A manufacturing apparatus manufactures flattened tube fins in which cutaway portions for inserting flattened tubes for heat exchanging are formed. The manufacturing apparatus includes: a press apparatus with a mold apparatus that forms the cutaway portions in an unmachined metal thin plate to produce a metal strip; an inter-row slit apparatus cutting the metal strip with the formed cutaway portions into predetermined widths to form metal strips of product width arranged in the width direction; and a cutoff apparatus cutting each metal strip of the product width formed by the inter-row slit apparatus into predetermined lengths. A plurality of box-like magazines whose upper surfaces are open are arranged in the width direction downstream of the cutoff apparatus to stack the flattened tube fins formed by the cutoff apparatus cutting into lengths.

A flattened tube fin manufacturing apparatus includes a press apparatus equipped with a mold apparatus forming cutaway portions into which flattened tubes are inserted to produce metal strips; an inter-row slit apparatus cutting the metal strip, in which the cutaway portions have been formed, into predetermined widths to form a plurality of metal strips of a product width arranged in the width direction; and a cutoff apparatus cutting each metal strip of the product width formed by the inter-row slit apparatus into predetermined lengths. The metal strips of the product width outputted from the inter-row slit apparatus advance into the cutoff apparatus after entering a downwardly sagging state. A support portion that contacts and supports lower surfaces of the metal strips of product width in the downwardly sagging state is also provided.

A continuous strip of T-Nuts formed on a common strip of metal. Each T-Nut of the strip of T-Nuts is integrally connected to the next adjacent T-Nut by carry tabs. The carry tabs can be frangible themselves or contain a frangible portion. Each T-Nut includes a cylindrical bore therein and a threaded interior. A mechanism feeds and severs the endmost T-Nut in endwise fashion. The mechanism to feed and sever the endmost T-Nut includes a cutting blade positioned vertically below the frangible portion of the carry tab. A shearing ram having a guide positioned axially in line with the cylindrical bore in the endmost T-Nut is adapted to move vertically from an upper to a lower position to engage the cutting blade with the frangible portion and sever the endmost T-Nut.

A method of making elongated spacer frame members prevents a first spacer frame member in a series of spacer frame members from being scrapped. A supply of thin relatively narrow sheet metal stock is provided. The stock is fed endwise to a stamping station. The stock is passed through the stamping station that stamps the stock to define a scrap length of stock followed by a connected first spacer frame defining length of stock. The scrap length of stock and the connected first spacer frame defining length of stock are fed to a roll forming station. The scrap length of stock and the connected first spacer frame defining length of stock are formed into a rigid linearly extending scrap element having opposite side walls and a base wall and a connected rigid linearly extending first spacer frame element having opposite side walls and a base wall. A connection between the scrap element and the first spacer frame element is then severed.

A stock supply station for use in a insulated glass unit component production line includes a plurality of rotatable sheet stock coils, an indexing mechanism, and an uncoiling mechanism. The indexing mechanism is coupled to the sheet stock coils for indexing a selected one of the sheet stock coils to an uncoiling position. The uncoiling mechanism selectively uncoils sheet stock from a sheet stock coil indexed to the uncoiling position to thereby provide sheet stock to a downstream processing station.

Weatherstrips (13, 15) having opposed pile sealing elements (226) are installed in opposed slots in a frame member (14) so that the piles may engage opposite sides of a panel, shutter or screen (203), by insertion apparatus having laterally-movable slotted guides (60, 62). The weatherstrips are driven through the slots in the guides by a drive wheel (42). A laterally reciprocating cutter (48) has openings (107, 109), through which the weatherstrips are driven, and shearing edges (98) for cutting ends of the weatherstrips to facilitate entry of the weatherstrips from the slots in the guide into the slots in the frame member. Metering wheel (44) engages at least one of the weatherstrips moving through the guides, and provides for actuation of the cutter, when the desired length of the weatherstrips is driven through the guides; the length corresponding to the length of the frame member which receives the weatherstrips.

A hot forge forming facility includes at least a material supply device, a heating device, a guiding device and a punching device. The material supply device carries a continuous supply of metal material in rolls. The heating device heats and softens the metal material. The guiding device guides and drives the metal material to the heating device. The punching device compresses, forms and cuts the softened metal material in continuous punching operation to smoothly and quickly produce desired products that are consistent with actual production requirements.

The present invention provides a method and apparatus for forming a plurality of parts, such as spade-type boring bits, from a continuous stock material. Thus, the various steps of the forming method of the present invention can be performed to predetermined portions of the continuous stock material prior to separating the continuous stock material into discrete parts, thereby enhancing the efficiency of the forming process. The present invention also provides an improved forge for forming portions of the continuous stock material into parts having a predetermined shape. The forge can be designed to provide a clearance region proximate the forward end of the ram to permit slight flexing of the forward end of the ram in a radially outward direction during forging operations. The forge can also include a lubrication system for lubricating its various components. In addition, the forge can incrementally rotate the ram after one or more parts have been forged. By repeating the incremental rotation of the ram, the forge will eventually rotate the ram a full 360°. An improved forging die is also provided which includes a back surface having a conical medial section and a pair of conical lateral sections that are recessed relative to the medial section such that forces will principally be applied to the medial section during forging operations.

The invention relates to a method for producing bent spring rails from an endless spring band. The method is characterized by the following steps: continuous bending of a section of spring band; cutting the bent section of spring band into a spring rail; discontinuous reverse bending to reduce the internal stresses of the bent, cut-to-length spring rail by subjecting the spring rail to at least one reverse bending force and/or heat-treating the cut-to-length spring rails, the heat treatment being a low-temperature treatment in this case, preferably at a temperature of less than 200 *C.
