Abstract
A web slitting apparatus comprises a pair of upper and lower disk shaped web slitting members having their peripheral edges in engagement and disposed for rotation about essentially parallel axes on opposite sides of the web to be slit. The lower web slitting member is driven by a motor having a printed circuit armature. The lower web slitting member and the armature are secured to the motor drive shaft so that when the motor is activated, it directly drives the lower slitting member. The motor is activated only during the initial threading of the winding apparatus to assist in slitting of the web, and during initial acceleration of the web up to the normal line speed, whereupon the motor is deactivated. The web cutting apparatus will thereafter be driven by frictional engagement with the web and continue to slit the web as a web driven slitter.
