Abstract: The invention is a honeycomb core cutting tool wherein a primary cutter is used to cut the core to shape and secondary cutters are used to immediately shred that portion of the core being removed. The primary cutter is typically a commercially available circular saw blade modified by the machining of a plurality of peripherally located, radially inward directed slots dividing the primary cutter into segments which can be formed into a concave shape. A retainer threadably engages the end of the shaft and is used to force the primary cutter against a concave surface of a flange mounted to the shank of the tool, causing the primary cutter to deform into the concave shape. Mounted behind the flange and primary cutter are two "slot" cutters for shredding the portion of the core being removed.

The inboard end of the shaft is adapted to be received by rotational motion imparting mechanisms. The assembly also includes a chip breaker/chaf remover device having a central bore mountable over the shaft with its outboard face in contact with the inboard face of the cutting knife for rotation therewith during operation and use. The radially outward edges of the chip breaker/chaf remover device are formed as sharp breaker edges for breaking the material cut by the cutting knife.

Abstract: A rotary cutting mechanism for transversely slicing an elongated rotatably driven roll of material such as plastic film into a number of narrower rolls includes a pair of spaced-apart knife cutting blades mounted for free rotation about an axis parallel to the longitudinal axis of the roll. A rotary saw blade is mounted intermediate and in axial alignment with the cutting blades, and is independently driven to remove material between the cutting blade edges as the blades are moved together to slice the roll. The finished narrower cut rolls therefore exhibit smoothly finished side edges and are readily separable from each other, there being no frictional heat developed by the cutting blade edges which are free to turn with the material on the roll as they slice through it.

Abstract: Apparatus for cutting rolls of sheet material is provided with a pair of longitudinally stationary parallel knife blades positioned on opposite sides of a band saw blade which moves longitudinally to remove swarf from between the knife blades. The knife blades are supported on a blade carried band which is held under tension between spaced apart points on a mounting frame. A longitudinal gap in the knife blade exposes a section of the band saw blade to cut the core of a roll of sheet material.

Abstract: Method and apparatus for trimming cylindrical articles, particularly can bodies, to a predetermined longitudinal length by sequentially feeding such cylindrical articles into carriage pockets rotating around a main shaft synchronously with an axially aligned plunger at one end of each carriage pocket and a similarily aligned mandrel at the other end of the carriage pocket. At predetermined positions, the plunger moves into the aligned carriage pocket and pushes a cylindrical article therein onto an aligned mandrel which is rotated around its own axis as well as around the main shaft. As the mandrel rotates, a fixed arcuate blade which cooperates with a cutting edge defined in the mandrel is engaged to shear an annulus portion from the end of the cylindrical article thereby trimming the cylindrical article to a predetermined and repeatable length. Upon severing of the annulus, a fixed cutter blade engages the annulus to transversely cut the annulus into an open ring.
