Abstract
An apparatus for advancing a sheet of material comprises a rotary member having a longitudinal axis about which it is rotated and having projecting helical propelling ridges. Equipment is provided for biasing the sheet of material to be transported towards the rotary member by drawing air through apertures at the projecting ridges. The rotary member advances the sheet of material essentially in parallel to the longitudinal axis.
