Component having an integral bond and a joining method

A welding method for producing an integral bond of fiber-reinforced plastics parts includes a welding head penetrating one of the plastics parts. The method includes reinforcing at least a first plastics part by a plurality of directional fibers. The re-inforcing fibers reorient themselves within the connection region without severing or breaking.

Apparatus and method for making side seams on absorbent articles

The present disclosure relates to methods and apparatuses configured to bond elastic laminates together between a rotating drum and anvil. The drum includes a fluid nozzle and a press member. As such, a first elastic laminate and a second elastics laminate may be advanced in a machine direction onto the rotating drum. A fluid is heated to a temperature sufficient to partially melt substrate layers of the first and second elastic laminates. As the drum rotates, the press member shifts radially outward from the drum wherein a length, L, of the pattern surface extends in the cross direction across a plurality of elastic strands of first and/or second elastic laminates. And the partially melted portion of the substrate layers of the first and second elastic laminates and the plurality of elastic strands are then bonded together by being compressed between the pattern surface and the anvil roll.

10166720 · 2019-01-01 · ·

A manufacturing method for a multilayer wiring board includes: forming a groove on a surface of a first thermoplastic resin board; forming a modified layer made of resin having a melting point lower than a melting point of resin constituting the first thermoplastic resin board, by applying light to a region of the surface of the first thermoplastic resin board other than a region around the groove; filling the groove of the first thermoplastic resin board with conductive material having fluidity; and bonding a second thermoplastic resin board to the surface of the first thermoplastic resin board, on which the modified layer is formed, by thermocompression bonding.

Electrofusion Fitting Methods
20180363822 · 2018-12-20 ·

The invention provides improvements to electrofusion fitting methods that allow for continuity and repeatability of welds between an electrofusion fitting and a pipe lining (or stand-alone pipe). An electrofusion fitting for joining sections of lined pipe has heating elements configured to create at least one weld between the electrofusion fitting and a pipe lining, however prior to the weld step taking place the electrofusion fitting is heated and expands accordingly to ensure contact with the pipe lining. Preheating the electrofusion fitting also provides a predetermined starting temperature for the fitting and the lining which results in improved fusion cycle reliability. Furthermore, the need for clamps or support frames to support the electrofusion fitting in situ is removed, with corresponding reductions in cycle times, complexity, and hence cost.
