Abstract: An apparatus and method for verifying the number of articles, preferably intended to be credit, debit, or similar cards, in a carrier is described. Though different embodiments are possible, the preferred embodiment comprises a caliper apparatus and microcontroller electrically linked to an inserter machine controller. The controller of the inserting machine is also electrically linked with an indicia reader mounted at the entrance to the inserter machine. The indicia read is found on the carrier and represents a machine readable representation of the number of articles that should be found in the carrier.

Abstract: A collector apparatus and method are provided for collecting sheet articles and advancing collected sheet articles therefrom. The collector apparatus includes a collector plate having a surface for receiving one or more sheet articles thereon to collect the sheet articles. At least one stop bracket is movable through an opening defined through the collector plate to provide a stop for collected sheet articles and to allow collected sheet articles to be further advanced from their collection position. At least one upper idler drop roller is spacedly positioned above and movable toward the collector plate surface.

Abstract: An envelope sealer includes a first horizontal plate for receiving an envelope, a vacuum manifold for drawing open the envelope's downward-facing flap as it departs from the first horizontal surface, and a plow for catching the flap and directing it such that the flap travels below a second horizontal plate while the body of the envelope travels above the second horizontal plate. A fiber-optic sensor system is provided for detecting the non-presence of a flap during the travel of the envelope over the second horizontal plate and for actuating a downstream diverter in response thereto. An unseal unseal ramp is provided for lifting the flap over the plow if it is determined that the envelope should not be sealed. During the flap 's travel below the second horizontal plate, it passes and engages a wetted brush, whereby water is applied to the flap's adhesive surface.
