Abstract:
A non-contact measuring and cutting device for cutting a web of material into sheets of desired length, said device comprising:a frame;a conveyor system supported by said frame, said conveyor system being capable of moving said web of material relative to said frame;a shear assembly capable of making a cut in said web of material;a control system operatively coupled to control the cutting of said web of material into sheets of material, said control system controlling the cutting of said web of material into sheets of desired length, said control system comprising:a sensor that senses a leading edge of said web of material;a controller operatively coupled to said sensor, said controller receiving a signal from said sensor upon said sensor sensing said leading edge of said web of material, said controller being programmed to cause said web of material to be cut by said shear assembly if the position of said leading edge is within a desired tolerance, said controller being programmed to cause said web of material to be repositioned and then cut by said shear assembly if the position of said leading edge is not within said desired tolerance, so that said sheets cut by said shear assembly have a length corresponding to said desired length; anda data storage device that records a length measurement for each of said sheets of material cut by said shear assembly to generate a statistical process control report.
