Abstract: A method an apparatus for forming a trim insert particularly suited for automotive purposes such as a door insert includes a first carrier which holds the substrate and a second carrier which holds a material larger than the substrate. A drive assembly is connected to the first and second carriers to position the first and second carriers. A positioner positions the substrate from the first carrier and together with the substrate of the material on the second carrier.

The second carrier may have a contoured mold to form a desired wrinkle pattern in the material prior to folding the material.

Abstract: A method of forming composite sine wave spars from composite material. In accordance with the method, the sine wave spar is formed of web plies, filler plies, separator plies and cap plies. The edges of the web plies are cut to form a plurality of teeth having different geometric configurations. The web plies are first formed to the sine wave contours of a tool having the desired final part geometry. The teeth of the web plies are then folded over the edges of the tool to form a portion of the flanges of upper and lower U-shaped channels. The portions of the flanges of the U-shaped channels not covered by the teeth are formed using filler plies that intermesh with the teeth to form a layer of the flanges of the respective upper or lower U-shaped channel. The flanges are reinforced through the use of separator plies that are placed between the filler plies. The formed upper and lower U-shaped channels are joined together so that their respective flanges are located in line with each other.

Abstract: Pile weatherstripping having rows of pile and longitudinal fins both within and external to the rows of pile. The heights of the fins with respect to the height of the pile may be independently varied and controlled. A travelling endless band receives a pair of first webs providing internal fins on opposite sides of the band. The first webs are indexed to the edges of the band, which defines the heights of the fins. Each web may be independently indexed. Alignment of the webs on the band is provided either by an aligning fixture or by coining the webs to provide lines of indentations which index the webs at the edges of the band. The yarn which forms the pile is wound around the first webs. Second webs providing the external fins are indexed through the yarn and first webs to the edges of the band and are also aligned by a second aligning fixture or by coining. Backing strips are attached, as by ultrasonic welding, along the edges of the band. Then the yarn is slit without cutting into the webs.

Abstract: A method and apparatus for application of a header label to the bag. The bag, which has previously been filled with a product, is presented to the apparatus at an upstream bag presentation and accepting station and is gripped proximate its top. It is then transferred from the upstream bag accepting station to a downstream bag release station. Before being released, the bag travels to an intermediate label application station where a label is readied and applied to the bag. Thereafter, the bag proceeds downstream, with the label, and the label is sealed to the bag. A series of grippers are employed for accepting a stream of discreet bags in a continuous manner. The grippers are recirculated continuously so that the apparatus operates continuously so long as bags are presented for application of a label.

Abstract: A process for achieving an adhesive bond in a folded joint between a first component (1) and a second component (2), preferably of sheet metal. The components (1,2) have essentially flat edge areas (3,4), and the second component (2) has a bent-up flange (5) to be bent down about the edge area (3) of the first component (1). The process comprises application of an adhesive string (8) along the surface of the second component (2), which is to lie in contact with the first component (1). The adhesive string (8) is applied a short distance from the edge flange (5), and the amount of adhesive in the adhesive string (8) is adjusted so that the adhesive, when the components (1,2) are pressed together, is forced past the edge of the first component (1) and covers the same. Furthermore, a second adhesive string (10) is applied along the surface of the first component (1), against which the edge flange (5) is bent down.

Abstract: A method of securing a two piece plastic nozzle and overlying screw cap closure assembly to a plastic pail cover wherein the nozzle has a cylindrical body portion which is inserted into a cover opening to form a friction fit therewith. The overlying screw cap is then rigidly supported as a sonic welding horn is brought into axial engagement with the protruding nozzle body portion. Energization of the sonic welding horn causes the nozzle body portion to soften and deform radially outwardly into a circumferentially enlarged rivet connection. Continued axial displacement of the sonic welding horn creates a plastic bond about the periphery of the rivet connection so as to close off any leakage path therearound. At the same time any radial dispersion of plastic material resulting from the bonding process is locally contained about the rivet connection periphery.

Abstract: A method and apparatus for securing an enlarged sheet-like fabric to a side face of a panel which is provided with edge frame elements having retaining channels extending therealong. Each retaining channel has a film or bead of a solid adhesive therein. An edge portion of the fabric is positioned to extend over the mouth of the groove, and is then folded over an inserting member which inserts the fabric edge portion into the groove.
