To suppress an undesired bulging shape of a weather strip caused by the contact with a feed roller in a manufacturing method for a weather strip wherein a core material is embedded in a foamed rubber part.
When the weather strip extruded from an extruder is allowed to run through a heating apparatus to be vulcanized while the undersurface of the weather strip is supported by a plurality of feed rollers arranged so as to leave an interval in an extrusion direction, the central support part 42 of each of the feed rollers 24a is constituted of annular protruded parts 48 divided into a plurality of parts laterally by a peripheral direction groove 46 in order to reduce the contact area with the rubber 15 of each of the feed rollers 24a. The weather strip W is fed while the undersurface of the core material embedded part is supported by a plurality of the protruded parts 48.
