SLITTERS

317

A very simple and efficient winder has a cylinder about 9 inches in diameter
formed of sections which fit on to a centre. These segments are of various
lengths so that slitting knives in the form of thin steel discs may be introduced
between them at the required distances. The whole is fixed by screws and
lock nuts at each end.

Cutter discs cut the side shavings, but the actual splitting takes place on the
cylinder on the top of which the web is run. This machine has the advantage
that the split edges cannot run into each other, the cutting discs protruding

from the cylinder about J inch. On winders where all the splitting is done by
ordinary cutter discs it is often a matter of difficulty to prevent the cut edges of
adjacent webs interlocking. It is usual to have a flexible steel bar over which
the paper is dragged, and which is bent by set-pins by the attendant into such
shapes as to keep the cuts open. On other winders the slitting is done by means
of small steel discs attached by rocking levers suitably weighted to a cross-
bar. They are moveable sideways on the bar for adjusting to the breadth
of the web required. Being fixed between two circular plates * inch less in
diameter, they are thereby kept from being jammed in the cut by the pressure
of levers, and in contact with the web coming off the drum. An attachment
