A plant (2) for building tyres comprises a system for managing initial components (3); a system for managing the manufacturing of semi-finished products (4) starting from one or more initial components; a system for managing the building of a green tyre (5) starting from one or more semi-finished products; a system for managing the curing of said green tyre (6). The logical set of a control unit (8) for the plant (2) and/or of one or more from among control units (8a-8e) for the management systems (3-6) and/or of a automatic visual control system (7) is programmed for controlling at least two parameters, assigning to each of these a quality index (I), discarding a tyre being processed when a quality index (I) corresponding to said discard level (5) is assigned to at least one of said parameters and feedbacking the control result of at least one parameter in order to verify the quality index (I) of the parameters.

A method of manufacturing a pneumatic tire including forming a green case by cylindrically winding a tire component member which includes at least one layer of a carcass ply. A green tire is shaped by expanding the green case into a toroidal shape with the supply of a fluid into the green case so that the green case adheres to a tread ring arranged radially outside the green case. The green tire is subjected to vulcanization molding within a mold die. During the shaping of the green tire, the fluid is supplied in accordance with a pressure profile which changes in a stepwise manner. The pressure profile is set such that a former stage expansion rate in a former stage is set to slower than a final stage expansion rate in a final stage.

The present invention provides a method for extracting latex from a plant of the Asteraceae family and a method for cultivating a plant of the Asteraceae family, which allow such plants to be reused. The present invention relates to a method for extracting latex including a cutting step of cutting roots of a plant of the Asteraceae family in such a manner that the roots are partly left on the plant.

Provided is a method for producing a polyisoprenoid, which can increase natural rubber production by enhancing the rubber synthesis activity of rubber particles. The present invention provides methods for producing a polyisoprenoid using a gene coding for a cis-prenyltransferase (CPT) family protein, a gene coding for a Nogo-B receptor (NgBR) family protein and a gene coding for a rubber elongation factor (REF) family protein, specifically a method for producing a polyisoprenoid in vitro using rubber particles bound to proteins coded for by these genes, and a method for producing a polyisoprenoid in vivo using a recombinant organism (plant) having these genes introduced therein.

A mold for molding a tire tread comprises a plurality of mold segments. Each of the plurality of mold segments includes an integer number of tread pitch repetitions. The plurality of mold segments are structured to be coupled to each other end-to-end so as to form the mold such that the mold includes an integer number of tread pitches. The mold also includes at least one mold end segment positioned on at least one end of the mold and has a mold end segment length shorter than a length of each of the plurality of mold segments.

A method of manufacturing a pneumatic tire with surface fastener according to the present technology includes, while engaging a surface fastener provided with a plurality of first engaging elements and a sheet-shaped protective member provided with a plurality of second engaging elements that engage with the first engaging elements of the surface fastener, disposing the surface fastener in an unvulcanized tire so that a surface on a side opposite that of a surface on which the engaging elements are provided is closely fitted to an inner surface of the tire, and vulcanizing the unvulcanized tire provided with the surface fastener using a vulcanizer equipped with a vulcanization bladder.

A plant for building tires includes a system for managing initial components; a system for managing the manufacturing of semi-finished products starting from one or more initial components; a system for managing the building of a green tire starting from one or more semi-finished products; and a system for managing the curing of said green tire. The logical set of a control unit for the plant and/or of one or more from among control units for the management systems and/or of an automatic visual control system is programmed for controlling at least two parameters, assigning to each of these a quality index, discarding a tire being processed when a quality index corresponding to said discard level is assigned to at least one of said parameters and feedbacking the control result of at least one parameter in order to verify the quality index of the parameters.

A device and to a method for adjusting the height of a mold of a tire curing press, and to a tire curing press. The mold has at least two mold parts that can be positioned relative to each other. At least two double-acting fluid cylinders and at least one guide element are used. Positions are secured by at least one locking device.

A vertical position fixing of a treatment chamber inside a tire vulcanizing machine for the fastening of treatment chamber elements at least during a vulcanization process so that in the closed position at least one defined vertical distance H can be fixed, wherein fixing elements are provided on at least one treatment chamber element and are designed in such a way that a fixing which is releasable and absorbs the occurring forces is facilitated.
