    Patent number: 5566604
    Abstract: A machine for producing braid or circular knit fabric has a withdrawal unit for the continuous product driven by a synchronous motor receiving its drive signal from a digital frequency converter. A pulse generator connected with the main motor of the machine produces pulses representing the speed of the main motor which are integrated and applied to a multiplier introducing the proportionality factor between the main drive and the withdrawal drive. That multiplier has an output which is applied as the input to the digital frequency converter.
