Method and assembly for applying a tire component to a drum

A method for applying a tire component from an apply member onto a receiving member, wherein the tire component comprises a leading edge, a trailing edge and a first longitudinal edge and a second longitudinal edge extending between the leading edge and the trailing edge, and wherein the leading edge is non-uniform or non-linear with respect to the shape of the trailing edge, wherein the method comprises the steps of:

• a) receiving the tire component on the apply member;
• b) detecting a plurality of leading endpoints at the leading edge, wherein said leading endpoints are distributed over the length of the leading edge at equal intervals;
• c) for each leading endpoint, determining a trailing endpoint at the trailing edge that together with the respective leading endpoint forms a pair of endpoints, such that the interval between each set of two directly subsequent trailing endpoints on the trailing edge is equal to the interval between the set of the two respective, directly subsequent leading endpoints on the leading edge;
• d) determining a relative positioning between the leading endpoint and the trailing endpoint for each pair of endpoints;
• e) driving the apply member at an apply speed to transfer the tire component in a transfer direction onto the receiving member while driving the receiving member at a receiving speed;
• and
• f) splicing the trailing edge to the leading edge on a building drum;
• wherein the leading endpoint and the trailing endpoint of at least one of the pairs of endpoints are spaced apart on the apply member in a lateral direction transverse or perpendicular to the transfer direction,
• wherein during step e) the apply member and the receiving member are moved relative to each other in the lateral direction when transferring said at least one pair of endpoints to reduce the spacing between the leading endpoint and the trailing endpoint of said at least one pair of endpoints in said lateral direction, and
• wherein a ratio between the apply speed and the receiving speed is adjusted when transferring said at least one pair of endpoints to improve the relative positioning of the leading endpoint and the trailing endpoint of said at least one pair of endpoints for splicing.
