A faulty yarn end replacement apparatus (12) repairs faulty yarn ends (18) presented in one or more yarn carriers (16) of a weaving loom (10). The apparatus (12) comprises a maintenance unit (20) including a repair module (22), which is selectively operable to repair a faulty yarn end (18). A guide is provided to guide longitudinal movement of the maintenance unit (20) along a path of travel and a driver is drivingly connected to the maintenance unit (20) for moving the maintenance unit (20) along the path of travel. The driver is operable to move the maintenance (20) unit to a selected position along the path of travel, which may correspond to a position at which a faulty yarn end is detected by a sensor. A controller is operable to actuate the repair module (22) when the maintenance unit (20) is located in the selected position along the path of travel. The repair module may also comprise an oiling module and a cleaning module. The apparatus is preferably used with an Axminster gripper loom. Two embodiments of yarn end replacement devices are disclosed. The presence of tufts in tuft holders may be detected in order to identify empty tuft holders and yarn ends may be accordingly repaired. |
