Experimental analysis of corrugated fibreboard cutting with movable cutting disc during large-sized package manufacture.

The paper reports experimental research of loads (torques) that arise during cutting of corrugated fibreboard specimens by a movable cutting disc and immovable counter blades. The paper shows a method of corrugated fibreboard cutting based on the use of immovable counter blades and the cutting disc with reciprocating motion driven by electric engine. There has been designed and created experimental test bench for the research of corrugated fibreboard specimen cutting. The authors have used the strain gauge method for torque research that made possible to get their trustworthy values. The paper shows experimental research results that define technological parameters of corrugated fibreboard cutting by movable cutting disc, which minimise loads on main shaft. Results of experimental research give opportunity to get trustworthy and systematised information about torque values depending on type and thickness of the corrugated fibreboard and the influence of flute direction, cutting disc movement velocity and overlap size of tool during corrugated fibreboard cutting. The use of movable cutting disc in technological equipment for corrugated fibreboard cutting creates preconditions for high-quality manufacturing of large-sized packages from corrugated fibreboard, decreases overall dimensions and simplifies equipment design, minimises power discharge and packages manufacturing time.
