Automatic Threading Apparatus

This apparatus is for automatic threading of strip material or tape on a hub or reel. The threader finger consists of head 2 mounted on spring lever 4 which is, in turn, secured to pivot mounting 6. Tube 8 connects head 2 to a vacuum- blower source not shown.

In operation, the leading edge of strip 12 is manually associated with and held by head 2 while it is operating in a vacuum mode at position A. The threader finger is then pivoted through an arc to position B in proximity to stationary winding or reel hub 14. Blowing pressure is then applied through tube 8 to head 2. Such action positively releases strip 12 and places it in contact with hub 14. The finger is then swung back to position A and winding of the hub is begun. Before bringing a strip 12 into contact with the hub, the end of the strip can be wetted, for example, with water, in order to improve its initial adhesion to the hub.

When the hub or reel is fully wound, its rotational motion is stopped and the finger is pivoted to position C with head 2 operating in a vacuum mode. Suction at head 2 positively grasps the outer wound layer. The latter is then lifted away from the hub by pivoting the finger back to position A. At this time, the portion of strip 12 between head 2 and the wound hub is severed by blade 16, with head 2 continuing to hold a lead end of the tape. The fully wound hub is then indexed away from the threading apparatus and a new hub is positioned for windin...
