Function / programming of the weave-in presser foot

纬纱压脚

在M1plus里通过控制列来激活/禁用纬纱压脚。这个控制列可以在设计花型以及颜色排列里调用。

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.

激活和禁用纬纱压脚：

纬纱压脚的激活/禁用是独立于机头速度的。

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

只用YDopt编制程序

在编制使用衬纬装置的程序时，必须使用YDopt（布边自动交错排列导纱器）。在这里，M1plus会考量相应的工艺行中的导纱器的必要停止位置，并输入到Sintral里。

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.

Yarn carrier distances a the fabric selvedge (outside shape):

摆动导纱器

摆动的停位导纱器被置于衬纬装置禁用区域外侧，在第一枚/最后一枚织针动作区域之外。衬纬装置与这种导纱器没有冲突。

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
