COMPLETE SPECIFICATION.
Improvements in or connected with Glueing Machines.
I, CARL LAUFER, Bookbinder, of 196, Bilker-Allee, Dusseldorf, in the Empire
of Germany, 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 :—
66
This invention for improvements in or connected with glueing machines
relates to a machine for the laying on of glue, in which the quantity of the glue
on the laying on "roller is regulated by the arrangement of a scraping off"
roller in front of the same and has for its object to provide means for regulating
the distance of the "scraping off" roller from the principal roller.
According to this invention the axes of the "laying on " and "scraping off"
rollers are held adjustably apart from one another by means of two pairs of
conical discs mounted with their axes parallel, with the assistance of spring
pressure or the like, so that by a longitudinal axial displacement of the conical
discs of one axis, the distance apart of the rollers is regulated.
The invention is illustrated in the accompanying drawing, in which,
Fig. 1 is a side view of part of a glueing machine to which the improved
regulating device is applied.
Fig. 2 is an elevation of the same with the distance between the rollers at the
maximum.
Fig. 3 a similar view with such distance at the minimum.
Fig. 4 a detail view of a bearing screw.
C
In the horizontal walls of the case a in which the vessel containing the glue
is placed, a hearing 6 for the "laying on" roller e, bearing & for the "scraping off"
roller and the guiding roller g, and bearing & for the guiding roller h are
arranged as shown.
The two ends of the roller e have conical discs kk arranged on their spindle i.
The roller e is adjusted in the bearing 6 by means of screws of which the
one is furnished with a spiral spring ?.
On the axis m of the roller f. conical discs nn' are also mounted, these discs
being parallel with the discs kk¹,
The bearing e for the roller f is opened in order to allow the roller to "give"
when acted upon by the conical discs.
The distance apart of the rollers f and e is assured by the springs o o¹.
The regulating of the distance between the rollers f and e is effected by turning
the screws of the roller e. Hereby the pair of conical discs is displaced
axially in relation to one another, whereby the distance of the roller from
the roller is increased or diminished.
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:-
An apparatus in connection with glueing machines for regulating the distance

page_text: of the "scraping off" roller from the laying on roller, the distinguishing feature
being that the axes m and i of the rollers and e are held adjustably apart by
means of two pairs of conical dises kn and ', mounted parallel to one another,
with the assistance of spring pressure or the like in such a manner that the distance
of the rollers from one another can be regulated by a longitudinal displacement 5
of the conical discs, substantially as described.
