Improvements in Machinery for Slitting or Cutting and Winding
Paper or similar materials.
I JAMES TAYLOR of 123 Harbut Road, Plough Road, Battersea, in the County
of Surrey, Engineer do hereby declare the nature of this invention and in what
manner the same is to be performed, to be particularly described and ascertained
in and by the following statement :-
By my invention reels of paper or similar material of any width can be slit or
cut into any number of narrower widths, with clean cut edges and wound into hard
recls suitable for subsequent manipulation upon printing machines, bag making
machines or for other purposes, and, when required, a damping apparatus can be
attached to and worked along with the machine, but is not claimed as my invention.
To enable my invention to be properly understood I will proceed to fully describe
the same with the aid of accompanying drawing.
Figure 1 represents side elevation of machine.
Figure 2 represents plan of machine.
A represents the reel of paper to be slit into a number of widths and re-wound,
carried on suitable bearings and supplied with suitable friction arrangements.
C. is the arrangement for producing the necessary tension upon the web of paper
and flattening it out preparatory to passing through the first set of slitters E. F.,
the paper passes over one roller B. and then is carried under a cross-bar or
roller C. so arranged that it can be raised or lowered according to the amount of
tension required for the paper, by means of screws G. G. or other suitable
mechanism. The paper is then passed over another roller D. and passes to the
slitters E. F. Slitters E. F. are mainly intended to slit the edges of the paper, or,
if necessary, could be employed to slit it also into widths. The circulars knives
are carried upon two shafts H. I. extending across the machine and carried on
suitable bearings. The bearings of the first ripper shaft I are fixed and the spindle
is driven by a driving pulley with a strap or other suitable mechanism; the
bearings of the second ripper shaft H. are carried in levers J. so arranged that, by
actuating a lever K. suitably placed, the knives can be withdrawn from contact and
the paper passed through uncut, and again the knives can be immediately placed
into the cutting position when desired, and at the same time the driving wheels L.
which drive the ripper shafts are brought into gear.
After passing through slitters E. F. the web of paper is carried under roller M. to
the reeling spindle N. which rests upon the winding drum O. and is driven by contact
with the same, the web of paper being thereby reeled upon it. P. represents
the second set of slitters knives which are placed upon a spindle Q extending
across the machine and resting at each end in bearings carried upon levers R.
which levers are so arranged that, by actuating a lever S. suitably placed, the
slitting knives P can be pressed against the reeling spindle N dividing the
web of paper into as many webs as there are slitters knives P upon the
spindle Q and the web is wound up on the spindle N into a number
of hard close reels. When it is desired to cease cutting the web of paper
the slitting knives P. are withdrawn immediately by again actuating the lever S.
The webs of paper being wound upon suitable bobbins or tubes placed continuously
upon the winding spindle N all the cut reels can be removed with facility when
complete or the same result may be achieved by means of an expanding spindle or
other suitable contrivance. The centre of lever R is preferably the same
centre as drum O.

page_text: Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is
(1) The combination of parts forming the machine for the purposes stated con-
structed and operating substantially as hereinbefore described.
(2) The method of producing suitable and variable tension upon the web
previous to passing through the first slitters.
(3) The employment of two different sets of slitters upon the same machine, the
first set being mainly for trimming the edges or for wide webs and the second set
being for narrow webs specially.
(4) The arrangement of slitting knives upon a spindle carried upon levers in
such a manner that, by suitable mechanism the knives can immediately be put to
work or withdrawn from work at the desire of the operator. In the case of the
second set of knives the rocking centre of the levers carrying the slitter shaft is
preferably in the same centre as the centre of the winding drumm although this is
not necessarily essential for the working of the machine.
