circular cutters
tools use a rotating circular blade.
the smallest devices ( power shears) are used for cutting single ply lays and for cutting fabric plies to length during manual spreading. depending on the size of the device it is possible to cut to a depth of about 10 mm.
the larger circular is used mainly for dividing a lay into sections. it is suitable only for cutting in straight lines or very gradual curves, in depths of up to about 150 mm.
