A method of joining overlapping thermoplastic membrane components in which a first thermoplastic membrane component and a second thermoplastic membrane component are positioned in overlapping relationship between a pair of complementary molding surfaces, with at least one of the complementary molding surfaces being defined by an electrically conductive metal susceptor. Heat is generated in the metal susceptor and transferred by thermal conduction from the metal susceptor to overlapping portions of the first and second thermoplastic membrane components to locally melt and coalesce at least a portion of the thermoplastic material of the first thermoplastic membrane component and at least a portion of the thermoplastic material of the second thermoplastic membrane component. The molten thermoplastic material of the first and second thermoplastic membrane components forms a zone of coalesced thermoplastic material that, upon cooling, forms a solid weld joint that fusion welds the first and second thermoplastic membrane components together.

This invention describes a 3-layer insulation material comprising a first fabric layer, a second fabric layer and a third fluted intermediate fabric layer between the first and the second fabric layers, the fluted intermediate fabric layer being attached alternately to the first and the second fabric layer with longitudinal seams forming longitudinal channels for the insulation material having individual insulation material bundle inside each longitudinal channel. Also disclosed are a method and an arrangement for producing the same.

A sonotrode includes multiple layers of a material melted to one another to form a structure. The structure provides a base that has an attachment feature that is configured to operatively secure to an ultrasonic converter. The structure includes a shaft that extends from the base to a terminal end that provides a working surface that is configured to selectively engage a workpiece.

The invention relates to a system for producing a sealed connection of a press connector to a workpiece, in particular to a pipe, preferably to a plastic pipe, with a pressing tool for pressing a press connector and with a pressure tool for driving the pressing tool. The pressure tool is arranged to output a hydraulic pressure at a pressure generation point The pressing tool is arranged to receive a hydraulic pressure at a pressing location and to press a press connector accordingly. The pressure tool and the pressing tool are connected via a hydraulic pressure transmission connection, the pressure generation location and the pressing location being remote from each other. A corresponding method for producing a tight connection of a press connector to a workpiece, in particular to a pipe made of a flexible material, preferably a plastic pipe, as well as a press force translator and a press tool are also described.
