Abstract: This apparatus provides a continuous form with a series of precut, longitudinally spaced record cards adhered thereto so as to be movable by conventional forms tractors through a high-speed printer. The cards have detachable marginal stub portions that are glued to the form by a heat-settable glue. After glue is applied to the form, the cards are fed onto the form. The card/form assemblage is then advanced through an elongated nip between two sets of opposing endless belts, at least one of the belts of each set being heated, to subject the assemblage to heat and pressure for a period of time proportional to the length of the nip and speed of the belts to set and dry the glue so as reliably to seal the cards to the form. Application of the glue to the form and of the cards to the glue is performed while the form and cards are in continuous motion, providing a high throughput.
