Abstract (en)
[origin: EP0188035A2] A hydraulic cylinder (106) controls linear traversing movement of a spooler (16) under the control of a high speed servo-valve (136) that in turn is controlled by electronic circuitry. Position, velocity and rotation speed transducers (106, 114 and 116) for the spooler and a position transducer (118) for a strand (18) being wound onto or unwound from the spool provide input signals to the circuitry.
