Abstract: 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.

Abstract: A method and apparatus for high speed merging of sheet material onto a transport from the side is disclosed. The apparatus includes a pocket formed from a series of bottom guides, a series of top guides, a side restrain, a front and rear backstop, all mounted to a framework and being mounted slightly above a transport via a provision. A source feeds insert material into the pocket at which time the insert material is held therein until advancing transport picks engage the insert as the picks pass through slots in the pocket and propel the insert out of the pocket and on to the transport or an existing sheet already on the transport. Paper control devices are positioned within the pocket to dampen bounce and help keep the insert contained in the pocket.
