The guide I5, providing upper and lower mem-bers I6 and I1, respectively, having the groove I8
therebetween, is suitably supported from the
overhead support I0 by the screw member I9.
The continuous tape 20, Figure 17, Comprising
the metal strip 2I and the paper strip 22 secured
thereto is adapted to fit within the groove I8 of
the guide I5. Said tape prior to entering the
groove may pass through straightening rollers
23, it being understood that said tape will most
likely be supplied in the form of a large roll and
therefore said straightening rollers will have the
effect of substantially eliminating the curvature
which would otherwise exist in the tape. The
metal strip 2I of the tape is located in the base
of the groove, as clearly shown in Figure 4, which
thus makes possible the cutting out of portions
of the paper strip 22 to form tabs 24. Cutting
of the paper strip is effected by the rectangular
knife member 25 pivotally supported at 26 and
suitably actuated by rod 21. The knife 25 is
adapted to operate within a substantially square
space 28, Figure 9, formed in the guide I5, it
being understood that the several edges of the
knife will be approximately parallel to the ad-l
jacent edges of said space. Positioned centrally 30
of said space is a backing member 30 suitably
supported from_ the upper member I6 of the
guide in a manner to permit yielding movement
of the backing member. Said backing- member is
somewhat smaller than the knife and by reason
of the bent portion 3I the said knife may travel
in an upward direction some distance past said
member. Oscillating movement is imparted to the
knife 25 periodically by actuation of rod 21 and
accordingly it will be understood that substantially 40
square portions are cut out of the paper strip 22.
At the forward end of the guide I5 there is
located means 32 for applying an adhesive such
as glue to the undersuriace of each tab 24. Also
located to the forward end of the guide is mecha
nism 33, Figure 2, for severing the continuous
tape along a line 34, Figure 17, which approxi

Referring to the drawings, particularly Figures
55 l and 3, the structure of the invention is adapted
to perform the last operation in the closing and
fastening of a filled ba'g when said fastening is
accomplished by a tin-tie strip and accordingly
it will be understood that a complete machine,
60 for example, of the semi-automatic type, will
include means for gauging the height of the filled
bag to bring the contents thereof to a predeter
mined level, means for collapsing the open end
of the bag, and means for folding said collapsed
65 end to form a folded portion which will project
vertically from the top of the bag. Following the
last folding operation the bag is then presented
to the apparatus of the present invention, which
preferably depends from an overhead member

rality of uprights such as II. Secured to the

the bell crank lever 40. The lower arm of said
lever is provided with pin 4I adapted to contact 60
the extending end 42 of the lever 43 suitably
pivoted at 44 to means depending from the guide
I5. The forward end 45 of said lever is opera
tively associated with the cutting knife 46 suit
ably secured to block 31 by means of the face
plate 41. The knife 46 is adapted to operate with
respect to a stationary cutting blade 48.
In operation of the structure above described,
it will be assumed that a length of tape 20 has
been fed from theforward end of the guide I5.

The cutting mechanism is
therefore located a short distance forwardly of
the end of the guide I5. As the bell crank-lever
48 nears the end of its oscillating movement, the
pin 4| will strike the end of lever 43 to cause
downward movement of knife 46, which actuation
86 located between the depending arms 88 and
which portion provides the gripping member 81.
Extending through the journalling ends of mem
ber 85 and projecting from the ends thereof,
Figure 12,- is a shaft 88 adapted to have axial
movement and forme'd with spaced slots 89. The
offset portion 86 of member 85 is also provided
with a slot within which is pivotally supported

However, the gripping members are caused to

anvil provides a flat surface | I5 extending for the
width of the bag and a shoulder ||6 adapted to
have contact with the metal strip 2| of the con--
tinuous tape to thus hold the tape properly aligned
with respect to the anvil.
As a result of the
counter-clockwise oscillating movement of the
of said tab during the feeding of the tape to
locate a length of said tape over the bag. The
structure above described has been designed so
that the paper tape will be centrally positioned
with respect to the bag and since an adhesive has

cutting mechanism immediately receding follow

portion of the tape projecting beyond the same
and which will be readily gripped by the grip
20 ping fingers 60 and 62 at the start of the next
operation of the machine. It will also be under
stood that cutting of the tab along line 34

adhere to the top of the bag. As previously ex
plained, an adhesive is applied to the underside

The last operation in the closing and fasten
assembly comprising the gripping members, the
ously said gripping members are rotated. This
10 rotation takes place against the tension of the
coil spring ||0 and results by reason of the fact
that roller |09 is in contact with stop |'| |.
Following the labove operation on the folded
25
of the strip, securely fastening the folded por
will leave the rear end projecting beyond the
side of the bag which together with the forward
projecting end of the tin-tie will form the fas
tening means for releasably securing the folded
portion to the top of the bag. As shown in Fig
ures 5 and 13, the gripping members 81 and 94
hold the folded portion in a position horizontal
and adjacent the tin-tie strip which is held in
contact with the anvil H4. More particularly
it will be observed that member 81 is located
between the tin-tie strip and the folded portion
of the bag.
The projecting ends of the tin-tie strip are
bent into a fastening position by fingers |20,
each having pivotally secured thereto a link |2|
having a pivotal connection at |22 to the anvil
H4. Pivotally secured to the upper end of each
finger |20 is a lever |23 suitably fixed to shafts
|04 journalled in bearings |4. Also fixed to_ each
been previously applied thereto, it is only nec
essary that said tape be forced into contact with
the top of the bag. This is accomplished by the
member |28, Figure 16, having a rounded por 15
tion |29 at the lower end thereof. rl’he upper
end of said member is suitably fixed to rod |30,
pivotally supported by shaft |3l, journalled in
bracket |32.
The coil spring |33, conñned be
tween rod |30 and one arm of ’said bracket yield 20
ingly biases said member |28 in a direction in
wardly, Figure 3, where said member will en
gage a stop, locating the same in a vertical posi
tion. Bracket |32 is provided with an upright
portion |34 having formed therein an elongated
slot |35. The support |36 is suitably secured to
the underside of member' l0 and it will therefore
be seen that the bracket and member pivotally
supported therefrom are mounted for vertical
reciprocating movement, which is imparted 30
thereto by actuation vof lever |31.
While the folded portion of the bag is still
held by fingers |20 the lever |31 is caused to move
downwardly and accordingly similar movement
will be given to the member |28. The rounded 35
portion |29 of said member will be caused to
contact and travel over the .paper tab |24,
it being understood that continued downward
movement of member 28 will cause the same to
travel outwardly, which travel is permitted by 40
reason of the pivotal support of said member.
