Abstract: A paper stacker for stacking a continuous paper web in fan-fold form from a printer is disclosed. Rollers having radially projecting resilient fingers engage both folded edges of the web as it is stacked. The rollers are each driven by a motor through a gear secured to the roller shaft. The motor is carried on a plate pivotted about the shaft the plate being held against rotation about the shaft by a spring. When the stack height brings the upper surface of the stack sufficiently close to the rollers the load on the rollers is sufficiently great to cause rotation of the plate against the tension of the spring, thereby making an electrical contact to actuate mechanism for raising the rollers.
