page_text: I EDGAR KÖNIG of the firm of König and Bauer of Kloster Oberzell near
Würzburg 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 :-
This Invention has for its object to provide simple apparatus as hereinafter
described whereby paper or other fabric in sheets or in a continuous web may be
turned or have the surfaces thereof reversed without altering the direction of
motion or whereby the direction of motion may be altered without reversing the
surfaces.
And in order that my Invention may be clearly understood I shall now proceed
to describe the same with reference to the accompanying drawings.
Figures 1 and 2 of which represent in elevation and plan respectively an
apparatus constructed according to our invention for reversing the surfaces of
paper or other fabric without altering the direction of the motion thereof and
Figures 3 and 4 are similar views of an apparatus for altering the direction of
motion of paper or other fabric without reversing its surfaces.
Referring to Figures 1 and 2 W represents the surface over which the paper or
other fabric to be turned is caused to travel and which may consist of any suitable
polished material such for example as steel plate. This surface has a treble curve
so that it appears as if it were composed of two inverted halves of a pyramid with
rounded edges. To facilitate the passage of the fabric from the first half pyramid
to the second half pyramid the two halves are curved slightly at x where they join
and to enable the web of endless paper or the guiding tapes for sheets of paper to
pass round or be pressed into this curve I provide the rotary spindle R so arranged
as to leave a sufficient space between it and the surface W for the free passage of
the tapes and the paper. The turning surface W is made of a single piece of sheet
metal suitably curved or bent.

page_text: The tapes employed for guiding cut-sheets of paper through the apparatus pass
from the roller a over the surface of the turning device W making a turn of 90°
on one half of W and passing thence behind the spindle R onto the other half
of W so that when they reach the roller d they will have made a complete turn
of 180° in their passage from the roller a.
The tapes pass thence from the roller d to the roller a being conducted by guide
rolls qpq p and q p² and as the second half pyramid of the surface is inverted
the tapes cross so that the upper taper 1 returns from q' to p³ the central tape r
from to P, and the lowermost tape from q' to p'.
When the paper or fabric to be turned is in sheets they pass between the
receiving rollers a and b from whence they are conducted by the tapes r onto and
over the surface of W the tapes causing them to lie close to the said surface. The
sheet of paper while it continues to fit the shape of W, turns in such a manner
that after having passed beyond the spindle R is raised out of the normal plane at
an angle of 90° and when it has passed between the delivery rollers c d (that is
when it leaves the apparatus) it will have turned 180° the side of the sheet which
was turned downward when the sheet entered the apparatus being now turned
upward.
An endless band or web of paper may be turned exactly in the same way except
that if the apparatus be designed for turning endless bands only, the aforesaid
carrying tapes may be dispensed with.
The rollers a b c d and the spindle R are rotated at an equal speed by means of
the gearing k k¹ m and n the spindle R being connected with the driving wheels
on the rollers a b by the bevel pinions ¹, a longitudinal spindle and spur
wheels n from whence motion is transmitted to the delivery rollers c d by another
longitudinal spindle and a second pair of bevel pinions kk.
It will be understood that an apparatus constructed substantially in the same
manner as that hereinbefore described may be employed where it is required to
change the direction of motion of a sheet or endless band of paper the same
remaining in the same plane, the paper being then temporarily turned out of its
normal plane at an angle of 90° so that it may undergo the change of direction
more easily.
Figures 3 and 4 of the drawings represents in plan and elevation respectively an
apparatus arranged to change the direction of the paper to an angle of 90° at the
point where spindle R is situated; the paper after leaving the portion W of the
guiding surface advancing along the second portion W of the guiding surface
which is not inverted as in the arrangement Figures 1 and 2 but remains in the
same position so that the upper or front side of the paper remains unturned.
In this apparatus the two portions W and W₁ of the guiding surface are
permanently connected while it is advisable to separate the two sets of carrying
tapes so that the one set starting from the receiving roller a may be carried over
the surface W and back to the said roller over the spindle R and guide rolls p³ p';
whilst the other set of tapes are conducted in the same way from the roller c over
the surface W¹ and back to the roller c over the spindle R and guide rolls q³ q*.
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-
First Apparatus for turning paper and other fabric consisting of a guiding
surface constructed and arranged as herein before described in combination with a
guiding spindle arranged parallel to the centre line of the said surface and in
combination or not with guiding tapes whereby the paper or fabric in its passage
through the apparatus is turned 180° out of its original plane (ie, turned over)
whilst the direction of its motion remains unaltered substantially as hereinbefore
described with reference to Figures 1 and 2 of my drawings.

paper or other fabric without reversing the surface thereof consisting of the guide
surface W W¹ and roller R arranged and operating substantially as hereinbefore
described with reference to Figures 3 and 4 of my drawings.
Third: The general construction and arrangement of parts constituting apparatus
for turning paper and other fabrics as hereinbefore described and illustrated by
Figures 1 and
of my Drawings.
