This GUK Grieser & Kunz is a flexo-folder gluer — a machine used in the corrugated packaging industry to print, fold, and glue flat corrugated blanks into finished boxes in a single continuous pass. These machines are also commonly referred to as FFGs or box-making machines. GUK, operating under the Grieser & Kunzmann name, is a well-established German manufacturer with a long history of producing converting machinery for the corrugated board and carton industry.
This machine dates from 1987 and is offered in used condition from a seller based in Germany. The infeed section is equipped with a Gremser flat pile feeder fitted with a counter, providing controlled and measured blank feeding into the line. The first folding unit has six pockets and accepts blanks up to 72 cm in infeed width, giving the machine a substantial working range for a variety of box formats.
Downstream of the folding unit sits a slitter shaft, used to make longitudinal cuts or score lines on the board as it passes through. The machine includes two cross-break swords — one positioned in the first folding unit and one further along the line — which apply transverse creases to the blanks to facilitate clean folding. A folding pocket in the lying position is also present, contributing to the machine's ability to handle a range of fold configurations.
Additional equipment includes a Shed display SA 72 and a window fold pocket, the latter enabling the production of boxes with window cut-out panels. The machine represents a well-specified example of older German corrugated converting equipment, combining feeding, slitting, cross-breaking, folding, and windowing functions within one integrated line.
