Product Description

The Solna F780 are combination jaw folders intended for high quality folding. The F780 is best suited for semi-commercial and newspaper work.
The Solna F780 folder is designed to be combined with a Solna Distributor 300, a Solna Commercial 300 and Solna Print System 600. It has capacity for up to 8 webs in one section with a tabloid cross fold. The F780 also has provisions for an additional length fold (quarter fold), a double parallel cross fold and a Swiss postal fold across the quarter fold.

The F780 belongs to the category of fixed sized single cut-off jaw folders with conventionally positioned former. These folders are available in cut-offs 578 mm (22 3/4 "), size B, and 546 mm, size K.
The basic folder will give a single cross fold after the former length fold to produce a broadsheet or tabloid product. With optional double parallel cylinder mechanism, the signature may be given a second cross fold. The Quarter Fold mechanism, which is standard on the F780, can be used to make a second length fold.
All products exit on the same delivery belt which lies at right angles to the press line.

The drawing below shows a top view of an F780 folder. The printing units are normally found on the left side of the former, the side unit. (With optional arrangements, printing units may also be found on the right side.)
The back side of the folder is also named the drive side of the press as the main drive shaft or the separate printing unit driving motors are situated on this side. The delivery side is the front side of the folder towards the Press Console.
