Convenient diagnostics
Sophisticated systems require a simple, com-

work. The CANMON software tool for Windows
computers depicts the CAN network in a struc-

convenient set-up editor for setting all control

both saving and printing out of the entire CAN

Pivoting frame system ELGUIDER

Function
On ELGUIDER pivoting frame system, the web
changes direction four times, each time by
90°. The system is based on a pivoting frame LÜ
with two path rollers. The imaginary pivot
point is located on the infeed plane. Lateral
web corrections may only be achieved by swi-
veling around this pivot point. The prerequisite
L1 L2
here is always sufficient tension for friction- A-A B-B
locking between the web and the guide roller.
45
Usage 15
15
Due to the optimum utilization of the 45 2 3 4 5
elasticity ranges, the pivoting frame is parti-
cularly
suited for implementation in cramped
conditions. 1
Usage
B-B
The greater the web tension, the modules A-A K
of elasticity and the required correction, the
longer the infeed, outfeed and transfer paths AB
should be designed. Experience has shown
that these paths should be the equivalent of
60 to 100 % of the web width. The sensor
should be located behind the guide roller as 1 3
close as possible. 1 2

ELGUIDER | Steering roller system ELROLLER
Steering roller system ELROLLER

Function
L3
ELROLLER steering roller systems correct the
L1 L2
web position already in the infeed path. They
consist of a fixed base frame and a movable
A-A
guide frame. The latter accommodates one
or two guide rollers and swivels round an
imaginary pivot point on the infeed path. The L4
B-B
pivot point should, on the one hand, be far
enough away from the infeed roller to ensure
that the web correction does not influence 2 1 3 4 5
the infeed roller. On the other hand, it must
be far enough away from the guide roller to
ensure that the elasticity of the web may be B-B
fully exploited but not over-strained. A steering A-A K
roller is termed a proportional actuator. It must
therefore operate friction-locked and may not AB
permit any sliding between the web and the
guide roller.
Usage
ELROLLER systems are always used where
a long entry path is already featured due to
L3
technical process reasons.

Usage
Depending on the space available, steering B-B
rollers may be fitted with one or two guide
A-A
rollers. On versions with one roller, the web
is guided with a wrapping of 90°. On versions
with two guide rollers less wrapping is possi- 2 1 3 4 5
ble. In this case, the web runs at almost the
same level as the outfeed roller. The following
applies when mounting an ELROLLER: the B-B
A-A K
infeed path should be the equivalent of two to
three times the web width, the outfeed path
AB
should be between 50 and 100% of the web
width. The sensor should be positioned behind
the guide roller as near to it as possible. Due
to the short response time, improved actuating
dynamics are achieved.

Turning bar system ELTURNER

L1
Function
Web guiding with ELTURNER turning bar sys- A
tems is based on a simple principle: a bar is A-A
mounted at an angle of 45° to the longitudinal K
and transverse axes while the web runs over
it with 180° wrapping. This has the immediate
effect of changing the direction of web travel AB
by 90°. To correct the web at the same time,
1
the turning bar is displaced in parallel to the
infeed plane according to the actuating signal, 3
A
thus offsetting the web to the side as it runs off.
B-B
B B
Usage 2
The use of turning bar control systems is
recommended when, after the 90° deflection,
an ELGUIDER or ELROLLER system may not be
used due to space restrictions. L2
4
5
Application, turning bar
When the turning bar is used there must be
constant friction-locking between it and the
web at certain points. To protect the web sur- LÜ
face, the friction may be reduced by inserting

an air cushion between the turning bar and the
web. Guiding precision of up to ± 1 mm can
be achieved. To obtain improved corrective
dynamics a guide roller should be implemen-
ted in addition to the turning bar. The distance L2
between the guide and lock rollers should be L1
A-A B-B
the equivalent of half the web width. The sen-
sor should be mounted immediately after the
outfeed roller as close as possible.
2 3 4 5
Application, turning bar with pivoting frame
A combination of pivoting frame and turning
bar causes the web to turn and at the same 6
time ensures precision positioning control in

the range of ± 0.1 mm.

ELGUIDER | Reel station control ELWINDER
Reel station control ELWINDER

Function Unwinding
Typically in production processes
involving moving webs, the unwinding sta-
tion is located at the machine infeed and L1
A
the rewinding station at the outfeed. During A-
unwinding, the reel station is moved via a line-
ar drive to feed the web in the desired positi-
on. On the other hand, during rewinding, the
reel station follows the constantly changing
web position via a linear drive to achieve an
evenly wound reel. 3 1 2 4 5
Usage K A-A
Web guiders with ELWINDER reel stations are
always used if, due to cramped conditions,
an ELGUIDER or ELROLLER system cannot be AB
accommodated.
Application, unwinding
During unwinding, the sensor is mounted on
the machine to define the web set position.
Position acquisition should be located as close
to the final reel station guide roller as possible.
Rewinding
Application, unwinding with synchronous
roller
L1
If, for space reasons, it is not possible to fit
a guide roller to the reel station, it can be A-
designed as a synchronous electrically coupled A
roller.
Application, rewinding
During rewinding the sensor is fastened to
2 4 5 1 3
the reel station to define the set position of
the reel station to the controller. Position
acquisition should be located as close to the A-A K
final machine guide roller as possible. Guiding
path L1 depends on the elasticity of the web.
The larger the transverse elasticity range, the AB
shorter path L1 may be. Experience has shown
that the guiding path should be the equivalent
of half a web width.
