System Orientation
SYSTEM
The system consists of feeders, cables to each feeder, interface
control box, PTU (pneumatic threading up),
input yarn tensioners and external accessories such as bobbin
break sensors and bobbin change detectors.
INTERFACE
This control box handles all communication between feeders
and machine via the CAN-bus system.
The control box also distributes 290 VDC and 24VDC from the
machine to each feeder.
FEEDER
The feeder consists of:
• Motor and control unit
• Spoolbodywith4independentlyadjustablengerpairs
• Pick length control stopper magnet
• Yarn store sensor
• Positioning sensor
• Winding sensor
• Bobbin break sensor
Spool body circumference, yarn store size and stopper
unit are mechanically adjusted on the feeder.
All other settings are carried out on the weaving
machines terminal and transmitted to the feeder through
the CAN bus.
The permanent magnet motor is controlled from the
control board situated under the top cover.
At feeder start-up, the number of windings on the spool
body is controlled by the yarn store sensor which
indicates the outer limit of the yarn store. The number of
windings supplied to the yarn store is continuously
counted by the wind-on sensor whilst at the same time
the number of windings removed from the yarn store
is counted by the winding sensor. For optimal regulation
the pattern information is transferred to each feeder
a few picks in advance.
The weft length is equal to the spool body circumference
multiplied with number of windings removed
during one insertion. The stopper magnet pin is opened
at a requested machine-angle by reading the anglebus
and closed directly after the second last winding sensor
pulse. The stopper magnet is driven in both directions
electrically, but held in closed position after the power is
switched off.

The required pick length is the deciding factor when calculating the spool body circumference and the
number of windings for each pick. The table below indicates the pick length ranges that can be obtained
from different numbers of windings. To calculate the appropriate spool body circumference / number of
windings per pick, proceed as follows:
1. Determine the required pick length (drawing-in width plus waste).
2. Using the table below determine a pick length range that covers the required pick length.
3. The number of windings necessary to obtain the required pick length will be found in the left hand
column. Adjust the spool body to the required circumference as follows:
Stopper unit
positioning screws
1,0 mm
Eyelet
Move the stopper unit to its uppermost position before any adjustments are carried out.
Adjust each finger in turn, first the fixed finger then the yarn transport finger. Only loosen the screw
sufficiently to move the finger, excessive loosening gives faulty values. When adjusting the yarn transport
fingers the winding disc eyelet must be aligned with the centre of the finger being adjusted.
YARN TRANSPORT FINGER ADJUSTMENT:
1. Align the winding disc eyelet with the finger to be adjusted.
2. Loosen the screw.
3. Insert the short end of the transport finger guide between the fixed finger and
the yarn transport finger.
4. Adjust the yarn transport finger towards the fixed finger until the guide is felt.
Then thighten the screw whilst holding the guide and finger in place.
FIXED FINGER ADJUSTMENT:
1. Loosen the screw.
2. Adjust the finger using the circumference scale on the front plate as a reference.
3. Re-tighten the screw.

Adjusting N/R rotation and yarn separation
Ref. no. 31-8939-0201-05/1805
1131 X2
N/R Rotation and Yarn Separation Adjustment
C
B
E
A
D
This adjustment is carried out by locking the inclined hub in position and then revolving the winding disc in
a clockwise or anti-clockwise direction.
Proceed as follows:
1. Insert a three millimeter socket key (or similar object) into the hole (A) in the cone at the front of
the spool body.
2. Whilst asserting a slight inward pressure on the key, revolve the winding disc until the key is felt to
lock into position.
3. Firmly grasp the spool body* and rotate the winding disc in the required direction. For normal
rotation rotate the winding disc in a clockwise direction and for reversed rotation in an anti-clockwise
direction. The more the winding disc is rotated the larger will be the yarn separation.
4. Point B on the front plate is the reference point for adjusting separation. When point C is aligned
with B the yarn separation is set at zero. By aligning D or E with B the yarn separation is set at
maximum.
Do not set a larger yarn separation than necessary for the yarn count being used.
* Failure to hold the spool body in position when adjusting yarn separation will result in damage to the
stopper magnet pin.

Balloon Control/Threading
To ensure optimal yarn performance between
the feeder and the weaving machine it may be
beneficial, especially when weaving heavier
yarns, to use a cone for balloon control. During
the initial installation the cone should be
adjusted to the outermost position, then, with
the machine running, slide the cone inwards
towards the feeder until the optimum yarn path
is obtained. The cone should then be locked
into position.
Before threading the feeder it is necessary to
remove any yarn that may be on the spool body.
To do this the magnet pin must be opened. This
can be performed using any of the following
methods:
1. A short push on the yarn release button
will release one winding.
2. By pushing the yarn release button and
keeping it pushed the magnet pin will
remain open as long as the button is
pushed.
After the magnet pin has been opened any yarn
on the spool body can be removed.
To thread the unit proceed as follows: *
1. Hold the end of the yarn close to the input
eyelet at the rear of the feeder.
2. Push the PTU activating button and
release the yarn.
3. Take hold of the yarn end.
5. Reset the feeder (switch off/on).
* = Full threading: Ensure that the yarn eyelet is
correctly positioned under the guide (A).

Rotating the spoolbody
With feeder connected to the weaving machine and
machine power on.
Switch off the feeder.
Press the button on the stopper housing and ensure
that the magnet pin retracts. The spool body can be
rotated as long as the button is activated.
With feeder removed from the weaving machine OR
when the power to the weaving machine is switched
off. Remove the two screws retaining the stopper
housing.
Remove the stopper housing completely. The spool
body can now be rotated as necessary.
WARNING!!
Failure to follow these instructions will result in damage to the spool body,
stopper magnet, stopper magnet pin or the stopper housing
When reassembling the stopper housing it will
be necessary to adjust the distance between the
magnet and the magnet finger (B) using the stopper
housing adjustment guide (A).
NOTE
Press the stopper housing towards the motor
ange while tightening the screws in order to
secure the correct distance between the stopper
housing and the magnet nger.
