GNI is the name to reckon with, in the world of sheet cutting.

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.
