Abstract
A method for cutting along a cutting line of a laminate, including a first and a second textile layer surrounding an intermediate layer of a porous elastic material. The laminate is pressed together in a local nip between an ultrasound emitting element and a counteracting element, and the laminate is moved in the cutting line through and past the nip during ultrasound cutting of the laminate simultaneous with ultrasound welding of the first and the second surface layers to each other in order to form a smooth, rounded, continuous edge joint between the surface layers at a free edge of the laminate.
