France, Engineer and Patent Agent, "IMPROVEMENTS IN MACHINERY FOR ROLLING
ON EDGE SPIRAL BANDS OF STEEL AND OTHER METAL (A Communication to
me by Leonard Poilvache, and Alfredo Nagelmackers, both of Liége, in the
Kingdom of Belgium)
دو
For the purpose of this Invention, which relates to improvements in machinery
for rolling on edge spiral bands of steel-and other metal, there is used a machine of
the construction represented on the accompanying drawings in elevation in Fig. 1
and in plan in Fig 2, and which consists of two main parts A, and B, the faces of
which are spiral. The parts A, B, are pierced with a central hole through which
is passed a rod or shaft M, on which the band of metal is rolled edgeways.
The two extremities of the spiral A, leave an opening E, through which the
band of rolled metal passes. The parts A, and B, are united by bolts S, and they
can be set more or less apart according to the thickness of the band to be rolled.
The end of the band to be rolled is introduced between the parts A, and B, and
after one revolution of these two parts (the central rod remaining stationary) it
passes through the opening E, and is fixed to the shaft M, in any appropriate
manner,

The machine that we employ for this purpose is represented in the eight figures
of the accompanying drawings of which fig. 1 is an elevation, and fig. a plan,
figs. 3, 4, 5 & 6 different views of its two main parts, and fig. 7 an elevation, and
fig. 8 a plan of a modified form of the machine. In these figures, A & B are the
two main parts of our machine, the plate A and the upper surface of B are
helicoidal. They are pierced with a central hole in which is passed an axis, or
rod M on which the bands of metal are rolled on edge. The pitch of the helix A
forms an opening E through which the rolled band leaves the apparatus. The
parts A & B are united together by the bolts S by means of which they can also be
set nearer or further apart in accordance with the thickness of the band that has
to be rolled and in order that the said band should not be susceptible of warping,
as it passes through the two helicoidal surfaces, but that it should on the contrary
be in a manner drawn forcibly through the parts A & B. After having made a
total or a partial revolution around the axis, the band of metal issues through the
slot E formed by A and it is fixed to the axis M by any appropriate means.
In practice the parts A & B may be fixed, and M rotated, in which case the
latter draws the band through A & B thereby coiling it, since in such case it bears
against the leading roller R or against any other appropriate guide and the rod
will under these circumstances progress in the direction of V to P a quantity at
least equal to the thickness of the band of metal operated on. The rod may also
be fixed, and the parts A & B rotated, or again the rod M may be rotated without
progressing in the direction of its axis, whilst the parts A & B may advance on the
rod without rotating.
The said parts A & B may also be divided in several-segments, as shewn in
figs. 7 & 8, where each is composed of four parts which may be set nearer to or
further apart from the center of the apparatus, whereby the dimensions of the axis
which serves as a core may be changed. For the purpose of coiling metallic bands,
the cross sections of which are not rectangular, the distance apart between A and B
must correspond with the cross or transverse section of the metal to be coiled,
that is to say in such cases the opposite surfaces of the two parts A & B would no
longer be parallel.
We claim as our invention:
A machine for rolling or coiling on edge, bands of metal of any cross section,
and composed mainly of two helicoidal parts A & B, each being made in one or
several parts, of a rod or shaft M passing through the center of A & B and serving
as a core for coiling the band of metal, and of a roller R for the purpose of guiding
the band whilst being coiled..
