GNI Heavy-Duty, High-speed,  Online and Offline Simplex and Duplex Sheet Cutters are and ideal choice for paper mills throughout the world today. To User-mills GNI means their full money-worth, while for the competitors GNI is the name to reckon with, in the world of sheet cutting.

To achieve perfectly square cut, maximum sheet production with minimum most-tolerances on cut sheets, GNI offer SHEET CUTTERS to handle 40-1200 GSM range of paper and board with suitable number of unwind stands. The unwind stands are  built, keeping easy access and convenience of operator in mind. Mills can use up to 1 to16 reels at a time, depending on of course gram mage of paper to be handled.

An extra conveyor replaces conventional over-lapping method and takes good care of sheet collection process. The salient feature of GNI SHEET CUTTERS is the provision of Micro-screw adjustment for effortless and silk-smooth sliding of entire cutting bed head for most efficient cross cutting operations, to ensure absolutely square-cut end product.

A well designed and precision engineered rubber grooved ( Manual / Pneumatic operated ) pressure roll provides  perfect gripping of the moving web, for its smooth onward movement to the cutting head. Also, a perfectly engineered and critically located wooden grip roll with wooden strips in segment formation duly mounted on a steel roll ensures perfect anti-creasing action for a smooth entry into the cutting head.

GNI ON-LINE sheet cutters are eminently suited, particularly for papers of  100 GSM and above. GNI recommends OFF-LINE sheet cutters for handling light grades of web below 100 GSM.
