This method, which cuts the edges parallel, is the easiest and most repeatable method of preparing samples for Edge Compression Testing.
Two sharp, single bevelled parallel blades are located in the pneumatically driven cutter head. The blades are moved at high speeds to ensure straight and parallel edges with square corners. Its one step, easy operation is guarded by a polycarbonate safety screen to protect the operator.
The Edge Compression Guide Blocks are to aid in the determination of the resistance of corrugated fibreboard to a load applied in the plane of the board in a direction parallel to the flutes, ie: parallel to the cross direction of the component sheets. This knowledge can be related to the compression strength of containers when constructed with flutes vertical in vertical faces.
