Universal half folder apparatus

摘要

A continuous sheet folder apparatus is disclosed that can fold any size paper in half with nested inserts inside the paper. The apparatus can also function in an intermittent mode. The half folding apparatus is accomplished by a set of lifting fingers and stationary fingers which interact to curl the sheet leading edge upwards and over until it registers with the trailing edge, passing beneath it. The sheet is then creased in a presser unit. The lifting fingers are spring mounted and biased toward the oncoming sheet.
