Cloth draw-off apparatus for a weaving machine

Claim 1

A cloth draw-off apparatus for drawing-off cloth woven from warp threads and weft threads in a weaving machine containing a rotatable main shaft, said cloth draw-off apparatus comprising: a cloth draw-off roll operatively connected with said main shaft of the weaving machine; regulating means operatively connecting said cloth draw-off roll and said main shaft of said weaving machine; said regulating means containing a controllable motor drivingly connected with said cloth draw-off roll; said regulating means further containing a regulating circuit arrangement connected forwardly of said controllable motor in order to control weft thread density as a function of at least the rotational angular position of the weaving machine main shaft; said regulating means containing a modulator; said modulator being operatively connected with said controllable motor; a pre-programmable programming stage operatively connected with said modulator and generating control commands; an input device for pre-programming said programming stage; said modulator receiving said control commands and transforming the control commands into control signals for controlling said controllable motor; a pulse transmitter arranged at least at said main shaft of the weaving machine and generating pulses indicative of the rotational angular position of said main shaft of said weaving machine; said pre-programmable programming stage being connected with said pulse transmitter and receiving therefrom said pulses indicative of said rotational angular position of said main shaft of the weaving machine; a control circuit arrangement generating information signals indicative of the momentary functional state of the weaving machine; and said pre-programmable programming stage being connected with said control circuit arrangement and receiving therefrom said information signals indicative of said momentary functional state of said weaving machine.
