Abstract: A machine for applying an adhesive pad to the ends of semiconductor device packages includes a punch assembly, a tape feed assembly, and a package feed assembly. The tape is incrementally fed to the punch assembly where semiconductor packages are individually brought into alignment. The punch assembly first shears an adhesive pad from the tape and thereafter applies the pad to the package. The punch member of the punch assembly includes a resilient tip which assures that the tape is securely attached to the package and helps prevent damage to the package. Semiconductor device packages having such taped ends are less likely to be damaged in subsequent processing and handling.

Abstract: Apparatus for applying tape to a forwardly traveling carton includes a first projecting tape applicator which lies in the path of carton travel. As the carton strikes the first applicator, tape is applied to the carton front panel, the traveling carton depressing the applicator to allow it to apply and wipe tape around the corner formed by the front panel and onto a horizontal panel. A push finger carried on the tape applicator engages for a time with a tape cutter. On engagement of the push finger with a cam near completion of unit depression travel, the finger disengages the cutter and releases it to sever a tape length from the tape supply. A roller in the depressed applicator unit wipes the severed tape length along the horizontal panel for the length that the tape extends along the panel. A second tape applicator unit which moves from projecting to depressed position in tandem with the first unit is located downstream of the first applicator.

Abstract: From a casing destined for the fixing to a sealing machine project, at rest, an inlet roller and an outlet roller, which the same carton to be sealed forces to return into the outline of the casing during their advancement from one to another end of the casing. To the inlet roller is supplied an adhesive tape, which the same carton picks up and causes to adhere to the front wall, the adjacent horizontal wall and the rear wall by means of said inlet and outlet rollers. A cutting blade is arranged between said inlet and outlet rollers and is provided with suitable actuating means, which cause it to carry out a rapid run of cutting of the adhesive tape after the rear wall of the carton has overcome the blade a prefixed length.

Abstract: Information storage mediums such as video discs and digital audio discs are fabricated by extruding a mass of electrically conductive synthetic resin into a block assembly composed of a pair of separable blocks in which the mass is molded into a cake that is then carried by one of the blocks as separated into a press in which the cake is pressed into an information storage medium or disc blank. The blank is transferred into a trimmer for trimming an overflow off the disc blank as an annular scrap, which is in turn chopped by a chopper into pieces for reuse. A disc from which the scrap has been removed is fed to a hot stamping machine in which an identification foil piece is attached with heat to the disc. The disc with the foil piece stamped thereon is punched to form a central hole by a punching machine.

The apparatus also includes steering means for automatically shifting a belt of the conveyor to maintain it in proper alignment and a scrap removal station for removing the web after the cutting and sealing operation.

Abstract: A method and apparatus for forming multilayer ceramic substrates from large area ceramic green sheets, each having an array of layer sites thereon, by serially aligning each individual layer site with respect to a die cavity and punching the aligned layer site into the die cavity to thereby stack the requisite number of aligned layer sites. Individual layer site alignment ensures that each layer site is aligned with respect to the die cavity so that the dimensional tolerances between layer sites on the large area green sheet are eliminated. Thus, as large a green sheet as is cost effective may be employed, notwithstanding the fact that dimensional distortions on the large area green sheet would preclude alignment of corresponding layer site vias on superimposed large area green sheets.
