Improvements in the Manufacture of Paper and other Bags, and in
Appartaus therefor.
JOSEPH HANDFORD of 40 Church Street Hyde in the County of Chester,
Paper Merchant, do hereby declare the nature of this invention and in what
Inanner the same is to be performed to be particularly described and ascertained
in and by the following statement :-
This invention relates principally to the construction of a former or model to be
employed in the manufacture of bags of paper or other suitable material, whereby
the process of manufacturing such bags is greatly facilitated.
The nature of my said invention and the manner in which the same is to be
performed or carried into practical effect will be readily understood on reference to
the sheet of illustrative drawings hereunto annexed and the following explanation
thereof.
The improved former may be briefly described as consisting of a base plate of
tin or other suitable material to which is hinged near the top a rectangular flap of
tin or other material, and to each extreme edge of the said base plate is hinged a
narrow strip of similar material one end of which is mitred or cut off to an angle
of about forty five degrees. There is also a second rectangular flap hinged to the
base plate just above the other, so that it may fall over the first named hinged flap
and lie flat upon it.
On the annexed drawings
Fig. 1 is a face view of the apparatus showing the side hinged strips lying open
and the two rectangular hinged flaps raised ready to receive the paper.
Fig. 2 is a side or edge view (in section) of the apparatus in this position.
Fig. 3 is an end view of Fig. 1. Fig. 4 a similar view with the first hinged flap
brought down and the side strips folded over it, and Fig. 5 shows the same with
the second hinged flap also folded down over the side strips.
Fig. 6 is a face view of the apparatus closed up in the position shown at Fig. 5.
Fig. 7 is a face view of a completed bag with the bottom turned up and lying
flat on the side, and Fig. 8 is an edge view of the same.
Fig. 9 is a top view of the bag when open.
A is the base plate. B and B are narrow side strips which are hinged to the
extreme edges of the base plate A at each side. These are mitred off at one end
in opposite directions to each other as shown at Fig. 1.
rectangular piece or flap which is hinged near the top
D is the second or upper rectangular piece or flap which
plate higher up at d, and has a hollow d+ formed in it so as
the piece C.
C is the first or lower
to the base plate at c;
also hinged to the base
to clear the hinge of
The method of using this apparatus for forming a paper bag is as follows: A
number of paper blanks of the required form and size having been prepared and
pasted at the edges in the usual manner, one of them is taken and, the former being
in its expanded position with all the hinged parts open as shown at Figs. 1 and 2,
the paper is laid thereon centrally with its upper edge below the hinge c and level
with the top edges of the side hinged strips B and B', and the lower hinged flap C
is brought down onto it. The paper is then folded over this flap C, and the two
side binged strips B and B are brought over and laid flat on the paper (see Fig. 4).
The latter is now opened out and folded back over the hinged strips B and B¹,

page_text: and the second or top hinged flap D is brought down over the paper, thus forming
a fold or crease down each side of the same.
The paper is now folded together over the flap D towards the centre, where one
edge thereof overlaps the other, and they are united by the paste or other suitable
adhesive material.
The fore-finger is now inserted at the bottom inside the bag, and the paper
pressed and plaited along the mitred edges of the side hinged strips B and B', and
the points thus formed are then bent over to the centre and pasted together, as shown
at Fig. 7, and the completed bag can then be slipped endwise off the apparatus, the
bottom lying flat on the side of the bag and two sides creased or folded inwards,
and they are stored for use in this state (see Figs. 7 and 8); but when the bag is
opened for filling it forms a square flat end as shown at Fig. 9.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
First. In apparatus for the manufacture of paper and other bags the com-
bination with an elongated rectangular base plate, of two rectangular flaps
hinged thereto at or near one end, and two side strips hinged thereto along the
extreme edges thereof, such strips being respectively mitred or cut off in opposite
angular directions, substantially as hereinbefore particularly described and
illustrated by the drawings hereunto annexed, and
Secondly. I claim the use or employment of apparatus (such as is herein
described and illustrated) in the manner and for the purpose hereinbefore set forth.
