Function / programming of the weave-in presser foot

Weft yarn presser foot

The weft yarn presser foot is activated / deactivated in the M1plus via the control column. This control column can be called up in the design pattern as well as in the Color Arrangement.

I. Use of the weft yarn presser foot:

The weft yarn presser foot is always active leading the knitting system

Weft yarn carrier - activated weft yarn presser foot - knitting yarn carrier in the following knitting system

The weft yarn presser foot is only active in the area, where the following knitting system is in action.

The weft yarn presser foot is activated before the first knitting needle and deactivated after the last knitting needle.
In the areas, where the weft yarn presser foot is activated and deactivated, no yarn carriers may be positioned.

Activating and deactivating the weft yarn presser foot:

The weft yarn presser foot is activated / deactivated independently of the carriage speed.

II. >How YDopt works:

Parking area for the yarn carriers that are knitting in the pattern row

: The yarn carriers are positioned staggered

Parking position (waiting area) for the momentarily non knitting yarn carriers

: The yarn carriers are positioned staggered

The yarn carriers are positioned staggered with a wide distance (parking position) in relation to the fabric selvedge.
The required yarn carriers are taken out of the parking position and start knitting.
While knitting, the active yarn carrier receives a new parking position and will be positioned much closer to the fabric selvedge.
The parking position is optimized (YDopt).
After the last knitting row, the active yarn carrier is returned to the parking position.
The following, knitting yarn carrier is taken out of the parking position and also positioned at the fabric selvedge with YDopt.

III. Yarn carrier parking positions at the fabric selvedge - YDopt and YD

Programming only with YDopt

The use of YDopt is mandatory (automatic staggering of the yarn carriers at the fabric selvedge) when programming with weft yarn presser feet. Here, the necessary parking positions of the yarn carriers in the corresponding technical rows are taken into account by the M1plus and entered in the Sintral.

A	Area with working weft yarn presser foot (weft yarn presser foot active)
B	Area for staggering the used yarn carriers with YDopt : In the Configuration / YD yarn carrier distance from the fabric selvedge dialog box under Optimized parking position, the number of used positions for YDopt can be influenced.
C	Area for activating / deactivating the weft yarn presser foot : This area always is the same, no matter if activating the weft yarn presser foot within or outside of the fabric.
D	YD default values for all the non knitting yarn carriers that are parked at the fabric selvedge. : YD values are specified in the Yarn Field Allocation dialog box.

Swiveled yarn carriers

The swiveled parked yarn carriers are positioned beside the first / last needle action outside the activation area of the weft yarn presser foot. The weft yarn presser foot does not collide with these yarn carriers.

F1	The area is plated with the yarn carrier 9A (light blue) and 7A (red)
F2	In this area the yarn carrier 9A (light blue) is redefined to a weft yarn carrier and the yarn carrier 7A (red) knits following. The weave-in device is activated. Weft yarn carrier 9A (light blue) - (weft yarn carrier cannot be swiveled) Knitting yarn carrier 7A (red)
1	Distance of the yarn carrier starting at the first knitting needle when activating the weave-in device - approx. 23 nic
2	Distance of the yarn carrier in the fabric starting at the last knitting needle when deactivating the weave-in device - approx. 35 nic

The same yarn carrier distances are used also with the same knitting situation at the fabric selvedge.
