Abstract
A withdrawing carrier for looms with removal of the filling thread from stationary bobbins, the carrier having a hook and a pivotal clamping tongue. An additional clamping element is provided for augmenting the clamping action exerted by the clamping tongue upon the filling thread.
Claims10
A withdrawing carrier for looms with removal of the filling thread from stationary bobbins comprising:
- means providing a gripper body for the withdrawing carrier,
- a hook having a hook mouth for receiving a filling thread to be engaged and provided for said gripper body;
- a pivotable clamping tongue cooperating with said hook for exerting a clamping action upon a filling thread located in said hook mouth;
- an additional clamping element for augmenting the clamping action exerted by said clamping tongue;
- and
- said additional clamping element comprising a clamping spring extending essentially in the lengthwise direction of the gripper body.
