Abstract

This apparatus provides for automatic threading of strip material or tape on a reel. The apparatus is mounted adjacent a reel winding station. It consists of one or more curved arms 2. The latter are mounted on pivot pins 4 and capable of being rotated between the flanges of reel 6, shown with the top flange removed, to bring their curved inner faces into proximity with the winding surface of reel hub 8. Arms 2 are internally channeled, to allow for the passage of air, with the internal channels terminating in a number of ports 10. The channels within arms 2 are connected to a source of air pressure.

Reel Loading Mechanism

This apparatus provides for automatic threading of strip material or tape on a reel. The apparatus is mounted adjacent a reel winding station. It consists of one or more curved arms 2. The latter are mounted on pivot pins 4 and capable of being rotated between the flanges of reel 6, shown with the top flange removed, to bring their curved inner faces into proximity with the winding surface of reel hub 8. Arms 2 are internally channeled, to allow for the passage of air, with the internal channels terminating in a number of ports 10. The channels within arms 2 are connected to a source of air pressure.

In operation, tape 12 is fed into the vicinity of hub 8. Arms 2 are pivoted into proximity with hub 8 and air pressure to the arm channels is initiated, with resulting air jets issuing from ports 10. Once tape 12 is in the space between ports 10 and hub 8, it is propagated by air jets from ports 10. The latter are angled to create a driving force on tape 12 which causes it to move around hub
8. While moving tape 12, the same air pressure causes a Bernoulli force. This has a lifting effect on tape 12, thus holding it up and away from hub 8.

If electrostatic attraction exists between the tape and the hub material, loading can be obtained with a single curved arm 2. If no such electrostatic attraction exists, a second arm 2, as shown, continues to propagate the tape around the hub until it is secured beneath a portion of incoming tape. Once thread...
