## Abstract

The curing press (2) for a tire blank comprises: a trough (4), a cover (6) connected to the trough by means of sliding guide members (8), the cover and the trough each being pivotably mounted on these members. The cover (6) is, moreover, pivotably mounted on an axle (24) guided slidably with respect to the trough.

## Claims

### Claim 1

A curing press for a tire blank comprising:
a trough;
a cover connected to the trough by sliding guide members, the cover and the trough each being pivotably mounted on these members, the cover being pivotably mounted on an axle guided slidably with respect to the trough; and
at least one actuator capable of pivoting the sliding guide members with respect to the trough and directly pivotably mounted on the sliding members.

### Claim 2 (depends on 1)

The press according to claim 1, wherein the axle extends lower than an axle connecting the cover to the sliding guide members.

### Claim 3 (depends on 1)

The press according to claim 1, further comprising a rail for guiding the axle.

### Claim 4 (depends on 1)

The press according to claim 1, further comprising an element for rectilinearly guiding the axle.

### Claim 5 (depends on 1)

The press according to claim 1, further comprising an element for vertically guiding the axle.

### Claim 6 (depends on 1)

The press according to claim 1, further comprising a connecting rod rigidly fixed to the cover and bearing the axle.

### Claim 7 (depends on 1)

The press according to claim 1, wherein the axle extends on one and the same side of the press as the actuator.

### Claim 8 (depends on 1)

The press according to claim 1, wherein the sliding guide members each comprise a rod slidably mounted in a sleeve.

### Claim 9

A method for opening a curing press for a tire blank, wherein:
a cover of the press is slid upwardly with respect to a trough of the press;
members for connecting the cover to the trough are tilted by means of at least one actuator directly pivotably mounted on the members; and
the cover is tilted with respect to the connecting members.
