ABSTRACT:
A non-contact measurement and cutting device for cutting sheets of predetermined length from a roll of material comprises a frame having feed rollers journalled thereon and a feed roll drive for actuating the feed rollers. Cooperating cutting blades are carried on the frame for cutting the material. Also supported on the same frame or a separate adjacent frame is a conveyor and an optical sensor for sensing the lead edge of material to be cut. The optical sensor can be adjustably positioned between a minimum reference position to enable cutting of a relatively short length of material and a maximum reference position to enable cutting of a relatively long length of material. The control includes a data acquisition, computer, power supply amplifiers, an operator interface, a dual channel converter assembly, a precision linear control and a feed roll motor controller for accurately controlling the position of the camera and the movement of the feed roll motor so as to cut predetermined length of sheet material quickly and with great precision.
