A method and a device (10) for welding at least two profiled sections (1) for window or door frames or leaves uses a heating unit (4) introduced between the profiled sections (2, 3) to be joined. At least two heating elements (5, 6) of the heating unit melt the profiled section ends (2, 3) at the end surfaces to be joined. In order to chamfer, in particular remove, a profiled section edge layer (20) of the profiled section ends (2, 3) along the layer surfaces (12, 13) thereof, at least one tool, in particular at least one cutting blade (7, 8), is arranged on the heating elements (5, 6) and is moved such that the material (9) to be melted is displaced into the profiled section interior (11) or into the interior (12) of the profiled section chambers (13). A compression device compresses the profiled section ends (2, 3).

Embodiments herein include compositions, extruded articles, and methods of making the same. In an embodiment, an extruded article is included. The extruded article can include an extruded segment comprising a first composition. The first composition can include a polymer resin, an impact modifier and fibers. In some embodiments, the extruded segment can have a surface exhibiting an average depression depth of less than 0.0045 inches (0.1143 mm). Other embodiments are also included herein.

The present invention relates to a guide rail, a device and a method for the manufacture thereof.

This rail (1) is remarkable in that it is made from an injected plastic material and in that it comprises at least one portion having the shape of a tubular profile (10) longitudinally split over at least one portion of its length, this rail able to be straight or curved in the shape of an arc of a circle.

Process for the realization of counter-mould elements for the containment of welding bead of plastic profiled elements, in which counter-mould elements (1) have a main body (2) adapted to receive in abutment a pair of profiled elements of plastic material welded together to obtain a frame for windows/doors, each profiled element comprising a welding surface weldable to the welding surface of another profiled element in a welding configuration in which the lateral faces of profiled elements are substantially adjacent to one another and define a locator surface, wherein the process comprises: a phase of acquisition of the profile of a portion of the lateral faces; a phase of definition of the profile of a contact surface (3) of the main body (2) adapted to receive in abutment the locator surface, the profile of the contact surface (3) being substantially complementary to the profile of the locator surface; a phase of three-dimensional molding obtained by means of a three-dimensional molding device (4) to obtain the main body (2) starting from the profile of the contact surface (3) obtained in the phase of definition.

A method for producing composite profiles comprises providing a first profile part extending in a longitudinal direction, made from a first plastics material, with a profile region produced from a second plastics material thermally plasticizable at a first temperature, providing a second profile part extending in a longitudinal direction, made from a material not thermally plasticizable at the first temperature, and with a receiving structure formed along the longitudinal direction of the second profile part, with which the profile region of the first profile part is connectible, bringing the profile region of the first profile part into contact with the receiving structure of the second profile part, plasticizing the second plastics material of the profile region by heating to the first temperature and deforming the plasticized profile region while forming a positive engagement between the profile region and the receiving structure while maintaining the geometry of the receiving structure.
