A dosage device for extruding a monocomponent or a bicomponent polymeric product, particularly for an automatic machine for forming a spacer frame, includes a first dosage assembly and a separate second dosage assembly for the dosage and feeding of the product, which can be activated, in a first feeding step and in a third feeding step, alternately so that one of them provides continuity of flow to an extrusion nozzle while the other one is in the reloading step. The first and second dosage assemblies are activated, in a second swapping step that is intermediate with respect to the first and third feeding steps, simultaneously and jointly, one of them having a flow-rate ramp that passes from the steady-state value to zero and the other one complementarily having a flow-rate ramp that passes from zero to the steady-state value.

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.

The profiled element (1) comprises: one main portion (2) defining a holding surface (2a) for a central panel (3) of a door/window (4), the main portion (2) being adapted to form a perimeter frame (5) of the door/window (4); one retaining portion (6) which defines an abutment surface (6a) of the central panel (3) and is adapted to fasten the central panel (3) to the perimeter frame (5); and non-removable connection means (7) which connect the main portion (2) to the retaining portion (6) and are adapted to allow the movement of the retaining portion (6) between a raised configuration, wherein it frees superiorly the holding surface (2a), and a retaining configuration, wherein it faces the holding surface (2a).

The present invention relates to a method for producing a shaped article, a shaped article obtained therefrom and the use of the shaped article in vehicle door intrusion beams, structural inserts in body in white, bumper beams, instrument panel cross members, seating structural inserts and front-end module structures.

A method for producing an extrusion molded product, wherein the method uses a holder (6) for feeding a core material (11), the holder (6) being provided with cutting guide holes (7) through which cutting blades (2) go to form grooves (12) in the core material (11); when rotary bodies (3) provided with the cutting blades (2) start rotating, the core material (11) and the holder (6) stand by at a predetermined standby position that does not enable the cutting blades (2) to cut the core material (11); and when the rotation speeds of the rotary bodies (3) reach predetermined rotation speeds, the holder (6) is or the rotary bodies (3) are moved so that the cutting blades (2) can start cutting the core material (11) proceeding through the holder (6), and then the cutting blades (2) form a plurality of grooves (12) in the core material (11).

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).

The weather strip configured to be attached to the automobile body opening portion is an elongated member having a length configured to correspond to a side portion and a corner portion of the automobile body opening portion and includes a hollow sealing portion. A surface of the sealing portion corresponding to a floor-side side portion and a surface of the sealing portion corresponding to a floor-side corner portion are continuous to each other. A wall thickness of the sealing portion corresponding to the floor-side side portion is set to be smaller than a wall thickness of the sealing portion corresponding to the floor-side corner portion. The sealing portion corresponding to the floor-side side portion includes a portion having a smallest wall thickness among the entire sealing portion.
