Abstract: An apparatus for automatically applying a pressure-sensitive tab to the edge of a mailer which includes a feed spool of pressure-sensitive tape. The pressure-sensitive tape is fed through a tape slot of a tape guide block from where it is wound upon a driven windup spool. A pneumatically driven (or, if desired, solenoid driven) punch and die arrangement is positioned so that upon actuation, the die cuts a circular segment of the tape and wiper arms apply the circular cut tape segment to the edges of a mailer. This can be done while the edges of the mailer are stationary or moving parallel to the direction of the tape.

Abstract: Apparatus for banding a stack of envelopes includes an elevator mechanism which moves the stack in a path between a first lowermost position to a second uppermost position; first and second tensioning units for applying a tensioning force to a first banding strap positioned across the path at a first location between the first and second positions and extending in a first longitudinal direction; first and second sealing and separating units for wrapping, sealing and separating opposite ends of the first elastic banding strap about the stack of envelopes when the elevator mechanism has moved the stack of envelopes past the first location; third and fourth tensioning units for applying a tensioning force to a second elastic banding strap positioned across the path at a second location between the first and second positions and extending in a second widthwise direction substantially transverse to said first longitudinal direction; third and fourth sealing and separating units for wrapping, sealing and separating
