Abstract: A device for use in applying panels to a wall, for providing holes in the panels to expose electrical outlets and switches therethrough. The device includes two components, a box and a cutter plate; the box is fitted to an outlet or switch, that is in position in the wall, and has pins and a peripheral cutting edge directed outwardly when the box is so fitted. The wall panel to be put on the wall is tentatively set in place, bearing against the pins, and is then tapped to drive the pins into and through the panel. The panel is then removed from such tentative position, carrying the box with it, by means of the pins friction-holding in the holes, and laid on the floor with the box down. The cutter plate is then fitted on the pins which are exposed through the panel, applied to the upper surface of the panel, and struck with a hammer, forcing the panel against the peripheral cutting edge of the box, cutting through the panel and leaving a hole therein of the size, shape and location of the box.

A rotary encoder mounted on the carriage assembly has a pinion which engages a rack carried by the conveyor to detect movement of the carriage assembly relative to the conveyor when the carriage assembly returns to its starting position after completing its cutting cycle.
Abstract: Prior to the forming of bar material, without creating internal stresses, on transverse transport presses, bars are sub-divided into sections of equal volume, the end-pieces of each bar having to be discarded before further processing. To provide for the automatic and material-saving discarding of the end pieces, two light barriers are installed in the feed zone of the bars, the distance (a) between these light barriers being newly stored in a microprocessor as each bar is fed in, and this distance being converted, by calculation, to three further distances (b, c, d). By reference to these data, the microprocessor controls the discarding operation, with one, or at the most two, section lengths being discarded per bar, according to whether the interface between two successive bars is located in the central region of the section length in question, or in one of its two end-regions.
Abstract: A system for cutting generally planar quadrilateral workpieces into a plurality of quadrilateral elements, at least a portion of which have both their length and width dimensions smaller than the overall length and width dimensions of the original workpiece wherein cuts extending completely across the workpiece parallel to one of the length and the width dimensions thereof are first effected by a first saw with the cut pieces being then conveyed to a third saw where cuts completely thereacross may be made in directions perpendicular to the one dimension. The remainder of the workpiece is conveyed to a second saw where cuts are made in directions parallel to the other of the length and width dimensions with the cut portions of the workpiece remainder being subsequently conveyed to the third saw for effecting cuts in the cut portions in directions parallel to the one dimension.

Abstract: An arrangement for fabricating planar elements which may be stacked for producing predetermined surfaces and bodies. The planar elements have cross-sections corresponding to respective cross-sections of the surface to be constructed. The planar elements are formed by cutting them from plate-shaped material or sheet metal, and the cut-out elements are held to the parent sheet or plate material by tabs. The planar elements are cut successively from the sheet or plate-shaped material at spaced intervals. The cutting action is such as to leave the tabs for holding the planar elements in place. Registration holes are punched about the planar element, so that these may be readily stacked relative to each other, as required to form the surface to be constructed. Sprocket holes are also punched in the sheet material to advance the material along a processing path at which the various processing stations are located.
Abstract: Three-dimensional work pieces, such as instrument panels or dashboards, are made of initially flat stock or of synthetic material such as a two-component foamable material. The tools of the present apparatus include upper and lower holding tools which are preferably simultaneously shaping tools, and cutting or trimming tools. The upper tools and the cutting or trimming tools may have a common support which is preferably exchangeably secured in a main frame. The shaping tools are moved into a first cooperating position relative to each other, whereby the work piece is formed into the desired shape. The shaping tools may then be locked in the shaping position or they may be moved into a second cooperating position to be rigidly locked in the second position. A tool support such as a table carried by a scissors lift frame is used for moving the shaping tools into the desired positions. The cutting or trimming is then performed by applying pressure to the respective tools.
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.

By means of the method according to the invention, in order to obtain a reduced width for the open end of the slots, the two edges of the slots are produced in two separate operations, namely a first cutting operation in the course of which one of these edges is first formed and then a second cutting operation in the course of which the other edge is formed.
Abstract: Sod is removed from the field in standard width strips and the strips are cut into equal length sections. Excess moisture, when present, is removed from the sod prior to delivering the sod sections to an apparatus which removes excess soil from the bottom of the sod to reduce weight and form a product of uniform thickness. The sod sections are then delivered soil side up to a scoring and trimming apparatus which trims each section to an accurate length and scores the sod partly through the root structure longitudinally and transversely to form a plurality of equally-sized rectangular plugs in each sod section which can be easily separated by a user. Prior to the second scoring operation, pairs of sod sections are placed on moisture-absorbing trays and following the second scoring, plural layers of processed sod sections and intervening trays are placed in superposed relation in a shipping carton having a moisture-impermeable liner.
Abstract: Successive pouches are formed from a web of plastic film by advancing the web through a folding station and folding the web along a longitudinal fold line to form a two-ply portion and a single ply portion adjacent thereto. At a sealing station, confronting surfaces of the two-ply folded portion of the web are sealed together along longitudinally spaced apart seal areas extending transversely across the two-ply portion to define a series of successive pouches interconnected by the seal areas. At a flap forming station predetermined waste areas are severed and removed from the single ply portion of the web to form the same into a series of successive flaps extending alongside each of the pouches and adapted for being folded over the pouches to close the same.
Abstract: Method for treating bands of heated non-vulcanized rubber for handling upon removal from a rolling mill which includes the formation of a web of material, and the severing of the web along lines parallel to the web axis to form processing strips. The web is initially formed having a width substantially equal to an integral multiple of process strips, and thereafter the web is partially slit longitudinally along a substantial portion only of the length to provide a plurality of strips, each of the strips being coupled together across a transverse header arranged integral with each of the strips for facilitating handling. The technique is particularly adapted for treatment of the heated non-vulcanized rubber prior to the passing of the material through a cooling tunnel preparatory to storage.
Abstract: A flexile core material for laminated structures is produced by providing a sheet of rigid elastic foam plastic material having a pair of opposite sides; slotting the sheet from one side to form a plurality of longitudinally extending, contiguous, strips of equal width, said strips being articulately interconnected by hinge pieces constituted by unslotted portions of the sheet on the other side thereof, said unslotted portions being longitudinally spaced at equal intervals, and slotting the sheet transversely from one side to divide said strips into rectangular block-like elements of equal length, said elements being separated from one another save at said hinge connections.
Abstract: Battery grid plate castings are trimmed in a two-step operation. Each plate moves flat along a horizontal or inclined path against a first stop bar. One of two trim blades on a reciprocating upper die block then shears flashing from the leading end of the plate during a downward stroke of the die. Then the stop bar raises during the upward stroke of the die, and the plate moves forwardly against a second stop. Upon the next downward die stroke the second trim blade shears flashing from the trailing edge of the plate. During the next upward stroke, the fully trimmed plate moves forwardly onto a stacking device. As the leading end of one plate is trimmed at the first trim station, the trailing end of a preceding plate is trimmed at the second trim station. The second stop is easily moved to different stop positions along the path of travel of the plates to change the distance between such stop and the second trim blade and thereby enable trimming plates of different lengths without changing dies.
