A welder for constructing and welding plastic fenestration structures, including parts storage bins structured to store and support parts to be assembled to create the plastic fenestration structures; wheels that receive the parts from the parts storage bins; aligners that position the parts relative to one another; heating plates that apply heat to ends of the parts thereby rendering at least a portion of the ends of the parts molten; parts shifters operably shiftable between a first position adjacent the wheels and a second position remotely located from the wheels that shift the parts to a fusing position in which adjacent parts are abutted together at a fusing station to produce the plastic fenestration structure; and at least one cooling station at which the plastic fenestration structure is held.

A window frame assembly for installation within a garage door having front and rear exposed surfaces and one or more window openings. The assembly includes front and rear window frame members which are installed within the door openings in the garage door. The front and rear members are brought toward each other to sandwich the borders of each of the window openings while also capturing an associated transparent pane. A series of fastening members are used to hold the front and rear frame members securely against each other. The front and rear window frame members are made of synthetic polymeric starting stock starting materials which, together with the transparent panes, are able to withstand hurricane force winds and associated blowing debris.

The process for the manufacture of windows/doors (1), characterized by the fact that it comprises the following steps: providing at least one inner panel (2) for windows/doors; providing a plurality of plastic profiled elements (3) for windows/doors, each of the profiled elements (3) comprising at least two areas to seal (5), coupleable to the areas to seal (5) of the other profiled elements (3), and at least one longitudinal slot (6), in which a respective perimeter side (4) of the inner panel (2) is insertable; performing a step of mechanical machining by chip removal on at least one of the areas to seal (5); heating the areas to seal (5); coupling the heated areas to seal (5) to one another by pressing the profiled elements (3) one against the other to maintain the areas to seal (5) in mutual contact and define the frame for windows/doors, the coupling taking place with the inner panel (2) inserted in the longitudinal slots (6) to define a window/door (1) which is composed by the frame and by the inner panel (2) contained in the frame.

A tunnel segment gasket and a method for making and using a tunnel segment gasket (1, 1) comprising a shaped profile (3, 3) having at least two anchoring legs (5, 5) for casting in to a tunnel segment (6, 6); a plurality of longitudinally extending bores (7, 7); a shot film joint (43) and a strengthening element (11, 4) at the base (9) of the gasket (1, 1).

A component part for a motor vehicle having a hollow profile portion of a fiber-reinforced plastic and a load introduction element of a metal material. The hollow profile portion and the load introduction element are connected in a common connection portion via a nondetachable, glued plug-in connection in which an end portion of the load introduction element and an end portion of the hollow profile portion engage in one another by positive engagement. The end portion of the load introduction element has a spline with teeth extending in longitudinal direction of the common connection portion so that the stiffness of the end portion of the load introduction element reduced in longitudinal direction of the common connection portion.

A method for welding two hollow profiled rods made of plastic to form a window frame. The profiled rods to be joined together are heated to a predetermined temperature by inserting a welding plate between their connecting surfaces and pressing the same against the welding plate, forming outer and inner beads, and the profiled rods are pressed together under pressure after removing the welding plate, with a simultaneous increase in the size of the weld bead. For all cross sections of the profiled rods and the plastics used for manufacturing the window frames, to obtain a type of shadow groove on the top side and/or front side and on the bottom side and/or rear side of the finished window frame in the area of or near the connecting sites of the finished window frame, only the outer beads formed on the visible surface of the subsequent window frame in the area of or near the connecting sites of the two profiled rods are pressed slightly inward after removing the welding plate forming an oblique edge, and then are removed together with the inner beads, and then the connecting surfaces of the two profiled rods are joined together.

The invention relates to a finishing device for removing the weld bead generated during welding of a window or door frame or frame section at the mitered surfaces, wherein the finishing device comprises a support surface for the frame or frame section and a processing arm for supporting a tool holder, and the processing arm consists of a plurality of arm elements that move in hinged fashion relative to one another but can also be fixed in place, wherein the tool holder comprises at least two cutting tools driven by a rotational drive, said tools rotating about a tool axis and at least one tool laterally next to the blade of the tool, contact sides.

The machine (1) for sealing plastic profiled elements comprises: a base frame (6); a pair of retention members (7, 8), adapted to retain respective plastic profiled elements (P) having respective areas to seal (Z) with a first main edge (2a), a second main edge (3a), a first lateral edge (4a) and a second lateral edge (5a); a heat-sealing element with heated plate (11); sliding means (9, 10) of the retention members (7, 8); removing means (13, 14) adapted to remove material from the areas to seal (Z) at least at the first lateral edges (4a); lateral containment means (23, 24), which are adapted to abut on the areas to seal (Z) at the first lateral edges (4a) for the containment of a lateral sealing bead (S) and which comprise at least a V-shaped element (23) having two sides (25) arranged in a V pattern which are adapted to abut on at least a portion of respective first lateral faces (4) of the profiled elements (P).
