Maxson Automatic Machinery Company offers a feature on its precision sheets that ensures the skids of sheeted stock delivered to the printing press are free of splices that could smash blankets and cause press downtime. A capacitance-type splice detector is mounted prior to the cutter infeed. The detector senses a change in web thickness and signals the reject gate to divert the spliced sheet at speed up to 300 cuts per minute.
The controls for the splice detector are conveniently located near the monitoring equipment. Adjustment of the detector’s sensitivity is simple and straight forward and has the added benefit of detecting a single splice within a pack up to eight webs.
