Activating and Deactivating the Weft Yarn Presser Foot

Rail allocation for the use of weft yarn presser foot

: Recommendation:
We recommend to use the inner yarn carrier tracks for the weft yarn carriers with patterns having weft yarn and weft yarn presser feet.

Recommendations for the different types of machines:

ADF 530-32 W
ADF 530-32 BW

Tracks 7 - 10

ADF 530-24 W
ADF 830-24 W

Tracks 6 - 7

ADF 530-16 W
ADF 530-16 BW

Tracks 4 - 5

: Due to the different angles of the yarn carrier bows it is necessary to keep larger parking distances.

Distances for activating and deactivating the weft yarn presser foot without using a weft yarn carrier

  • Pressa W control column:

1

Select the type of weft yarn presser foot

2

Select the type (e.g. Type 2) of weft yarn presser foot

  • Auto :
    Automatic selection the type 2 weft yarn presser foot for at front and rear
  • Davanti :
    Using weft yarn presser foot type 2 at front
  • Dietro :
    Using weft yarn presser foot type 2 at rear

  • Without using a weft yarn carrier

Positioning the yarn carrier 7R (yellow) in order to use the weft yarn presser foot in the following knitting row

1

Distance of the yarn carrier from fabric selvedge when activating the weft yarn presser foot - approx. 22 nic

2

Distance of the yarn carrier from fabric selvedge when deactivating the weft yarn presser foot - approx. 23 nic

: The needle selection via the 'Split' cam curve starts earlier regarding the needle selection via the 'Stitch' cam curve.

 

  • No yarn carrier may be parking in this area.
  • At the fabric selvedge and within the fabric, the weft yarn carrier is parked at first before all the other knitting yarn carriers are staggered.
    : The yarn carrier staggering is done by YDopt.
  • If activating the weft yarn presser foot is necessary in the following knitting row, this will be included when parking the weft yarn carrier.

For the combination of inverse plating with active weft yarn presser foot, ESCI 50 with a default value is automatically assigned to the trailing yarn carrier when changing the plating colors between the systems.
