Abstract

Drawings A and B show similar tape strips handling devices. In A, strips 1 are supported in the form of loops in cartridges 2. In B, the strips are wound on spools 27 in cartridges 2. In each case, the outer end of each strip has a piston 15. The latter is formed by bending the end of the strip backwardly onto itself and fastening it by tape or cement. The opposite end of each strip is fastened to a cartridge 2 at 12 in A or to a spool 27 in B. Cartridges 2 can be manually replaceable.

Tape Strip Library

Drawings A and B show similar tape strips handling devices. In A, strips 1 are supported in the form of loops in cartridges 2. In B, the strips are wound on spools 27 in cartridges 2. In each case, the outer end of each strip has a piston
15. The latter is formed by bending the end of the strip backwardly onto itself and fastening it by tape or cement. The opposite end of each strip is fastened to a cartridge 2 at 12 in A or to a spool 27 in B. Cartridges 2 can be manually replaceable.

In each drawing, any strip is accessed by pivoting upwardly a door 5 above the strip to be selected. Vacuum applied to port 4 is communicated to the selected piston 15 through vacuum column 11, tube 18, and chamber 17 to piston 15 within cartridge 2 having the raised door 5. Atmospheric pressure is provided at this time within the cartridges by dropping door 6 in drawing A to block off the vacuum source to the cartridges and permit entry of atmospheric pressure therein. The selected piston 15 is drawn along a path over capstan 13 into chamber 7. It is stopped at the bottom of chamber 7 at its entrance to tube 18 by the smallness of the opening or by a screen, not shown, across it. Then solenoid 10 is actuated and it pivotally moves door valves 8 and 9 to vertical positions, thus permitting the strip to be threaded into vacuum columns 11 and 12, forming loops in the strip. The threading can use loop positions sensors 21 provided in the vacuum columns to sense the positions of th...
