8. ADJUSTING THE MECHANISM OF OPENING OF UPPER THREAD
Opening of plates
(
3)
of main tensioner is actuated by pneumatic valve
(1
)
which is
connected with rod
(
2), Fig.
31
.
This valce is controlled by parameter 16. This parameter
indicates the position of the needle when the plate is opened. These plates are opened at
last trimming movement. It ensures sufficient length of upper thread after trimming so
that the first stitch
with next sewing operation is done properly and there is no risk of
removal of the thread.
Correct movement and size of opening of plates is set by position of rod
(
2)
when the
control pin of main tensioner
(
4), Fig.
32 is in touch of stagnation area of rod
(
2). We are
oriented by distance from the edge
(6
)
of stagnation area
(
5)
with adjustment of point of
touch of pin
(
4). This point of touch afects the size of opening of plates.
Set the value in 0.6mm for general materials and 0.8
-
1mm for heavy materia
ls.
It is done by loosing
nut (
7)
and turning of piston rod of pneumatic cylinder. Finally
tighten the nut
(
