Abstract: 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.

Abstract: A method and an apparatus for correcting a feeding distance of a strip or cutting, involves feeding the strip over the feeding distance in a feeding direction towards a cutting line that extends at an oblique cutting angle to the feeding direction; detecting a lateral position of a first longitudinal edge of the strip in a lateral direction perpendicular to the feeding direction; wherein, when the detected lateral position is offset over an offset distance in the lateral direction with respect to a reference position for the first longitudinal edge at the measuring line, and adjusting the feeding distance with a correction distance that is related to the offset distance in a ratio that is defined by the cutting angle.
