Abstract
1,186,510. Automatic tension control systems. SIEMENS A.G. Feb.23, 1968 [Feb.24, 1967], No.8873/68. Heading G3R. Tape handling apparatus comprises an evacuated buffer cassette 4 between a transport roller 2 and a wind/unwindreel 6 which is driven by areversible electric motor 7 controlled by a brake 8, the members 7, 8 being in turn controlled by a device 16 receiving signals from sensing elements 9, 10, 11 which respectively produce a feed command, a stop command and a take-up command for the reel drive. Elements 9, 10, 11 divide the cassette 4 into regions 12, 13, 14, 15, the control arrangement being such that during a winding operation the loop of tape moves between the regions 13, 14, 15 and during an unwinding operation the loop moves between the regions 12, 13, 14. In the former case the brake 8 is released and the motor 7 started when the loop enters the region 15 and these actions are reversed when the loop enters the region 13, the braking action being maintained until the loop once again enters the region 15. For an unwinding operation braking occurs in the region 14 and is maintained until the loop enters the region 12, when the brake is released and the motor 7 started. In switching between wind and unwind operations, depending on the position of the tape, the wind or unwind process continues or the reel is held stationary until the loop enters the region 12 or 15. Thus operation of the system is not affected by transient changes in the direction of tape movement. Apart from the brake 8, which may be of permanent magnet type, the nature of members 9, 10, 11, 16 and 7 is not disclosed.
