Method of and Apparatus for Automatically Regulating Travelling
Webs, Felts, Wire-cloth, Paper, Pasteboard, and the like.
I, BRUNO MEINERT, of 28 Frabenstrasse, Berlin, Germany, Civil Engineer, do
hereby declare the nature of my said invention and in what manner the same is to
be performed, to be particularly described and ascertained in, and by the following
statement:-
The Invention hereafter described relates to a regulator for automatically guiding
the stuff-rollers of textures, felts, wires, paper, cardboard, and the like.
In the various kinds of industries as above, it is requisite to carry flat lying stuffs,
often of a very tender nature, on long endless ways over, below, or between rollers
towards the respective manufacturing operations, and during this process it frequently
happens from many causes that lateral oscillations of the running stuffs take place,
to regulate which it has been mostly the practice to use the well-known hand
regulating rollers. These latter are insufficient, and efforts have been made to
substitute for them automatic regulator-rollers which guide the stuffs by causing
their edges to run along corresponding projections.
The above means of adjustment has serious disadvantages. The frequent contact
of the projections with the edges of the cloths, felts and the like, even if apparently
ever so trifling, causes a gradual wearing away of such edges, and therefore they
have been very limited in their application.
To avoid the above described method of guiding the webs by their edges is the
main object of the present invention.
According to this invention this is obtained by a uniform distribution of the
operation of the regulating device over the entire surface of the web in contact with
one or more guiding rollers instead of guiding the stuffs only by their edges. This
automatic guiding is obtained by allowing the guiding rollers to share the occasional
oscillations of the web to left or right. By this arrangement the rollers have a
double movement, that is to say they have a movement of rotation, and at times a
slight movement in the line of their axis which latter movement is used to produce
at times an oblique displacement of such rollers so as to direct the stuffs. This
oblique movement can be obtained in various ways as regards the construction of
mechanism, for example as illustrated in the drawings hereto annexed.
The actuation of the oblique displacement of the directing-roller can take place-
Class 1. By the displacement in the direction of the axis of said directing-roller
itself, and-
Class 2. By the displacement in the direction of the axis of one or more auxiliary
rollers that share in the lateral oscillations of the stuffs to be guided, and which
transfer their movements by a suitable mechanism to the directing-roller.

The action of the mechanism effecting the displacement of the directing-rollers, can
moreover be of the following kinds, (sub-divisions) :-
(a) Quickly acting and constantly gearing
for small efficiency of
(6) Quickly acting and periodically intermittent gearing
power.
(c) Slowly acting and periodically intermittent gearing for larger efficiency of 5
(d) Slowly acting and constantly gearing
power.

from the auxiliary rollers.
The regulating device represented in Figures 1, 2, and 3, is for slowly operating a
periodically intermittent motion for putting in gear the mechanism for giving an
oblique displacement to the axis of the regulating roller. The position of the stuff M
which has to be guided is regulated by the roller W, a second roller V (shewn in
dotted lines in Figure 1) may be placed over, or in other convenient position, and
moved with the roller W if required, and if one roller is not sufficient to regulate
the course of the stuff M.
The axial movement of the regulating roller W, which is caused by the oscillation
of the stuff, is made use of to impart an oblique displacement to its axis as
follows:-
The spindle z of the roller W is provided at one end with an eccentric e which,
as the roller W revolves, moves up and down the rocking forked device a to which
it is connected by the screw f. The spindle z z¹ and the roller W have side play in
the bearings o w. The bearing wis carried by a carrying spindle working in a
socket carried on the frame R. The bearing o is carried by a sliding shoe G on
which it is free to turn, thus an oblique displacement either way can be given to the
roller W. The sliding shoe G has two brackets with bosses m m, through which
passes a screwed shaft J. On this shaft J, and between the bosses m m, there is
mounted a wheel S having a screwed boss running on the screwed shaft J, and
having ratchet teeth on each side, of reverse direction. This wheel S is worked by
the pawls k, on the forked device a and moves on the screwed shaft J, taking with
it the sliding shoe G and thereby the bearing o, thus giving an oblique direction to
the roller W. The shaft J is carried between the supports F mounted on the
frame R. The sliding shoe G and thereby the bearing o can be moved by hand by
means of the hand wheel U, the set screw Z being first unscrewed from the shaft J.
The roller W turns in the direction of the arrows, giving an up and down movement
to the device a, so that the pawl k gears with and works the wheel S one way on
the down stroke and the pawl gears with and moves the wheel the other way on

the upstroke, when the slightest displacement takes place or the roler w
direction of its axis, to the right or to the left. In the central position the wheel S
is stationary, as the pawls k and I do not engage with it.
To enable the side displacement of the roller W to cause the pawls k or 1 to engage
with the wheel S, one way or the other, and so move the bearing o, there is provided
on the spindle of the directing roller W, a boss i, having a groove in which works
the forked end of a bell crank lever Q, the fulcrum of which is on the sliding shoe G.
Motion is given to this lever Q by the lateral movement of the spindle and boss i.
The long arm of the lever Q is connected to a sleeve C which slides on a rod d, fixed
on arms projecting from the base plate F. The lever Q and the sleeve C are connected
together by a screw joint. The sleeve C has two spring holders D, D, by which the
fork shaped bent springs b, b, are carried, the tension of which can be adjusted by
the slides b' b. The spring holders D. D. are adjusted on the sleeve by set screws.
According to the direction in which the sleeve C is moved by the lever through
the lateral displacement of the axis of the roller W, the rocking device a is by means
of the springs b, b put into position for catching, either by its tooth k or 1, the
wheel S and so turns it on the shaft J and by coming into contact with the bosses m, m,
moves the sliding shoe G and so sets the axis of the roller W. to an oblique position.
If it is desired that the roller W. should remain in its central position and act only
as a common guiding roller, the lateral displacement of the roller W. is stopped by
fixing the lever Q to the rod d by means of the set screw E.
In order to indicate the action of the apparatus, there is provided a dial plate s
marked with degrees and provided with a pointer h. This dial plate is carried by
the bar L from the columns K, K; the pointer being carried by the shoe G.

The limit of lateral movement of the roller W is governed by the eccentric
adjustable boss i, and the bearing o. H designates the distance of the centre line of
the roiler W above the frame R. N. are vertical centre lines. The double movement
of the roller W is represented in Figure 2 by the oblique arrows, and the oblique
movement is shewn in dotted lines in Figure 4.
By means of the mechanism described with reference to Figures 1, 2 and 3, a slow
intermittent putting in gear of the parts giving the oblique movement to the roller W
takes place.
For apparatus in which the rotation and displacement of the guiding roller requires
a small power (Class 1, Sub-divisions a and b) either a sudden intermittent or a
constantly acting roller displacement mechanism can be applied. A gearing of the
latter kind, for example, can be obtained by transferring the longitudinal displacement
of the axis of the guiding roller W through two friction discs (fixed on the spindle Z
of the roller W) to the wheel S on the screwed shaft J. The wheel S is connected
with the sliding shoe G and thus moves the bearing o either one way or the other,
according to its position against the one or the other friction disc, thus producing the
In this action the respective
oblique displacement of the guiding roller W.
co-operation of the friction discs and the wheel S is a direct and constant, instead of
intermittent one, and therefore the putting into gear is immediate, as the wheel S and
the friction discs-by the rough nature of their surface-bind one with the other
(Class 1 Sub-division a).
In Figures 5, 6, 7, 8, 9 and 10 an arrangement is shewn in which the displacement
of the guiding roller is provided not by the axial movement of the roller itself, but
by the movement of an auxiliary roller at a distance from the guiding roller.
Figures 5 and 6 shew this arrangement applied to the bolting cloth of a paper-making
machine where, as a rule, the guiding roller lies directly in front of two rollers 2 and 3.
According to this arrangement, a pair of rollers V₁ V2 are placed between any two
of the under rollers 4, 5, 6, or 7 carrying the bolting cloth to the breast roller 1.
These rollers V1 V2 are mounted so as to slide vertically in guides f, as shewn in
Figure 7; and also in the direction of their axis horizontally, as shewn in Figure 8,
thus the rollers V1 V2 are borne by the stuff M. In Figures 5 to 10 the destination

page_text: of the parts F, G, H, T, M, P, R, U, W, h, m, o, p, t and z correspond with the
analogous destinations of the so designed parts in Figures 1, 2 and 3. The axis of
the rollers V1 V2 are held by collars in the bearings which are adjustable vertically
on each side of the machine, so that by turning the set screws u, the rollers can be
brought together in the guides C against the stuff M passing between them.
8, s' are
antifriction-rollers to assist the lateral displacement of the rollers V₁ V2. The axle of
the roller V is provided with a strap pulley a, provided with rings. From this
pulley at a strap leads to the three strap pulleys a¹ a² a³, the pulleys a¹ and as being
fast pulleys and a² is a loose pulley. The pulley a³ is firmly keyed on the spindle c on
which is also fixed the bevel wheel 63 and the worm d. The bevel wheel b¹ which is
connected to the pulley a¹ by a sleeve, gears into the bevel wheel 3 by means of the
intermediate wheel 62, carried on the spindle n. All the wheels b¹, 62 ³ are encased
in the casing E. By means of the worin d the movement of the pulleys a¹ and a³ in
either direction is conveyed by means of the worm wheel e to the screwed shaft J
carrying the sliding shoe G the movement being transmitted either direct from
the pulley as to the worm and wheel gear de, or through the pulley a¹ and
wheels 61 62 63.
If each slide C is in the central position, as shewn in Figures 8 and 10), then the
strap is on the loose pulley a² and the regulating device is disengaged; but if the
slide C is moved laterally one way or the other by the running of the stuff M, then
the strap runs on to the pulley a¹ or a³ and causes the roller W to take an oblique
direction. Thus the movement of the regulating device only takes place when the
strap r is on the pulley a¹ or the pulley a³.
When it is desired to effect the guiding of the stuffs by hand, this can be done by
the hand wheel U which is provided for that purpose on the screwed shaft J and
whereby the sliding shoe G can be moved to give the required oblique position to the
roller W.
Having now particularly described the nature of the said Invention and in what
manner the same is to be performed I declare that what I claim is
1st. In the manufacture of textile fabrics, felts, wire-web, paper, pasteboard, and
the like the method herein described of automatically regulating such materials
when passing over, under and between rollers, or cylinders, which method
consists of the employment of the lateral deviations of the material in passing between
or over, or under such rollers to set the regulating rollers obliquely, transversely to
the direction of the motion of the material, substantially as and for the purposes
set forth.
2nd. A regulating roller adapted to be axially displaced by the lateral deviating
motion of textile fabrics, felt, wire web, paper, pasteboard, and the like, when passing
between, or over, or under rollers, or cylinders, one journal of which roller being
arranged to rest upon a suitably shaped slide rest, which by means of a screw nut,
ratchet wheel, pawl and eccentric, or otherwise by a suitable nut roller and its driver
upon the respective journals of the roller can be alternately displaced, for which the
said intermediate parts are set in operation together by the axial displacement of the
regulating roller and by its turning, and thereby causing a corresponding oblique
position of this regulating roller relatively to the web of stuff deviating in the
direction of its width.
