Abstract: A gear drive system for a printer designed to print upon a continuous roll of paper and having a blade used to cut off printed portions of paper from the paper roll is implemented. The gear drive system consists of a drive shaft 330, a slip clutch 401, a clutch gear 116, a drive gear 110, and a staggered gear 112 which controls the paper cutter blade 106. During printing, clutch 401 allows the drive shaft 330 shaft to slip relative to the clutch gear 116. When printing stops, clutch 401 locks clutch gear 116 which is engaged with the first portion of staggered gear 112 and causes staggered gear 112 to rotate until the second portion of staggered gear 112 engages the drive gear 110. Staggered gear 112 is then driven by the drive gear 110. A cutter blade is controlled by staggered gear 112, with the blade cutting off the paper as the drive gear 110 is in reverse rotation.

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.

Abstract: A saw assembly for a grip-harvester has a saw chain running around a bar and a chain sprocket; a bar holder pivotably journalled on the saw assembly stand; a saw motor driving the chain sprocket; and a device for feeding a bar out and in. The feeding-out and feeding-in device preferably is a hydraulic cylinder mounted on the stand and having a piston rod. The movements of the piston rod are transmitted to the pivotable bar holder by means of a pivotably journalled first toothed wheel which is joined to the bar holder and has a toothed wheel rim cooperating with the piston rod which is in the form of a rack. The saw assembly is also provided with a device for sensing and recording the angular position of the saw bar in relation to an initial position, which device has a smaller second toothed wheel in engagement with the first larger toothed wheel of the feeding-out and feeding-in device, and also at least one sensor which senses a tooth gap or a tooth on the second toothed wheel.

Abstract: A tape end trimming apparatus for appropriately cutting and shaping the ends of plural tapes of different widths without wasting the tape and without requiring replacement of the cutting blade is provided. The tape end trimming apparatus comprises cutting for trimming the corners of the end member of a tape. A guide member comprises tape insertion path for guiding an inserted tape to the cutting apparatus. An end position regulator regulates the insertion position of the tape end. The cutting apparatus comprises cutting blade for cutting the end corners at the sides of tape with the position of one side thereof regulated by one tape side position regulator and the position of the end thereof regulated by end position regulator, and the position of the other side thereof regulated by the other tape side position regulator and the position of the end thereof regulated by end position regulator.

Abstract: An egg case cutting apparatus for use in a refrigerator is disclosed. The apparatus is comprised of a pocket for accommodating the egg case, a guide rail disposed along a longitudinal direction of the pocket, a body being formed with a guide hole through which the guide rail passes, and a cutting member installed in the body. When the body is moved, the edge of the egg case is inserted into the body and is cut by the cutting member. The cut part is discharged outside through a discharge port formed on the body.

Abstract: In a tape cutting mechanism, when a tape is cut manually, a rack 58 which is lowered by pushing a push button 14 down meshes with a gear 48 by guidance of a guide groove 59 to thereby cause a scissors cam 46 to make a single complete rotation along with a pin 46b around a cam shaft 47. The pin 46b half rotates to raise a turnable arm 52b up so that a turnable blade 52a is turned toward a fixed blade 55 to cut a printed tape portion. By the remaining half rotation, the turnable arm 52b is returned to its reference position. When the rack 58 rises with the resiliency of a compression spring 57 due to release of the push button 14 from its pushed state, the rack 58 is disengaged from the gear 48 with the guide of the guide groove 59.

Abstract: A gear drive system for a printer designed to print upon a continuous roll of paper and having a blade used to cut off printed portions of paper from the paper roll is implemented. The gear drive system has a drive gear which slips against a toothless portion of a driven gear while paper is being fed through the printer for printing by a print head. When printing stops, the drive gear reverses its rotation, causing the driven gear to engage the drive gear. A cutter blade is controlled by the driven gear, with the blade cutting off the paper as the drive gear is in reverse rotation. After the paper is cut, the drive gear resumes its forward rotation, rotating the blade away from the paper. After the blade has been rotated, the drive gear continues to turn, but slips on the toothless portion of the driven gear. Friction losses are minimized as the energy lost as friction is low and full torque is applied to both cutting and opening rotations of the cutter blade.

Abstract: Each glass gob is severed by a shear blade pair (6; 9). The shear blades (7, 8; 10, 11) are arranged on shear arms (12, 13) whose movement is synchronized with each other by means of a gear mechanism (16) A first shear arm (12) is drivable pivotably by a drive means (36), while a second shear arm (13) is supported by an air spring (28). The drive means (36) is carried on a carriage (39) which is displaceable by piston-cylinder units (48, 49). The drive means (36) drives a crank pin (43) which is connected by means of a coupling rod (44) with the first shear arm (12). By displacement of the carriage (39) one achieves a servicing stroke (34) which is greater than the working stroke (32) of the shears.

Abstract: A convenient and effective cutter for a cable, a plastic pipe or the like is provided. The cutter includes a base rotatably receiving therein a screw rod having a screw portion and a driving end, an immovable blade having a first curved portion having a first curved knife-edge, and a movable blade having a second curved portion having a second inner curved knife-edge and an outer toothed surface capable of engaging with the screw portion. When the driving end is rotated, the two knife-edges can be set in a relative motion to cut a work piece contained between the curved portions.

Abstract: Apparatus for cutting a conduit or tubular element transversely to the longitudinal axis thereof which includes a base having a housing projecting vertically therefrom. The housing includes opposed, substantially parallel side plates separated by a vertical slot at their upper ends, and by a mechanism chamber at their lower ends. A blade element is pivotally supported between the parallel side plates, and carries a plurality of ratchet teeth along the lower peripheral edge, and a cutting edge disposed at the opposite side of the blade element from the ratchet teeth. Between the teeth and cutting edge, the knife element has an elongated, arcuate slot formed therethrough. An operating handle is pivotally connected to the housing at a side thereof spaced from the pivotal axis of the blade element. A pawl lever is pivotally connected to the operating handle and has a dog thereon positioned to ride over and operatively engage the ratchet teeth as the operating handle is pivoted.

Abstract: A support has portions which define a working plane and an arm is pivotally mounted on this support at one end, and carries a circular saw blade which can be moved toward and away from the working plane as the arm is pivoted. Cooperating mechanical elements are provided on the arm and on the support and are power-driven so as to pivot the arm with the blade towards and away from the working plane. These mechanical elements may be rack and pinion constructions or they may be screw spindle and spindle-nut constructions.
