ABSTRACT:
The present invention provides an automatic machine for making accordion data pockets, especially an automatic machine which is capable of bonding the inner leaf members, side cover members, and bottom member of an accordion data pocket together in one step. The machine is characterized by a fixed and a movable die seats, a top press die, two side press dies, two side boards, etc. The movable die seat has a plurality of cavities formed on its top surface, allowing index holders provided on each inner leaf member of the data pocket to insert in, and a plurality of properly and equally spaced partition plates vertically erected thereon. The fixed die seat has a plurality of properly and equally spaced positioning plates vertically erected thereon and each of the positioning plates has chamfers formed at its one vertical side and its top horizontal side. After the already molded plastic leaf members, cover members and bottom member of the data pocket are separately positioned in place, the machine is switched on to move the movable die seat and press dies to heat seal and thereby bonds these components in one step and effectively produces a complete accordion data pocket.
