Abstract: A method and equipment for cutting slivers of continuous filaments of textile material into tuft fibres adapted for further spinning and twisting operations, wherein a continuous sliver formed by said filaments is advanced at a high speed in a plane and laser ray pulses are focalized on said plane in the form of a narrow window having a length greater than the width of said sliver, in order to cut the same into a plurality of tuft fibres having a predetermined length.
