I, JAMES GOWANS SERVICE, of Glasgow, in the County of Lanark, North
Britain, Manufacturer, do hereby declare the nature of the said Invention for
"IMPROVEMENTS IN MACHINERY OR APPARATUS FOR CUTTING AND SCORING PASTE-
BOARD AND OTHER SIMILAR MATERIAL," to be as follows, that is to say :-
This Invention relates to the arrangement and construction of machinery
adapted for cutting pasteboard to any required form, and for scoring or
partially cutting through certain parts to admit of the pasteboard being readily
bent up to form, for example, a box. Under one modification: the machine
consists of a pair of open-end standards, in which are arranged the bearings
of a pair of rollers. Motion is communicated to the lower roller either by
hand or power, and this roller carries to and fro a table to which a recipro-
cating traverse is imparted. In this table are fitted the knives for cutting the
pasteboard to the required figure; these knives are made adjustable as regards
height by means of screws contained within the body of the table, so that the
knives may be adjusted either for cutting or scoring. As arranged for cutting
pasteboard for box-making, the knives cut the pasteboard to the required size,
and cut out the corner pieces, whilst the central part, which forms the top or
bottom of the box, is scored to facilitate the bending-up of the pasteboard to
form the sides and ends of the box. These knives may be arranged to cut
one or more boxes at one operation from the sheet of pasteboard. The upper

page_text: roller is arranged in bearings which are adjusted by means of a screw, so as
to regulate the pressure of the roller upon the pasteboard, and the surface of
the roller is covered with sheet lead or an amalgam of that metal, so as not
to injure the edges of the knives. When the table is run out to the end of its
traverse, a sheet of pasteboard is upon the knives, and the table is traversed
under the upper roller, the pressure of which causes the knives to cut the
pasteboard to the required figure, whilst the central part is merely scored.
When the table is traversed forward its extremity comes in contact with a
lever, which motion actuates a plate having a number of vertical pins pro-
jecting up from its face. This plate ascends sufficiently to allow of the pins
coming in contact with the pasteboard so as to release the several pieces from
the recesses formed in the table by the arrangement of the knives. As the
table traverses back again a brush, roller, or other equivalent sweeps the paste-
board into a box beneath. The several pieces for forming the boxes and lids
are subsequently separated from the corners or waste. This cutting machine
may be arranged to take on a sheet of pasteboard at each side of the rollers,
suitable provision being made for clearing the cut pasteboard and putting
on a new sheet at each traverse of the table, and thus producing double the
quantity. Or instead of arranging the knives in a traversing table they may
be fitted in one of the rollers, and the pasteboard cut as it is passed between
them. These machines are well adapted for cutting pasteboard for bookbinders
and other generally similar purposes.
