- the carcass layer is a sheet material forming a skeleton of a pneumatic radial tire, and is constituted by covering a number of parallel aligned carcass cords with an unvulcanized coat rubber.
- the carcass cord may be either an organic fiber cord or a steel cord.
- the inner liner is a sheet material provided as the seal layer on the innermost layer of the pneumatic tire, and an unvulcanized rubber sheet such as butyl rubber having low air permeability is used.
- an unvulcanized rubber sheet such as butyl rubber having low air permeability.
- a film material made of a thermoplastic resin or a thermoplastic resin / elastomer composition that has the same degree of air permeability even if it is thinner than a rubber material, for the purpose of reducing the weight of tires, as a sheet material for an inner liner Some are used.
- the thickness of the film material is preferably in the range of 0.02-1.1 mm, which balances the weight reduction and the sealing property.
- the adhesive sheet is a sheet material inserted mainly for reinforcement around the bead portion.
- an unvulcanized rubber sheet or a sheet obtained by coating a reinforcing fiber fabric with an unvulcanized coated rubber is preferably used.
- the tie rubber layer is a sheet material used for strengthening adhesion when the adhesion between the carcass layer and the inner liner is low. Therefore, an unvulcanized rubber sheet having excellent adhesion is used for the tie rubber layer.
- a film material of a thermoplastic resin or a thermoplastic resin / elastomer composition is used for the inner liner, it is effective to use a tie rubber layer to strengthen the adhesion to the carcass layer.
- an adhesive layer may be added to the above film material.
- the winding method of forming a cylindrical tire casing on a forming drum using the above-described sheet material is determined according to the following A-C according to the winding order and combination of these sheet materials.
- A-C the winding order and combination of these sheet materials.
- the “pasting sheet + carcass layer” and the “pasting sheet + tie rubber layer” mean that a pair of left and right pasting sheets are pasted on the carcass layer before they are wound around the forming drum, respectively. The latter means that a pair of left and right sticking sheets are attached to the tie rubber layer and integrated.
- “pasting sheet + tie rubber layer + carcass layer” means that a tie rubber layer is pasted on the carcass layer in advance, and a pair of left and right pasting sheets is pasted on the tie rubber layer to be integrated. In this way, the sheet material is wound around the forming drum while pressing the sheet material in units of (1)-(3) with the pressure roller. To do.
- a drum having a band-shaped groove formed on the outer peripheral surface at a position corresponding to the winding position of the adhesive sheet is used.
- the width of the band-shaped groove may be large enough to store the sticking sheet.
- the depth of the band-shaped groove is preferably 0.3 to 1.5 times the thickness of the adhesive sheet, and more preferably 0.7 to 1.3 times. If the depth of the band-shaped groove is smaller than 0.3 times the thickness of the adhesive sheet, it is difficult to obtain the effect of the band-shaped groove described above. On the other hand, if it is larger than 1.5 times, a concave step will be generated, which is not preferable.
- a forming drum having an outer peripheral surface coated with an elastic layer may be used as the forming drum used in the present invention.
- the elastic layer is preferably made of a foamed resin such as polyurethane. Since the outer peripheral surface of the forming drum is covered with the elastic layer as described above, when the sheet material is wound around the forming drum while being pressed by the pressure roller, the step of the adhesive sheet is pressed onto the forming drum so that the adhesive sheet is pushed into the elastic layer. Disappears and the force S can be prevented from trapping air between the seats.
- the thickness of the elastic layer should be in the range of 0.5 to 5 times the thickness of the adhesive sheet. If the thickness of the elastic layer is smaller than 0.5 times the thickness of the adhesive sheet, it is difficult to eliminate the steps of the adhesive sheet. On the other hand, if the thickness of the elastic layer is more than 5 times the thickness of the adhesive sheet, the rigidity of the forming drum surface is reduced and the winding of the sheet material becomes unstable, which is not preferable.
- the pressure roller for pressing the sheet material against the forming drum may be a straight roller having a smooth outer peripheral surface, but preferably, a large number of hollow rollers are supported in parallel on a support shaft, and Mouth with these hollow rollers independently displaceable in the radial direction of the support shaft It is advisable to use a
- a hollow roller composed of a large number of weights is freely fitted and supported in parallel on the support shaft, and each hollow hole can be displaced independently in the radial direction of the support shaft.

- a roller configured as described above can be used.
- the distance at which the hollow opening can be displaced in the radial direction with respect to the support shaft is not particularly limited, but is preferably 0.3 to the thickness of the adhesive sheet. 1. Desirably 5 times.
- hollow rollers should have a reduced axial width of 5-10 mm. By reducing the width of the hollow edge as described above, each hollow edge presses the adhesive sheet in small width units, which makes it possible to push the adhesive sheet into the band-shaped groove or elastic layer with high dimensional accuracy. .
- the width of the hollow mouth is larger than 10 mm, it will be difficult to uniformly push the shell occupying sheet into the band-shaped groove or elastic layer, and if the width of the hollow mouth is smaller than ⁇ mm, the local area of the hollow mouth will be reduced. The pressure may be too high, causing deformation of the sheet material.
