Abstract
A system for folding sheet material, including a fold blade, a fold roller, and a driver for moving at least one of the fold blade and the fold roller along a first path into operative communication with one another. The operative communication causes displacement of the fold roller along a longitudinal axis of the fold blade.
Claims15
A method for folding a sheet of material, comprising the steps of:
- feeding a sheet material into an area between a fold roller and a fold blade;
- and
- moving the fold roller and the fold blade relative to one another to form a fold in the sheet using the fold blade,
- wherein an operative communication between the fold roller and the fold blade displaces the fold roller along a longitudinal axis of the fold blade, and the operative communication pivots at least one fold arm having the fold roller rotatably attached to a first end, the arm being pivotably attached to a housing of a fold apparatus, such that the fold roller rotates along the longitudinal axis of the fold blade.

A system for folding sheet material, comprising:
- a fold blade;
- at least one fold roller;
- drive means for moving at least one of the fold blade and each of the at least one fold rollers along a first path into operable communication with one another;
- and
- at least one arm, wherein each arm has one of the at least one fold rollers rotatably attached to a first end and the arm is pivotably attached to a housing of the fold apparatus,
- wherein the operative communication causes displacement of each of the at least one fold rollers along a longitudinal axis of the fold blade, and
- wherein the operative communication pivots each of the at least one arms such that each of the at least one fold rollers rotates along the longitudinal axis of the fold blade.

- at least one arm, wherein each arm has one of the at least one fold rollers rotatably attached to a first end and the arm is pivotably attached to a housing of the fold apparatus;
- and
- a plurality of springs, one of the plurality of springs attached to a second end of each of the at least one arms, wherein the one spring forces the fold roller of the at least one arm against the fold blade as the fold roller rotates along the longitudinal axis of the fold blade.
