Apparatus and process for producing different hole patterns in sheet-shaped print materials

An apparatus for producing different hole patterns in a sheet-shaped print material, comprising:

• a tool roller having punches and a camshaft disposed within said tool roller, said camshaft having cams engaging said punches wherein movement of said camshaft disposed within said tool roller permits lowering said punches relative to an outer surface of said tool roller by a relative rotation of said camshaft with respect to said tool roller;
• a die roller opposing said tool roller in operative engagement therewith, said die roller having dies corresponding with said punches;
• and
• a through-teed path passing between said tool roller and said die roller for sheet-shaped print material.

An apparatus for producing different hole patterns in a sheet-shaped print material, comprising:

• a tool roller having punches and a camshaft disposed within said tool roller, said camshaft having cams engaging said punches wherein movement of said camshaft disposed within said tool roller permits lowering said punches relative to an outer surface of said tool roller and said camshaft has a center portion having no said cams, and a first outer portion and a second outer portion having said cams;
• said punches including a first outer set of punches, a second outer set of punches, and a center set of punches therebetween and wherein rotation of said cams positions said first outer set of punches and said second outer set of punches resulting in an uninterrupted series of raised punches extending from said center portion to an innermost punch in each of said first outer set of punches and said second outer set of punches;
• a die roller opposing said tool roller in operative engagement therewith, said die roller having dies corresponding with said punches;
• and
• a through-feed path passing between said tool roller and said die roller for sheet-shaped print material.
