ABSTRACT:
A rotary feeder for paperboard blanks includes suction means, partially relieved feed wheels and a transmission with input and output shafts operatively connected so that the output shaft undergoes a controlled acceleration during an initial portion of each revolution of the input shaft and is stationary during a last portion of each revolution of the input shaft, whereby the wheels engage and grip a blank by means of static friction and move and accelerate that blank to the nip rolls without slippage occurring and so that each blank enters the nip rolls in register.
