Abstract: A paper cutting device, for cutting multiple sheets of paper stacked in layers on a table, comprises a paper retainer (2) descending from an upper side along a guide and a cutter (3) diagonally ascending from the lower side. A receiving part (18) is mounted on the lower surface of a paper retaining frame (20). The receiving part (18) is formed by joining a base plate (36) with a large elastic modulus such as a metal to a resin receiving plate (37). A slip prevention structure is installed on the junction surfaces of the base plate (36) and the receiving plate (37) to suppress the extension/retraction of the receiving part of the paper retainer so as to prevent wrinkles from occurring in the paper near a blade receiving surface when the paper is cut off.
Abstract: A sheet cutting apparatus includes: a cutting blade for cutting an edge of a sheet bundle conveyed to a cutting position of the sheet bundle; a cutting blade moving section for moving obliquely the cutting blade with respect to a sheet surface of the sheet bundle; a fixed supporting table for supporting the sheet bundle in a vicinity of the cutting position; a blade receiving member for pressing the sheet bundle and receiving the cutting blade in the vicinity of the cutting position; and a blade receiving member moving section for ascending or descending the blade receiving member. A center position of a load application action of the blade receiving member by the blade receiving member moving section, is set to a position upstream of the sheet cutting position in a conveying direction of the sheet bundle, and in the vicinity of the sheet cutting position.

Abstract: A post treatment process of a seamed belt for providing a smooth surface and substantially eliminating protrusions by using a planing blade, and a seamed belt that has undergone the post treatment.
Abstract: Products (2) made of paper or similar materials are cut along predetermined cutting lines in a drawing cut between crossed knife edges while being conveyed continuously in a dense conveying stream in which their main surfaces are orientated substantially perpendicular to the conveying direction (v). For this purpose a counter knife (1) with a guide edge (11) is allocated to each product (2) and the products (2) together with the counter knives (1) are conveyed past at least one cutting knife (5) with a cutting edge (51) having two ends, whereby the cutting edge (51) of the cutting knife (5) substantially lies in the plain formed by the guide edges (11) of the counter knives (1) and forms a cutting angle (.alpha.) with the guide edges (11).
Abstract: Apparatus and method for removing fibrous material wound around a generally cylindrical shaft rotated about a central longitudinal axis thereof. A cutter blade is provided to have a forward edge portion extending along the central longitudinal axis of the shaft, which edge portion is normally spaced from the shaft to define a non-cutting position. The edge portion of the cutter blade is moved about a reciprocating locus defined by a forward movement from the non-cutting position to a predetermined distance from the shaft effective to define a cutting position contacting the fibrous material, a lateral movement in the cutting position along the central longitudinal axis of the shaft to cut the fibrous material for its removal from the shaft, and a rearward movement from the shaft to return the edge portion to the non-cutting position.
Abstract: A cutting device for cutting a block of tobacco includes a rotatable support and guide structure mounted for rotation about an axis disposed at an angle to the direction of advance of the block of tobacco. A plurality of movable blade carrier elements are mounted on the support guide structure with each element carrying a cutting blade adapted to intersect and penetrate the block of tobacco. Each carrier element is axially movable independently of the other carrier elements and is pressed against a stationary cam member by a thrust member. Upon rotation of the support and guide structure, each blade carrier reciprocates in response due to engagement with the cam member.
Abstract: A cut-off machine especially suitable for handling tubing and including a machine frame defining a work treatment area, a ram on the frame adjacent the work treatment area mounted for movement through a power stroke by at least two drive members engaging the ram at spaced points, a motor system mounted on the frame, and a drive system interconnecting the motor system and the drive members on the ram. The drive system comprises a pair of flywheels driven by the motor system, a pair of crank shafts driven by the flywheels through a clutch associated with each flywheel, and a crank portion on each crank shaft journalled in the ram so that the ram is moved through an orbital path in response to rotation of the crank shafts. A gear train is positioned between the crank shafts to synchronize the rotation of the crank shafts to ensure that the ram moves in a translatory manner through its orbital path.
Abstract: Disclosed is a handle adapted for grasping by the hand of an operator for operating a pivotable machine part, comprising a thumb supporting member attached to the machine part for supporting the operator's thumb and a grip part connected to the machine part for gripping by the rest of the fingers of the operator's hand. Also disclosed is a microtome embodying this handle.

Abstract: Apparatus for trimming the front, head and foot ends of brochures has a stationary platform which supports one brochure at a time. A first knife which trims the front end of the brochure on the platform descends in a vertical plane ahead of two additional knives which thereupon simultaneously trim the head and foot ends of the same brochure as soon as the first knife completes the trimming of the front end. The first knife is pivoted forwardly and away from the additional knives while the additional knives move toward and trim the brochure on the platform. This insures that the first knife is held out of the way while the additional knives move to positions in which their forward ends extend beyond the trimmed front end of the brochure.
Abstract: The specification discloses a hydraulic pressure operated hand tool of the type in which the manual pressure exerted on a small-area pump piston creates a hydraulic pressure which is communicated to a power cylinder for activating a hand tool jaw member, such as a cutter blade. Preliminary take-up movement of the cutter blade into contact with the object to be severed, such as cables, pipe etc., is effected by manual pressure applied to a second pump piston of relatively large area, which causes rapid displacement of the hydraulic medium from a reservoir to the power cylinder before exertion of manual pressure to the small-area pump piston. A release valve provides instant return displacement of hydraulic medium via a by-pass communication from the cylinder to the reservoir to relieve the activating pressure on the cutter blade and restore it promptly to normal position. Interchangeable cutters are provided.
Abstract: A spiral cutting anvil is provided with indicia along its length, and a series of aligned gaps through which a cutting blade can be passed. A cutting blade comprises the working portion of a cutter assembly pivotally fastened to a slide plate which can be located at various positions with respect to the anvil. An adjustable stop is disposed at an appropriate point along the spiral, as determined by the indicia, and a length of packing material extends from the stop along the anvil to one of the gaps. The cutting blade is then urged through the gap, in guillotine fashion, to sever the packing at the correct point.

Abstract: An automatic capacitor winding machine has a retractable bifurcated arbor and vertically movable clamps to grasp the ends of the capacitor dielectric layers and carry those ends to a point below the retracted arbor. The bifurcated arbor is registered in its retracted state with its slot parallel to the dielectric layers. The arbor is then extended and grasps the dielectric layers between its tangs. The pressure grasping the dielectric layers is partially removed to allow the arbor to rotate and pull the dielectric layers from between the clamps. A stripper washer is provided to freely rotate on the arbor with limited movement parallel to the axis of the arbor and with a relatively small clearance between the washer's inside surface and the arbor's outside surface. Photoelectric means are provided to accurately detect the location of the first tab (terminal) to time the insertion of the other tabs. A reciprocating blade severs the dielectric layers after the capacitor is wound.
