HYDRAULIC TIRE CURING PRESS APPARATUS AND A METHOD FOR ADJUSTING MOLD HEIGHT IN A HYDRAULIC TIRE CURING PRESS
A curing press for tires that comprises: an upper cavity part having a vertically separable upper housing (9) and a top mold (11); a base having a lower cavity part that forms an arrangement to provide mold height adjustment during curing. The base comprises a bottom bolster structure (20) and a bottom mold (22). The bottom bolster structure comprising: ring means rotatably arranged with said bottom bolster structure, to facilitate closing or opening of said top mold and said bottom mold; the bolster structure comprises squeeze cylinders (24) having means to provide mold height adjustment. A squeeze retract stop assembly is provided to restrict vertically downward movement of said bottom mold during a tire curing process. The press comprises at least one locking lever (34) and at least one indexing lock pin (35) that is adapted to connect said lever (34) to lock holes (20a) in said bottom bolster structure (20) wherein each lock hole corresponds to a particular mold height.

METHOD FOR CHECKING A CONTINUOUS ELONGATED ELEMENT DURING THE BUILDING OF A TYRE FOR VEHICLE WHEELS AND APPARATUS FOR BUILDING A TYRE FOR VEHICLE WHEELS
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.

Application system and method for applying a sealing agent to the inner surface of a pneumatic tire
An application system and method for applying a sealing agent to the inner surface of a pneumatic tire includes: rotating, by means of a support device, the pneumatic tire about an axis of rotation; applying a layer of sealing agent to the inner surface of the pneumatic tire by means of a dispensing head arranged within the pneumatic tire itself; pressing, by means of a pressure roller, the just applied layer of sealing agent against the inner surface of the pneumatic tire; pushing the pressure roller against the just applied layer of sealing agent by means of an actuator which generates a force having a desired value; determining, by means of a force sensor, a measured value of the force generated by the actuator; and cyclically varying the force generated by the actuator as a function of the measured value of the force.
APPLICATOR UNIT, TIRE BUILDING DEVICE AND METHOD FOR APPLYING A STRIP TO A DRUM
The invention relates to an applicator unit, a tire building device and a method for applying a strip to a drum, wherein the applicator unit comprises an applicator roller and a cutter, wherein the applicator roller comprises a roller body that is rotatable about a roller axis for applying the strip to the drum in an application direction perpendicular to said roller axis, wherein the applicator roller and the cutter are configured to cooperate for cutting the strip on the applicator roller along a helical cutting path about the roller axis.
