ABSTRACT:
A paper web threading apparatus for use in a paper web handling machine includes a paper web threading member movably disposed substantially along a paper web threading path; a driver for driving the paper web threading member; a first signal generator for outputting a signal in response to the movement of the paper web threading member; a processor for receiving the signal outputted by the first signal generator as an input thereof, processing the signal so as to obtain a processed value relating to the speed of movement of the paper web threading member, and comparing the processed value with a reference value preset in connection with the operating speed of the paper web handling machine when the paper web is threaded along its paper web threading path, and then outputting an adjusting signal depending on the result of comparison; and an adjusting device for receiving the adjusting signal outputted by the processor as an input thereof and adjusting the driver so as to vary the speed of movement of the paper web threading member.
