A green tyre (2) for bicycles is built, comprising at least one carcass ply (4) having axially opposite end flaps (4a) engaged with respective bead cores (5) and a tread band (6) applied in a radially outer position around said at least one carcass ply (4). The built tyre (2) removed from the building drum, is profiled so as to translate the tread band (6) in a radially outer direction with respect to the bead cores (5), so as to impart a cross-sectional convex profile to the tyre (2) in a radially outer direction. The profiled tyre is engaged by means of a transfer member (31) comprising a gripping device (30) which retains it at the radially outer surface (2b) so as to maintain said cross-sectional convex profile in a radially outer direction.

A tire vulcanizing system (100) is provided that optimizes the service life of guidance means and preserves the thermal stability of the vulcanization.

The profiled tire is engaged by means of a transfer member (31) comprising a gripping device (30) which holds it hanging and loads it into a vulcanisation mould (101) by axially positioning an axial centreline plane (M) of the green tyre at an axial reference (51) arranged at a predetermined height along a reference axis (K) of a central body (103) of the vulcanisation mould (101).

Methods for controlling curing apparatuses for tyre production, wherein the curing apparatuses are adapted to work on green tyres to obtain corresponding finished tyres, by acquiring, through a processing unit, initial parameters describing at least one of the shape and dimensions of the finished tyres; computing, through the processing unit, as a function of the initial parameters, first parameters describing the green tyres, the first parameters having at least one parameter representative of an axial height of the green tyres; acquiring, through the processing unit, second parameters describing the curing apparatuses, said second parameters having one or more parameters representative of dimensions of the curing apparatuses; computing, through the processing unit, third parameters as a function of the first parameters and the second parameters, the third parameters having one or more parameters representative of positions taken by movable members included in the curing apparatuses; generating, through the processing unit, as a function of the third parameters, control signals for controlling the movable members of said curing apparatuses and for obtaining said finished tyres starting from the green tyres; sending the control signals from the processing unit to the curing apparatuses. Also disclosed are a curing line operating in accordance with the methods, a processing unit programmed for implementing the methods, and an electronic unit included in the processing unit.

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 tire vulcanizing method includes a tire removal step for removing a vulcanized tire from a mold. The tire removal step includes a stage in which upper and lower side molds are moved inward in a tire axial direction so as to deform the vulcanized tire in a direction in which a bead width of the vulcanized tire is decreased, and a stage in which, in the deformed state of the vulcanized tire, the segments are moved outward in a tire radial direction so that the segments are removed from the vulcanized tire.

A handling device for tires having at least one extension arm, wherein the at least one extension arm is secured with a first extension arm pivot location to a receiving member in such a manner that a pivoting of the at least one extension arm relative to the receiving member is supported and the at least one extension arm has a second extension arm pivot location so that at least one gripping tool is coupled to the at least one extension arm. At least a second gripping tool is coupled to the second extension arm pivot location, and the at least two gripping tools can be pivoted relative to at least one extension arm pivot location. The invention further relates to a method for carrying out a loading and unloading cycle with tires of a tire vulcanization machine.

The present invention relates to an aqueous, solids-containing dipping bath composition for treating reinforcing inserts for rubber products comprising the following components or consisting of these components, (A) at least one blocked MDI mixture, the MDI mixture comprising MDI oligomers of formula (I), n being a whole number from 1 to 8, and MDI monomers; (B) at least one resorcinol-formaldehyde latex; and (C) possibly at least one additive, wherein the dipping bath composition is essentially free of epoxides. ##STR00001##

A method of molding a green tire having a first and second bead area is described herein, wherein the method includes the steps of: inserting a tire clamping device inside a tire bladder and then inserting the tire clamping device and the bladder into the green tire, aligning the outer surfaces of the tire clamping device into engagement with a respective bead area of the tire so that each tire bead area is clamped between a respective upper and a lower mold ring and the tire clamping device during cure. A tire clamping device includes an inner portion, and a plurality of segments connected to the inner portion, wherein the tire clamping device has a closed position wherein the plurality of segments together forms a first and second ring for engagement with the bead areas of the tire so clamp the bead areas between the clamping device and the mold rings during cure.
