ABSTRACT:
First and second bundles of interfolded webs are formed. The uppermost web half of the first bundle is interfolded with the lowermost web half of the second bundle at a merging station. These web halves travel along parallel and inclined fold surfaces and become interfolded upon being discharged therefrom. To unfold the uppermost web half for travel along its associated fold surface a freely rotatable roller is positioned upstream of such fold surface. The roller is arranged to be contacted and frictionally driven by the uppermost web half. The roller is oriented toward the fold line of the uppermost web half so that upon driving the roller, the uppermost web half becomes unfolded. To promote unfolding of the lowermost web half of the second bundle a stationary elongate band is disposed between the lowermost web half and the remaining web halves of the second bundle. When the second bundle is discharged from a conveyor upstream of the fold surface associated with the lowermost web half, the latter gravitates to an unfolded position and is thus able to travel along such fold surface.
