Abstract: A system for forming and sealing envelopes stuffs each envelope with an insert. Envelope blanks are received and fed to an envelope former. The envelope former partially forms the envelope blanks with a sealed longitudinal end and an open longitudinal end. Insert blanks are fed and are formed into inserts. The inserts are moved along longitudinal axes and into the open longitudinal ends of the partially formed envelope blanks parallel to the envelope longitudinal axes.

Abstract: Apparatus and method for handling business forms that are zig-zag folded including a printed forms transport and a printed stack transport, the printed forms transport including a caster-equipped undercarriage and a generally elongated forms-receiving box pivotally mounted on the undercarriage, the box having a pair of sides, an open end for receiving the forms and a closed end, an open top and a planar bottom, a tine member removably mounted on the box at the open end, a printed stack transport releasably engaged with the printed forms transport, and cylinders connecting the undercarriage with the box for pivoting the box through a vertical arc to convert the string of forms to a stack of business forms and to deposit the stack on the printed stack transport, the printed stack transport having a platform equipped with elongated slots aligned with the tine member when the printed forms transport and the printed stack transport are engaged.

Abstract: A burster including spaced infeed and outfeed pairs of rollers in fixed spacial relationship with respect to each other which are driven by a system including a variable, limited lost motion connection to the infeed rollers. The connection includes a long-lived tooth and stop assembly wherein impacting surfaces of the tooth and the stop members are configured to minimize shear stresses occurring in the tangential direction in favor of readily absorbed radial stresses to thereby provide a long-lived apparatus.
