A weather strip including a bottom wall, a first lateral wall and a second lateral wall and in which an angle between the bottom wall and the first lateral wall is constant and an angle between the bottom wall and the second lateral wall is partially varied in a longitudinal direction is manufactured. The method includes: a first step of pre-forming the angle of the first lateral wall and the angle of the second lateral wall to be constant and equal to or larger than final maximum angles; a second step of regulating a boundary between the bottom wall and the second lateral wall from moving toward the first lateral wall by a regulating member; a third step of partially varying the angle of the second lateral wall by a movable roller; and a fourth step of forming the angle of the first lateral wall by a fine-movable roller.

A metal band as an insert for trim strips, sealing strips, or edge protection strips, in particular for motor vehicles, wherein the surface is profiled at at least one flat side of the band to increase the adhesion between the metal band and a plastic or rubber coating. These metal bands can also be designed with a plurality of openings following one another in the longitudinal direction of the band, in particular cut and roll-stretched or punched slots.

A glass run includes: a bottom wall; a vehicle-outer-side side wall; and a vehicle-inner-side side wall. The bottom wall, the vehicle-outer-side side wall and the vehicle-inner-side side wall configure a basic framework being attached to a door frame groove portion formed in a door frame. The glass run guides an up and down movement of a door glass. A thick portion that protrudes to a vehicle inner side, is in sliding contact with the door glass, and has a higher hardness than that of the vehicle-outer-side side wall is formed on a vehicle inner side of the vehicle-outer-side side wall. When a thickness of the thick portion is set to t1 and a sum of thicknesses of the thick portion and the vehicle-outer-side side wall is set to T, t1 is 0.4 T or more and 1.0 T or less.

Vehicle roof having a roof skin which encloses a roof cutout, in which a fixed roof element and a roof opening are formed, by an inner edge and to a roof opening system having a lid element and displacement kinematics. On the inner edge of the roof skin, a weatherstrip arrangement is disposed which has a longitudinal leg and a front transverse leg and a rear transverse leg on either side. Starting from the front transverse leg, the longitudinal legs each comprise a first profile portion and a second profile portion, which interacts with the fixed roof element and is wider than the first profile portion. The longitudinal legs each comprise a third profile portion, which is disposed rearward of the second profile portion. The third profile portion is narrower than the second profile portion and transitions into the rear transverse leg.

Methods of forming an article from a molten plastic composition comprising a polymer and a blowing agent. The methods include injecting the molten plastic composition into a mould, allowing the plastic composition to form a first solid skin adjacent to an in contact with a first cavity-forming surface of the mould and a second solid skin adjacent to and in contact with a second cavity-forming surface of the mould, and then opening the mould before the molten plastic composition between the first and second solid skins in at least one portion of the circumference of a region of the mould cavity defining an annular cross-section of the cavity has solidified.

A seal assembly includes a body portion defining a mounting channel for receiving a vehicle flange. A base of the body portion defines an outer surface of the body portion with the outer surface defining a first axis of curvature adapted to correspond with a contour of the flange. The seal assembly further includes a sealing lip portion co-extruded with the body portion and defining a notch having a notch configuration, an element disposed in the notch and pre-formed to have an element configuration corresponding to at least a part of the notch configuration, and a molding material molded to a back surface of the element, secured to the sealing lip portion within the notch, and extending across the notch, with the element and the molding material defining a contour lip portion that in combination with the sealing lip portion defines an external sealing lip of the seal assembly.

A plug is disclosed that reduces a potential for damage to a cap or bright strip of a weatherstrip assembly. The plug is preferably an elongated member having a cross-sectional first dimension that extends between and contacts an indented, transition region of the weatherstrip body and an inner surface of the cap.
