Abstract: PURPOSE:To adjust a time for correcting a curl by a construction wherein a plurality of support elements supporting a web in a state of non-contact by jetting a gas are provided oppositely in a casing filled up with the gas of prescribed temperature and humidity and one side support elements are made movable. CONSTITUTION:A web 2 passes inside a casing 1 through an entrance 9 and an exit 10. The air having prescribed temperature and humidity is filled up in the casing 1. A floater device 5 disposed inside the casing 1 is constructed of three pairs of support elements 6 each comprising a fixed support element 6a and a movable support element 6b. Each of the support elements 6 is formed in a semi-cylindrical shape and round holes made in juxtaposition in the circumferential direction are disposed therein. The web 2 stretched around the support elements 6a and 6b is guided in a state of non-contact by the air blown out of the round holes. The jetted air is made to be the same in temperature and humidity with the air inside the casing 1. According to this constitution, the time of staying of the web 2 in the casing is adjusted by the motion of the movable support element 6b and the correction corresponding to the amount of curling can be conducted.
