MACHINE FOR HANDLING:v STRIP MATERIAL
Joseph Ettl, Plainfield, N. J., assignor to Potdevin
Machine Company, Brooklyn, N. Y., a corpora
tion of New York
Application 'April 24, 1936„ sénat-No. 76,151
13 Claims.
This invention relates to machines for apply
ing adhesive material, such as glue, varnish and
»the like to the face of paper or other material
fed through the machine.
5
In machines of this character trouble is ex
perienced in keeping the face of the blanket>
‘roller in good condition, the glue, varnish or other
material used being quick drying 'so that when
the machine stands idle the adhesive dries up
10 and owing to the difficulty in removing this dried
material there is sometimes long delay before the
machine can again be operated.
It is one of the objects of the present invention
to provide a construction wherein the disadvan-4
15 tages above referred to are eliminated by the'
provision of a blanket roller, for applying ad
hesive to the strips, which can be'moved away
rotating in an adhesive solvent contained in a
solvent tank 28. It will be obvious that when the
hand lever 23 is manipulated the arms 24 will
be raised and lowered thereby raising and lower
ing the brush 26 into and out of contact with the \
blanket roller I5. In this movement of the brush
it will be appreciated that the gear 20 will move
about the axis of shaft I8 or, in other words,
will roll around the pinion I9 so that the drive
is not interrupted. The shaft 2| and consequent
ly the brush 26 is driven through gear 25 meshing
with pinion- I9.
.
”f`
The blanket roller I5 carries a removable blan
ket one end of which is secured to the roller
by means of a clamp 36 pivoted at 31 and latched
in clamping position by the latch 38. The other
end of the blanket is wound about a rod or roller
from the roller which applies the adhesive to the _ 39, and tightened by means of „nut 4I|,_reverse

rotation of which is prevented by pawl 4| and
and when so positioned a brush or other roller
carrying a solvent for the adhesive is brought

from roller 32 which is immersed in a tank 33 of 25

Other objects of my present invention will be
manifest from the following description and the
accompanying drawings, in which drawings:

device; and

Referring to the drawings in detail, I 'designate
a frame or support for the device, the upper end
of which is provided'with a pulley 2 mounted on
> 35 shaft 3 and driven from a suitable source of power
C(not shown) through belt- 4l

The shaft'3 carries a pinion 5 meshing with
pinion 6 mounted on shaft 1 on the machine
frame'. This pinion 6 engages a gear 8 mounted' -40 on shaft 9, the shaft y9 also carrying a feed roller

’
The gear 8 meshes with a gear II mounted
on shaft I2, this shaft also carrying blanket roll
er I5. The shaft I2 is supported in the forked
4_5 ends of arms I3 pivotally mounted on stub shafts
I6 in the frame ofthe machine so that the
blanket roller I5 may be moved away from the
íeed roller I0, as will be hereinafter ‘pointed out.
'I'he gear || meshes with a gear I1 mounted
50 on a‘shaft'lß, this shaft also carrying a pinion I9
meshing with gear 20 on a shaft 2|.
Mounted on the shaft I8 is a hand lever 23,
this shaft also carryingA spaced arms 24 which
' constitute supports or bearings for a shaft 2|.
_55 The shaft 2| carries a roller or rotary brush 26
the adhesive, and applies the sameÀ to the blan
ket 25 of the roller I5 when strips are being
fed through the machine, the blanket in turn
transferring the adhesive to the strip of material
in a. well known manner. The adhesive-applying 30
roller 3| and the tank 33 are provided with the
usual adjusting nuts 34 and 35, respectively.
It will be appreciated that the brush 26 is to
be rotated only whenv it is-desired to clean the
blanket of the blanket roller and `when no strips 35
are being fed to the machine. To provide for such
operation a clutch 43, carried on the shaft 2|, is
adapted to be manipulated through lever 44, piv- ~ otally- mounted at 45 on an arm 45’ attached
to the bottom of the tank 28, one end of this lever 40
being attached to the clutch and the other end
to a transverse lever 46. This lever 46 is provided f
at its outer end with a handler 41 and notches
48 adapted to lock the clutch in and out of clutch
ing position, as will be obvious.
‘
45
The free ends' of .the arms I3`which support
the blanket roller I5 and gear _II’are ladapted
to be engaged by cam 49 _ñxed to shaft 50, this
shaft being rocked through the medium' of a
double foot pedal 5|. It will be obvious that as 50
this pedal is rocked the blanket roller I5 and the
gear/II will be raised and lowered slightly. The
teeth on the gears 8 and I I are out slightly deeper
than usual to permit of this movement of the
gear || without the gear becoming entirely dis

engaged from the gear 8. It will be appreciated ‘ away from said adhesive-applying roller, and a
that in raising _and lowering the blanket roller cleaning roller adapted for movement in an
I5 the same follows an arcuate path about the arcuate path into and out of engagement with
fulcrum I5 so that the blanket roller I5 will be said blanket roller for cleaning the surface
moved into and out of contact‘with the adhe
sive-applying roller 3|.
Although the operation of my improved device
will be readily understood from the foregoing de
scription of the apparatus, I will nevertheless for
the purpose of clarity here briefly describe the
same.
'
As the strips are fed to the machine from the
table 52 the same will be received between the
feedroller I0 and blanket roller I5, the forward
15
end of the strip being engaged `by grippers 53
on the feed roller in the usual manner.
As the
strip passes between the rollers III-and I5Lit re
ceives adhesive from the blanket of roller I5,"the
adhesive having ñrst been transferred to 'the
20 roller I5 from the tank 33 by the adhesive-apply
ing roller 3|. The strips are then discharged
upon a conveyor belt 54 for delivery from the
machine in the usual manner.
After the desired number of strips have passed
through the machine the operator steps on the
foot pedal 5I to rock the same clockwise thereby
permitting the shaft I 2 carrying the blanket
roller to be lowered to disengage the blanket roll
er from the adhesive-applying roller. At- the
30 same time the operator manipulates the hand
thereof when the blanket roller is out of con
