Abstract: Process for manufacturing joint connections on mouldings of reinforced and/or unreinforced thermoplastics by the vibration welding process. In order to obtain high quality factors of the welded connections a contact body is introduced between the joint surfaces of the mouldings and welded to the mouldings under the action of linear or angular oscillations, the contact body being variable within wide limits regarding its geometrical dimensions and its material characteristics.

Abstract: The apparatus for bonding moulded parts by ultrasound, in particular for producing optical storage discs, comprises a sonotrode (1), via which ultrasonic vibrations can be transferred to individual regions of the moulded parts (8, 9), a counterpressure plate (2) and a device (11) for the mutual positioning of the moulded parts. The sonotrode has a clearance (3) with offset vertical bounding faces (4, 5), of which the bounding face (4) largely covers the outer edge of the moulded parts and the bounding face (5) is formed by the device for positioning the moulded parts.

Abstract: Use of flexible semi-finished products, which comprise one or more textile sheet-like structures impregnated with a thermoplastic or laminated, for producing hollow bodies, in particular tubes for the ventilation of passenger compartments. The semi-finished products are in this case made to curve out tubularly and the edges of the semi-finished products are joined to one another such that they overlap or after they have been folded. Preferably coming into consideration as textile sheet-like structures are woven fabrics, mats, nonwoven or laid fabrics which are laminated with aromatic polyethers or polythioethers.
