Form burster
First Claim
1. Apparatus adapted to burst form sets from continuous business form assemblies along burst lines and adapted to be adjustable to varying form set depths, the apparatus comprising:
- a frame;
an intermittently operatively cooperating pair of entry rollers on the frame, a first of the entry rollers being rotatable about a first axis of rotation and revolvable about a first axis of revolution; and
an intermittently operatively cooperating pair of exit rollers on the frame, a first of the exit rollers being rotatable about a second axis of rotation and revolvable about a second axis of revolution;
the revolutions of the entry and exit rollers being timed relative to each other and adjustably timed relative to the speed of the continuous business form assemblies such that both pairs of rollers operatively cooperate substantially simultaneously with each other, such that both pairs of rollers operatively cooperate while burst lines of the assemblies are between the entry rollers and the exit rollers, and such that the periods of intermittency of the roller cooperation coordinates with the depths of the form sets of the assemblies.

Abstract
Apparatus to burst form sets from continuous business form assemblies along burst lines, and adjustable to varying form set depths. An intermittently operatively cooperating pair of entry rollers and an intermittently operatively cooperating pair of exit rollers are on a frame. A first of the entry rollers is rotatable about a first axis of rotation and revolvable about a first axis of revolution. A first of the exit rollers is rotatable about a second axis of rotation and revolvable about a second axis of revolution. The revolutions of the entry and exit rollers are timed relative to each other and adjustably timed relative to the speed of the continuous business form assemblies. Both pairs of rollers operatively cooperate substantially simultaneously with each other. Both pairs of rollers operatively cooperate while burst lines of the assemblies are between the entry rollers and the exit rollers. The periods of intermittency of the roller cooperation coordinates with the depths of the form sets of the assemblies.

23. Apparatus adapted to burst form sets from continuous business form assemblies along burst lines, the apparatus comprising:
-
a frame; and nip means on the frame for intermittently nipping and stressing the assemblies across the burst lines to burst the form sets from the assemblies along the burst lines, the nip means including nipping elements having movable axes, and movement means for moving the axes and thereby the nipping elements toward and away from nipping positions about multiple axes of revolution; in which each nipping element having a movable axis is rotatable about said movable axis, has an axis of revolution, and is revolvable about said axis of revolution. - View Dependent Claims (25, 26, 27, 28)

24. Apparatus adapted to burst form sets from continuous business form assemblies along burst lines, the apparatus comprising:
-
a frame; and nip means on the frame for intermittently nipping and stressing the assemblies across the burst lines to burst the form sets from the assemblies along the burst lines, the nip means including nipping elements having movable axes, and movement means for moving the axes and thereby the nipping elements toward and away from nipping positions about multiple axes of revolution; in which at least one of said nipping elements having a movable axis is a roller; and in which the roller has a roller surface, the movable axis of the roller is an axis of rotation for the roller surface, the roller has an axis of revolution between the roller surface and the axis of rotation, and the roller is revolvable about the axis of revolution.
