selected one of said predetermined positions and operate said motor to temporarily hold said associated carrier at said selected one position.
