An apparatus and method for joining pipes includes a plate for melting mating surfaces of the pipes to be joined. Additionally, the apparatus utilizes a vacuum in order to push the first and second pipes together in lieu of hand or mechanical pressure which may be inconsistent. Additionally, the vacuum allows the pipes to be joined to settle on each other in order to create a pressure about a periphery of the end of the pipe being joined to the other pipe. The consistent pressure creates a very strong joint between the first and second pipes.

A system for assembling a container and closure comprising an expanding collet which has a plurality of pivoting collet segments, each configured to simultaneously pivot radially outward about a pivot point and comprising. The collet comprises a lip that is engageable with the rim of the open end of the container and an angled tip positioned radially inward from the lip and shaped to press a countersink portion of the closure against an interior wall of the container as the collet segments pivot radially outward. As the container and the chuck are brought together, the rim engages with the lips of the collet segments and causes the angled tips of the collet segments to pivot outward toward the interior wall of the container, thereby pushing the countersink portion of the closure against the interior wall of the container.

A spin fastening system includes a first member and an adhesive layer applied to the first member. A second member is positioned in contact with the adhesive layer. At least a portion of the adhesive layer is cured after the second member is positioned in contact with the adhesive layer to render at least the portion of the adhesive layer substantially rigid. At least one spin fastener is inserted successively through each of the second member, the cured portion of the adhesive layer, and the first member.

A reinforcement and/or lining method is provided, wherein a thermoplastic reinforcement and/or lining element is subject to mechanical energy impact and mechanical pressure by a tool so that reinforcement and/or lining material of the reinforcement and/or lining element is liquefied and pressed into porous material to reinforce the porous material. In at least one axial depth, the reinforcement and/or lining element is segmented as a function of the circumferential angle so that at this axial depth the circumferential wall of the initial opening in first regions is in contact with the reinforcement and/or lining element and in second regions is not in contact with the reinforcement and/or lining element.

A laser welding apparatus is provides that includes: a support member including a heat generation portion which has a size that is limited to correspond to a size of a welding area of a plurality of plastic components and is made from a material that absorbs a laser beam and generates heat, and which generates heat of a temperature that is equal to or greater than a melting temperature of the plastic components; a laser beam irradiation unit for converging a laser beam to be transmitted through the plurality of plastic components, and irradiating the laser beam toward the heat generation portion through the plurality of plastic components; and a welding controller for causing a laser beam to be irradiated at the heat generation portion using the laser beam irradiation unit to thereby cause the heat generation portion to generate heat, and welding abutting faces of a welding area of the plurality of plastic components with heat that is generated.

A device for welding the bottom flange of a stiffener on the side of a skin. The stiffener and the skin are made of a composite comprising a thermoplastic polymer matrix. The device comprises a punch, an anvil and a press to make a clamping between the punch and the anvil. The punch comprises a part forming a pressure table with a cross-section width less than or equal to the width of the stiffener bottom flange and a heating element with width less than the width of the pressure table. The anvil comprises a cooling component and has a cross-section width smaller than the width of the skin. A method for implementing the device.

A machine and method for making bags is described and includes a web traveling from an input section to a rotary drum, to an output section. The rotary drum includes at least one seal bar, having a single sealing zone, and a weakening zone disposed within the single sealing zone. The single sealing zone may be a heated perforator, includes a heating wire. The heating wire may be an NiCr wire stitched into the heater, and be disposed on a cap or on the seal bar. The weakening zone may create a line of weakness that is uniform or varies in intensity. The sealing zone may include temperature zones, cartridge heaters, cooling air, or heated air, or a source of ultrasonic, microwave or radiative energy.

In a process for welding plastic parts together, an IR shield redirects IR radiation emitted from a heater of a heating tool so that IR radiation which would otherwise be directly incident on certain portions of a plastic part and/or on other parts of the heating tool is avoided.
