Abstract
Apparatus is described for moving a sheet to be machined in a step-by-step fashion. A continuously running machine, illustratively in the form of a printer, is disposed at a machine station. A motor drives a sheet mover to move the sheet in a first direction and in a second, opposite direction along a path past the machine station. The motor is selectively energized by a motor controller operating sequentially in a first mode to energize the motor whereby the sheet mover accelerates the sheet from a rest condition, in a second mode to energize the motor whereby the sheet is moved in the first direction synchronously with respect to the continuously running machine, while the continuously running machine machines the sheet, in a third mode to energize the motor to deaccelerate the sheet to rest condition, and before the next first mode, in a fourth mode to energize the motor, whereby the sheet mover moves the sheet in a second opposite direction a distance substantially equal to a sum of the distances that the sheet is moved during the first and third modes.
