Paper web decurling apparatus

Decurling apparatus for paper webs comprising,

• a stationary frame structure
• a horizontal shaft rotatably mounted in said stationary support,
• a comparatively large diameter support roll rotatably mounted on said rotatable shaft and having a resilient circumferential surface for supporting a paper web drawn from another roll,
• a pair of radially extending housings mounted in spaced parallel relation on the shaft adjacent opposite ends of said support roll thereon and fixedly secured on said shaft for rotation therewith,
• a relatively small diameter decurling roller rotatably supported in said housings parallel to the support roll and disposed to engage a paper web thereon,
• means for urging the decurling roller into pressure engagement with a paper web on the support roll selectively operable to adjustably vary the pressure of said decurling roller against the paper web and said support roll,
• and means selectively operable to rotate the shaft and and housings thereon about said shaft axis in either direction relative to the stationary frame structure and support roll and thereby position the decurling roller to engage a paper web on said support roll at any desired location circumferentially of the support roll.
