Abstract: A cutting tool has a cutting head, a motor and a transmission means drivable by the motor. The cutting head comprises first and second cutting members, wherein the first cutting member is pivotably moveable with respect to the second cutting member. At least the first cutting member is drivable by the transmission means between a first angular position with respect to the second cutting member and a second angular position with respect to the second cutting member, in which a space between the respective cutting blades is closed. The transmission means is a bevel gear on the output shaft of a gearbox which conveys drive power from the motor to the drive gear. The bevel gear directly engages a bevel wheel member connected to the first cutting member and which swivels with the first cutting member about the same swivel point. A controller comprises main, first and second switches which control the motor to move the first cutting member (movable blade).

Abstract: The present disclosure provides cutting tools which include a handle coupled to a rotatable shaft having shallow grooves that extend substantially entirely across the surface of the rotatable shaft. The grooves define sharp cutting edges. In particular examples, the cutting edges are continuous, such as being defined by helical threads. The present disclosure also provides methods of dissecting a substrate of cultured cells. The substrate of cultured cells is separated into separated portions with a cutting tool. The cutting tool includes a rotatable shaft having a cutting blade which extends around the shaft. The cutting blade is rolled through the substrate to cut the substrate into portions. The portions are separated from one another to dissect the substrate.

Abstract: A food product slicer includes a base and a knife mounted for rotation relative to the base. A slide rod extends in a direction past the knife. A carriage assembly is mounted for reciprocal movement back and forth past a cutting edge of the knife. At least one bearing arrangement connects the carriage assembly to the slide rod to facilitate the reciprocal movement of the carriage assembly. The bearing arrangement includes a lubricant reservoir. A bearing bracket holds a bearing that rides on the slide rod. The lubricant reservoir is fluidly connected to deliver lubricant to the slide rod in proximity to the bearing.

Abstract: An apparatus and method for cutting soft materials such as meat. Two or more spirally mounted helical blades are situated between two supports, and the supports are mounted to a shank. The shank is rotated to impart rotary action to the spiral shear blades, and the entire device may be used to perform various cutting operations. The distal or bottom one of the supports may also be a cutting blade, and a number of versions of bottom cutting blades are useable in the practice of the invention.

Abstract: Linerless labels are cut or burst from a web by passing the web through infeed and outfeed pairs of rolls with a separator device located therebetween. Each roll pair includes a friction surface for engaging the slick smooth surface of the web and another roll with a silicone elastomeric or plasma-coated surface for engaging substantially without gripping the exposed adhesive side of the linerless label web. In the cutting mode, a rotary blade severs the web against a fixed blade to form the label. The infeed rolls are backed up after each cut to break the adhesive bond between the web and the fixed blade and then reverse to advance the web through the cutting position and into the outfeed rolls for a subsequent cutting operation. The outfeed rolls continue to advance the cut linerless label to a receiving station. In a bursting mode, the web is perforated and a roller breaker bar is disposed between the infeed and outfeed rolls to break the web along the perforations to form the linerless label.

Abstract: Apparatus for perforating corrugated tubing of large diameter is achieved by use of multiple cutters disposed within the threading on the feeder-cutter wheels. The apparatus receives tubing to be perforated along an axial path coincident with the axis of the tubing. A plurality of feeder-cutter wheels drive the tubing through the apparatus and concurrently perforate the tubing in the valley of its corrugations by virtue of a plurality of cutters disposed within the threading. These multiple cutters allow perforation of larger diameter tubing in the range of nine to twelve inches. Each feeder-cutter wheel, and the drive shaft each wheel is mounted upon, is offset at an angle relative to the axial path, this angulation facilitating uniform perforations at higher speeds. This design permits the wheels to be interchangeable with different wheels, allowing the apparatus to perforate tubing of different diameters.

Abstract: A method and apparatus for producing homogeneous bread crumbs including a conveyor for conveying bread loaves that securely holds the bread loaves while they are sliced by a rotary involute knife slicer into slices of substantially uniform thickness, a dicer that dices the slices into homogeneous bread crumbs and a chute with a deflector and a compressed air source which conveys the bread slices from the rotary involute slicer to the dicer and aligns and spaces the slices for input to the dicer.

Abstract: An apparatus for cutting a continuous bar of cigarettes into individual cigarettes includes a cutter head supported rotatably on a first rotary shaft, a knife projecting from the cutter head, and a device provided in the cutter head for holding and advancing the knife. A second rotary shaft is coaxial with the first rotary shaft. A gear train is provided between the first and second rotary shafts for rotating the second rotary shaft at a speed which is slightly different from that of the first rotary shaft. The knife advancing device includes a feed screw member which is rotatable by the second rotary shaft.

Abstract: A pipe perforating apparatus has a spindle carrying a cutting tool and a drive for rotating the spindle about its own axis while revolving the spindle about the pipe. The cutter periodically engages and perforates the pipe. To provide for small, uniform sized holes in the pipe, the cutting tool is an end cutting punch and the spindle is rotated and revolved around the pipe to roll the punch into and out of the pipe without exerting a tangential force on the pipe.

Abstract: A device for cutting continuous rods of smoking products, in which a rotary cutting head is provided with a radial blade inclined with respect to the axis of rotation of the head, the blade being sharpened, upon each rotation of the head, by a frusto-conical grinding wheel carried eccentrically by a sharpening head rotatable about an axis substantially perpendicular to that of the blade carrier head, the radial position of the grinding wheel on the associated wheel-carrier head being adjustable together with the position of a counter weight, and the grinding wheel being carried into rotation about its axis by means of an air motor.

Abstract: An apparatus for slicing a meat product in which the cutting edge of a rotating involute slicing blade is advanced in synchronism with the feed of the meat product during the cutting of a slice from the meat product. There is also means for either mounting an involute slicing blade or arranging the cutting edge of an involute slicing blade.

Abstract: A new and improved apparatus and method for feeding fastener attachments and stock having a plurality of spaced apart cross links coupled to side members, and severing the side members between adjacent cross members to form fastener attachment devices, i.e., fasteners.

Abstract: A dual speed stacker assembly for use in connection with a high speed machine for slicing, stacking and weighing food products, which stacker has mating paddles which move at slow speed during the collection of the required number of slices in a stack and then are rotated at high speed to drop the stack of slices onto a conveyor and bring the blades into position to receive the next collection of slices, the said paddles being rotated by a low inertia D. C. motor connected by a timing belt and bevel gear arrangement.
