ABSTRACT:
A neck down cutter for notching parallel sides in a rectangular sample of corrugated material to be subjected to edge crush testing is disclosed. The cutter comprises a suction box formed with a recessed surface in the top thereof through which a motor driven cylindrical cutting element projects for rotary movement about a vertical axis. The recessed surface defines a slide path for a sample holder formed with a recessed positioning slot which receives the side edges of the sample material being cut. The sample holder is movable between a non-working position (out of cutting contact) into a working or cutting position with the cutting element. A supporting notch in the sample holder is itself initially formed via contact with the cutting element to accurately register and support the notch formed in the specimen during subsequent cutting. A method of cutting notches in rectangular corrugated test specimens is also disclosed.
