General
1.5 General
The ZSK Automatic bobbin winder is suitable to fi ll automatically empty bobbins
with corresponding yarns. It is conceived in a way that both small cones and
big cones can be used to fi ll the bobbins. Bobbins in different sizes can be fi lled
(Filling only one bobbin size each time - no mixed fi lling of different sized
bobbins!)
The handling of the bobbin winder is easy and does not call for any special
training.
It has to be guaranteed that the automatic bobbin winder is con-
nected to a corresponding power supply (see type label on the
rear side).
Before connecting it to the wall socket, the rocker switch (rear
side) has to be in position ‘O’ (OFF).

Winding process
1.9 Winding process
1.9.1 Start winding process
• Charge the bobbin depot with empty
bobbins.
Removing of bobbin depot cover is to be performed only if the
plug has been removed from the mains socket. Operation is allo-
wed only when covers are mounted and closed.
• Switch on the rocker switch on the rear side, position ‚I‘.
Handle with care operation push button JOGGING. This is a
setting mode with winding, cutting and clamp mechanisms which
perform movements also when the cover is opened. Ensure when
using this mode that no clothes, hair, rings, chains etc. plus
extremities are not close to moving parts. There exist the risk of
cutting damage and contused wound, as well as burn, abrasion
and catching through rotating parts.

02418V10 • 11.08.2016/DC • 1-15
Winding process
• Press repeated the switch JOGGING,
until the bobbin support is completely
released.
• Control the thread excess lenght
underneath the needle. If necessary,
pull down the thread through the
needle using a forcepts.
• Press repeated the switch JOGGING, until an empty bobbin is located in the
bobbin support, the bobbin support is closed and the thread is trapped between
bobbin and rubber cushion.
• Control clamping of the thread (see image enlargement).

Winding process
• Press the switch JOGGING, until the
empty bobbin starts fi lling.
• Close the winder cover.
• Operate the dip-switch on front side in
position ON.
Check once in a while the charging level of the bobbin depot
during the automatic winding process. Fill the depot with more
empty bobbins if needed.
The automatic winding process begins. The thread will be cut after fi lling the fi rst
bobbin, another bobbin will be loaded and fi lled.
This process is continued until it will be interrupted.
• Operate the dip-switch on front side in position OFF.

Adjustments
1.10 Adjustments
1.10.1 Adjust thread tension
The thread tension will be adjusted with the knurled ring of the rear and front
tension regulator
Clockwise rotation  Thread tension is increased
Counter clockwise rotation  Thread tension is decreased
The thread tension has to adjusted with both knurled rings, so
that the bobbins will be fi lled not to tight and that after thread
cutting the thread breakage sensor not interrupted the winding
process.
The correct thread tension at the bobbin case is shown in the fi gures below:
Rear tension regulator
Thread brackage sensor
Front tension regulator
Retracting bow

Adjustments
1.10.2 Thread breakage sensor
The thread breackage sensor is used for monitoring and interruption the winding
process at thread breakage or an empty yarn cone. By reduction of thread tension
through occasions outlined above the thread breakage sensor gets loose, moves up
and interrupt the winding process.
1.10.3 Retracting bowl
The retracting bow hold the thread during the winding process in a position,
which warranted, that the bobbin thread moves preferably vertical from above
into the bobbin support.
After thread cutting the bobbin thread is slightly retired at the cutter from the
retracting bow, that means, for the next winding process the lenght of sagging
bobbin thread will be slighly reduced, so that no overlaying thread (thread
beginning) is formed when winding the next bobbin.

Adjustments
1.10.4 Adjust cut-off time
The cut-off time of the bobbin fi lling is adjustable (e.g. if small bobbins are not
fi lled properly or after backfi tting the winder towards bobbins with a greater
diameter).
• Pull via JOGGING automatically a new bobbin into the bobbin support, for
which applies the adjustment.
• Start winding process.
• Adjust the new cut-off time through counter clockwise respectively clockwise
rotation of the regulating screw. In the process the spring will be lowered
or uplifted and the cut-off time will be modifi ed.
Regulating screw clockwise rotation  cut-off time earlier  lower charging level
Regulating screw counter clockwise rotation  cut-off time later  higher charging level
The cut-off time has been chosen correctly, when the bobbin is
reeled up to its brim. Avoid extremely fi lled or brimmed over
bobbins.

Troubleshooting
1.11 Troubleshooting
Fault Cause Remedy
Bobbins have been fi lled
irregularly (one-sided).
Direction of the thread shake
down in the bobbin is one-sided.
Check left-right-justifi cation of
yarn guide. The position of yarn
guide has to be verical over the
bobbin support.
Empty bobbins will not be
delivered to the bobbin support
during the winding process.
Buzzer sounds.
1. Bobbins are clamped in the
bobbin depot and did not
slight into the lower guidance
groove.
2. Empty bobbin depot.
1. Put a pin in the borehole
of bobbin depot and rotate
