In an electrophotographic printing machine, a high performance recirculating document handler is frequently employed to advance successive original documents onto the platen of the printing machine for reproduction. The document handler requires a vacuum belt for handling the original document. Preferably, the belt has a series of grooves thereacross with numerous holes at the bottom of each groove. The vacuum creates suction through the holes which travel along the grooves to hold the original document to the belt as it is transported. A belt of this type may be formed from two separate films of polyester, each about 0.005 inches thick, and die cutting slots, i.e., grooves, into one while die punching holes into the other. The two films are then laminated together by means of a heat activated coating on each inner surface. The ends are then joined together by ultrasonic welding or heat sealing to form the final belt.
