Disclosed is a method and an assembly for applying a tire component onto a receiving member. The method includes the steps of: receiving the tire component on the apply member; detecting a plurality of leading endpoints at the leading edge and detecting a plurality of trailing endpoints at the trailing edge in-line with the leading endpoints in the longitudinal direction; determining the distance in the longitudinal direction between the leading endpoint and the trailing endpoint for each pair of endpoints; driving the apply member at an apply speed in a transfer direction to transfer the tire component onto the receiving member while driving the receiving member at a receiving speed; and adjusting the ratio between the apply speed and the receiving speed during the transfer of the tire component in the order in which the pairs of endpoints are spliced to improve the relative positioning of each pair of endpoints for splicing.

A method for winding a rubber strip onto a form of revolution includes steps of: forming a strip of predetermined length, applying front and rear edge marks to the strip, driving the strip towards the form, arranging a front edge of the strip on the form, and driving the form to wind the strip onto the form. In a first phase, the driving of the strip and the driving of the form are synchronized so as not to modify the length of the strip. In a second phase, the driving of the strip and the driving of the form are controlled depending on an angular position of the form and on a position of the rear edge mark, in order to vary relatively a displacement speed of the rear edge mark and a displacement speed of the front edge mark, to compensate for variations in the length of the strip.

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.

A system for making a tire tread includes an extruder, a roller die having a first axis of rotation, and a conveyor that receives a round strip (or noodle) of green rubber from the extruder and feeds the strip of green rubber to the roller die. The system further includes a drum having a second axis of rotation, wherein the roller die is configured to apply the strip of green rubber to the drum. The system also includes a controller, wherein the controller is configured to control a translation of the roller die in a first direction parallel to the first axis of rotation. The controller is configured to control a roller die rotation speed and a drum rotation speed, and the controller varies at least one of the roller die rotation speed and the drum rotation speed during translation of the roller die.

A distance measure between a beginning and an end of a material strip wound onto a body in a tangential direction can be determined by creating a height profile of a surface of the material strip, which covers the beginning and the end of the wound material strip in the tangential direction. If a position value of the beginning of the material strip is determined in the created height profile, the distance measure can be determined using this position value and the height profile covering the end of the material strip.
