SFOINIT

组

设定一个具有相同设置的送纱器组

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.

This row contains pattern-related values that are displayed below it. By clicking on the icon, the pattern-related values are hidden.

This row is a pattern-related row.

In the context menu of a selected row you can insert a row for pattern-related values of a specific pattern.

新花型

Name of the pattern in case of rows with pattern-related values

工作 [cN]

纱线参与编织时的纱线张力。单位cN

No yarn is taken-up in the carriage reversal.

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

减少 [cN]

纱线不参与编织时的减小的纱线张力。

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

往复卷取 [cN]

回卷张力值，单位 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

操作模式

选择特定纱线张力的操作模式

• 张力减少
• 往复卷取
• 工作张力

张力减少
Only the value from the 减少 [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 "减少" symbol is only displayed if the reduced and the working yarn tension have different values.

往复卷取
The values from the 往复卷取 [cN] and 减少 [cN] columns are used.

The operating mode "往复卷取" 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 "工作" operating mode.

工作张力
The values from the 工作 [cN] and 减少 [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.

卷绕

设置卷绕在送纱器上的圈数。

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%

设定纱线回储过程中的纱线张力修正 %。

Only active with the "往复卷取" 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 串行的 MEMMINGER-IRO.

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

设置持续回储功能。

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 (工作, 减少, 往复卷取).

1 = The feed wheel always works with the "往复卷取" operating mode.

With a machine stop the feed wheel changes to the "减少" 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 "往复卷取" 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.
