Improvements in the Manufacture of Paper Bags and other such
articles.
I, WILLIAM HENRY HOLLAND of Stamford Villa New Humberstone in the
County of Leicester Agent do hereby declare the nature of this invention to be as
follows:-
This invention relates to the manufacture of paper bags, and other such articles
that require to be folded and the edges thereof sticking down to form an envelope,
cup, or bag useful for a variety of purposes, such as for holding flour, biscuits,
sweets, or papers, letters and the like, made of paper, parchment, linen, linen lined,
or other suitable inaterial.
I carry out my invention by the aid of a cut pattern and shaper plate" herein-
after described, and ordinary patterns of such articles can also be made on the
shaper plate" if necessary, but articles made from my pattern are put together
with greater facility than the ordinary ones, which as regards flour or biscuit
bags consist of a blank which has a piece cut out at the left hand top corner
(taking the way the bag has to be folded) the width of one side of the article and
leaving a lip along the other side, this and the projecting edge of the side at right
angles to the said lip are pasted, the part forming the side of the bag is then folded
over, and the projecting edges are turned over and rubbed down and the bag is
completed. I avoid the aforesaid first operation of folding or first doubling over.
I take a rectangular blank cut out by any suitable knife, or the like to the size of
bag required, or cut from a long strip of paper, linen or the like of the width
required rectangular blanks leaving upon one of the longer sides a flap with the
edges rounded off cut out of the centre of the lower edge of the preceding blank.
I then arrange two dozen or more of the said blanks all regularly in order with the
same width of flap and one side left exposed, then paste over the said edges, they
are then transferred in a body to the folding appliance constructed in the following
or equivalent manner. Upon a base board, bench, counter, stand or other con-
venient flat surface I arrange horizontally a rim of iron, wood, or other material,
and fit up to this a shaper plate" in the form of a sheet of thin metal and secure
it firmly at its lower end by screws, screw nuts, or strip forming a clip made fast by
thumb screw or other convenient means, this plate is of the size of the bag desired,
and conforms with the width of the flap to form the bottom of the bag and being
made of thin steel by preference acts as a spring, the blank is then placed under it
so that the turning over edges are perfectly straight for folding, the "shaper" is
then pressed down on to the base by bringing over the side quarters and securing
one over the other, the flap being turned up by contact with the rim is then pasted
down, the pressure is then taken off when by reason of its flexibility the "shaper
plate rises, so that the bag is easily removed therefrom, and another takes its
place. For sweet bags "the "shaper plate" is conical or triangular, it may be
of any pattern to produce the right shape of bag or envelope. The " shaper
plates" may be rigid and have india rubber or metal spring or springs pressing on
their under sides if necessary.

Improvements in the Manufacture of Paper Bags and other such
articles.
1, WILLIAM HENRY. HOLLAND, of Stamford. Villa, New Humberstone in the
County of Leicester Agent 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 the manufacture of paper bags, and other such articles
that require to be folded and the edges thereof sticking down to form an envelope,
cup, or bag useful for a variety of purposes, such as for holding four, biscuits,
sweets, or papers, letters, and the like, made of paper, parchment, linen, linen lined
paper, or other suitable material..
That my invention may be well understood. I have annexed hereunto a sheet of
drawings in which
Figure 1. is an elevation of a blank to form a bag or envelope in accordance
with my invention.
Figure 2. is an upper view of the knife employed for cutting out the blanks
aforesaid.
Figure 3 is a view looking from the top of the folding apparatus hereinafter
described and

66
Figure 4. is a modification of same.
This invention is effected by the aid of a cut pattern such as A, and folded by a
shaper plate such as B, and ordinary patterns of the herein mentioned articles
can also be made on the shaper plate" if necessary but articles made. from the
pattern Aas shown in Figure 1, or its equivalent are put together with greater
facility than ordinary ones, which as regards "flour or biscuit bags" are made
from a blank having a piece cut out at the left hand top corner (taking the way the
bag has to be folded,) the width of one side of the article and leaving a lip along the
other side, this and the projecting edge of the side at right angles to the said lip.
are pasted, the part forming the side of the bag is then folded over, and-the pro-
jecting edges are turned over and rubbed down and the bag is completed. By my.
invention. I avoid the aforesaid first operation of folding, or first doubling over. by
taking the rectangular blank A or its equivalent, previously cut out by the knife.C
Figure 2" fitted by the brackets c¹ to the press of any ordinary kind worked either
by hand wheel from top, or power as the case may be a quantity at a time
- according to the capacity or height of the head or plunger being cut upon the
downward movement of the head or plunger. The blanks are produced to any size.
required whether in width or length and leaving upon one of the. longer sides a
flap a with the edges. rounded off cut out of the centre of the lower edge of the
preceding blank.
I then arrange two dozen-or more of the said blanks all regularly
iu order with the same width of flap and one side left exposed of a similar width
then paste over the protruding edges, they are then transferred in a body, to the
folding appliance constructed in the following or equivalent manner.
Upon a-base
board, bench, counter, stand or other convenient flat surface I arrange horizontally.
a rim of iron, wood, or other material and fit up to this the "shaper plate" Bin-
the form of a sheet of thin. metal which is secured firmly at its lower end by the
screws; screw nuts, or:strip "not shown" forming a clip.or. clamp. made fast by.
thumb screws or other convenient means, this plate is of the size of the body of the
bag to be made, and conforms with the width of the flap a, to form the bottom of
the bag, the "shaper plate" is by preference made of thin steel is flexible and acts
as a spring. The operation of folding is as follows the blank A is placed under the
shaper plate so that the turning over edges are perfectly straight for folding,
the "shaper is then pressed down on to the base by bringing over the side
quarters and securing one over the other, the flap a being turned up by contact

with the rim "see Figure 3," and is then pasted down, the pressure is then taken
off the shaper plate" when by reason of its flexibility it rises and the bag is then
easily removed therefrom and another one takes its place. Various pitched knives
are used so as to leave a lip of any required extent or depth to form the closing
Hap of envelopes, "see dotted line Figure 1." For "sweet bags the "shaper
plate" is conical or triangular or of any pattern to produce the shape of bag or
envelope required but employed in the inanner before described. It may also be
rigid and have india rubber or metal springs such as D or d. pressing on their
under sides, a sketch of which is shown in Figure 4, so that the "shaper plate
rises when released.

Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what I
claim is
1. In the manufacture of paper bags and such articles as herein described the
employment of a knife such as c to produce the blank A., or the like.
2. In the manufacture of paper bags and such articles the employment of a
flexible shaper plate" such as B, or B arranged and operated substantially as
described.
3. Improvements in the manufacture of paper bags, and other such articles,
substantially as herein described and set forth.
