Abstract
Sheet material feeding and cutting device including feed roll for material driven by a motor through clutch and brake, for feeding sheet material such as paper from a roll. A knife is provided with driving means for operating the same in response to an electrical signal. The extent of movement of the feed roll is measured to thereby measure the amount of material fed. This may be provided by a shaft encoder which produces pulses for increments of movement of the feed roll, and a counter coupled to the encoder for counting the pulses. The counter can be manually preset to a particular number of pulses corresponding to a particular length of material, to operate a control circit in response to the preset number of pulses. The control circuit operates the electrically operated clutch and brake to disengage the drive and to stop the movement of the feed roll. The control circuit also applies a signal to the drive for the knife to operate the same. Alternatively, a mechanical device coupled to the feed roll can move therewith and cooperate with a switch which is adjustably positioned in accordance with a preset length of sheet material. The switch operates the control circuit to actuate the clutch and brake, and the drive for the knife, in the same manner as when the shaft encoder and counter are used.
