The RDA for automatic hydraulic straightening machine for linear blades is designed to straighten steel blades with or without HM cutting edge, paper knives, guillotine blades, and all the blades that are generally used in the paper industry.
The blade is moved back and forth by 2 motorized rollers, with blade position sensors reversing the blade direction. The upper roller exerts a force proportional and opposite to the blade deformation sensed by the system. The automatic cycle is completed when the deformation measured is within the range of acceptability defined by the operator.
The straightening of blades is very important in order to ensure greater cutting efficiency when coupled with good sharpening and deburring.
