Автор: Alfredo Balini, Stefano Cazzanti
Принадлежит: Pirelli Tyre SpA

In a method for manufacturing tyres for vehicle wheels, a green tyre, once formed, is transferred into a vulcanisation mould and pressed against the holding walls of a moulding cavity. Concurrently with the pressing step, a fluid present between the green tyre and the holding walls is evacuated through vent valves. The tyre is brought into contact with the closing head of each valve so as to push it toward a closed position of the valve itself. The closing head has a distal portion facing the moulding cavity and includes at least one grip element for the tyre blend, so that the closure member is pulled toward the open position while the moulded and cured tyre is moved away from the inner surface of said moulding cavity.

Device for producing a tread for a vehicle tire

Номер: US20120160423A1
Автор: Udo Frerichs
Принадлежит: Continental AG

A tread for a vehicle tire has an electrically conducting layer axially inside a portion of a first, radially outer rubber layer of the tread. The electrically conductive layer extends from a second, radially inner rubber layer of the tread on the radially inner side of the tread rubber material up to a ground contact surface of the tread. During the tire build-up, an accumulation of rubber material of higher electrical conductivity is built on a first rubber layer of higher electrical conductivity. The accumulation is formed into a ridge web and then less-conductive rubber is laid laterally next to the web, such that the web of rubber material reaches up to the ground contact surface in the finished vehicle tire. The web is shaped by forming rollers, by baffles, or by a forming ring with a corresponding shape.

A method for manufacturing a pneumatic tire having a carcass ply of cords rubberized with topping rubber, comprises a process for building a raw tire on an annular surface of an uninflatable core mold, and a process for vulcanizing the raw tire built on the core mold by heating the raw tire together with the core mold. The process for building the raw tire comprises making the raw carcass ply by rubberizing the carcass cords with the raw topping rubber. The carcass cords are made of polyethylene terephthalate or alternatively polyethylene naphthalate. The dry heat shrinkage percentage of the carcass cords before subjected to the vulcanizing process is 1 to 3% at 180 degrees C. The Mooney viscosity of the raw topping rubber is 35 to 70 (ML1+4, 130 deg. C.).

A tire vulcanization mold can be configured to provide stable ventilation. For example, a tire molding surface has a ventilation groove having a rectangular shape in plan view. A blade has upper end, contact and communication sections. The upper end section thickness is smaller than a groove thickness. The contact section below the upper end section contacts both thickness-direction-facing side faces of the groove. The communication section communicates between a ventilation hole, and a small gap is formed between the groove and the upper end section. Alternatively, the blade has a groove section formed in at least one side face that faces in a blade thickness direction and extends between upper and lower blade ends to form a small gap between the groove and groove section. Air and gas pass through the gap and the communication section and vent to an exterior of the mold through the ventilation hole.

Tires in use wear in a host of ways. One negative manner in which tires, especially truck tires, may wear is in an irregular fashion. When this phenomenon happens, the tread of the tire may become unusable, forcing the user to replace the tire, which is undesirable. This patent application poses a new and useful way of preventing irregular wear involving the use of hidden sipes or tread blocks. In some embodiments, these hidden sipes or tread blocks are found in tread blocks or ribs adjacent other tread blocks or ribs that have been determined to be susceptible to irregular wear. In other embodiments, the hidden sipes or tread blocks are formed by a sipe blade that has a connecting member to which two y-branched members are attached, and further comprising dividing members that connect between the y-branched members.

A tire manufacturing method to obtain a base tire superior in uniformity when the base tire has a cushion gum applied thereon. In this process of tire manufacture, the thickness from a belt, which is located in the outermost layer of the base tire having an application surface for the cushion gum, to the application surface is measured along the circumference of the base tire so as to detect a maximum thickness position. Then the circumferential winding of the cushion gum extruded from an extrusion molding unit is started from the maximum thickness position.

Принадлежит:

A rubber strip is transported to a molding drum. At this stage, a cutter cuts the rubber strip into a predetermined length. If a sensor detects the finishing end of the rubber strip when the rubber strip is transported, a sucker, which transports the rubber strip while drawing the rubber strip, is temporarily stopped or the movement speed of the sucker is decreased. As a result, a top portion of the rubber strip is extended in the longitudinal direction of the rubber strip. This compensates for the amount of shrinkage of the rubber strip after extrusion, thus restraining shrinkage of the rubber strip. 1. A winding method for a bead filler for a tire including winding a rubber strip of a predetermined length in an annular shape and joining opposite ends of the rubber strip to each other ,wherein, prior to the joining of the opposite ends of the rubber strip, at least one of the opposite ends of the rubber strip is extended.2.
