Abstract: The invention pertains to a special process and devices for the production preferably by machining of workpieces with non-circular outer and inner contours such as squares, hexagons, ellipses, polygons and the like, or eccentric circular bores and/or tappets. In the claimed process, the workpiece is rotated at constant angular velocity while a tool (e.g. the blade of a lathe tool) set eccentrically in relation to the workpieces if moved without rotating about is own axis at controllable speed in a circular path, workpiece and tool being moved towards one another in cycles with the appropriate advance. This ensures that apart from a small cuttings volume far each advance, very narrow tolerances can be set.

The tool head comprises a base body (12), a tool shank (16) which protrudes axially over the base body (12) and is coupleable to a rotating machine spindle (14), and a thrust member (18) which is movable with respect to the base body (12) and which serves to move at least one tip holder or cutting tool (76). Further, an electric motor arrangement (24), which is coupleable to the thrust member (18), and a power supply device (26) for the motor arrangement (24) are positioned on the base body (12). In order to ensure a compact construction having an efficient motor arrangement, a hollow shaft (50) is borne rotatable about an axis of the base body (12), which is concentric with respect to a displacement axis (52) of the thrust member (18), and the hollow shaft (50) has an internal thread which engages in an external thread (42) of the thrust member (18).

The workpiece is supported so that the characteristic axis has a pre-established orientation, in other words a pre-established colatitude and longitude relative to a three-dimensional Cartesian reference frame which is defined by three mutually perpendicular axes, while the workpiece head can rotate about an axis of rotation which is inclined with respect to all three axes of the three-dimensional Cartesian reference frame and has a colatitude and a longitude other than those of the characteristic axis of the workpiece or of the tool.

Abstract: A machine for cutting slices from a cylindrical workpiece such as a log of pressure sensitive tape. The machine has a machine frame and a mandrel on the frame for holding and rotating the cylindrical workpiece. A disc shaped cutting blade is mounted on a carriage and is movable to cut the workpiece into material slices. The carriage is movable to shift the cutting blade to locations along the mandrel at which the workpiece is cut into slices. A drive mechanism is connected to the carriage assembly for moving the carriage assembly along the mandrel. That drive mechanism has a drive handle which can be manually gripped to disengage a drive rack and pinion and so enable movement of the carriage assembly in either direction along the mandrel. A one-way clutch mechanism connects the handle to the pinion so that rotation of the handle in alternate directions incrementally moves the carriage assembly in one direction only along the mandrel.

Abstract: A portable pipe cutting machine comprises a frame, an arm having opposite ends and supported on the frame for pivotal movement about a pivot axis between the opposite ends, a cutting wheel rotatably mounted on one of the ends of the arm, and a hydraulic piston and cylinder unit between the frame and the other end of the arm for pivoting the arm to displace the cutting wheel toward a pipe to be cut which is supported on rollers mounted on the frame beneath the cutting wheel. A manually operable variable displacement pump delivers fluid under pressure to the piston and cylinder unit to displace the arm toward the pipe, and an electric drive motor unit is supported on the arm for displacement therewith and includes an output end axially slidably interengaged with a drive shaft for the cutting wheel.

Abstract: A device for cutting off the top part of a container such as a bottle neck, comprising a plurality of pivoted arms operating like nippers gripping round the bottle necks and which carry each one at least at one of their ends a cutting form roller disposed between two form rollers for driving and guiding the bottle necks, the device allowing the indivudual cutting of closed bottles of plastics material adapted to contain any food liquid such as milk for instance.

Abstract: A method and an apparatus for packaging paper rolls (2), wherein a wrapper sheet (1) of such a size as to exceed the axial length of the roll is wrapped around the roll and the width of the wrapper sheet is reduced to a size corresponding to the length of the roll by removing the part (5, 6) of the wrapper sheet which extends over the ends of the roll. The header sheet (14, 15) which is bigger than the end surface of the roll, is placed on the ends of the roll and reduced to a size corresponding to the diameter of the roll or smaller by removing at least the part of the header sheet extending over the end surface. Thereafter the header (14, 15) and the wrapper (25) are secured to each other so that a tight joint is formed.

Abstract: An apparatus for processing especially heavy metal tubes comprises a frame supported by wheels, the frame having a plurality of supports consisting of rollers which may together support the tube to be processed. With a support which is quickly movable along the frame a bearer is associated which carries a processing tool, e.g. a grinding cross cut machine, as well as driving means for mechanically putting the tube into rotation during a processing operation. The driving means may also be used for giving the tube a longitudinal movement during simultaneous rotation thereof.

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: A device for cutting a metal or plastic jacket which surrounds a layer of foam on an insulated pipe is the subject of the present invention. A circumferential track mounts on the jacket and a ring gear is movable in the track. The cutting means is mounted on the ring gear for movement therewith. The cutting means is pivotally mounted so that it may assume a first position out of cutting engagement. Even in its non-cutting position, however, the leading edge of the cutting means will contact the jacket and movement in a circumferential direction will cause the cutting edge to penetrate the jacket and urge it into its cutting position. A motor is provided to drive the ring gear and cutting means around the track.

Large, vertically mounted, circumferentially slotted wheels each adapted to receive a circular cutting blade in each slot, receive the tires. The cutting blades are mounted overhead on a shaft which traverses a pivotally mounted beam which is raised and lowered by a piston. A brake is provided for engaging the tread of the tire, and tensioning means engages the lower rim of the tire to exert a downward pressure when the overhead beam is lowered. Turning power is provided to the cutting blades by means of belts or chains which connect a motive source with the shaft on which the blades are mounted. Collars on either side of the cutting blades engage the tire tread when the blades are lowered to turn the tire. A plurality of slots and corresponding cutting blades can be provided for each wheel with spacers to determine the width of sections cut from the tire.
