Abstract
An apparatus for feeding sheets comprises a variable speed conveyor for feeding a sheet cut from a web. A high speed conveyor receives the sheet fed by the variable speed conveyor, and feeds it at a high speed v1. A cutting completion detector detects the separation of the sheet from a cutter and generates a detection signal. A controller adjusts the feeding speed of the variable speed conveyor to a feed speed v2 as long as the leading portion of the web is being fed to the cutter, adjusts the feeding speed to a speed v0 (v0<v1, v2), at which the sheet is kept stationary with respect to the cutter, during the time from when the cutter starts cutting the web to when the cutting is finished and the cut sheet separates from the cutter, and increases the feeding speed from the speed v0 to the speed v1 during the time from when the detection signal is generated to when the sheet arrives at the high speed conveyor.
