Abstract: The cushion back carpet cutting tool is a hand tool for cutting foam back carpeting that creates a clean straight cut through the carpeting so that a smooth unnoticeable seam results where two pieces of carpet material are brought together. The tool includes a leading edge on the center plate that opens the adjacent rows of tufts in the carpeting, three blades for cutting the carpeting between adjacent rows either close to the right row of tufts, left row of tufts or midway between the tufts, three plates that retain the blades and an adjustable retainer system for the blades, and a handle. The leading edge has an angle of less than 90 degrees from the horizontal and is rounded in shape to prevent loop or woven carpeting from catching on the tool, and also to keep the tool from jumping out of the row where the cut is being made. The blades are kept in place at an angle of between 15 to 25 degrees from the bottom edge of the tool, which results in a smoother cut being made in the carpeting.
Abstract: The present invention relates to an oscillating assembly for pivoting a blanking die that is constructed and arranged to cut blanks from sheet material. The oscillating assembly comprises a die supporting structure that pivots about a pivot axis. The die supporting structure receives and supports the die such that the sheet material can be fed into the die in a feeding direction and such that the pivoting of the die supporting structure pivots the die relative to the sheet material. A reversible rotary driving assembly rotates a rotatable output shaft in opposing first and second rotational directions. A linearly movable die driver is operatively connected to the output shaft such that (a) rotating the shaft in the first rotational direction thereof moves the die driver generally linearly in a first die driving direction and (b) rotating the shaft in the second rotational direction thereof moves the die driver generally linearly in a second die driving direction opposite the first die driving direction.
Abstract: At a cut end portion of a belt-like member is formed a jointing surface, which is inclined at a small angle with respect to the surface of the belt-like member, simultaneously with cutting. A belt-like member (32) on a conveyor belt (6) is pinched under a pressure by an upper die (29) and a lower die (33) heated respectively by heaters (30) and (34), thereby it is subjected to plastic deformation and cut, and also jointing inclined surfaces are formed at the cut end portions. A die holding member (24) for holding the upper die is reciprocated in the vertical direction, by an action of a rotary shaft (11) having an eccentric cam (18). A separating member (38) which is moved vertically by another cam (40) operates as delayed with respect to the movement of the upper die, and when the upper die leaves the belt-like member, it presses the belt-like member to insure separation of the die.
Abstract: A cutting assembly for cutting a continuous sheet of material covering containers which are continuously conveyed in spaced apart container carriers in a predetermined direction at a predetermined speed. The cutting assembly includes a support assembly and a mechanism coupled to the support assembly for rotating the support assembly in an orbital path so that the support assembly passes above the container carriers at substantially the predetermined speed and direction during a first portion of the orbital path. The cutting assembly also includes a blade assembly pivotably coupled to the support assembly for cutting the continuous sheet of material as the support assembly moves above the container carriers during the first portion of the orbital path. The cutting assembly further includes an alignment pin for aligning the blade assembly with respect to the container carriers as the blade assembly cuts the sheet of material.
Abstract: A clipper for cutting wood or plywood veneer transversely and other similar continuous sheet materials is described which ensures that the sheet material is cut in alignment and the cut achieves a square edge on the material. The clipper includes at least a pair of guillotine knife blades, each blade extending transverse to the sheet material, each blade cutting against a single anvil cylinder rotating in synchronization with the sheet speed. Each blade is preferably mounted in an actuating assembly which includes a crankshaft and a connecting rod. The blade is journaled to the crank of the connecting rod at its lower portion. The upper end of the connecting rod is guided along a radial line with respect to the center line of the anvil. Upon turning the crankshaft, the blade advances simultaneously vertically and horizontally into contact with the veneer. The imparted motion is such that the blade always remains substantially perpendicular to the surface of the veneer being cut.
Abstract: There has been provided a cutting device utilizing a fixed cutting edge and a movable roller axially mounted on a radial arm parallel to the cutting edge. The roller has an outer surface which is also parallel to the cutting edge. A composite laminate for making peelable labels is moveably supported between feed and take up rolls in parallel spaced relation with the roller and the cutting edge. The radial arm is actuated for moving the roller against one side of the composite and urging an opposite side thereof against the cutting edge for effecting the cut as the roller moves in proximate spaced relation with the cutting edge. The radial arm and roller carried thereby swings between extreme stop positions, and a cut is made each time the roller swings in proximate spaced relation to the cutting edge. The frequency of the swings of the radial arm, or the speed of the composite past the blade determines the length or distance between the cuts.
Abstract: The invention discloses an edger having at least one edging means (7). For displacement of the edging means substantially perpendicularly to the feeding direction of a board to be edged at least one pendulum arm (27) is provided which is swingably about a substantially vertical position and is journalled around an axis (25) parallel to the feeding direction and located underneath the feeding plane (16). In its upper end the pendulum arm carries the edging means (7) and its driving means (34,35).

Abstract: Steel bars are continuously fed along a path in a direction transverse to the bar axes, are separated by a separator and are then supplied by a roller conveyor to an axial interval regulating station. From this station each steel bar is supplied in the axial direction at regular intervals by means of sets of pinch rollers which are provided at specific intervals and which can be separately dislocated out of the path of movement of the bars and by means of a rod and a spacer fitted to the tip of a swing rod pivotally connected to the rod. Steel bars are thus delivered at regular intervals to a coating station and thereat have the entire lengths thereof, except the threaded end portions thereof, coated with a coating layer. Thereafter, the coated bars are sent to a taping station, whereat the entire lengths of the bars, including the coating layers, are tightly wrapped by a thermo-shrinking tape.
Abstract: A dispenser for cards which are withdrawn by customers at the entrance of a parking lot has a housing for a supply of coherent cards which are transported seriatim by advancing rolls toward an outlet opening for withdrawal by customers. On its way toward the outlet opening, each card is provided with legible information by a matrix printer which can apply such information in response to a signal from a computer while the card is in motion. The thus imprinted card then advances between the matrix and the perforating tool of a punching apparatus which applies one or more holes while the card is in motion. The matrix and the tool are mounted on a plate which is secured to a fixed bracket by a first parallel motion mechanism so that it can move in and counter to the direction of movement of the card between the tool and the martrix. The plate is pivotable about a fixed axis by an oscillating crank gear so that the tool moves along an arcuate path to which the adjacent card is tangential.
