<p>PURPOSE:To extrude hermetically sealing material, in which tubular sealing part is partially curved to anchoring part, by a method wherein a movable forming die for extruding the tubular sealing part is slid widthwise along the anchoring part of the hermetically sealing material in the midway of extrusion. CONSTITUTION:In the midway of the continuous extrusion of hermetically sealing material S, a movable forming die B is slid widthwise along the anchoring part S1 of the hermetically sealing material S so as to shift the position of a tubular sealing part S2, which is connected through a leg part 3 to the anchoring part S1 in order to extrude the hermetically sealing material S, in which the tubular sealing part S2 is partially curvedly connected to the anchoring part S1. And, when the portion, at which the tubular sealing part S2 shifts partially from the regular position, is arranged to the corner part of the opening of a car body, the flattening of the tubular sealing part S2 can be prevented from occurring.</p> |
