Abstract: A continuous elongated element of elastomeric material is produced through an extruder at a linear delivery speed and directly fed onto a moving surface of a conveyor without interposition of other devices. The continuous elongated element is advanced on the moving surface along a predetermined direction and at a linear advancing speed different from the linear delivery speed until a proximal end of the conveyor. Subsequently, the continuous elongated element is applied onto a forming support which rotates relative to the proximal end of the conveyor at a peripheral speed different from the linear delivery speed, so as to deform the continuous elongated element and apply it in the form of wound coils onto the forming support in order to form a component of elastomeric material of a tyre.
