Abstract
An improved delivery section of a folder of a printing press in which the bucket assemblies and side guides are adjustable to accommodate varying widths of signatures.
Claims28
A bucket for a folder of a printing press, said bucket comprising:
- a hub having a first portion and a second portion releasably secured to each other, said portions when secured together defining a mounting aperture adapted so that a shaft is positionable in said aperture and so that said hub is rotatable with said shaft, said hub having an axis of rotation, said hub having a first face and a second face, a boss extending axially outwardly from said first face, a recess defined by said second face and tapering radially inwardly and axially inwardly toward said aperture, and said hub being non-symmetrical in any plane perpendicular to said axis of rotation;
- and
- a plurality of blades extending radially outwardly from said hub.
A bucket assembly for a folder of a printing press comprising:
- first and second buckets releasably mountable to and selectively positionable along a common shaft, each bucket having a rotation axis, each bucket having an individual width defined by the distance between the farthest point of said respective bucket on one side of said rotation axis to the farthest point of said bucket on the other side of said rotation axis, said buckets positionable on the shaft relative to each other such that the total width of the two adjacent buckets along the shaft is less than the sum of the individual widths of said buckets.
A bucket assembly for a folder of a printing press, said assembly comprising;
- a first bucket adapted to be releasably mounted to a rotating shaft, said first bucket having an axis of rotation and having an outer plane that is defined by a plane that is perpendicular to said axis of rotation and containing the outer most portion of said first bucket;
- and
- a second bucket adapted to be releasably mounted to the rotating shaft, and when mounted on the rotating shaft, the second bucket being oriented with respect to said first bucket in that a portion of said second bucket is positionable inwardly of said outer plane in a direction toward the remainder of said first bucket.
