Abstract: 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.

Abstract: The invention relates to a method of making a join between two strands (10, 20). The method comprises cutting each of the two strands at an angle relative to its longitudinal axis so as to obtain a cut surface (13, 23) on each strand. The cut surfaces of the two strands are joined by mirror welding.
