    摘要： An automatic border panel measuring and cutting machine wherein motorized pinch rollers feed a measured length of a mattress border panel and then stop while a pivotally mounted knife swings from a ready position through a cutting zone, in which it cuts off that measured length, and then returns to its ready position to start the next feed and cut cycle. The knife, which is pivotally mounted at one end, has its opposite or free end not only connected to an air cylinder piston, which moves the knife back and forth for cutting and return purposes, but also engaged, during the cutting movement, by a yieldable guide means which directs the cutting edge of the knife into progressively tighter yieldable cutting (and knife-sharpening) engagement with a fixed cooperative cutting edge on the machine. The air cylinder is mounted for right and left and for front and rear pivotal movements to accommodate the corresponding movements of the blade.
