    Abstract: Particular embodiments of the invention include methods and apparatus for molding and/or curing an article. Particular embodiments of such methods include positioning a mold core centrally within mold outer portion to form an annular mold cavity between the mold outer portion and the mold core, the core including an outer ring having an outer surface for engaging the annular article, the outer ring being formed of a material capable of expanding and contracting with changes in temperature. Such methods also include heating the mold outer ring, cooling the core outer ring subsequent to the step of heating, whereby the core outer ring contracts relative to the article, and removing the article from the core outer ring.

    Abstract: Device for embedding a thread in a rubber profiled element comprising: a continuous thread feeder arranged on a structure, a moving support able to run along the structure between a raised and a lowered position. A hollow needle, comprising a canal in which the thread runs is fixed by one of its ends to the base of the moving support in the duct, and a tip at its other end capable of penetrating the rubber profiled element, a cutter arranged on the structure, comprising a rotary blade able to cut off the thread at a given distance from the tip of the needle upon each cycle of reciprocating movement of the needle. The cutter comprises a paddle arranged behind the cutting wire of the blade and intended to fold the tail around the tip of the needle just after the thread has been cut by the blade.

    Abstract: The present invention aims to provide a surface modification method for a rubber vulcanizate or a thermoplastic elastomer, which can impart excellent sliding properties and excellent durability against repeated sliding motion and can allow the surface to maintain the sealing properties, without using expensive self-lubricating plastics. The present invention relates to a surface modification method for modifying a rubber vulcanizate or a thermoplastic elastomer as an object to be modified, the method including: step 1 of forming polymerization initiation points on the object to be modified; step 2 of radically polymerizing a monomer, starting from the polymerization initiation points, by irradiation with LED light at 300 nm to 400 nm to grow polymer chains on a surface of the object to be modified; and step 3 of esterifying, transesterifying or amidating side chains of the polymer chains.
