摘要:
In a method for manufacturing a tyre casing (2), at least one electrically conducting wire (12), forming turns centred on a main axis (8) of the casing, and a connecting layer (10) are incorporated into the casing.
摘要:
In the method for retreading a tyre casing (2), a tread (6) is disposed on a carcass (4) of the casing, with a binding layer positioned between the tread and the carcass, and a strip (12) is tightened on the tread through multiple turns.
摘要:
In the method: - an electric current is passed through at least one wire (18) situated between a carcass (6) of a tyre casing and a tread (12), - a wire temperature value is calculated as a function of a value relating to the current, and - the current is controlled as a function of the calculated temperature value.
摘要:
The invention relates to a method for retreading a tyre casing comprising a step of heating. In the method for retreading a wheel tyre casing: - a wheel tyre casing is induction heated to soften a thermally malleable layer (14) situated between a tread (8) of the casing and a carcass (4) of the casing, • - the tread is removed from the carcass, and • - another tread is applied to the carcass. The invention also relates to a vehicle wheel tyre casing.
摘要:
Method for winding a rubber strip (24) onto a form of revolution (46), in which a strip (24) of predetermined length is formed, front-edge and rear-edge markings are applied thereto, and it is entrained toward the form (46), the front edge is placed on the form (46) and the form (46) is driven in such a way as to wind the strip (24) onto the form (46). During a first step, the drivings of the strip (24) and of the form (46) are synchronised in such a way as not to alter the length of the strip. During a second step, these drivings are controlled according to the angular position of the form (46) at the end of the first step and according to the position of the rear-edge marking so as to cause the relative speeds of travel of the rear-edge marking and of the rear-edge marking to vary and compensate for variations in the length of the strip (24).
