Tape Spooling Device

Paper tape or film is automatically threaded onto a reel. This is by magnetically attracting a flexible armature to wrap the leading end of the tape about the reel hub.

Paper tape 1 is directed between fixed guide 2 and flexible, magnetic armature 3, such as steel shim stock, onto the hub 4 of reel 5. The latter is driven in the direction shown through a friction clutch, not shown. Hub 4 has a plurality of annular grooves 6 in each of which is wound a coil 7 connected to slip rings 8. Each coil is covered with potting compound. Coils 7 are energized through a circuit including brushes 9 connected to battery 10 and normally open contacts 11 of relay 12. Relay 12 is operated when light, shining from source 13 through holes 14 in the armature and guide onto photo-electric transducer 15, is blocked by tape 1. A transducer signal resulting from decreased light is applied to amplifier 16. This energizes relay 12 and closes contacts 11 to energize coils 7.

When coils 7 are energized, armature 3 is attracted along the broken lines 3a to hold the tape end on the hub. The continued rotation of reel 5 and feeding of tape 1 cause the tape to wind on the reel. Either relay 12 remains energized until the reel is filled or a time control circuit can be interposed between the relay and amplifier to de-energize the relay after a fixed time. As the tape accumulates on hub 4, the electromagnetic attraction of armature 3 decreases to a point where the armature i...
