Abstract: An edge trimming device is provided for the trimming of moving laminate webs which include a carrier layer and at least one outer layer. A cutting device is supported by a resilient support so that the cutting device is capable of lateral movement while remaining perpendicular to the laminate web. The cutting device trims the edge of the laminate web as it passes by the cutting device. Preferably, the cutting device cuts the outer layer which extends from a longitudinal edge of the carrier layer.

Abstract: Opposed parallel supporting rollers of a log receiving and turning assembly are rotated in order to rotate the log received thereon. The rollers are carried by a frame which is lifted or lowered, as desired, and a bar between the rollers is tiltable so as to lift selectively one end of the log or the other. By such an arrangement, the log is oriented so that a pair of dogs engage the log from opposite ends. These dogs are carried by an overhead carriage assemblies which ride on tracks and are movable with respect to each other by means of a hydraulic cylinder. One dog is rotatable by a motor through 90.degree. so as to orient the log. The carriage assemblies are movable in a longitudinal direction so that a pair of saws, driven by motors, will simultaneously cut the logs on opposite sides so as to deposit the boards, when cut from the log, on respective conveyors which carry the boards longitudinally away from the saws. The saws are adjustable laterally for different widths of log.

Abstract: A base frame mounts a first gang of saws in a common vertical datum plane and a first wood member conveyor device. A second gang of saws in a common vertical datum plane and a second wood member conveyor device are mounted on a carriage on the base frame for movement toward and away from the first gang of saws and first conveyor device. Each saw in each gang is independently vertically adjustable in its vertical datum plane and each saw is rotatable a full 180 degrees around the axis of a chord on the saw blade lying in the common datum plane of such saw. Each saw, during its angular rotation, is precisely supported on a double pantograph movement linkage which follows an arcuate track centered on said chord and vertical datum plane. A precision drive for the wood member conveyor devices and carriage obviates the necessity for a long torque shaft and enables much greater versatility of operation of the apparatus.

Abstract: An apparatus for the longitudinal cutting of webs of material into individual strips has a plurality of cutter pairs consisting of a lower cutter and an upper cutter and disposed side by side. The spreading of the material on its width and the spreading apart of the strips of material after cutting is brought about solely by the mounting of the cutter pairs in an arc along the direction perpendicular to the direction of travel of the web and by the tilting movement of the cutter pairs into the plane of movement of the web of material.

Abstract: An arbor slitter for use in a slitting line, the arbor slitter having at least two pairs of cooperating, blade-carrying arbors. The inboard ends of the arbors of each arbor pair are supported by an inboard bearing housing. The inboard bearing housings of the arbor pairs are mounted on a common base having caster means resting upon a smooth upper surface of a portion of the slitter frame. The base by virtue of its caster means is both shiftable and positionable along this upper surface of the slitter frame so that each arbor pair can be shifted between a working position and a set-up position. The slitter frame has an outboard bearing housing movable thereon into and out of engagement with the outboard ends of the arbors of each arbor pair when in the working position.

Abstract: Trimmer apparatus for trimming the edge of an endless belt of felt, fabric, or other similar material. The apparatus provides quick-release pins for easy removal of the cutting apparatus from the mounting brackets. The mounting brackets are adjustable in both the vertical and horizontal direction to provide the desired knife orientation. A mounting bracket angle retainer maintains the mounting brackets in a perpendicular relationship to one another while still permitting both folding and adjustment of the mounting brackets.

Abstract: An adjustable edge trimmer for removing the marginal excess of rubber from a longitudinally moving sheet of elastomeric material. The edge trimmer is biased into contact with the moving fabric and is free to follow the cord edge while maintaining the same cutting pressure in its movement. The cutting angle is independently adjustable irrespective of the transverse slant of the carriage that carries the edge trim cutter.

Abstract: A method and apparatus for processing round logs in which substantially the entire log is utilized to produce a relatively high value wood stock. The outer area of the log is peeled in sheets to square the central area for the formation of planks, beams, boards or the like while the peeled sheets may be dried, graded, cut to size and joined together and glued to form strips of any desired length and width which, in turn, may be glued in layers to form panels or other high value components. A plurality of powered, adjustable peeling knives are arranged in opposed sets to machine the log as it is caused to pass thereby on a conveyor. In one form of the invention the knives are driven to undergo a circular oscillatory motion while a second embodiment discloses a knife drive in which the knives are guided in vibratory movement. A third form of drive permits a drawcut in that the peeling knives are drive in a longitudinal direction relative to their cutting edges.

Abstract: In an apparatus comprising a set of juxtaposed spaced cutting blades for severing a continuously fed web of material into strips, means are provided for pivoting the blades to and fro during the severing operation so as to avoid localized overheating and wear of the cutting edges.

Abstract: An arrangement for severing webs, particularly fabrics, of thermally severable materials includes a severing tool which is mounted on a support for displacement between an extended position and a retracted position thereof, being urged towards its extended position. The severing tool has a severing portion which is heated and which contacts and severs the web during the movement of the latter longitudinally of itself in a path past the support for the severing tool. A heat-conductive member is in heat-transmitting contact with the severing tool at the severing portion thereof in the extended position of the severing tool, the heat-transmitting relationship being interrupted when the resistance of the web to the severing action of the severing portion achieves such a value that the severing tool is displaced from its extended position toward its retracted position.

Abstract: An edging system for machining the opposed rough edges of a workpiece into a parallelogram having the optimum angle of cut has an upstream sensing station to detect the maximum available width in order to remove the least amount of material. At the edging station a pair of laterally adjustable opposed cutter heads are mounted on a rotatable frame so as to have both the lateral distance between cutter heads and the angle the cutter heads make with respect to the top and bottom surfaces of the workpieces variable. Suitable conveying surfaces transport the workpiece into, through, and away from the edging station.

Abstract: A machine for stripping automatically the sheath from metal cored cables comprises a pair of driving wheels for feeding the cable to be stripped through a nip between the wheels, one of the driving wheels having a fixed axis and the other driving wheel being movable linearly towards and away from the wheel with the fixed axis and being biassed towards it, and a pair of opposed cutting wheels each having a peripheral cutting edge projecting into the region of the nip substantially midway between the driving wheels so that, as the cable is fed through the nip, the sheath of the cable is slit by the cutting wheels continuously along the length of the cable on opposite sides of the cable to enable the sheath to separate from the core, the cutting wheels being linked to the movable driving wheel in such a way that when the movable driving wheel is displaced towards or away from the fixed driving wheel, the cutting wheels are simultaneously displaced in the same direction but through half the distance moved by the
