SFOI

For different knitting situations, due to the SFOIentries, it is possible to make different settings for a feed wheel group.

Nome

Nome do índice de alimentador

Grupo

Estabelecer grupo de alimentadores para configurações em conjunto.

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.

Trabalhar [cN]


Valor da tensão do fio em cN enquanto o fio é tecido.

No yarn is taken-up in the carriage reversal.

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

Reduzir [cN]


Valor da tensão do fio reduzida em cN enquanto nenhum fio é tecido.

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

Oscilar [cN]


Valor para a tensão de oscilação em 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

Modo de operação

Selecionar modo de operação com a tensão de fio estabelecida para ele.

  • Tensão reduzida do fio
  • Oscilar
  • Tensão do fio de trabalho

Tensão reduzida do fio
Only the value from the Reduzir [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 "Reduzir" symbol is only displayed if the reduced and the working yarn tension have different values.

Oscilar
The values from the Oscilar [cN] and Reduzir [cN] columns are used.

The operating mode "Oscilar" 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 "Trabalhar" operating mode.

Tensão do fio de trabalho
The values from the Trabalhar [cN] and Reduzir [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.

REC%

Estabelecer correção de recolhimento em % para a tensão de fio no processo de recolhimento.

Only active with the "Oscilar" 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 Serial 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.
