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.
Apparatus for affixing a plurality of loose pages into bound form comprising binding means for receiving said pages in cooperation with a glue member thereon, a chassis having an upper carriage means movable between a loading position loosely accommodating said binding means with said pages therein and a binding position to retain said binding means with said pages therein, heating assembly means mounted on said chassis and substantially underlying said carriage means said binding position for providing heat to said binding means during a binding cycle to melt said glue member, timing means for controlling the application of heat from said heating assembly to said binding means and indicating means for signaling the conclusion of said binding cycle, wherein said heating assembly means comprises printed circuit means for providing said heat to said binding means and conductive means for conveying said heat from said printed circuit means to said binding means.
Apparatus for affixing a plurality of loose pages into bound form comprising binding means for receiving said pages in cooperation with a glue member thereon, a chassis having an upper carriage means movable between a loading position loosely accommodating said binding means with said pages therein and a binding position to retain said binding means with said pages therein, heating assembly means mounted on said chassis and substantially underlying said carriage means in said binding position for providing heat to said binding means during a binding cycle to melt said glue member, timing means for controlling the application of heat from said heating assembly to said binding means and indicating means for signaling the conclusion of said binding cycle, wherein said binding means includes a front cover portion, a rear cover portion and a spine portion between said cover portions, said glue member being affixed to said spine portion, and page retaining means disposed on each of said cover portions for holding said pages in substantial alignment with each other when said front and rear cover portions are brought towards each other at said loading and said binding positions.
