Exclusive Design Permits Cutter Knife Tuning While Running
An innovative approach integrated within its dual knife rotary cutter by MAXSON AUTOMATIC MACHINERY COMPANY (Westerly RI) allows an Operator to make adjustments to the cross cutting knives while the sheeter is operating. This feature provides the benefit of cleaning the cut edges of the sheet without stopping the machine and insuring Operator safety.
In this sheeter design, the cutting section includes knives mounted in an upper and lower rotating cylinders. Using the exclusive clash arrangement, the Operator can safely adjust the cross cutting blades while the cutter is running, by transversely shifting the upper cylinder across the width of the cutter to increase (or decrease clash). This allows the Operator to improve cut quality while running the sheeter.
By turning the clash adjustment the upper knife revolver can be incrementally moved using fine threaded progression. Moving the top cylinder in against the bottom revolver has the effect of increasing knife overlap, compensating for blade wear. Moving the upper revolver back out has the effect of backing away the interference between the two blades when cutting thicker materials.
Since this adjustment is done without stopping the machine, the design affords the Operator to react to cut quality issues as they occur without the time consuming process of stopping the sheeter and tuning the cross cutting blades.
