DEVICE FOR REGULATING SHRINKAGE OF THE WARP AT LOOM Russian patent published in 1995 - IPC

FIELD: textile industry. SUBSTANCE: device has worn warp length pickup 1, ready tissue length transducer 2 and main shaft rotation frequency pickup 3. All units mentioned are connected to unit 4 for calculating rate of motion of the warp and ready tissue. Device also has shrinkage set-point device 5, unit 6 for calculating shrinkage of the warp, digital-to-analog converter 7, unit 8 for controlling rotational frequency of warp beam, actuating engine 9, reducer 10, warp beams tension gauge 11, analog-to-digital converter 15, tension set-point device 13, loom 14. Anchor 16 of the tension gauge is connected kinematically with movable unit 17 of the loom. Warp threads being wound onto warp beams 18, bend about motionless unit 17. Warp beams are collected into droppers 20 and holders 21. Breast beam 22, doffer 15, roller 23 and bar 24 serve as guides for moving tissue. EFFECT: improved efficiency. 1 dwg
