ABSTRACT:
An auxiliary paper feeding apparatus is provided for feeding a continuous web of fan-fold paper from one or more serially-arranged stacks of paper into a printer. A plurality of elongate, slender turn bars are non-rotatably mounted to the frame for causing a web of paper from a source to change direction as required to feed the web of paper from the outside paper source through the access opening and into the paper storage and feeding region of the printer and into the paper feed mechanism. Each turn bar is hollow and has a number of holes through the side wall. An air pump supplies pressurized air to each of the turn bars so that the flow of air out through the holes forms an air cushion over which the web of paper passes, thereby reducing frictional drag on the paper web and enabling the printer paper drive mechanism to be the sole motive power for advancing the paper web. A paper edge guide is provided which also employs an air cushion to reduce paper friction. An associated conveyor is provided for serially conveying stacks of fan-fold paper to a pick-up position from which paper is routed to the turn bars on the frame. A paper splicer, having a vacuum-operated splicing tape hold down is provided for splicing adjacent end sheets of the stacks of paper together to form the web.
