摘要： A method for controlling the thickness of a continuous elongated element made of elastomeric material, applied according to coils wound on a forming support, comprises: advancing a head end (54) of the continuous elongated element (21) towards the forming support (11, 16); subjecting - during the advancement - the continuous elongated element (21) to a first stretching with a first stretch coefficient (K 1 ) before applying on the forming support (11, 16); subjecting - during the advancement - the continuous elongated element (21) to a second stretching with a second stretch coefficient (K 2 ) during the application on the forming support (11, 16). During the first stretching, a span (55) of the continuous elongated element (21) adjacent to the head end (54) is stretched with a supplementary stretch coefficient (K' 1 ) greater than the first stretch coefficient (K 1 ), in a manner so as to confer, also to the span (55) adjacent to the head end (54), a stretch and a section similar or substantially equivalent to those of the rest of the continuous elongated element (21) .

摘要： A method of applying a laminate to a tire includes pre-treating a portion of the tire and placing the laminate on at least the pre-treated portion of the tire. The method further includes placing an electrical heating element on top of the laminate and placing a pressure element over the electrical heating element and the laminate. The method also includes applying heat and pressure to the laminate using the electrical heating element and the pressure element to permanently adhere the laminate to the tire.

摘要： A method of assembling a tire having one or more reinforcements or supporting inserts in the sidewalls is provided. The reinforcements are positioned onto one or more air impermeable layers. One or more reinforcing plies are positioned over the reinforcing supports and suspended therebetween. A gas pressure is used to expand the one or more air impermeable layers away from the forming drum and against a reinforcing ply. As such, the creases or wrinkles in the one or more reinforcing plies can be avoided along with other non-uniformities such as deradialization and/or an uneven overlap where the ends of a ply are joined.
