LOOM WARP REGULATOR Russian patent published in 1994 - IPC

FIELD: textile industry. SUBSTANCE: as warp threads tension in loom warp regulator increases, three-arm lever 4 is turning counter clockwise, pulling 6 at the time goes up and turns two-arm lever 10 and link 7 clock-wise. Groove 8 form and stationary stone 9 make two-arm lever 11 to turn counter clockwise, that causes increase of time of contact of roller 13 with disk cam 14 and increase of weaver's beam 17 turning angle clockwise, that increases amount of warp threads feeding. In case of warp threads tension loosens operation of the warp regulator is exercised in reverse order. As beam 17 wears off, feeler 18 turns counter clockwise and through pulling 27 turns link 21 relatively point 28. Groove 22 of link 21 is made in the form of exponential curve, corresponding to the rule of warp treads tension change in compliance with process of the beam wearing off. So during link 21 rotation clockwise two-arm lever 25 turns counter clockwise, transporting hinge 26 and two-arm lever 11 counter clockwise , that increases time of contact of roller 13 with dick cam 14 and amount of warp threads feeding from the beam. EFFECT: regulator is used in textile industry. 1 dwg
