1486153 Looms ELITEX-ZAVODY TEXTILNIHO STROJIRENSTVI GENERALNI REDITELSTVI 7 Aug 1975 [12 Aug 1974] 33051/75 Heading D1E Hydraulic liquid from outlet 20 of a hydraulic motor 13 driving a warp beam 11, passes via a valve 22 to inlet 25 of a hydraulic motor 10 driving a take-up roller 1. Valve 22 throttles the flow according to the tension of warp 12, thus controlling the back pressure and hence the speed of motor 13. If warp tension is low, additional liquid is supplied to line 25a. Pressure relief valves 35 and 36 acheive a constant pressure at both motor inlets, the speed of motors 13, 10 being varied by valves 22 and 27 respectively. Solenoids 32, 32', 33, 33' are operated manually or by a memory to operate selector valves 21 and 29 to halt or reverse the motors e.g. to lock warp beam 11 and reverse take-up roller 1 while supplying liquid from an auxiliary pump 40. Line 41 may be connected .to a pressurised liquid source.
