[Communicated from abroad by REINHARD MANNESMANN, of Remscheid, Reimscheid-
Bliedinghausen, in the German Empire, Manufacturer.]
Improved Manufacture of Sheet Metal, Metal Bands, and Wire.
I, OLIVER LMRAY of No. 28 Southampton Buildings Chancery Lane in the County
of Middlesex Fellow of the Institute of Patent Agents do hereby declare the nature
of this invention to be as follows:-
According to this invention sheet metal, metal bands and wire are produced by
first manufacturing solid or hollow ingots into comparatively thin tubes by skew
rolls, and then cutting such tubes in a longitudinal direction at one or more points
so as, when opened out, to form one or more plates or a number of bands or narrow
strips constituting wires, which are then, if necessary, flattened out by passing them
through cylindrical rolls or by pressing,
When manufacturing such plates &c. from hollow ingots or tubes, these are passed
through skew rolls and over mandrils according to the methods described in the
Specification to Reinhard and Mannesmanns Patent No. 9939 of 1886 or in the
Specification to Danns Patent No. 6453 of 1887, until the desired thickness has been
attained, the diameter of the tube being either increased, decreased, or maintained
the same.
The tube thus produced is then cut longitudinally by rotary or other cutters either
as the tube is being delivered from the rolls, in which case the cutters must revolve
with the tube, or the cutting may be effected after the rolling has been completed.
On then passing the plates &c. through cylindrical rolls or through presses for
flattening them, they may be at the same further reduced in thickness.
In manufacturing the plates &c. directly from solid ingots or billets, these are
first converted into tubular form by passing through skew rolls, either with or
without mandrils, as described in the before mentioned Specifications, and are then

page_text: enlarged internally by passing over a conoidal mandril; the outer diameter being
either also enlarged or reduced or remaining the same, until the tube has been
reduced to the required thickness for forming the plates &c.
The required reduction in thickness of the tube may be effected by two or more
.consecutive operations, instead of in one operation.
The cutting open of the tubes may be effected either in a direction parallel to the.
axis, or, when the tube is to be cut into two or more separate parts, in a more or
less helical direction round the axis, in which case the strips or bands so obtained
will be of greater length than the tube from which they are cut. If the cuts are
effected very close together, so as to produce narrow bands or strips, or wire of
rectangular section, these may not require any subsequent flattening out.
By means of the above described manufacture of plates from tubes, the waste
that is produced in the ordinary manufacture of plates by rolling, by the necessary
trimming of the two sides thereof, is avoided.

Improved Manufacture of Sheet Metal, Metal Bands, and Wire.
1, OLIVER IMRAY of No. 28 Southampton Buildings Chancery Lane, in the County
of Middlesex Fellow of the Institute of Patent Agents 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 :-
According to this invention, sheet metal metal bands and wire are produced by
first manufacturing solid or hollow ingots into comparatively thin tubes by skew
rolls, and then cutting such tubes in a longitudinal direction at one or more points
so as, when opened out, to form one or more plates or a number of bands or narrow
strips constituting wires, which are then, if necessary, flattened out by passing them
through cylindrical rolls or by pressing.
When manufacturing such plates &c. from hollow ingots or tubes, these are passed
through skew rolls and over mandrils according to the methods described in the
Specification to Reinhard and Mannesmann's Patent No. 9939 of 1886 or in the
Specification to Dann's Patent No. 6453 of 1887 until the desired thickness has been
attained, the diameter of the tube being either increased, decreased, or maintained
the same.
•
The tube thus produced is then cut longitudinally by rotary or other cutters, either
as the tube is being delivered from the rolls, in which case the cutters must revolve
with the tube, or the cutting may be effected after the rolling has been completed.
On then passing the plates &c. through cylindrical rolls or through presses for
flattening them, they may be at the same time further reduced in thickness.
In manufacturing the plates &c. directly from solid ingots or billets, these are first
converted into tubular form by passing through skew rolls, either with or without
mandrils, as described in the before mentioned Specifications, and are then enlarged
internally by passing over a conoidal mandril, the outer diameter being either also
enlarged or reduced or remaining the same, until the tube has been reduced to the
required thickness for forming the plates &c.
The required reduction in thickness of the tube may be effected by two or more
consecutive operations instead of in one operation.
The cutting open of the tubes may be effected either in a direction parallel to the
axis, or, when the tube is to be cut into two or more separate parts, in a more or less
helical direction round the axis, in which case the strips or bands so obtained will
be of greater length than the tube from which they are cut. If the cuts are effected
very close together so as to produce narrow bands or strips, or wire of rectangular
section, these may not require any subsequent flattening out.
By means of the above described manufacture of plates from tubes, the waste that
is produced in the ordinary manufacture of plates by rolling, by the necessary
trimming of the two sides thereof is avoided.
In the accompanying drawings Fig. 1 is a section and Fig. 2 is a plan of a tube
which may be cut along a parallel to the axis and flattened as indicated by the dotted

page_text: lines. As shewn in the plan Fig. 3, the tube may be cut helically so as to form
a series of screw threads of any desired width, which may be opened out and
flattened.
Having now particularly described and ascertained the nature of this inven
tion and in what manner the same is to be performed, I declare that what I
claim is
The manufacture of sheet metal, metal bands and wire by producing from a solid
ingoi a tube by means of skew rollers and mandrils, cutting this tube longitudinally
or helically, opening up the metal so cut, and flattening and rolling the same,
substantially as described.
