Abstract: A machine for binding a plurality of loose sheets into bound pamphlet form is disclosed, together with a cover suitable to receive such sheets. The machine has a stationary base to which a main chassis is fixedly mounted. A movable carriage is mounted for slidable movement with respect to the chassis by means of rollers fixed to the carriage and which slide along the inner side edges of the upper plate of the chassis. When the carriage is in the open position, its upper rear wall is separated from the fixed rear wall of the base, thereby exposing an underlying heating channel and permitting the insertion therein of a cover containing pages to be bound thereto. The chassis is then moved to a relatively closed position, whereby its rear wall approaches the corresponding rear wall of the base, retaining the cover and its contained pages therebetween. A brief heating cycle, utilizing a printed circuit board in the heating channel, then causes the pages to adhere to a pre-glued strip along the inner spine of the cover, which has become somewhat viscous during the heating cycle. The cover is then removed and following a short cooling period, the bound pamphlet is completed. In one embodiment of the cover to be used with this invention, thin flexible strips running parallel to the spine of the cover are affixed to the inner surfaces of the front and rear cover portions to provide sufficient rigidity to retain the pages in a firm binding position in the cover when the carriage is moved to its closed position and the heating cycle is initiated. Other embodiments of the cover provide for adhering different binding members to the cover member to provide binding versatility.
