DEFINITION
Classification: 271/249
(under subclass 248) Device provided with both a positioning means and a gripper-couple mechanism that move together with a relatively small degree of movement, the direction of movement being transverse to the direction of sheet movement.
(1) Note. In the device of this subclass, an open sheet-gripper, together with the aligner, move toward a sheet, the side edge of which is contacted by the aligner, after which action the sheet- gripper closes and the mechanism returns to a position at which the sheet is aligned, at which point the sheet- gripper is opened to release the aligned sheet and the sequence is repeated on a next sheet. Compare this with the device of subclass 252.
