A method for checking a continuous elongated element during the building of a tyre for vehicle wheels. A beam of an electromagnetic radiation is projected on a section of the continuous elongated element dispensed by a dispensing head and interposed between the dispensing head and a first contact area of the continuous elongated element with a radially outer surface of a tyre being processed. An image of a radiation reflected by the section is acquired. A first parameter related to the image is detected, and the first parameter is compared with a second reference parameter.

To improve durability by preventing breakage of each roller piece for a long time. It is a pressure roller for pressing a surface of a tire member made from an unvulcanized rubber member. The pressure roller has a support shaft and a plurality of elastically deformable roller pieces supported by the support shaft and arranged in the axial direction of the support shaft. Each roller piece has a pressing surface for contacting with the surface of the tire member. Each roller piece is independently rotatably supported by the support shaft.

A curing press for tires includes an upper cavity having a vertically separable upper housing and a top mold. A lower cavity is mounted on a base and forms an arrangement to provide mold height adjustment during curing. The base includes a bottom bolster structure and a bottom mold. An indexing lock ring is rotatably arranged with the bottom bolster structure for closing or opening of the top and bottom molds. The bolster structure includes squeeze cylinders having piston rods to provide mold height adjustment. A squeeze retract stop assembly is provided to restrict vertically downward movement of the bottom mold during a tire curing process. The press includes at least one locking lever and at least one indexing lock pin adapted to connect the at least one locking lever to lock holes in the bottom bolster structure wherein each lock hole corresponds to a particular mold height.
