ABSTRACT:
A machine for shearing the pile of napped cloth includes a shearing bar and a shearing blade spaced by a variable gap from the bar. A control arrangement in accordance with the invention includes a sensing device for sensing the thickness of the base portion of the material and a further sensing device for measuring the variable gap. Signals from both sensing devices are compared and the output difference, if any, is used to actuate controls which adjust the variable gap.
