reed 120 and includes two rear stepped wheels 42 that are mounted to the underside of clamping roller mount 40 clamping roller mount 40 operates in conjunction with clamping air cylinder 34 specifically with clamping arm 36 and clamping wheels 38 to secure the apparatus to reed 120 air flowing through clamping air cylinder 34 forces clamping arm 36 against the face of reed 120 because the flow of air actuates a clamping action that continues during the operation of the apparatus the apparatus remains in proper vertical alignment on reed 120 throughout the cleaning process without the cooperative relationship between clamping air cylinder 34 and clamping roller mount 40 the tension on warp yarn sheet 122 would cause the apparatus to rise off of reed 120 during operation thereby negatively impacting the efficient cleaning of reed 120 and effectively negating the cleaning of auxiliary air nozzles 124 clamping wheels 38 located on clamping air cylinder 34 and stepped wheels 42 located on clamping roller mount 40 are free to rotate along the front and rear sides of reed 120 respectively with reed 120 assuming a functional role as a track along which the apparatus traverses in addition to aiding in the movement of the apparatus stepped wheels 42 provide a further benefit to the apparatus by aligning themselves with the upper edge of reed 120 and.
