page_text: rotated by means of the wheels d and the intermediate wheels e, Figure 3. so as to
correspond to the direction and speed of travel of the card board) serves with a
pressure roller 91, Figure 2, pivotted above the second feeding. roller to firmly press
the binding to the edge of the card board. Similar rollers g may be used behind
the pressure rollers g fixing the joint or corner strips in order to more securely
attach the latter.
The pressure rollers 9" may also be used to emboss the strip which has been pasted
on, or the card boards themselves, the rims having for this purpose suitable embossing
surfaces. It is then preferable not to form the back feeding roller solid, but as an
axle c to which are keyed the longitudinally adjustable feeding rollers ff1 corre-
sponding with the pressure rollers g¹¹. By adjusting the corresponding embossing
pressure rollers g" the embossing may be produced on the bare card board beside
instead of on the strips. The rollers ff may also be used for embossing the under
side of the card boards, their rims being for this purpose provided with suitable
embossing surfaces. Figures 4 and 5 show two enlarged patterns.
The adhesive material may be on one side of the strip before the latter is wound on
the rollers, or the machine may distribute it automatically on the strip.
In the first case it is necessary to moisten the adhesive side and for this purpose
water vessels n, figure 10, are attached to the supports carrying the strip rollers m
and m². Each of these vessels contains a wick n' the upper end of which hangs out
over the edge of the vessel so as to moisten the strip which is fed to the pressure roller,
see figure 2.
In the 2nd case, the apparatus shown in Figure 11 and 12 is used. It consists of a
vessel 9 containing adhesive material to which is attached sidewards a cylinder o the
end of which is closed. This cylinder has a slot o¹ on its upper side extending over
nearly the whole of its length, and it is surrounded by a sleeve p having slots p² the
different lengths of which correspond to the various widths of the strips used.
This sleeve is turned so that above the sloto is placed that slot p¹ the length of which
corresponds to the widths of the strip to be used. On the vessel J. is arranged a
pins above the sleeve p on which is then pushed a roller s¹ the width of which
also corresponds to the width of the strip. The diameter of this roller, is of such
a size that when the roller is placed exactly over the slot p¹ it covers nearly the
whole of the latter, thus preventing a superfluous escape of adhesive material.
When this roller is rotated by the strip fed over it, figure 2ª it carries adhesive
material from the slot p¹ to the lower side of the strip. This apparatus may be
slightly modified by dispensing with the roller s' and feeding the strip direct over
the sleeve p. By properly adjusting the latter the orifice at p may be so regulated
that exactly as much adhesive material, as is required is taken up by the strip by
adhesion.
The bolt on the side of the vessel q, figures 18 and 11, serves for fixing the latter
to the support carrying the strip rollers m and m¹ respectively.
Having now particularly described and ascertained the nature of our said inven-
tion and the manner in which the same is to be performed, we declare that what,
we claim is:-
In a machine as patented under No. 6505 of 1887 for covering the corners and
binding the edges of card board boxes.
1.) The substitution for the horizontal strip rollers (k) on the card board guides, of
strip rollers m¹ placed with their corresponding pressure rollers g¹ vertically above the
edges of the sheet of card board so that by proper adjustment only part of the width:
of the strip is pressed to the upper side of the card board.
2.) In combination with the before mentioned pressure rollers g¹ folding grooves l
behind them, of such shape that the part of the strip protruding over the edge
of the card-board is pressed downwards, bent over and pressed against the under
side of the card-board in order to bind the latter.
3.) The addition of a second feeding roller consisting in certain case of an axis c with
adjustable feeding rollers attached to it, in combination with pressure rollers g¹ above

page_text: it to more securely fix the pasted on strips, and if desired to emboss the latter or the
bare cardboard beside it.
4.) In combination with the strip rollers m m' and the pressure rollers g g¹ the
arrangement of an apparatus for distributing the adhesive material on the strips,
consisting of a vessel q containing the adhesive material and carrying the slotted
cylinder o with the sleeve p having slots of varying lengths and with or without the
rollers, distributing the adhesive material.
