Vacuum hold down folder/gluers and process

A modular vacuum hold down device for a folding mechanism for pre-scored paper-board articles, including a first vacuum hold down device comprising:

• a substantially enclosed, free-standing, rectangular-shaped conveyor housing having legs such that said housing may be relocated without regard as to any other machinery, a vacuum inlet, side plates, a conveyor table having vacuum holes along its length, and defining a vacuum chamber therein;
• at least one conveyor belt in between said side plates and spanning said conveyor table such that said at least one conveyor belt cannot flex;
• a drive mechanism associated with said at least one conveyor belt for driving said at least one conveyor belt;
• a vacuum source comprising a blower driven by a motor, said vacuum source in fluid communication with said vacuum inlet, whereby when said vacuum source is activated, a vacuum is created in said vacuum chamber and in an area of said conveyor table having said vacuum holes, thereby causing said pre-scored paper-board articles to adhere to said at least one conveyor belt and against said conveyor table;
• said blower motor and said drive mechanism mounted to one of a left side and a right side of an outside of said conveyor housing to form one of a left-handed version and a right-handed version, respectively;
• and
• folding elements spaced above said conveyor housing for folding and forming a flat pre-scored paper-board article fed from an article feeder, said folding elements independently movable with respect to said modular vacuum hold down device to form said article into a container.
