A pressure sealer machine is provided for the production of pressure sealed documents, and more specifically nested documents, that uses a number of roller cassettes disposed in side-by-side relation, in parallel to at least one drive roller, for handling forms with inserts. In the preferred embodiment, each cassette is a dual roller cassette to include infeed and ouffeed rollers. The cassettes are sized relative to the wheels so that there is a lateral gap between adjacent seal wheels, so that the cassettes produce a seal pattern composed of a series of seal strips having a uniform gap therebetween. Each cassette is spring loaded at its top side and pressure is uniformly applied to the system using a pressure plate to compress all cassette springs simultaneously.
