ABSTRACT OF THE DISCLOSURE A machine allows the production of pressure sealed business forms either by a "steam roller" effect for two ply forms, or by using a number of dual roller cassettes spaced from each other along an axis of rotation when forms with inserts are handled. The first roller in each cassette, after sealing a portion of the leading edge of the form that it engages, will rock out of the way when engaged by the form at the insert, and then will drop back down and seal the trailing edge. The narrow width rollers of end cassettes will seal the longitudinal edges of the form. The stationary axis rollers that are common to both the "steam roller" and cassette embodiments have a dead-shaft construction, and are driven by a motor. Side frame plates mount all of the components, except the motor, within a housing, on rails, so that they can be easily moved out of the housing for changeover from one roller system to the other. The steam roller type idler rollers also have a dead-shaft construction and are suspended in the X, Y, and Z axes by leaf spring cantilevers.
