Abstract
A cutter instrument for precision cutting of a corrugated sheet into a precision cut square for edge crush testing is disclosed. The cutter includes a base plate and a pair of cutting blades slidably mounted to the base plate for cutting movement in a direction parallel to a first guide rail. Positioning of the corrugated sheet against the first guide rail allows the sheet to be cut into a longitudinal strip of predetermined precise width. A pair of second guide rails spaced from each other by the predetermined width allows the strip to be rotated 90.degree. and positioned between the second guide rails and respective abutting contact therewith. Movement of the cutter blades along the cutting path completes the cutting of the strip into a precise square.
Claims9
A cutter instrument for precision cutting a sheet object into a precision cut sample of predetermined dimensions, comprising:
- a support base for supporting said sheet object for cutting;
- a cutter on said support base and including at least one pair of cutting blades being substantially parallel with and spaced a predetermined precision distance from each other for cutting said precision cut sample from said sheet object;
- a bearing arrangement mounted on said support base for movably mounting said cutter to said support base and for directing the movement of said cutter along said support base to obtain said precision cut from said sheet object;
- a first guide mounted on said support base and including a guide surface extending in the direction of movement of said cutter, said sheet object being positioned with said first guide for predetermined alignment with said cutter;
- a second guide including a second guide rail mounted on said support base and extending perpendicular to the moving direction of said cutter and including a guide surface against which said sheet object is positioned for further predetermined alignment with said cutter;
- and
- at least a pair of cutting grooves in said support base at locations respectively corresponding to the respective paths of movement of said cutting blades to thereby respectively receive the cutting edges of said cutting blades, wherein said cutting grooves extend through the second guide rail so as to define an uninterrupted, continuous cutting path through which the cutting blades respectively move through the second guide rail.
