This space saving system enables production of pinless 4 and 8 pagers as well as various gate folded and flat covers. A low cost alternative to Pinless Double Former Folder, the system is available with or without the sheeting capability.

The 4P/8P System consists of a Horizontal Double Former section and a shear type cutting section. The Horizontal Double Former section takes 38" wide web and slits it into two ribbons. The ribbons go over air angle bars and are folded by steep angle formers, positioned in the horizontal plane. The ribbons can be folded individually to produce two folded streams for producing 4-pagers, or they can be folded together to produce 8-pagers. The angle bars and compensator are motorized, with controls located at the Double Former section as well as at the delivery end. Angle bars are configured for unlimited page imposition capability.

In order to save make-ready time for repeat jobs, digital position indicators are provided for angle bars and compensators. The compensators are wired to work simultaneously with angle bar movement. Air-loaded nip wheels on the pull rollers are provided. Adjustable guide rollers after the former enable the folded ribbons to go straight to the Sheeter pull roller without having to go over other lead rollers.

The folded ribbons go to a shear type rotary cutter with two around cut and deliver in a shingled stream. In Sheeter Plus 4P/8P System, the rotary cutter is replaced by Sheeter enabling production of 4s,8s as well as full size cut sheets. The system can be located in straight-line or at right angle to press.

This system produces four 4 pagers in four delivery streams and two 8 pagers in two delivery streams.

The rotary cutter unit incorporates a diverter section to divert front half of sheet into a different level of belts, enabling production of different sections.

GATE FOLD STATION enables producing single and double gatefolded 6 and 8 pagers. The station is provided with full web angle bar for web shifting and two INNOFORMER™ folding assemblies to make single or double gates in the web. The Gatefold Station is located behind the Horizontal Double Former section and delivers the folded web to the Horizontal Former for final fold. An optional spot gluer is available to hold the corner of gatelegs for ease of processing through the bindery.

GAP CUTTING OPTION

Patented vacuum cutterhead is incorporated in the rotary cutter to produce finished, trimmed to size 4,6

and 8 pagers. The vacuum cutterhead is provided with two double knife holders. Each double knife holder cuts one chip, varying in size from 1/4" to 1", that is pulled into the body of cutterhead by vacuum applied to the stationery ends of the cutterhead. The internal construction of vacuum cutterhead contains special passages for streamlined flow of trim to opposite ends of cylinder from each double knife holder.

• Straight line, right angle or U-configuration installation.
• Line Gluer for glued 8 pagers.
