An automated process is provided that includes loading a blank on a carrier and moving one of the carrier or the blank to more than one of a number of stations. The carrier has at least a portion with a desired shape that provides the blank with a stretched condition. Each station performs an operation on the blank while the blank is mounted on the carrier.

A method is devised for continuous fabrication of thin membrane gloved enclosures in which a folded membrane ribbon is closed along the opposed longitudinal edges by a reversible closure comprising an interlocking set of beads. The ribbon is then repetitively stamped by a heated filament in the shape of a joined string of gloved enclosure and the interlocked beads are then separated, folded over to overlie the gaps formed and a second severing operation then parts the individual enclosures. In this manner a cuff is formed that can then be extended on top of an article grasped.

A heat-conducting adhesive compound is provided with a sintered layer (3) that consists of heat-conducting power, is arranged between two workpieces and contacts each workpiece in a two-dimensional manner. The compound is also provided with an adhesive (4′) which fills openings (33) on the surface (31) of the layer and adheres to the two workpieces. In a preferred embodiment, the sintered layer consists of silver powder. The sintered layer is produced between the workpieces and the layer is subsequently filled with a liquid adhesive (4) which is then hardened.

A multi-layer elastic flat-shaped article having a predefined shape, consisting of at least two outer layers made of a porous fibrous or filamentous batting, and at least one inner layer, disposed between and adherent to a pair of said at least two outer layers. The inner layer is applied as at least one adhesive skein forming a latticework configuration. The adhesive skein is formed of a thermoplast having elastic properties at room temperature, and being adapted to recover its latticework configuration after tensile loading. The resulting article flat shaped article may be elastically stretched, and return to its original configuration. A preferred method for depositing the thermoplast is a printing process, for example intaglio printing, flexoprinting or screen printing. Nozzles may also be used to extrude hot thermoplast in a pattern defined by a relative movement of the outer layer or layers and the nozzle. The pattern may be continuous or interrupted.

A method for rotatably balancing a driveshaft includes the initial step of using a conventional balancing apparatus is used to determined the size and location of the balance weights needed to properly balance the driveshaft. Next, an adhesive material is applied to either or both of the driveshaft and the balance weight. The balance weight is preferably formed having an inner surface that is curved to conform with the curvature of the outer surface of the driveshaft. The preferred balance weight is further formed having a relatively thin outer peripheral rim portion having a plurality of radially outwardly extending teeth formed thereon. The overall size of the balance weight may be varied to provide differing amounts of weight for facilitating the balancing process. A sufficient quantity of adhesive material is provided between the driveshaft and the balance weight such that when the balance weight is pressed against the driveshaft, at least a portion of the adhesive material is extruded outwardly into contact with at least a portion of the outer peripheral surface of the balance weight. The extruded portion of the adhesive material is then exposed to an accelerated curing process, such as ultraviolet radiation, heat, and the like, so as to cure at least that portion of the adhesive material to temporarily secure the balance weight to the driveshaft, thereby allowing the driveshaft to be immediately re-tested on the balancing apparatus to confirm that proper rotational balance has been achieved. The uncured first portion of the adhesive material located between the driveshaft and the balance weight 40 will later cure without the use of any accelerated curing process to permanently secure the balance weight to the driveshaft.

A tape dispenser with a hidden blade includes a body, a press plate provided at a front side of the body and possible to be pressed to move rearward elastically to push down a blade fixed on a blade base to force the blade to protrude out of the body a little for cutting a tape. After the tape is cut and the press plate is released manually, the blade with the blade base together is raised up to the original position elastically and automatically, kept safe to use and prevented from damage by accidental collision by something.

By utilizing specially processed waste carpeting as a filler in the production of carpet backcoating, roofing materials, or other similar products, the amount of waste carpeting that is landfilled or otherwise disposed of is significantly reduced as is the need for mining the mineral fillers. Waste carpeting (post-consumer and/or waste from new carpet manufacture) containing calcium carbonate and a thermoplastic resin is collected and size-reduced to a size corresponding to the size of calcium carbonate typically used as a filler. The size-reduced waste carpeting is added as filler to at least one other material, such as polymers in standard latex, EVA, or PVC carpet backcoatings, to provide a composite used in the manufacture of a useful product (like carpet backcoating), and then the composite material is used to make the useful product (such as carpet backcoating, which is used as a primary or secondary backcoating in the manufacture of new carpeting). The waste carpeting may provide between 0-100% of the filler of carpet backcoating, with any remainder made up by conventional fillers, such as calcium carbonate.
