Abstract: For the cutting of a web a circular cutter is journaled rotatably in a slide which is moved along the cutting line by means of a linear drive. The cutter has a disk-shaped base body journaled freely rotatable which upon its perimeter is provided with pointed cutting blades angled in the sense of rotation. The distance of the base body from the web is chosen such that only the cutting blades but not the base body penetrate the web. Furthermore, the cutting blades are so fashioned and arranged that upon their penetration of the web to the maximal depth of penetration, an uncut portion remains between two cutting blades which upon exit of the subsequent cutting blades is severed by their leading cutting edge.

Abstract: A transverse cutting device for cutting into lengths a strip traveling continuously along a predetermined path, which device presents a drum for feeding and guiding the strip through a cutting station; and a cutting unit for successively cutting the strip transversely; at least one cutting element on the cutting unit being moved along an annular path lying in a plane intersecting the path of the strip in the cutting station, and along a given line forming an adjustable angle with a transversal intersecting the path of the strip; and the roller presenting peripheral grooves for longitudinally stretching the strip in the cutting station.

Abstract: A high volume food loaf slicing machine in which a rotating and orbiting knife slices the loaf as it advances through a slicing station. The turbulent air generated by the rotating and orbiting knife is reduced in the vacinity of the stacking slices by baffles and is redirected through a vent port and away from the stacking slices.

Abstract: A machine for cutting slabs of frozen meat into cubes comprises a rotating cutting drum having alternatingly disposed slitting discs and knife discs. The slitting discs have a contour to minimize the risk of fracturing upon penetration into the meat in that the slicing edge thereof extends over a substantial portion of their circumference and slices the slab into a plurality of strips which are cut into cubes by the knife discs.

Abstract: A method and device are described for producing slitted plastic film sheets of the type used for wrapping lettuce and similar produce. A form of punch press is used with an upper ram and lower platen and a tray moves in and out horizontally between the ram and platen. On the tray is a die with slitter blades over which is placed a stack of plastic film sheets. The tray moves in and the ram presses down on the sheets, cutting slits through the stack. Then the tray moves out and the stack of slitted sheets is removed. A single operator can produce 450 slitted sheets per minute with this system.

Abstract: Envelopes are opened by standing each envelope on an edge thereof in a guide channel and moving the envelope on edge along the channel into and through a cutting zone where one or more knives being rotated on a flywheel rotor continually move past an anvil and slice off a succession of narrow elongate segments of the border of the envelope. The segments are thrown from the cutter and fall by gravity into a collecting receptacle. Each knife has a cutting edge formed with at least one leading point and with cutting edge portions trailing from the point. Each segment is sliced off by first puncturing the envelope at a point in its border and then slicing it from that point across and along its edge.

Abstract: In a reciprocable circular saw, coplanar mounting of the machine carrier surfaces which constitute the table surface is achieved in that the legs of the frame have horizontal upper portions whose undersides constitute flat horizontal surfaces. The machine carriers are secured to the legs so that the surfaces which constitute a table surface abut against the first surfaces of the legs.

Abstract: A brick-cutting machine having an axially rotating reel with sets of radially disposed, spring-tensioned cutting wires is equipped with resiliently compressible, rubber cushion blocks or pads positioned to cushion and limit rebounding movement of the wire-tensioning springs and thereby prevent the application of excessive and destructive tension forces to the cutting wires of the reel.

Abstract: A nibbling tool for contour cutting and for forming holes in a plate or the like, comprising one movable and one stationary member, and a supporting element with a shaft. The shaft has a first longitudinal axis, and the supporting element is rotatable about that axis by a motor, is adjustable in an axial direction, and may be set in a predetermined relationship relative to the stationary member. The movable element has a second longitudinal axis and is rotatable therearound. The axes subtend an acute angle with one another for the movable element to have a predetermined spaced relationship with respect to the supporting element, so that a plate may be inserted between the stationary member and a point of the movable member closest to the stationary member upon the supporting element having been set with respect to the stationary member.

The other wheel carries a plurality of cutting punches, each of a size and arranged to fit between the pair of limbs of a bridge-shaped cutting element on the other wheel to provide a shearing action upon engagement with the limbs of a said cutting element.

Abstract: A cutting implement having a plate with a curved, sharpened edge which is rotated to traverse the location of a work piece. The plate is shaped so that the rate of advance of the sharpened edge through the location decreases as the angle of rotation increases, thereby compensating for the gradual reduction in the mechanical advantage, and producing a nearly constant power requirement.

Abstract: In the cutting of asbestos sheet or the like, the sheet is supported on a bed and a cutting blade is advanced through the sheet and through a narrow slot in the bed below the sheet. The cutting edge of the blade has a flat transverse profile so that the sheet is cut by the action of the blade in shearing from the sheet a strip of the same width as the blade. The cutting edge preferably makes a constant angle with sheet at the point of shearing as it moves through the sheet.
