ABSTRACT:
Shearing operations on textile pile fabrics may be repeatably controlled precisely by controlling operating parameters of the shearing machine to maintain constant the average number of times each pile loop of the fabric is cut by the shearing blades of the shearing cylinder, which is accomplished by calculating a numeric value representing cuts per pile loop as a function of the rotational speed of the cylinder, its number of shearing blades, the widthwise dimension of the nose surface of the fabric rest, and the fabric traveling speed, and selectively adjusting one or more of these parameters as necessary to achieve the desired number of cuts per fabric loop.
