Abstract

An apparatus for transferring sheet materials comprises a plurality of externally threaded rods having threads spaced at equal pitches and grooves therebetween. The threaded rods extend parallel to each other and are mounted in a one-sided box-shaped housing for rotation about their axes. The threaded rods are drivable for synchronous rotation in the same lead direction to transfer the sheet materials inserted edgewise in the grooves of the threaded rods in the lead direction in synchronism with rotation of the threaded rods.
