The curing press for a tire blank comprises: a mold and inductors capable of heating the press by electromagnetic induction, each inductor comprising a core (36) comprising two feet (40) having respective undersides (60) which are flat and inclined in relation to one another.

A tire vulcanization mold including a sector mold divided into a plurality of pieces along a circumferential direction of a green tire, the sector mold configured to vulcanization mold a tread portion of the green tire into a predetermined shape, and an upper mold and a lower mold disposed on both sides of the green tire so as to sandwich the green tire therebetween in an axial direction of the green tire, the upper mold and the lower mold configured to vulcanization mold a side portion of the green tire into a predetermined shape. The sector mold has a relief groove in a vicinity of a fitting portion between the sector mold, and the upper mold and the lower mold.

A method and the device are used to control valves. The valves are arranged in the region of lines for a fluid. At least one first valve is in the form of a control valve arranged in the region of a primary line. At least one second valve is in the form of a switching valve. At least one branch is arranged downstream of the control valve in the region of a direction of flow. At least two secondary lines extend downstream of the branch. Each secondary line has one of the switching valves. The valves are connected to a control unit which coordinates the function of the valves.

An embodiment of the present invention provides a technique for minimizing the deformation of the shape of a kerf by improving the durability of a blade used in forming the kerf during tire vulcanization. A 3D kerf-forming blade according to an embodiment of the present invention is installed in a tire vulcanization mold for forming a kerf and includes a frame formed in a shape of a plate having a wave shape in a cross section horizontal to a thickness direction and a support formed in a shape of a bar having one side connected to the frame and the other side connected to another frame.

Systems for depositing coatings onto surfaces of molds and other articles are generally provided. In some embodiments, a system is adapted and arranged to cause gaseous species to flow parallel to a filament array. In some embodiments, a system comprises one or more mold supports that are translatable.

A method and device for manufacturing the tire are provided. For each tire obtained by feeding green tires having an identical specification into an identical vulcanizer, using an arrangement mechanism, with circumferential positions of the green tires varied with respect to the vulcanizer and vulcanizing the green tires, a storage unit stores characteristic value data of at least one of a UF or DB value and feed position data identifying the circumferential position of the green tires, a calculation unit calculates, based on the stored data, the circumferential position of the green tires with respect to the vulcanizer at which a characteristic value related to the characteristic value data is brought within a tolerance range, and feeding using the arrangement mechanism, into the vulcanizer, the green tire to be newly vulcanized while adjusting the green tire to the circumferential position with respect to the vulcanizer being calculated.

A combination of first and second plugs for a tire mold includes associated first and second receivers/jackets. Fasteners secure the receiver to an associated tire mold. A securing member extends from the receiver into the cavity of the first receiver to retain the first plug therein. The first plug is contoured and dimensioned for mating receipt in the first receiver cavity. The second plug is likewise contoured and dimensioned for mating receipt in the associated second receiver cavity, but will not be accepted in the first receiver. A tool is provided to facilitate insertion and removal of the first and second plugs, and limit the potential for damage to the associated tire mold.

A tire vulcanizing apparatus includes a mold having a tread mold including a plurality of segments arranged in a tire circumferential direction, and upper and lower side molds. Each of the segments includes an upper segment portion and a lower segment portion which are divided up and down. The apparatus includes a segment supporting unit which supports the upper segment portion and the lower segment portion so as to be movable to the same side in a tire radial direction and opposite sides to each other in a tire axial direction.

Tire mold maintenance and repair systems and related methods are disclosed. According to an aspect, a mold maintenance and repair system includes a mold holder. The mold holder is configured to releasably attach to a support structure and to hold a mold. The mold comprises contoured upper portion for molding an item and an attachment lower portion for attaching to the mold holder.

An upper side mold is lowered without mechanical combination between the mold and a lowering force application device.

A tire vulcanizing apparatus 1 includes a mold 2, a lowering force application device 25, and an attachment 4. The mold 2 includes a tread mold 6, an upper side mold 7U, and a lower side mold 7L. The lowering force application device 25 is disposed above the mold 2 and includes a rod 25a extending downward. The attachment 4 is fixed to an upper portion of the mold 2 without mechanical combination with the rod 25a. The attachment 4 includes a body 35 and an upward-downward movable portion 36 fixed to the upper side mold 7U. The upward-downward movable portion 36 lowers the upper side mold 7U upon receiving a lowering force F from the rod 25a.
