摘要： In a fastening device in the position of a flexible support (1) scaling thetranslatory graduation carrier is arranged on a first element (2) of the machine and asensor device (5) is arranged on a second element (3 ) of the mobile machine relative tothe first element (2) of the machine. A device associates forcibly the graduation carrier (1)and the sensor device (5) in the direction of detection (10). A group of pairs of nozzlescomprises at least one pair (6, 7) of nozzles in communication with a compression systemis arranged in the sensor device (5). The nozzles (6, 7) of each pair of nozzles are locatedwith respect to the detection direction (10) on both sides of the division carrier (1) and atleast one nozzle (7) of the whole group is movable relative the sensor device (5), in thedetection direction (10). This mobility in the direction of the other nozzle (6) of the pair islimited by a stop (12) which ensures a minimum spacing relative to the other nozzle (6) ofthe pair. A member (11) force generator urges the movable nozzle (7) in the direction ofthe stop (12).
