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.

Arrangement for the automatic control of the step-by-step advance of a

A circular knitting machine has a needle selection system which can be set up to provide selection under electronic control, or to provide for manual selection. The selection system has a plurality of slidable selection cams which are controlled by an electro-magnetic system to act on rocking selector jacks, the electro-magnetic system being operated by an electronic control program. For manual selection, the electro-magnetic system serves to hold all of the selection cams in an excluded position and selection is obtained by manually insertable cams which act on the selector jacks.
