PROVISIONAL SPECIFICATION.
Improvements in Machinery or Apparatus for Cutting and Winding
Webs of Paper.
I, THOMAS TEMPLETON MACKIE LUMSDEN of the firm of James Milne & Son,
Abbeyhill, Edinburgh, in the County of Midlothian, Engineer, do hereby declare
the nature of this invention to be as follows:-
This invention relates to improvements in machinery or apparatus for cutting
webs or rolls of paper into widths suitable for newspaper and other purposes and
for winding or reeling into a roll the webs so cut. The improved apparatus
consists of a bed or framing whereon there is supported a measuring roll over which
the web of paper to be cut is conducted from a reel whereon it is brought to the
machine the said reel being supported in adjustable bearings below the measuring
roll. From the measuring roll the paper passes under and over a guide roller and
over a drum to a reel mounted on a rotating shaft the said recl consisting of two or
more bobbins whereon the cut paper is wound. In conjunction with the measuring
roll there is provided a parallel shaft or spindle carrying circular knives by which
the deckle edges of the paper are cut off and in conjunction with the reel shaft
another parallel shaft is also provided the said shaft carrying circular knives the
number corresponding to the number of strips into which the web or roll of paper
is to be severed. The knife spindle has one or more longitudinal grooves or slots
into which gibs or keys are driven and the circular knife or knives each of which
is carried in a clamp or holder is secured to the spindle by a pinching screw which
grips upon the gib or key and by slackening which the position of the knife upon
the spindle can be altered quickly and with facility. The bobbin or reel spindle
bears at each end on an inclined cradle or bracket arm the lower extremity of
which is centred on a shaft extending from one side frame of the machine to the
other. The spindle of the reel travels up the faces of the cradle as the reel of
cut paper becomes wider in diameter and the cradle arms are also connected by
links to cranks keyed upon a horizontal shaft on one end of which a
is situated and geared with a worm screw by turning which the cradle can be
raised and lowered.

Improvements in Machinery or Apparatus for Cutting and Winding
Webs of Paper.
I, THOMAS TEMPLETON MACKIE LUMSDEN of the firm of James Milne & Son,
Abbeyhill, Edinburgh in the County of Midlothian, 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:-
This invention relates to improvements in machinery or apparatus for cutting
webs or rolls of paper into widths suitable for newspaper and other purposes and
for winding or reeling into a roll the webs so cut. The improved apparatus, which
is illustrated in side elevation by Figure I and in plan by Figure 2 of the accom-
panying drawings, consists of a bed or framing A whereon there is supported a
measuring roll B over which the web C of paper to be cut is conducted from a
reel D whereon it is brought to the machine the said reel being supported in

page_text: adjustable bearings E on the framing below the measuring roll and braked in the
usual manner. From the measuring roll B the web of paper passes under guide
roliers G and over a drum H to a reel mounted on a rotating shaft J the said reel
consisting of two or more bobbins or centres whereon the paper to be cut is wound.
In conjunction with the measuring roll B there are provided two parallel shafts or
spindles K geared together and driven by a band from the driving shaft Z'.
These spindles carry circular knives L by which the deckle edges of the paper are
cut off. In conjunction with the reel shaft J another parallel shaft M is also
provided, the said shaft being carried in adjustable bearings and driven from the
end of one of the spindles K by a belt or band N or otherwise. The shaft. M
carries a circular knife or knives O, the number corresponding to the number of
strips into which the web or roll C of paper is to be severed. In it there is or are
formed one or more longitudinal grooves or slots into which gibs or keys are driven
and the circular knife or knives O, each of which is carried in a clamp or holder P
is or are secured to the spindle by a pinching screw which grips upon the gib or
key and by slackening which the position of the knife or knives upon the spindle
can be altered quickly and with facility.
The arrangement of the shaft M relatiely with the reel spindle J is such that
there is always practically a turn of unslit paper wound on the reel unoperated
upon by knives O and any tendency of the slit webs to move endwise is thereby
obviated.
The bobbin or reel spindle J which is rotated frictionally from the guide roll or
drum bears at each end on a curved cradle or bracket arms the lower
extremity of which is centred on studs R in the frame A of the machine. The
spindle travels up the faces of the cradle Q as the reel of cut paper becomes
larger in diameter being restrained or braked in its movement by the levers S
centred on the bearings T. When the machine starts to wind friction pressure is
put on the reel spindles to hold it against the drum H by cords a and weights b.
The cradle arms are connected by adjustable links V to cranks W keyed upon a
horizontal shaft X on one end of which a worm wheel Y is situated and geared
with a worm screw Z by turning which the cradle Q can also be raised and
lowered.
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. In a machine of the class set forth the combination of the measuring roll B
and the shafts or spindles K, K, M, each carrying knives, those on the spindles K
trimming the deckle edges of the paper web and those on the spindle M cutting
the web into the desired widths substantially as set forth with reference to the
drawings annexed.
2. In a machine of the class set forth the combination of the apparatus for
cutting a web of paper into desired widths with the mechanism for simultaneously
winding or reeling the paper before it is cut, the complete breadth of the web of
paper keeping the cut widths from spreading laterally, substantially as described
with reference to the accompanying drawings.
