Apparatus for distributing lining material in cap shells where the apparatus has a lining material extrusion means including an extrusion passage positioned above a path of cap shells moving through the apparatus and a rotatable knife positioned above the exit end of the extrusion passage for cutting lining material as it is extruded from the passage. A drive means is provided for rotating the knife and is connected to the knife by means of a transmission means. The transmission means includes at least two sets of non-circular gear pairs with the relative angle between the sets being adjustable whereby the rotational speed of the knife may be varied.

Breast cups having various types of cuts or configurations are initially molded from basically flat sheets of flexible fabric on a bust cup mold having a prescribed configuration. The resulting, three-dimensional molded fabric cup then is cut by a die having a plurality of cutting surfaces, at least a portion of the outermost cutting surfaces serving as guides for alignment with the outer perimeter of the molded cup and a portion of the cutting surfaces cutting the molded breast cup to the desired shape resulting in a breast cup having a size and configuration differing from that of a bust cup initially molded.

An apparatus for molding and stretching at high speed an attachment device integrally composed of a synthetic resin and comprising a head, a cross-bar and a filament integrally connecting the head and the cross-bar to each other is disclosed. The apparatus is comprised of a fixed frame, two movable frame portions, four mold members, two cam rod members, and a cam shaft. The two movable frame members are movably connected to the fixed frame. The four mold members are positioned on the two movable frame members, the mold members being movable relative to one another. The two cam rod members are secured to the fixed frame, and the cam shaft member is mounted on one of the mold members. When the movable frame members are moved relative to the fixed frame, they cause the cam shaft to move along one of the cam rod members, thus causing two of the mold members to be pulled away from the remaining two mold members, thereby stretching the filament connecting portion of the attachment device. As the cam shaft is moved along the other cam rod, the two mold members are moved back towards the other two mold members, thus forceably relaxing the filament.

A tape spool for supporting an endless magnetic tape in a magnetic tape cartridge is cold formed from a single piece of flat plastic stock with upstruck hub segments of a predetermined configuration. The spool also is formed with a central bent configuration including a cylindrical portion for journaling the spool for rotation on a spindle in the cartridge. The preferred hub segments are upstruck from an annular platform which supports a coil of magnetic tape and leave openings in the platform. Each of the hub segments is bent to have an arcuate curvature and collectively define a cylindrical guiding surface for the tape having an upper diameter larger than a collective diameter defined by the lower portions of the hub segments joined to the platform at bent hinge areas.
摘要:
A candle mould having a barrel open at each end and a base having a threaded engagement with one end of the barrel forming a receptacle into which wax can be poured, the base having a central opening through which a wick can be threaded and a plug for sealing the opening. The barrel has diametrically opposed notches formed at its upper end serving as seats for holding a wick holder The wick holder has a central passage through which the wick can be threaded and maintained in position extending axially of the barrel while wax is poured therein.

EXTRUDING A PLASTIC ABRASIVE MIX THROUGH A MULTI-HOLE DIE ADAPTED TO COMBINE EMERGING STRANDS OF THE MIX INTO A SINGLE STRAND WHEREBY THE STRANDS MOVE AT THE SAME LINEAR RATE. THE SINGLE STRAND IS CUT INTO LARGE PELLETS OF UNIFORM LENGTH, AFTER WHICH THEY ARE DIVIDED INTO SMALLER PELLETS CORRESPONDING TO THE ORIGINAL NUMBER, SIZE, AND SHAPE OF EACH OF THE COMBINED STRANDS AND CURED.

A LAMINATED SHEET SUITABLE FOR "ANTIQUING" IS PREPARED COMPRISING A METALLIC FOIL LAYER WITH A TRANSPARENT PLASTIC FILM ADHERING TO ONE SIDE THEREOF. THE PLASTIC FILM CARRIES ON ITS EXPOSED SURFACE AN OPAQUE COATING COMPRISING A PIGMENT DISPERSED IN A BINDER WHICH ADHERES TO THE PLASTIC FILM. THE PHYSICAL STRENGTH OF THE OPAQUE COATING IS SUBSTANTIALLY LESS THAN THAT OF THE PLASTIC FILM, SO THAT PORTIONS OF THE COATING CAN BE REMOVED BY BUFFING ACTION WITHOUT REMOVING THE PLASTIC FILM FROM THE FOIL AND WITHOUT DAMAGING THE FOIL UNDERNEATH. TYPICALLY, THE FOIL IS ALUMINUM, AND AT LEAST THE OUTER PORTION OF THE PLASTIC FILM IS A BIAXIALLY-ORIENTED POLYESTER RESIN. THE LAMINATED SHEET OF THIS INVENTION CAN BE AFFIXED TO AN IRREGULAR SURFACE OF SUBSTRATE AND PRESSED SO AS TO CONFORM TO THE IRREGULARITIES, OR IT CAN BE APPLIED TO A FLAT SUBSTRATE AND EMBOSSED TO FORM AN IRREGULAR SURFACE. THE SHEET OF THIS INVENTION CAN BE USED TO IMPART A METALLIC SHEEN TO SELECTED PORTIONS OF A SUBSTRATE AFTER BUFFING, AND ALSO TO IMPART AN "ANTIQUED" APPEARANCE RESULTING FROM THE FACT THAT THE OPAQUE COATING CAN BE REMOVED BY BUFFING FROM THE HIGH SPOTS OF THE IRREGULAR SURFACE WITHOUT REMOVING THE COATING FROM THE RECESSES AND CORNERS.
