Tubular cop exchange arrangement for looms
摘要:
A tubular cop exchange arrangement comprises a cop magazine, a cop pressing device for pressing a cop from the magazine into a trough chamber of a shuttle, a cutting device for separating a weft thread from the ejected remaining portion of the cop and a control device. The shuttle has a clamping device provided near one end of a trough chamber for fixing the holding pin of a tubular cop, the shuttle having a thread brake and a thread inserting slot extending from another end of the trough chamber substantially rectilinearly. The cop ejecting device has a cop ejecting plunger which is upwardly extendable in a shuttle cop exchange position in a direction toward the holding pin clamped in the clamping device. The cop pressing device has a cop pressing plunger which is extendable in the cop exchange position downwardly against a cop located in the cop outlet opening of the cop magazine. In the cop exchange position the thread inserting device is positioned over the thread inserting slot and is lowerable simultaneously with the cop pressing plunger for insertion of a weft thread into the thread inserting slot. The thread inserting device is provided with at least one thread gripper, advantageously two thread grippers.
