  • Patent number: 4653361
    Abstract: The slicing machine has a mounting table carrying the workpiece to be sliced by the cutting blade. The mounting table is supported on an elastically deformable measuring plate of which the deformation is measured by a measuring transducer in a position as near as possible to the plane of the cutting blade wherein the cutting force is acting. The measuring transducer has very high sensitivity in order to detect deformations in the order of fractions of a .mu.m and is thus able to properly detect the value of the cutting force. The measuring system is spaced from the cutting blade and workpiece and does not hinder manipulation and accurate fine adjustment of the workpiece. On the other hand the accuracy of the measurement does not depend on the manner in which the workpiece is mounted. Preferably deflection of the cutting blade from its plane under the influence of the cutting force is also detected and an optimum control and supervision of the cutting process may be effected based on both measurements.

  • Patent number: 4269091
    Abstract: A machine for automatically cutting and dividing of cylindrical sleeves guided and supported on a drawoff spindle by means of a plurality of coaxially arranged rotary knives. The machine includes a transport arrangement for transporting an uncut sleeve onto the drawoff spindle where it is cut by the rotary knives and then transporting the now-divided sleeve onto an adjustable carrier sled which is transversely movably mounted relative to the axis of the drawoff spindle. The transport arrangement includes a pair of end pressure members which are movable toward and away from each other and which are adapted to grip the cut and uncut sleeve therebetween. The carrier sled includes a pair of adjustable parallel sleeve-receiving troughs which are adapted to be reciprocally mounted between precisely-defined relative positions with respect to the carrier sled and a rotary knife-supporting beam.

  • Patent number: 4251917
    Abstract: A portable drum opener tracks around a cover rim of a drum while cutting through an outer lip of the cover rim. It includes a rotatably driven drive wheel for engaging a radially inward facing surface of the cover rim for advancing the opener around the drum. A shaft that is movable toward and away from the outer lip of the cover rim carries a cutter wheel for pressing against and cutting through the outer lip in a region opposite the drive wheel. A pair of guide wheels are mounted for rolling against the outer lip of the cover on opposite sides of the drive wheel to support the opener during cutting, and a spring biased bracket urges the guide rollers against the outer lip of the cover. A lost motion coupling between the movable shaft and the guide roller bracket lets the guide rollers press independently against the drum rim during the cut but retracts the guide rollers away from the cutter rim when the cutter is retracted at the end of a cut.

  • Patent number: 4181050
    Abstract: A can end trimmer has a main rotary support shaft with a radial turret plate. A plurality of self-contained cutter unit cartridge assemblies have radial head flanges directly connectable to one side of the turret plate with driven members in each cutter unit cartridge automatically engaging control members mounted on the turret plate for effecting movement of a transversely shiftable cutter knife into engagement with an axially fixed cutter knife for effecting rotation of both knives to trim the end from a can held in a vacuum chuck. A shim between the cutter unit cartridge and the turret plate cants the axes of the knife members with respect to the can by a very small amount normally less than 2.0 degrees to effect a smooth burr-free cut of the can end. Stripper pin means surrounds the can being cut which in turn surrounds the axially fixed knife with a reciprocating stripper plate on the pins being easily removed during replacement of the cutter cartridge unit.

  • Patent number: 4130036
    Abstract: The apparatus includes a cradle for holding long tubes desired to be cut into individual tubes of shorter length. The cradle is generally cylindrical and mounted for rotation about its axis. Tubes are mounted in the cradle at a loading position, and a controller actuates a motor for driving the cradle inrotation to a cutting position. A plurality of saws are mounted on a shaft extending parallel with the axis of the cradle and rotating at high cutting speed. When the cradle is revolved to bring the tube to the cutting station, the tube is engaged by a surface belt drive to spin the tube in the cradle for cutting. In the case of tubes having greater wall thickness, the cradle is stopped momentarily just as the tubes are brought into cutting relation with the saws so that a partial peripheral cut is made while the cradle is stopped. The cradle is then continued to be rotated to complete the cut and to bring the cut tubes back to the original position at high speed.

  • Patent number: 4111084
    Abstract: An end-trimming apparatus for roll-like products. The apparatus trims both ends of a roll comprising a sheet-like material wound up on a core, particularly, stretchable one such as plastics film, by cutting off the irregularity of both the ends, finishing them into flat faces. It comprises a conveying means for carrying rolls horizontally to a given location, a supporting means of a pair of chucks for supporting the roll at both the ends, while providing it with a rotation in the winding direction of the roll, and a cutting means provided close to the pair of chucks, including a pair of disk cutters arranged co-axially and having respectively separate shafts parallel with the shafts of the chucks, the disk cutters being capable of moving toward and away from each other and of reciprocating in the direction at right angle to said toward-and-away motion.

  • Patent number: 4030385
    Abstract: A washer cutting machine is disclosed wherein a sleeve of an elastomeric material suitable for use as a washer is placed on a mandrel and rotated. A predetermined length of the sleeve extends beyond the end of the mandrel, and a knife-edge moves in a radial direction to cut a ring from the end of the sleeve of a width such that it may be suitable for use as a washer. The machine is programmed so that the steps of loading the sleeve on the mandrel, cutting a washer from the sleeve, advancing the sleeve the width of a washer to be cut at the completion of each cutting operation, and stopping operation of the machine after the last washer has been cut therefrom, are all carried out automatically.
