Abstract
An apparatus for forming a loop in a filament comprising a first wall having a first guide slot formed therein and a second wall having a second guide slot formed therein coplanar and parallel to the first guide slot. The first wall is opposite the second wall and each of the guide slots has opposing ends. A first gripper holds a filament at a first location. The first gripper is mounted from the first wall to the second wall at an end of each of the first guide slot and the second guide slot. The apparatus also includes a movable gripper to hold the filament at a second location. The movable gripper has a separation from the first gripper and is mounted from the first wall to the second wall adjacent to the other end of each of the first guide slot and the second guide slot for movement towards the first gripper to reduce the separation between them. This produces a loop of filament between the first gripper and the moveable gripper.
