Device and method for butt-splicing strip members

A device for butt-splicing strip members for tire components, comprising a first clamp and a second clamp arranged for clamping a first end of a first strip member and a second end of a second strip member, respectively, wherein at least one of the first clamp and the second clamp is movable along a butt-splice direction into a butt-splicing position in which the first clamp and the second clamp are arranged to be opposite to each other in said butt-splice direction for butt-splicing the first end of the first strip member and the second end of the second strip member in the butt-splice direction, wherein the first clamp comprises a first upper clamp member and a first lower clamp member for in cooperation clamping the first end, wherein the second clamp comprises a second upper clamp member and a second lower clamp member for in cooperation clamping the second end, wherein the first lower clamp member projects beyond the first upper clamp member in the butt-splice direction towards the second clamp over a first overlap distance and wherein the second upper clamp member projects beyond the second lower clamp member in the butt-splice direction towards the first clamp over a second overlap distance.
