Feeding and cutting control mechanism for roll stored paper

Abstract

A mechanism for withdrawing and cutting sheet from a storage roll thereof to predetermined lengths includes a feed roll driven by a clutch transferrable between engage and disengage conditions and a shaft rotatable single cycle cutting blade located forward of the feed roll. The shaft is spring biased in a blade sheet cutting forward direction and means are provided for loading the spring following its unloading. The shaft is releasably locked in a blade retracted position and is releasable by a first solenoid to effect a cutting cycle and a timing member rotatable with the shaft acts through a motion transmission to disengage the clutch and releasably lock it in disengage position at least during the cutting of the sheet. Following the cutting cycle, the clutch may be actuated to its engage position by the energization of a second solenoid. Alternatively, the clutch may be fully controlled by the second solenoid by a circuit network responsive to the positions of the timing member.
