    Abstract: Cutter for cross cutting of reeled webs comprising a rotary cutting assembly including a blade and a counter blade rotated in synchronism with an advancement assembly of the web. The rotation axes of the blade and of the counter blade are displaceable relative to each other, perpendicularly to the web, and a gear actuator is provided to operate mutual approaching thereof when the blade and the counter blade are placed in a mutually facing angular position for cutting the web. The blade and the counter blade are rotated only at the time of cutting.

  • Patent number: 6173633
    Abstract: A variable length rotary cutting system for cutting sheet material in various desired cut lengths, including a knife roll and an anvil roll between which the sheet material is passed for cutting. A drive system drives the knife roll at varying speeds during a cycle of rotation and includes a drive gear and an offset gear mounted in an off-center mounting so as to be rotated at varying speeds by the drive gear. The rotation of the offset gear is transmitted to the knife roll so as to cause the knife roll to rotate at varying speeds about a cycle of rotation to enable the knife roll to cut varying lengths of the sheet material.

  • Patent number: 5486221
    Abstract: Opposed shear assemblies are conjointly driven via a rack and pinion assembly by a servo motor which follows a displacement profile. When the cycle rate exceeds a selected limit the profile is scaled to reduce peak motor velocity and a shorter stroke is defined.

  • Patent number: 5018417
    Abstract: The graphic tape slicer comprises a frame having a feed guide at the rear end for receiving the graphic tape from a roll. A cutting blade is mounted in the center of the frame on a traveling blade holder that engages a threaded rod. Rollers through which the tape is extracted are mounted on the front of the frame. The extraction rollers are joined by a pulley arrangement to the threaded rod. When the graphic tape is extracted from the slicer, the front drive rollers rotate which, through the action of the pulleys, causes the threaded rod to rotate. This causes the blade to move along the threads of the threaded rod. This movement effects the cutting blade to move across the width of the graphic tape causing a resulting length of graphic tape being cut at an oblique angle. By disengaging the pulley arrangement, the blade can be positioned in a fixed location along the length of the threaded rod which will result in a straight cut along the length of the graphic tape.

  • Patent number: 4941378
    Abstract: A continuously fed tube is momentarily halted at a cutting station and quickly cut by a rotating knife. The tube is continuously advanced from driving rollers to idler rollers and passes through interemdiate pinch rollers which are cam controlled in synchronism with the cutting process to bow the tube at a rate which causes the tube portion at the cutting station to briefly stop during cutting. The cutter includes a planetary gear set having a carrier rotatable about a central axis which carries a knife for rotation about another axis while it revolves about the central axis. The knife makes many rotations per carrier revolution but is in position to cut the tube during one of the rotations.

  • Patent number: 4771668
    Abstract: An elongated member (20) is fed by a feed conveyor (12) through a cutter (14) which is actuated to cut a first section (21). A takeaway conveyor (16) carries the first section (21) and a second section with a gap between the trailing end of the first section (21) and the leading end of the second section. Detection means (22) located along the takeaway conveyor (16) at a predetermined distance (L) from the cutter (14) actuates the cutter (14) in response to detection of the leading end of the second section providing a second section of a predetermined length (L). Other detection means (42,132) located at other positions along the conveyors (12,16) provide for stopping the apparatus (10) in the event of jamming or after the trailing end of the elongated member (20) reaches the feed conveyor (12).

  • Patent number: 4712458
    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.

  • Patent number: 4428263
    Abstract: A high volume food load slicing machine comprising a pair of loaf feed belt conveyors that continuously advance a food loaf along a downwardly inclined path through a collar into a slicing station at which a rotating and orbiting knife slices the load includes a variable speed knife rotation drive independent of the main drive that orbits the knife and drives the loaf conveyors. A hydrostatic speed variator in the drive connection for the conveyors, with speed corrections made by a stepper motor, affords precision control of slice thickness. A split collar and associated sensor afford continuous sensing of the loaf cross section to provide effective slice thickness correction; the collar is of molded machinable resin so that the knife can cut a working surface on the collar to a precise contour. The collar includes vacuum means to hold the butt end of a loaf for slicing.

  • Patent number: 4419798
    Abstract: An automatic-cutting apparatus arranged to selectively cut a given length of flexible tubing, or ducting, without interruption while the tubing is being produced in a continuous manner. The apparatus comprises a cutting member having a cutting blade, and a wire-cutting tool, both being activated by a combination of electrical and pneumatic elements operated in a sequential manner, to cause the blade to engage and cut the shell or skin wall of the tubing, a sensing arm being provided to subsequently cause the wire-cutting tool to be activated so as to cut the reinforcing wire of the flexible tubing as the tube is being continuously formed.

  • Patent number: 4285084
    Abstract: A method and apparatus for making split lock washers consists of an automated machine wherein the diameter and gap of a lock washer can be accurately controlled. The apparatus includes a drive mechanism for driving the cutter and a transmission unit driven by the drive mechanism which can be adjusted to correlate the feed speed of the wire with the cutter to produce washers of different diameters. After the correlation speed has been set the production speed can be increased or decreased and the synchronized relation of the feed and cutter speeds will remain the same.

  • Patent number: 3974725
    Abstract: A machine for cutting or slicing celery, carrots, or other elongate vegetables into pieces of selected size, accomplished on a rapid and highly economical basis. My machine utilizes a plurality of endless, moving belts, with one of the belts being arranged to receive vegetables deposited thereon, and to transport same to a location adjacent what may be regarded as the terminus of the belt. Mean such as other moving belts are utilized for gradually applying pressure to the vegetables during their travel along the length of the vegetable-supporting belt, thus to accomplish a compression of such vegetables into a tightly compacted mass. High speed cutter means operative adjacent the terminus serve to cut the vegetables into small pieces, with the size of the pieces being determined by the speed of the cutter relative to the velocity of the belts.
