Abstract: An improved reel for dispensing threaded-pipe sealing tape is disclosed, wherein a tape retarding element is provided and mounted for circular movement about the periphery of the reel. The tape retarding element is mounted between the side flanges of the reel so that an applied force must be tangentially directed thereto to overcome the friction between the tape retarding element and the side flange portions between which the tape retarding element is mounted. The tape retarding element allows for the paying out of the tape for its wrapping about the threaded end of a pipe, but prevents the accidental unwinding of the tape upon the dropping of the reel from a user's hand.

Abstract: The invention relates to a method of wrapping a spool with metal ribbon, as well as to the spool and to the ribbon designed to carry out the method. The method is particularly characterized by the fact that, while the ribbon (12) is still being profiled only transversely, it is first kept tangent to the band (7) of flanges (4), then, as it is being deformed elastically, it is wound progressively and, as winding proceeds, the edges are fixed on said binding (7) of the flanges (4) by applying stresses on the median portion in such a way as to cause it to bulge outwardly.

Abstract: A method and a package are described for the takeup, shipment, storage and individual dispensing of a plurality of rolls of flat elongated material, for example, conveyor belting. The package includes a plurality of side-by-side rolls of flat elongated material, each roll being wound on its own shell. Between each pair of shells there is provided a pair of divider plates. The divider plates are joined at their radially outermost ends to an upper frame member. The upper frame member is joined to a pair of side members which are joined to the outer ends of the assembled shells and to a central member which extends axially through the assembled shells. At least two U-shaped tie members are provided which extend axially across the rolls and are joined at their radially inner ends to the outer ends of the assembled shells. Methods assembling and dissembling the package are also described.

Abstract: An improved envelope seal for a tire assembly (10) is provided to protect the bonding surfaces of a tire casing (12) and tread material (14) from exposure to steam and other elements within a pressure chamber (126) during curing. A two piece road curing rim (26) is provided with rim members (36, 38) which extend adjacent the sidewalls (56) of the tire (16). Annular seals (37, 39) are secured about the peripheral edges of the rim members (36, 38) and define first annular sealing faces (86, 88) and second annular sealing faces (90, 92). A flexible envelope (18) covers the bonding surfaces of the tire and extends radially inward adjacent the sidewalls of the tire. The envelope has lips (68, 70) extending laterally outward from the outer surface thereof and having annular sealing faces (94, 96) defined thereon. The envelope (18) is inflated to align the first annular sealing faces (86, 88) and annular sealing faces of the envelope lips (94, 96).

At least two -shaped tie members are provided which extend axially across the rolls and are joined at their radially inner ends to the outer ends of the assembled shells. Methods assembling and dissembling the package are also described.

Abstract: The reel is constructed with a pair of end frames, each of which has an end board provided with elongated apertures in the end board. The apertures permit viewing of the contents of the reel when the reel is mounted in a horizontal storage position. The apertures also provide a manual means for grasping of the reel in order to remove the reel from a shipping carton. The hook-containing strips of each end frame terminate short of the corners of the cardboard to mount the reel contents in a slightly suspended condition in a shipping carton.

Abstract: A shipping carton is made with a wrapper which is placed between the end frames of a reel. The wrapper has folded over flaps at the transverse edges which are biased against the end boards of the respective frames and abutted at the ends against the hook strips of the reel. The placement of the wrapper between the end frames and the abutment of the flaps against the hook strips serve to strengthen the carton.The winding machine includes inwardly directed clips on the outer ends of holders on the end frames for holding the hook strips in rigid condition during winding of a pile fabric on the reel.

Abstract: A package for a roll of strip material such as linered or unlinered pressure sensitive adhesive tape. The package includes a protective housing around the roll of strip material, and brake members extending radially of the roll and bearing against circular facing sheets on the side surfaces of the roll to restrict its free rotation and cause a predetermined generally constant tension in the strip material being withdrawn from the roll.

Abstract: A cassette and associated spool for film, sound track and like material, with means for supporting the outer areas of the spool flanges to prevent sagging and warping of the spool flanges. The support means comprises interengaging formations on the cassette and on the spool. The interengaging formations may include projections on one of the cassette and the spool and recesses on the other of the cassette and the spool. Alternatively, the formations may comprise resiliently and radially displaceable areas of the cassette side wall which locate between the spool flanges when the cassette lid is fitted to the cassette base.

Abstract: In a coil of material wound in a series of figure-8 coils with the crossovers progressing around the package but being interrupted at one point to provide a radial opening into the axial opening of the coil, in order to produce a thick-walled coil the material is first wound in a normal way with varying gains in order to produce a set of dense inner layers, while the outer layers are wound without variation in the gain to produce a honeycomb structure. The honeycomb section is of greater width (axially of the package) than the inner layers. A plurality of pins slidably mounted on a strip are pushed into the outside of the package through the openings in the honeycomb, whereafter the outer layers are compressed axially while retaining the pins within the outer layers. The pins permit payoff of the outer layers without danger of their collapsing and thereby forming kinks or twists within the package.

Abstract: A permanent magnet synchronous motor includes a coil protector substantially covering a coil of wire and terminations on a bobbin. The coil protector electrically insulates the coil of wire from external structure of the motor and provides physical protection to the terminations of the coil of wire.

Abstract: A packaging arrangement is shown herein for protecting high voltage, pipe-type, impregnated paper insulated cable during long distance shipping. An annular channel is provided along the inside radial face of a cable reel to receive first and second vapor barrier blankets which may comprise laminated layers of polyolefin, aluminum foil and polyethlene. An adhesive is spread throughout the open portion of the channel. A first steel banding wire annularly secures the first two blankets within the annular channel and a synthetic rubber adhesive is disposed over the two blankets and wire. A third blanket comprising a laminate of polyvinyl chloride and Nylon is then disposed over the composite formed up to this point and a second banding wire is tightly secured about the overall composite. The second wire is so positioned as to bear down in a plane extending generally parallel to the radius of the circle described by the first wire so as to be axially spaced therefrom.
