Abstract
A curtain coating width changing device in which the width of the backup device at a coating portion can be rapidly changed continuously and smoothly. A backup roller supports a continuously running web. A pair of collar members is provided at respective opposite edge portions of the backup roller and is movable in the axial direction of the backup roller, the collar members lying on an extension of a top portion of the backup roller. A pair of spacers is provided in the spaces between the roller and corresponding ones of the collar members so as to form an extended surface of the top portion of the backup roller and to fill the spaces. Each of the collar members has a spiral end surface, whereby the effective axial length of the extended portion of the top portion of the roller can be adjusted by rotation of the spacers.
