The invention concerns the field of window seals to be encased in a frame, in general a motor vehicle door frame. The seal is intended to be in contact with part of the perimeter of a window and comprises a guide slot strip consisting of two upward segments and an upper segment, and a sealing strip extending between a low part of one of said upward segments and a high part of the other of said upward segments. The sealing strip is molded in a single piece and comprises an upward curved part, and is attached at least at its upper end to one of the upward segments of the guide slot strip.

Novel window and patio door frame members are formed by an extrusion process that provide these members with at least one channel and with an outer weather resistant surface and an internal imitation wood surface together with integrated sealing strips formed in the channels for the doors, these components being fully integrated. The process is carried out by extruding a foamed profile with a channel through a first die therein having reduced dimensions where a protective shell is desired, co-extruding a plastic with said foamed profile in a second die to form a protective shell where the reduced dimensions occur, passing the co-extrusion though a calibration die, and then heating the co-extrusion at selected location where weather stripping is desired and then passing the co-extrusion through a final die where plastic weather stripping is extruded therewith and then cooling the integrated member.

In order to achieve high product quality and process reliability in a process for manufacturing an endless profile strand of soft plastic and/or rubber material fed to a supply storage for a sealing profile, edge protection profile or the like on a motor vehicle, it is provided that the manufacturing process be divided into two process sections which are carried out on two manufacturing lines that can be operated independently of one another.

Methods for manufacturing fabric-reinforced weatherstrip include incorporating a fabric application step into a process for making coated substrates. In one embodiment, a strip of the fabric from a roll of material may be applied directly onto a coating after it has been applied in a coat die to a foam profile, while the coating is still in the molten state. Alternatively, a fabric application plate may be attached to an upstream side of coating die with a fabric feed channel cut into the plate. The fabric follows the channel to contact and mate with the foam profile. The fabric applicator plate may be configured so as to exert pressure on only the part of the product where the fabric is being applied. Ultrasonic welding techniques may also be employed.

A non-contact extrusion nozzle head for applying sealant material to a U-shaped receiving channel defined by two panes of glass and a spacer frame for forming an insulated glass assembly. The non-contact extrusion nozzle head includes a nozzle head housing having a nozzle inlet channel extending into the nozzle head housing, and the nozzle head housing having a nozzle extension member mounted thereon. The nozzle extension member has a nozzle outlet channel formed therein which is connected to the nozzle inlet channel for receiving sealant material from the nozzle inlet channel. The nozzle head housing further includes an interior chamber formed in the nozzle extension member which has a nozzle outlet opening, the interior chamber being connected to the nozzle outlet channel for receiving sealant material therefrom. The nozzle outlet opening applies sealant material to fill the space defined by the U-shaped receiving channel between the two panes of glass and the spacer frame.

A method of welding mitered surfaces of frame sections made of plastic material and having incorporated therein a seal of weldable material extending along the frame sections and composed of an attachment foot and at least a sealing lip, for use in windows or doors, includes the steps of heat-welding mitered surfaces and adjoining frame section zones by means of a heated mirror while covering during welding operation an inner contour of the seal by at least one form-part that is positioned in and neighboring the miter plane and has a contour which substantially complements the inner contour of the seal. Subsequently, after removing the heated mirror from the miter corner and withdrawing the form-part the area of the seal, the mitered surfaces of the frame section are squeezed together.

A method for producing an extrusion molded product for automobiles, comprising the following steps:A synthetic resin injected into a first extrusion molding machine (21) is extruded through a first mold die (20) as a core material (3); the core material (3) passes through a first cooling tank (25), and then is bent by bending rollers (22) into a desired curved shape with a radius of curvature R1; the core material (3) is extended linearly, and goes into a second mold die (23); a thermoplastic elastomer injected in a second extrusion molding machine (24) forms seal portions (2) and seal lip portions (6) on a periphery of the core material (3); thereby forming a curved portion with a radius of curvature R2 on the extrusion molded product (1).
