MACHINES A communication to me from abroad by J. H. Gilljam of Laurensberg

The improvements relate, Firstly to peculiar means for guiding the dividing
bands and the arrangement of the taking off and rubbing apparatuses
(Nitschelwerke)
Secondly, to the arrangement of the dividing bands for dividing the fleece, and
Thirdly, to the peculiar form of the grooves in the dividing cylinders
The fleece combed off from the doffer by the doffing comb passes between the
dividing cylinders and dividing bands where it is divided by the crossing of the
said bands. One half of the divided fleece goes with one set of the dividing bands
upwards over an upper tension roller, the other half goes with the other set of
dividing bands downwards under a lower tension roller, the strips of fleece are
taken off opposite these tension rollers by suitable taking off and rubbing
apparatuses (Nitschelwerke) whereupon each set of empty dividing bands return
to their appropriate dividing cylinders over suitably placed guide rollera.
The position of the taking off and rubbing apparatuses (Nitschelwerke) opposite
to the tension rollers is of considerable importance because at the points of contact

page_text: of the dividing bands with the taking off and rubbing apparatuses (Nitschelwerke)
a cleaning of the said dividing bands takes place by reason of the motion of the
taking off and rubbing apparatus Nitschelwerke) at those points being in directions
opposite to those of the bands. The dividing bands are thus not seized violently
because they yield at the points of contact so as to avoid a stronger pressure.
The dividing bands are so arranged that for eaclı strip of fleece to be formed two
dividing bands run in one groove side by side. These bands are crossed or twisted
at certain parts the one to the right and the other to the left
This opposite crossing or twisting imparts to the said bands a tendency to
separate from one another and to lay always close to the edges of the grooves in
the dividing cylinders By these means the greatest possible exactitude in
dividing the fleece is obtained because the narrowing of the dividing bands by
wear and lengthening through the constant passage past each other of the bands
for forming each strip of fleece is continually equalized
The laying of the dividing bands against both edges of the grooves in the
dividing cylinders and the separation from one another of the dividing bands
which belong together can be assisted by grooves of a roof shaped section formed
in the dividing and guiding rollers or by special mechanical apparatuses for
separating the dividing bands
Instead of the two dividing bands for forming a strip of fleece a single band of
half (or less) the breadth of the groove can be employed which single band in that
case passes twice round the dividing cylinders and rollers.

The improvements relate, Firstly, to peculiar means for guiding the dividing
bands and the arrangement of the taking off and rubbing apparatus
(Nitschelwerke)
Secondly, to the arrangement of the dividing bands for dividing the fleece and
Thirdly, to the peculiar form of the grooves in the dividing cylinders
Fig 1 of the drawing shows a vertical section through the fleece dividing
apparatus. Fig 2 a section on the line of figure 1, and Fig 3 shows one form
of the grooves in the dividing cylinders B and C
The fleece combed off from the doffer P by the doffing comb A passes between
the dividing cylinders B and C and the dividing bands D and E which pass round
them where it is divided by the crossing of the said bands. One half of the
divided fleece goes with one set of the dividing bands D upwards over an upper
tension roller F, the other half goes with the other set of dividing bands E down-
wards under a lower tension roller G, the strips of fleece are taken off opposite
these tension rollers by suitable taking off and rubbing apparatuses (Nitschelwerke)
H and I, whereupon each set of empty dividing bands D and E return to their
appropriate dividing cylinders B and C over suitably placed guide rollers L and K
the dividing bands D passing between the dividing bands E and the dividing
bands E between the dividing bands D.
The positions between the taking off and rubbing apparatuses (Nitschelwerke)
H and I, opposite to the tension rollers F L, and GK respectively, is of considerable
importance because at the point M of contact of the dividing bands D with the
taking off and rubbing apparatuses (Nitschelwerke) H and at the point N of
contact of the dividing bands E with the taking of and rubbing apparatus I
a cleaning of the said dividing bands D and E takes place by reason of the motion
of the taking off and rubbing apparatuses (Nitschelwerke) H and I at those points
being in directions opposite to those of the bands
The dividing bands are thus not seized violently, because they yield at the
points of contact M and N so as to avoid a stronger pressure. The dividing
bands are so arranged that for each strip of fleece to be formed two dividing
bands run in one groove side by side, see figure 2. These dividing bands are
crossed or twisted on their way from K to C and from L to B, the one to the right
and the other to the left. This opposite crossing or twisting imparts to the said
bands a tendency to separate from one another and to lay always close to the edges
of the grooves in the dividing cylinders B and C.
By these means the greatest possible exactitude in dividing the fleece is attained
because the narrowing of the dividing bands by wear and lengthening through the
constant passage past each other of the bands for forming each strip of fleece is
continually equalized
The laying of the dividing bands against both edges of the grooves in the
dividing cylinders, and the separation from one another of the dividing bands
which belong together according to the narrowing thereof can be assisted by

page_text: grooves of a roof shaped section (see figure 3) formed in the dividing and guiding
rollers or by special mechanical apparatus for separating the dividing bands.
Instead of the two dividing bands for forming a strip of fleece a single band of
half (or less) the breadth of the groove can be employed which single band in
that case passes twice round the dividing cylinders and rollers B, F, L, or C G K
or a single band of nearly the full width of the groove may be employed.
Having now described the nature of the said invention and the manner in which
the same is to, or may be carried into effect, I would have it understood that what
I claim as the improvements in continuous fleece dividing machines, by the within
in part recited Letters patent is
First, The arrangement of two separate dividing bands running in one groove
as hereinbefore described
Second, The arrangement in one groove of a single band of half the breadth of
the said groove such band being passed twice round the dividing cylinder and
rollers as bereinbefore described.
Third. The employment in the groove of a single band of nearly the same width
as the said groove as hereinbefore described.
Fourth, The groove formed substantially as hereinbefore described and illustrated
in the drawings, whereby the bands are caused to lay as close as possible against
the two edges or sides of the said groove.
Fifth, The arrangements whereby two bands as set forth in the above first
claiming clause, or one band as set forth in the above second and third claiming
clauses are guided over-the-cylinder C.and rollers G. K. and over the cylinders B
and rollers LF as hereinbefore described and illustrated in figures I and 2 of the
drawings
In witness whereof I the said Lorentz Albert Groth have hereunto set my
hand and seal this twenty third day of April A.D. one thousand eight.
hundred and eighty threo.
