An apparatus for manufacturing rectangular frames of plastic material includes an apparatus frame and welding heads. A material clamp cooperates with an associated frame member to hold the associated frame member in a desired location during a frame assembly operation. A heat plate is movably attached to each welding head. The heat plate can be selectively positioned to an operating position. The material clamp positions the associated frame member in close proximity to the heat plate to heat a set of ends of the associated frame member utilizing only radiation and convection of heat developed by the heat plate. The plurality of welding heads exert pressure on adjoining associated frame members after the heat plate is removed from the operating position in order to weld the adjoining associated frame members together to form a rectangular frame.

A resin frame includes frame members combined into a frame shape that includes a corner portion, and a joint portion joining a pair of the frame members which are adjacent to each other at the corner portion. The joint portion includes an entire-surface welded portion, in which end surfaces of the pair of the frame members are welded to each other over an entire surface in a thickness direction of a plate portion of the frame members, and a partial welded portion, in which the end surfaces of the pair of the frame members are welded to each other on one side of the entire surface in the thickness direction while another side of the entire surface in the thickness direction is not welded. The entire-surface welded portion and the partial welded portion are present at different portions on an outer periphery of the joint portion.

A gasket welding apparatus (10) comprising: a pair of opposed clamping members (16A, 16B) for supporting corresponding first and second lengths of gasket material. The clamping members (16A, 16B) being moveable towards and away from one another by an actuator (58). The gasket welding apparatus (10) comprises a heating element (30), the heating element (30) is moveable between a first position in which it is removed from the clamping members and a second position in which it is disposed between the clamping members.

A manufacturing method of a resin frame includes preparing a plurality of frame members, installing a pair of the frame members in the corner portion in a pair of molds, melting end surfaces of the pair of the frame members as welding margins, and welding the welding margins. The molds respectively includes a reference surface holding the frame members and a blade portion protruding to an inner side with respect to the reference surface. In the welding, in the corner portion, the pair of the frame members are pressed by the blade portions, so that the welding margin protrudes from between the blade portions, the outer peripheral surfaces of the pair of the frame members are bent inward, and the corner portion is made concave with respect to the portions adjacent to the corner portion.

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.

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 movedtogether 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).
