ABSTRACT:
A folding machine includes a first folding roll with a series of the gripper assemblies and a series of tucker assemblies uniformly and alternately spaced to interact with a series of gripper and tucker assemblies of an adjacent second folding roll. The series of alternately spaced gripper and tucker assemblies interact to grip, carry, and release a sheet material in a manner so as to generate an interfolded stack of sheet material. The folding machine further includes a phase adjustment assembly configured adjust the location of the fold in the sheet material, to locate the fold in a proper position on the sheet relative to the leading end of the successive sheet. The phase adjustment assembly generally includes a first helical gear that moves along an axial direction, and an input device configured to cause the axial movement of the first gear so as to cause a change in phasing and a change in location of the fold in the sheet material.
