SFOINIT

The SFOINIT tab contains the settings for the initialization of the feed wheels. The settings from the SFOINIT tab is effective as long as no SFOI entry is assigned via the control column.

Every created group receives an entry in the SFOINIT tab that can be edited specifically for the group.

If no values were entered for a group, then the values from the group 0 are effective.

Groupe

Déterminer le groupe fournisseur pour les paramètres communs.

Quantity of feed wheel groups:
1 – 6 (serial, connected using EFS kit (ID 268 338))
1-100 (CAN, connected using CAN-Gateway)

Group 0
Basic setting, if no values were entered for a group.

If no basic setting was defined for a feed wheel group, the values of the "Group 0" will be effective.
(Default: 4.0 cN for all tensions and 8 windings)

Tip: If only one feed wheel group is used in a knitting program, you can work with the "Group 0". This has the advantage that you do not need to adjust anything in the "SFOI" tab.

Travailler [cN]

Valeur de la tension du fil en cN pendant que le fil est tricoté.

No yarn is taken-up in the carriage reversal.

Value range:
EFS: 0.5 cN - 40 cN
ULTRAFEED: 0.2 – 99.5 cN

Réduction [cN]

Valeur de la tension réduite du fil en cN quand il n'est pas tricoté de fil.

Normally, the reduced yarn tension is about 0.4 cN higher than the knitting or the reciprocation tension.

Value range:
EFS: 0.5 cN - 40 cN
ULTRAFEED: 0.2 – 99.5 cN

Oscillation [cN]

Valeur de la tension alternée en cN

The yarn tension is maintained constant:

when moving the yarn carrier back and forth and also during a yarn carrier run with overrun path
during the carriage reversal

Value range:
EFS: 0.5 cN - 40 cN
ULTRAFEED: 0.2 – 99.5 cN

Type de fonctionnement

Sélectionner le type de fonctionnement avec la tension du fil définie pour cela.

Tension d'abaissement du fil
Oscillation
Tension de travail du fil

Tension d'abaissement du fil
Only the value from the Réduction [cN] column is used.

When the machine stops (engaging rod down), the reduced yarn tension is active.

Normally, the reduced yarn tension is about 0.4 cN higher than the knitting or the reciprocation tension.
When the machine starts, a small yarn loop results - the yarn tension is reduced. To compensate this, the reduced yarn tension will be increased somewhat.

At the feed wheel, the "Réduction" symbol is only displayed if the reduced and the working yarn tension have different values.

Oscillation
The values from the Oscillation [cN] and Réduction [cN] columns are used.

The operating mode "Oscillation" was developed specifically for the flat knitting machine.

The yarn tension is maintained constant:

when moving the yarn carrier back and forth and also during a yarn carrier run with overrun path
during the carriage reversal

In the carriage reversal, the yarn length that is not needed will be restored by the feed wheel.
Yarn tensioning path: max. 600 mm (EFS 820: 200 mm)

You can adjust the reciprocation tension in the "Mode 8 / Rec %" column.

Special case: Elastic yarns (e.g. Lycra)
If the yarn breaks in the carriage reversal, select the "Travailler" operating mode.

Tension de travail du fil
The values from the Travailler [cN] and Réduction [cN] columns are used.

During the production (engaging rod up) the feed wheel regulates the yarn tension.
No yarn is taken-up in the carriage reversal.

Enroulements

Déterminer le nombre d'enroulements autour de la roue d'entraînement du fil.

Value range 1 – 40
Default 8

The number of yarn windings are entered directly on the feed wheel (Mode 61).
When threading-up the feed wheel, the yarn is wound around the yarn wheel as many times as you specified.

If you want to change the number of windings, enter it directly on the feed wheel (Mode 61). Then, thread-up the feed wheel again.

REC%

Déterminer en % la correction du retour de la tension du fil lors du rappel du fil.

Only active with the "Oscillation" operating mode.

Value range:
EFS: 0 - 200 %
ULTRAFEED: 20 – 150 %

Default 111 %

Increase the value with a heavy yarn to compensate the inertia of the yarn.

With a fine, sensitive yarn reduce the value so that the yarn does not break when accelerating.

Not available for MEMMINGER-IRO sériel.

Adjust the yarn tension return correction:

with CAN connection using the Setup menu on the knitting machine
(Do not set the value on the feed wheel, as the setup menu on the knitting machine would overwrite this value.)
With serial connection:
EFS: At the feed wheel call up the "Set up -> Mode 8" menu.
ULTRAFEED: Serial connection not possible, only CAN connection possible.

PREC

Déterminer la fonction de rappel permanente.

The take-up function prevents yarns from sagging after a machine stop.

Value range 0 - 1
Default 0

0 = The feed wheel works with the specified operating mode (Travailler, Réduction, Oscillation).

1 = The feed wheel always works with the "Oscillation" operating mode.

With a machine stop the feed wheel changes to the "Réduction" operating mode by default.

If one is working on the machine, threads can be pulled by mistake - the yarn will be sagging. If the machine is started then, it can lead to an error.

Remedy: Activate the take-up function ("1").
Disadvantage: The feed wheel always works in the "Oscillation" operating mode and may get hot.

Adjust the take-up function:

with CAN connection using the Setup menu on the knitting machine
(Do not set the value on the feed wheel, as the setup menu on the knitting machine would overwrite this value.)
With serial connection:
EFS: At the feed wheel call up the "Set up -> Mode 12" menu.
ULTRAFEED: Serial connection not possible, only CAN connection possible.
