摘要： A method for connecting plastic profile parts (2) brings into contact at least one profile part (2) and a heating surface (34) of a heating, element (36) so that the profile part (2) begins to melt in its welding area before it is joined together with the other profile part (2). A delimiting element (7) regulates the flow and deformation of the melt material. The delimiting element (7) has at least one contact element (21) and a molded part (22), which are movable both in relation to one another and in relation to the profile part (2). During the melting of the at least one profile part (2), the contact element (21) is moved—together with the molded part (22)—relative to the at least one profile part (2) and relative to the heating element (36) out of, a resting position in the direction of a working position, whereby at least the molded part (22) is kept in contact with the heating surface (34) and the contact element element (21) is, kept in contact with a profile surface (9). When a changeover is made from melting to compressing, the relatively movable contact element (21) is moved together with the molded part (22) in the direction of its working position so that the delimiting element (7) projects beyond a free front edge (4) of the at least one profile part (2) and creates a holding plane (37).

摘要： The invention relates to a device for machining frames welded from profile pieces such as window or door frames made of plastic, said device comprising at least one machining head and machining tools which are mounted thereon and can be delivered to the relevant machining position on the frames. The machining head can be pivoted around an axis and has a positioning shaft which is mounted at an angle with respect to the pivot axis and on which the machining tools are mounted. The positioning shaft extends on both sides of the machining head with machining tools at both end regions of the positioning shaft.

摘要： At least two profiled parts (1) are fixed to profile supports (2) that can be moved relative to each other. The profiled parts (1) are each partially melted at an end joining face (10) with a heating element (5) in a melting step and, after the heating element (5) has been removed, the partially melted joining faces (10) of the profiled parts are pressed against each other in a joining step, until the molten materials brought into contact with each other there cool down and solidify, forming a welded connection. To avoid or reduce occurrence or development of a welding bead, in a separating step that is carried out before the joining step, a mating tool (6, 29) is guided through the melt along the separating edge (9) of the limiting element (3), in order to separate the excess melt (7) that has escaped over the separating edge (9).
