Abstract: This invention relates with the method for manufacturing frames from aluminum profile rails, which undergo a series of cuts and perforations, done with a mechanism formed by two sections, an upper section which is made up of an upper plate to which a determined number of perforating bolts and knives are attached perpendicularly and a lower plate to which a determined number of blocks with different designs on their faces are affixed, resulting, as a consequence, a number of cavities into some of which aluminum profile rails will be inserted for cutting and perforation; and in others the perforating bolts and knives will penetrate making the cuts on the profile rails possible. Both sections are mounted on a support which by way of removable legs (preferable a tripod) can be positioned for operation.

Abstract: An apparatus for forming an element-free gap in a continuous slide fastener chain. In the apparatus, a reciprocating punch blade has cutting edges along opposite sides and is relieved at opposite ends along the cutting edges so as to form a pair of wing portions disposed one on each side of the punch blade. An elongated slot formed in a die for receiving the cutting edges has at its opposite ends a pair of lateral branches disposed one on each side of the elongated slot in opposite relation to the sides of the punch blade on which the wing portions are disposed. The wing portions and the lateral branches jointly serve to protect a pair of coupling elements disposed adjacent to the opposite ends of the space section from being cut by the punch blade.

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.

Abstract: A predetermined volume of the face part of a segment of boneless fresh whole-muscle meat (e.g. strip loin, tenderloin, top sirloin butt, or ribeye roll) is positioned in engagement with a stop plate and constrained in a first shaping clamp of given cross-sectional configuration and thickness, and an additional part of the meat segment is constrained in a second shaping clamp of approximately the same cross-sectional configuration, with both shaping clamps solidly filled; cutting the meat segment between the two shaping clamps forms a steak or other meat portion of closely controlled volume and weight.

Abstract: For use with any type of saw and base such as a miter saw which can be set as to angle, the present apparatus comprises a pair of profile members corresponding to different sizes and shapes of conventional mold and such profile members may be supported at a proper angle on the flat bed of a table, such as a miter saw table, so that the piece of mold being cut is placed in a proper face-to-face profile engagement position with the profile member and thereby held in the proper angle and the proper position to be cut exactly in the manner as the mold will occupy when installed on a ceiling or other place. The method is the procedure for positioning the profile member in place, holding same in position, placing the mold to be cut in face-to-face relationship coextensively against the profile member, and cutting same. According to this, two pieces of mold will be cut on each end of each piece so that the matching cuts will fit exactly when installed in place.

Abstract: Apparatus for subdividing a web of wrapping material into sections of predetermined length has a reciprocable carriage for a pair of grippers which are pivotable into engagement with the web to thereby clamp the web against the carriage while the latter moves forwardly. This advances the web through a distance which approximates but is less than the distance necessary to advance the web by the length of a section. The grippers are thereupon disengaged from the web while the carriage continues to move forwardly, and the web is braked by one or more brushes so that two pawls whose pallets are biased against the web can catch up with a pair of marginal notches in the web. The pallets enter the respective marginal notches and complete the forward movement of the web. A mobile knife cooperates with a stationary knife to sever the web and to thus separate a section from the leader of the web while the carriage moves rearwardly.

Abstract: An apparatus for simultaneously cutting wire segments having acutely angled ends from a plurality of wires including guide apparatus and feeding apparatus for the wires, and a cutting device comprising a base, reciprocable shear plate and clamp plate, each of which has parallel grooves therein, with each also having sliding surfaces that are at an acute angle to the axis of the grooves. A collection plate is also provided to contain cut segments and transfer the segments to a common collection point.

Abstract: The present apparatus applies force along a line or to a surface through one or more linear or rather longitudinal, elastically expandable or deformable members. The expansion of the elongated member, such as an elastic, reinforced hose or membrane, is transmitted to the tool proper, for example, a strip steel knife or a clamping device, along the entire length of the tool, whereby a linear force application is achieved. Several of such members may be arranged in parallel to obtain substantially a surface area force application. The force application member may also be curved for applying the force, such as a cutting force to an equally curved tool such as a strip steel knife. The force application member is returned to its starting position after a work stroke is completed. The work stroke is performed by expanding the member with the aid of a medium under pressure. The return is accomplished by a spring force or by a similar expansion member.

Abstract: Apparatus for holding the head of an animal severed from its body for use in cutting the edible portions from the bones. The head is clamped between first and second members rotatably about a common axis and displaceable towards each other. The snout is received in the appropriately configured first member and a prong of the second member penetrates into the foramen magnum in the occipital bone. The rotation of the first and second members may be braked or arrested by a friction brake. To move the lower jaw away from the upper jaw in order to remove the lower jaw a hook member engaged the lower jaw and pulls it open by means of a foot-operated piston-and-cylinder unit. Another piston-and-cylinder unit forcibly drives the first and second members toward each other to firmly clamp the head therebetween.

Abstract: A method is provided for fabricating a slide fastener chain having a certain length and reinforcement tapes at its ends from a manufactured, continuous length fastener chain which is provided with space sections each of which entirely consists of a reinforced tape. According to the method, the original length fastener chain is held first by a pair of pressers on a die at one side of the main crosswise cutting line, then by another pair of pressers at the other side to form a right position so that the reinforced space section is cut along the crosswise line and at the same time, the lengthwise lines by a cutter blade. This method is performed using an apparatus with a linkage motion of its individual parts whereby working efficiency is improved and a good cutting finish is obtained.

Abstract: A sheet gripper for a sheet-displacing apparatus such as a rotary printing machine has a pair of gripper elements whose faces are engageable with each other to grip the edge of a sheet being printed. At least one of the gripper elements is formed at its respective face of a relatively soft elastomeric material from whose surface extend hard fibers which are otherwise imbedded in the soft elastomeric material. The material may be a thermoplastic synthetic resin reinforced with glass fibers.

Abstract: The present trimming apparatus is capable of trimming the margins of three-dimensional workpieces with the aid of strip steel knives which are driven, preferably by pneumatic piston cylinder means in any desired direction. The workpiece such as the dashboard of a car, is held on the outside thereof by a workpiece support which has such a shape and cut-outs that the strip steel knives may be moved through the workpiece support. A counter-holder presses the workpiece against the outer support. In this combination of elements the workpiece may be trimmed from any direction from its outer side inwardly. The trimming tools may be operable in sequence and may also be supported on a carriage which shuttles back and forth between a trimming station and a loading and unloading station. Power savings may be in the order of 90% as compared to the power requirements of conventional stamping tools.

Abstract: A hydraulic cylinder mounted on a frame assembly is communicated with a hand operated pump for actuation thereby. A plurality of punch-die assemblies, to be selectively mounted in the frame assembly for perforating, notching clipping or like operations, each comprise a punch or punches carried by a punch holder constrained to up-and-down motion relative to a die. When placed in the frame assembly, any selected punch-die assembly has its punch holder disposed under a ram connected to the piston of the hydraulic cylinder, so that upon manual activation of the pump, the punch or punches can be forced down to perform a desired operation in cooperation with the die. The punch and die assembly has a presser which urges the workpiece against a lateral side of the punch, and the workpiece can be acted upon at two locations at the same time, one location being directly above the other.

Abstract: This invention relates to a novel apparatus for cutting mats of compressible insulation materials arranged in stacks into small intricately shaped pieces which comprises an elevatable platform which raises the stack and compresses same against the undersurface of a rigid pattern supported in spaced relation beneath an overhead framework on uprights which are rotatable and include an offset portion sized and positioned to receive that part of the fabric cutter overhanging the axis of upright rotation regardless of the position of the cutter adjacent the edge of the pattern.

Abstract: An automatic BX cable cutter including a cable guide and clamp, a circular saw carried by a floating pivoted carriage actuated between cutting and inactive positions by a cam, the machine being so electrically coordinated that, when the saw motor is started and the cable end is inserted into its guide to a pre-set stop point, the clamp screw moves to cable-holding position, and the feed motor permits the carriage and saw to be raised to cutting position; after the cut has been made, the saw is retracted, the clamp screw drive is reversed and the cable is released.

Abstract: A carriage assembly for automatic face up one way spreading of multiple plys of fabric or any other web-like material of a predetermined length, which is automated to operate in a continuous manner in the absence of operator manipulation at the termination of each fabric spreading cycle. The device incorporates a fabric or web-cutting assembly normally enclosing a transversely traveling severing blade and means for automatically engaging the free end of the fabric after sequenced severing so as to maintain the fabric in a fixed relation relative to the assembly during return or non-spreading carriage motion thereby preventing disturbance or change of position of the free end of the fabric as caused by carriage motion airflow, so that upon automatic recommencement of spreading, the end of the fabric will be deposited at a predetermined position on the spreading surface which will be accurately repeated for each subsequent automatically deposited ply of fabric, thereby providing maximum fabric utilization.

Abstract: A chop saw for selectively cutting logs to various lengths includes a motor-driven circular saw blade mounted at the outer end of a saw carriage pivoted to a fixed base. A rotary crank mechanism driven by a hydraulic motor on the carriage oscillates the carriage about its pivot to feed the saw blade into and out of a log held in cutting position alongside the carriage by hydraulic cylinder-operated clamp arms which are also mounted on the fixed base. A crankshaft of the rotary crank mechanism carries a cam which operates a hydraulic flow control valve in the hydraulic circuit of the carriage drive motor to reduce the speed of the motor and thus carriage travel only when the saw blade cuts through the log. Limit switches in an electrical control circuit and operated by cams on the crankshaft control the operation of valves in hydraulic circuits for the clamp cylinders and carriage drive motor to coordinate the positions of the carriage with the closing and opening of the clamp arms.

Abstract: A paper knife is mounted at its opposite ends on a pair of arcuate arms pivotally attached to the knife table. The knife is operated by a fluid cylinder which extends from the table to the knife. This way all of the operating apparatus is positioned beneath and not above the table, thereby providing a low profile so that the operator may reach over the knife. Various mechanical details enable quick paper sets and closer cuts.
