  • Method and apparatus for removing a thin coating from a fabric
    Patent number: 6234871
    Abstract: An apparatus for removing a thin film of material from a portion (23) of a sheet of fabric (22) and its method of operation, includes a grinder wheel (19) spaced from a nip roller (29) which is carried by an arm (32). The initial spacing between the grinder wheel (19) and the nip roller (29) is established by an adjusting mechanism (37) which pivots the arm (32), that spacing being determined by the expected thickness of the fabric (22). Pinch rollers (27) move the fabric (22) through the space, and a thickness-sensing wheel (44) rides on the fabric (22) upstream of the nip roller (29). Upon a change in the thickness of the fabric (22), a sensing arm (45) which carries the sensing wheel (44) pivots which, through a link arm (54), pivots a regulator arm (61) which carries a follower roller (70) that rides on the arm (32). Such allows the nip roller (29) to move toward or away from the grinder wheel (19) dependent on the thickness of the fabric (22) sensed by the movement of the sensing wheel (44).
