A cleaning device (10) for a threaded shaft (12) having a cleaning member (34) having a threaded recess (42) received on the shaft (12) and extending partially around the shaft (12) with the threads (44) of the cleaning member (34) meshing with the threads (14) of the shaft (12).

Cleaning device for a threaded shaft

A folder (58) of the type having a folding cylinder (16) cooperating with a jaw cylinder (20) to cut and fold a ribbon of paper (14) into a folded product (14') provided with a guide assembly (60) with a guide surface defined by a nonconcentric guide with a convex section (64) and a convex section (74) joined together end-to-end to form a generally S-shaped or approximately cubical parabolic guide surface which conforms to the natural flow shape of the product (14') for minimum interference therewith to reduce the formation of dog-ears.

Folder with gradual guide assembly and method

This invention provides an apparatus for folding sheet products, such as newspapers or the like, which includes a pair of cooperating fold rolls, a sheet supporting surface located above the fold rolls, a rotatable cage assembly carrying a tucker blade that tucks a sheet product into the nip of the fold rolls during each revolution of the cage assembly, and means mounted on the rotating cage assembly to substantially fill the space between the cage assembly and the sheet supporting surface during the time when the trailing edges of the folded product approach each other as the product is drawn through the fold rolls.

Anti-dog-ear device for a folding apparatus

This invention provides an apparatus for quarter folding sheet products such as newspapers and the like, which includes a pair of cooperating fold rolls, a sheet supporting surface above the fold rolls, a rotatable cage assembly carrying a tucker blade that tucks a sheet into the nip of the fold rolls during each revolution of the fold rolls, a pressing device for exerting a force against one group of the ends of the product being folded and cam device operating the pressing device in timed relationship with the tucking of a sheet product into the fold rolls.
