Abstract: A tissue harvesting method and device for obtaining micrograft tissue particles within the size range of 50-1500 microns, and more preferably 500-1000 microns, and most preferably 600 microns. The particles may be processed after a piece of donor tissue has been excised from the donor site, or processed into the desired size directly at the donor site, and thereafter excised. Cutters having blades or cutting edges spaced in the range of 50-1500 microns are utilized to obtain particles within the desired size range. An elastomer is positioned between the cutting edges to push the excised particles out of the blades for ease of use.

Abstract: A rotary punch includes an upper die plate, a lower die plate, and a support frame having a drive assembly that moves the upper die plate horizontally and vertically along a generally circular pathway. The lower die plate is connected to the support frame for movement in a linear horizontal direction only. The upper die plate is vertically slidably connected to the lower die plate by way of one or more vertical rods attached to the upper die plate that extend down through bushings provided in the lower die plate. In operation, the lower die plate horizontally follows the upper die plate as the latter is moved along its circular pathway. Concurrently, the upper plate moves towards and away from the lower plate. This maintains a substantially constant alignment between the die plates for carrying out a periodic machining operation on a moving web of material passing there between.

Abstract: The described method serves for trimming or cutting during conveyance in a conveying direction (F) substantially in parallel to their main surfaces, flat objects along predetermined cutting lines parallel to the conveying direction (F). The objects are conveyed between a first and a second cutting edge (SK1 and SK2) and are cut by a relative movement of the two cutting edges. The first cutting edge (SK1) is positioned, e.g. stationary, in the plane of a support surface supporting the objects and for each cutting process, the second cutting edge (SK2) is moved past the first cutting edge in such a manner that at least the cutting point on the second cutting edge has a speed component in conveying direction (F) which has the same size as the conveying direction and a speed component perpendicular to the support surface.

Abstract: Lack of balance of a crank mechanism, which reciprocates a ledger having one or more guides for one or more cigarette rods or filter rods each issuing from a maker and being subdivided into a row of cigarettes or filter mouthpieces, is at least partially counteracted by at least two counterpoises one of which orbits about the axis of the crank mechanism in a first direction and the other of which orbits, in a second direction counter to the first direction, about a second axis laterally offset relative to the axis of the crank mechanism. A third counterpoise can be mounted for orbital movement about the axis of the crank mechanism and, if utilized, is angularly offset relative to the first counterpoise. The prime mover for the crank mechanism orbits the first and (if provided) third counterpoises in the first direction, and (e.g., by way of a V-belt) the second counterpoise in the second direction.

Abstract: An apparatus for cutting, including an anvil cylinder which may have a plurality of cut rubbers strips affixed around the anvil cylinder and a cut cylinder which is mounted for rotation about an eccentric axis. Two knife boxes may be mounted on the cut cylinder, each knife box having a knife and cheekwood for securing the knife to the cut cylinder. A paper tape guides the material to be cut between the cut cylinder and the anvil cylinder. When one knife box degrades, a knife sleeve on the cut cylinder can be indexed so that the other knife box takes the place of the degraded knife box. When a cut rubber strip degrades, the anvil cylinder can be indexed so that another cut rubber strip takes the place of the degraded cut rubber strap. Either of these functions can occur while the apparatus is still running. The anvil cylinder can also use a cut rubber sleeve.

Abstract: A continuously-fed flat tube is cut into sub tubes each having a given length. The flat tube has multiple ports therein. A pair of roller cutters are enabled to follow the flat tube at a zero relative speed between the roller cutters and the flat tube. The roller cutters are moved across portions of the flat tube respectively to cut the flat tube while the roller cutters are enabled to follow the flat tube at the zero relative speed. At least one of the roller cutters enters the flat tube by a depth equal to or greater than a half of a distance between outer flat surfaces of the flat tube while the roller cutters are moved across the portions of the flat tube.

Abstract: A clipper for cutting wood or plywood veneer transversely and other similar continuous sheet materials is described which ensures that the sheet material is cut in alignment and the cut achieves a square edge on the material. The clipper includes at least a pair of guillotine knife blades, each blade extending transverse to the sheet material, each blade cutting against a single anvil cylinder rotating in synchronization with the sheet speed. Each blade is preferably mounted in an actuating assembly which includes a crankshaft and a connecting rod. The blade is journaled to the crank of the connecting rod at its lower portion. The upper end of the connecting rod is guided along a radial line with respect to the center line of the anvil. Upon turning the crankshaft, the blade advances simultaneously vertically and horizontally into contact with the veneer. The imparted motion is such that the blade always remains substantially perpendicular to the surface of the veneer being cut.
