Wire Twist Cycle

1. Initial Position of Twister

   A - Wire Gripper

   B - Wire

   The twisting cycle is as follows:

   After needle has been threaded, the end of the wire (B) is anchored by wire gripper (A). As the bale is being formed, needle wire is pulled from the wire box around the bale.

2. Catch the Wire

   A - Twister Shaft

   B - Needle

   C - Wire

   D - Twister Hook

   When the bale reaches the desired length, the measuring wheel trips the twisting mechanism. As needle (B) starts up, it catches wire (C) around the bottom of the bale and carries it up the front of the bale.

   The intermittent drive gear on the needle lift shaft engages the pinion on the bevel gear drive shaft. It turns the pinion on twister shaft (A). The needle continues to rise and places wire in shear plate notch on the opposite side of anchored wire.

   Meanwhile, twister hook (D) on twister shaft rotates clockwise. The twister hook completes one revolution and grasps both strands of wire.

3. Twist the Wire

   
   CC7828-UN-23SEP98

   A - Wire

   B - Twister Hook

   The wire gripper drive pinion engages in the intermittent drive gear. This pinion drives the gripper shaft, which actuates the arm of the gripper to release the anchored wire (A), also shearing and anchoring needle wire as gripper moves to the other side. The needle returns home and twister hook (B) makes five complete revolutions, twisting the ends of the wire together.

4. End of Twist Cycle

   
   CC7836-UN-23SEP98

   A - Anchored Wire

   B - Twisted Wire

   The finished bale pulls twisted wire (B) off the twister hook. The next bale then pulls anchored wire (A) into position for the next twisting cycle.
