Roll Feed Blousing Bail

Improved tracking and incrementing of a web from a supply roll result when the reactive force of a blousing bail and roll brake are varied directly with the diameter and weight of the roll.

The figure shows one end of the mechanism for controlling the blousing bail or dancer bar and is duplicated at the opposite end. Web 1 is withdrawn from supply roll 2 over a resiliently biased bail 3 by the nip of an incrementally rotating feed roll 4 and pressure roll 5. As the web is withdrawn over the bail from the roll, bail arm 6 rotates downwardly about pivot 7 against the urging of tension spring 8 connected between bail arm end 9 and treadle 10. A second tension spring 11, secured to frame 12, urges the treadle counterclockwise about pivot 13 to pull the treadle into engagement with the surface of roll 2. As the roll decreases in diameter and weight, both tension springs 8 and 11 decrease their force on bail 3 and reduce the braking action of the treadle on the roll surface.
