Abstract (en)

[origin: US5060878A] An unwinding device for a machine for the processing of strip material has a pair of arms which receive the roll between them and are movable toward and away from one another by a spindle having threaded portions of opposite hand engaging the respective arms. A bearing sleeve axially entraining the spindle is engaged between the fork shanks which are connected to a piston rod of a double acting cylinder mounted on the traverse along which the arms are guided to adjust the arms in axial direction transverse to the web feed direction.
