Abstract

Improved method and apparatus for heat sealing strips of encodable material to documents, a continuous supply of the encodable material being fed, by way of a discrete loop feed assembly, to an alignment station where defined lengths thereof are aligned along the edge of documents transported thereto. A heater-drum assembly effects the heat-sealing of the aligned combination which is then transported, by way of a stacker-deflector assembly, to an output station. The transport of the documents and encodable material are assisted by a continuously running friction belt drive assembly with the severing of the encodable material into strips equal to the length of each document effected in response to photosensor actuated controls responding to the transport location of the documents and material.
