Abstract
A steam box includes a elongated steam-distribution chamber, regulator chambers set in a row next to the elongated steam-distribution chamber and covered on one side with a continuous perforated screen. Operating devices distribute the steam from the distribution chamber to each regulator chamber. The steam box is intended to feed steam through the perforated screen to the web, to heat it according to a desired profile. The perforated screen is secured along one long edge to hinge members and along the opposite edge to locking members and is arranged to be able to be opened, to permit access to the regulator chambers.
