A pile article is provided having a band of textile material, and a plurality of fiber loops defining a pile having sides from ends extending longitudinally along the band. The band is ultrasonically welded to the ends and a portion of the sides of the pile, and is sufficiently wide to support the sides of the pile substantially upright. An interior textile strip may optionally extend longitudinally within the pile at the ends of the pile and within a portion of the pile sides.

A shaped product, which travels from a shaping die, is passed through a delimiting space between a pressing roller provided in a floating frame of a pressing member and a windowpane introduced in under the pressing roller to be forcibly fitted to the windowpane. Thus, the shaped product is uniformly unified to a peripheral portion of the windowpane by preventing variations in a adhesion force from occurring.

摘要:
An apparatus and method for joining together two or more fabric components without thread, the components including at least one ultrasonically bondable component. The apparatus comprises an ultrasonic horn operable to emit ultrasonic energy through a fabric-engaging end face thereof, and a rotatable anvil support having an outer peripheral surface on which one or a plurality of anvil supports are formed. The anvil support and the horn are arranged so as to define a nip between the respective fabric-engaging surfaces thereof for receiving the components to be joined. The anvil support rotates about an axis thereof as the components pass through the nip such that the outer peripheral surface of the anvil support defining the anvil structures is stationary relative to the components passing through the nip. The horn emits ultrasonic energy and the anvil structures focus the ultrasonic energy on one or more regions of the at least one ultrasonically bondable component contacted by the anvil structure(s) so as to locally heat and bond the one or more regions.

Apparatus for manufacturing, on an automatic continuous basis, successive album pages of predetermined length and width each of which consists of a base sheet having a reinforcing tape bound thereto in overlapping relation with each edge thereof comprises a series of five stations: a tape preparing station, a sheet loading station, a glue station, a page assembly station and a cut-off station. In operation, one of two tapes has staple-like hinges applied thereto, both tapes are coated on one surface with glue, and both tapes advance to the assembling station to which successive sheets are fed lengthwise from the sheet loading station. In passing through the page assembling station, the tapes are folded and pressed into overlapping adhered relation with the side edges of the sheet to form a web consisting of a series of pages held together by intermediate pieces of the two tapes. The tapes, the successive sheets and the resulting web are drawn through the apparatus by a reciprocating carriage. During forward feeding movement of the carriage, the web is clamped to the carriage, and during each return stroke of the carriage, the tape is clamped to the cut-off station while the pieces of tape connecting the leading page to the remainder of the web are cut out to leave that page free for further disposal. The apparatus is adjustable to accommodate sheets of different lengths and widths.

A tape delivery system useful for applying a plastic tape to a sheet of scrim reinforced tube stock is disclosed. Tape forming techniques are employed to shape a length of plastic tape and to apply that tape to a bottom margin region of the tube stock material to form a scrim reinforced open-mouth container bag.

IN ONE EMBODIMENT OF THE INVENTION, MULTIPLE GLAZED UNITS ARE FABRICATED BY HEATING A THERMOPLASTIC, SPACER DEHYDRATOR ELEMENT. THE ELEMENT IS HEATED TO A TEMPERATURE SUFFICIENT TO MAKE THE ELEMENT PLASTIC AND RENDER THE ELEMENT SURFACES VISCID. A PAIR OF GLASS SHEETS ARE POSITIONED ABOUT THE HEATED ELEMENT AND URGED TOWARD EACH OTHER AGAINST THE ELEMENT TO FORM A HERMETIC SEAL. IN ANOTHER EMBODIMET, A COMPOSTE STRIP COMPOSED OF A STRIP OF PRECURED, MASTIC SEALANT MATERIAL HAVING A BENDABLE CARRIER TAPE ADHERED TO ONE SURFACE AND A THERMOPLASTIC, SPACER-DEHYDRATOR ELEMENT ADHERED TO THE OPPOSITE SURFACE IS HEATED. THE COMPOSITE STRIP IS HEATED TO A TEMPERATURE SUFFICIENT TO MAKE THE ELEMENT PLASTIC A SEGMENT OF THE COMPOSITE STRIP IS APPLIED TO A PARI OF GLASS SHEETS HELD IN SPACED RELATIONSHIP TO EACH OTHER THE SEGMENT IS APPLIED IN SUCH A MANNER THAT THE ELEMENT IS INSERTED BETWEEN OPPOSED, MARGINAL EDGES OF THE GLASS SHEETS WITH THE SEALANT MATERIAL FACING THE PERIPHERAL EDGES OF THE GLASS SHEETS. THEREAFTER, THE CARRIER TAPE IS PRESSED SO AS TO FLOW PORTIONS OF THE SEALANT MATERIAL INTO HEREMETICALLY SEALING CONTACT WITH THE EDGES OF THE GLASS SHEETS TO PRODUCE A FINISHED UNIT. IN STILL ANOTHER EMBODIMENT, THE COMPOSITE STRIP, INSTEAD OF INCLUDING A PRECURED, MASTIC SEALANT MATERIAL, INCLUDES A CURABLE MASTIC SEALANT MATERIAL. THE COMPOSITE STRIP IS HEATED TO A TEMPERATURE SUFFICIENT TO MAKE THE ELEMENT PLASTIC. BEFORE THE SEALANT MATERIAL CURES, THE COMPOSITE STRIP IS APPLIED AS BEFORE TO THE PAIR OF GLASS SHEETS. THEREAFTER, THE PRESSING STEP IS PERFORMED TO PRODUCE A FINISHED UNIT.
