Abstract: Welding equipment for welding plastic workpieces includes two opposite clamping units that can be moved with relation to each other and that are used for fixing and assembling the plastic workpieces to be welded together, plus a heating unit for the plastification of the plastic workpieces at the connection point, whereby a drive unit is provided to generate a drive force that can be transmitted over a dynamic effect segment to the clamping unit and, via the latter, further on to the plastic workpieces. To attain perfect welding results with a greater degree of reliability, the dynamic effect segment has at least one force measurement instrument (38) to record the drive force prevailing there, said unit being connected via a regulating unit with the drive unit (31), whereby the regulating unit controls the drive force generation in the direction of drive (31) by way of adaptation to the predetermined values.

Abstract: A method for extruding synthetic welding material using a welding device for synthetic welding material for the purpose of producing welding seams is characterized by the following features:a) A plastic wire is drawn by a feed device into the welding device (11, 12, 38) for synthetic welding material;b) The plastic wire is fed by the feed device (11, 12, 38) with a specific advancement into a cutting device (26, 36) of the welding device for synthetic welding material;c) In the cutting device (26, 36), pieces are cut consecutively from the plastic wire while forming essentially even cutting surfaces;d) The advancement of the plastic wire and the cutting frequency of the cutting device (26, 36) are in such a ratio to each other that the cut-off length of the pieces is in the same magnitude as the mean diameter of the plastic wire;e) The pieces are then heated until they are plastified;f) The plastified synthetic material is ejected as synthetic welding material from the welding device for synthetic welding mat

Abstract: A machine for bending reinforced thermoplastic workpieces includes a machine frame. First and second spaced rest plates are mounted to the frame, with the plates having a first planer orientation, which define a rest plane, for supporting a workpiece and a second angularly disposed orientation for bending the workpiece. A compression rest is disposed between the plates. A heated bending beam is in alignment with and spaced from the compression rest. A drive system is operably associated with the frame for causing relative movement between the beam and the plates and the rest, so that a workpiece supported by the plates and the rest in the first orientation may engage the beam. The plates are operably interconnected for therefore defining a common pivot axis. A system is provided for causing at least one of the plates to be pivoted about the pivot axis.

Abstract: Welding equipment for plastic plates and the like includes a support. First and second longitudinally extending spaced parallel clamping tables are movably mounted to the support so that the tables may be moved towards and away from each other. First and second clamping beams are provided. Each beam overlies one of the tables and is movable therewith and each beam has a first and portion pivotally associated with one of the tables. A lock system extends from each of the beams and cooperates with another lock system associated with the support. The lock systems permit the beams to be independently pivoted relative to the support. A heated blade is movably positionable between the tables.
