COMPLETE SPECIFICATION,
Apparatus for the Manufacture of Helically Twisted Wire
and ribbon.
We, CARL KNAPPWURST, Deputy-Director, and HERMANN TRAPPE, Manager of
Works, both of Bahnstrasse, Gerresheim, 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 :—
This invention relates to the means for imparting to certain kinds of wire or
metal ribbon a helical twist, and is applicable to wire of lat, triangular, square ribbed
and other non-circular section.
In the accompanying drawings Fig. 1 is a side view and Fig. 2 a plan of a
machine embodying my invention.
The machine chiefly comprises a feed drum or spool h adapted to turn on two
axes at right angles to each other, an exchangeable guide f connected with the casing
or frame of the said drum, and a receiving drum t adapted to draw the wire through
the said guide.
The axle of the feed drum h carrying the wire is mounted in a casing g provided
with journals or hollow pivots z and 21 at right angles to the axis of the drum; one
of the said journals carries a driving pulley a, while the opposite journal is hollow
throughout its length and serves to guide the wire to be twisted.
The two journals are mounted in a pair of axle bearings, as shown, and the
receiving or winding drum t is mounted near the delivery end in a convenient
position, so that the wire can be drawn through the guide f by turning the drum on
its axis.
In the example shown by the drawings, the axle 6 of the drum t is set in motion
by means of the belt-pulley a, through the intermediary of a stepped cone S mounted
on the journal 2¹, a countershaft w and bevel wheels r.
By means of the stepped cones the speed of the drum t relatively to that of the
journal z¹ may be varied, and consequently also the twist of the wire passing through
the guide f.
The guide or mouthpiece f is fixed to the delivery end of the journal z¹ and has
an axial opening which corresponds to the profile of the wire, which will be twisted
between the mouthpiece f and the winding drum t.
The winding drum is preferably adapted to slide along the axle b, either by hand,
or by automatic mechanism, which imparts to the drum a periodical to-and-fro
motion, in order to form uniform layers of wire on the winding drum t.
Having now particularly described and ascertained the nature of our said invention,
and in what manner the same is to be performed, we declare that what we claim
is :-
1. Machinery for helically twisting ribbon or wire of angular or ribbed profile,
comprising in its construction a casing g or frame provided with a hollow journal zi
and carrying at its extremity an exchangeable mouthpiece or guide f, a feed drum or
spool mounted in the said casing or frame and adapted to turn on its axis, a
winding or receiving drum t adapted to receive the wire from the said mouthpiece,
and means for imparting to the said casing or frame and to the winding drum rotary
motion on their respective axes substantially as described.

page_text: 2. A wire twisting machine coniprising in its construction a revolving guide or
mouthpiece, a winding or receiving drum, and means for cominunicating the rotary
motion of the said mouthpiece to the said drum at a variable speed, substantially as
described and for the purpose specified.
3. A wire twisting machine constructed and adapted to operate, substantially as
described and illustrated by the drawings.
