MAXSON AUTOMATIC MACHINERY COMPANY (Westerly RI USA) offers a retrofit package that upgrades existing stationary bed knife cutters with state of the art dual knife rotary cutting technology. The compact design allows for straightforward replacement of the older cutter with minimal interruption of ongoing production. The retrofit package can be fit to any rotary sheeter. The two cross cutting revolvers increase production by allowing knife loading up to 1000 pounds/3300 ft2 (800 grams/meter2). The unique blade adjustment clamps allow fine tuning of the cross cut blades and extends knife life to four times that of conventional cutters. The dual knife design mounts both top and bottom blades in rotating cylinders coupled together with anti backlash gearing. The synchronized speeds of the blades to the web result in the cleanest, quietest, dust free cross cutting action available. Outfitted with digital electronic controls, accuracies within + 0.010” (+ 0.254 mm), are maintained. Because the speeds of the blades match the speed of the web at time of cut, no adjustment for squareness is required.
