A device includes at least one bearing shield, at least one sonotrode which is rotatably mounted in the bearing shield, at least one anvil which interacts with the sonotrode to process the packing material, at least one other bearing shield to rotatably mount the anvil, whereupon a coupling mechanism is arranged to mechanically couple both bearing shields. The coupling mechanism is configured so that a relative motion between both bearing shields is made possible.

Two workpieces composed of a resin workpiece and a resin workpiece, or composed of a resin workpiece and a glass substrate are bonded to each other such that troubles, such as an alignment shift and breakage etc. are not generated, while ensuring bonding uniformity. A first workpiece is placed on an inverting stage of an inverting stage unit, a second workpiece is placed on a work stage of a pressurizing stage unit, and UV light is radiated from a light irradiation unit. Then, the inverting stage is inverted 180°, the workpieces are overlapped each other on the work stage, and the workpieces are pressurized and pre-bonded to each other. Then, the workpieces in the pre-bonded state are transferred to a heating stage by a transfer means, the temperature of the workpieces is increased to a predetermined temperature by heating the workpieces, and the temperature is maintained until bonding is completed.

An apparatus for stacking a plurality of pieces of material has an assembly region, one or more platens on a first longitudinal side of the assembly region, and, a plurality of press rams on a second longitudinal side of the assembly region opposite the first longitudinal side. The press rams are movable transversely across the assembly region to immobilize or partially immobilize pieces of material in the assembly region permitting accurate and precise alignment of the pieces relative to each other in the assembly region.

A method and apparatus (84,94) for controlling an assembly for bonding a cover (22) over the undulating surface of a foam cushion (10) controls a tool actuator cylinder (80) to tilt a tool (18) to a loading position to permit placing the cover (22) and an adhesive layer (82) on the tool, tilts the tool to a working position to permit placing the cushion on the tool, controls a plate actuator cylinder (62) to lower and raise a compression plate (58) to force air from an interior of the cushion, controls a ram actuator cylinder (90) to lower a ram (14) to pierce the cushion with a plurality of hollow needles (44) attached to a plenum chamber, controls a heater (38) to heat compressed air and eject the hot air from the needles into the cushion to elevate the temperature of the cushion and melt the adhesive, and lowers and raises the compression plate to force hot air from the interior of the cushion to cure the adhesive and bond the cover to the cushion. Then the ram (14) is raised to extract the needles (44) from the cushion (10) as the compression plate (58) is maintained in place to hold the cushion and the cover (22) against the tool (18).

Disclosed is an integral one piece plastic fastener for securing belt ends together. The fastener has upper and lower plastic plates clasped to a belt end with integral, hollow rivets projecting from the upper plate through openings in the bottom plate and with hollowed ends of the rivets deformed to form rivet heads for maintaining clasping of the plastic plates on the belt end. Also disclosed is a rivet head forming tool which smoothly forms rivet heads by a spinning process in which a rotating tool is forced against the hollow end of the rivet and spun with sufficient velocity and applied with a high force to create a sufficient heat and pressure to cause the end wall of the rivet to curl and turn over radially outwardly to form a rivet head tightly pushing against the lower plate of the fastener.
摘要:
An integral thermoplastic sheet being formed of a plurality of separate sheets welded together in a longitudinal seam along their edges, the seam having been formed by the melting together of the inner surfaces of the separate sheets and being of uniform welded strength in a direction across the seam in a direction transverse to the longitudinal direction of the seam.
摘要:
Apparatus for ultrasonically splicing together end-to-end two lengths of moving picture film or the like with a patch of splicing tape therebetween, comprising an ultrasonic horn, a stage for the lengths of film which is movable toward and away from the horn, tape feeding mechanism for intermittently feeding tape from a roll into position on the surface of said horn, and mechanism for cutting a patch of desired width from the end of said tape. The stage and the horn are provided with vacuum aperture for holding the films and the patch in place. An automatic control system acts to perform the operating steps in the necessary sequence.
