ABSTRACT:
Apparatus for temporary storage of partially overlapping paper sheets has a first rotor driven by a first variable-speed motor and a second rotor driven by a second variable-speed motor. The first and second ends of an elastic band are connected to the respective rotors and a conveyor system delivers successive sheets onto the band ahead of the location where the unconvoluted portion of the band merges into the outermost convolution when the first rotor is driven in a direction to collect the band. The radius of the growing roll of sheets and convolutions of the band on the first rotor is monitored by a first detector which transmits corresponding signals to a signal processing circuit further receiving signals which denote the speed of the conveyor system. Such signals are processed to form a third signal denoting the desired angular speed of the roll on the first rotor, and the third signal is compared with a fourth signal which denotes the actual angular speed of the first rotor. The motor for the first rotor is adjusted when the angular speed of the roll deviates from the desired speed as denoted by the third signal.
