Abstract: A vertical pressure sealing assembly is disclosed for sealing four edges of a business form. The assembly defines a business form path in a single vertical plane. The assembly includes two sealing modules each having a frame to support upper and lower sealing wheels. The sealing wheels are aligned with the outer edges of the business form. Each sealing module includes a first and second pair of upper/lower sealing wheels on each side of the module frame. The first frame is positioned vertically above and offset from the second sealing module. The second sealing module is orthogonal to the first module. A form chute between the two sealing modules is positioned immediately below the first sealing module and adjacent the second sealing module. Conveyor belts and drive wheels are used to move the business form through the vertical pressure sealing assembly.

Abstract: Method and apparatus for activating longitudinal and transverse pressure sensitive adhesive strips in marginal edge portions of paper business forms are disclosed in the form of one or more roll sets which are formed to activate both the longitudinal and transverse strips while the form travels in a single orientation in a single direction that is parallel to the grain direction of the paper.

Abstract: Pressure sealing of business forms is effected utilizing first and second sets of (preferably narrow-width) rollers forming first and second nips which provide a sealing force to business forms passing between them. The first set of rollers are rotatable about first and second axes, typically horizontal, while the second set of rollers are rotatable about third and fourth axes. The third and fourth axes are substantially perpendicular to the first and second axes, and may be horizontal or vertical. The first set is typically provided above the second set, and a conveyor may be provided for conveying forms which drop from the first set into operative association with the second set.

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.
