(6) [CF] Setting of the period of time during which the cloth presser foot stops

The cloth presser foot when delivering the belt loop presses belt loop and the fork
comes off after a certain time has passed. The period of this time can be set.
Standard set value is 0.00s.
If the dog ear is dissatisfied, set the period of this time longer so that the cloth presser
foot can securely press the belt loop.
However, the cycle time is extended as much as the set value.

(7) [CG] Setting of traveling backward distance of the fork at low speed at the time of set back

When performing the set back, the loop travels backward further from the place where
it comes in contact with the stopper plate.
This is the function to travel backward the fork at low speed to securely eliminate the
loop at this time.
This function does not work at set value "0". The function works with the input value
and the traveling backward distance is inputted.
The speed of traveling backward at this time is constant and cannot be changed.

(8) [CH] Setting of the length of time at the time of change-over of the supply slide base cam

Standard setting time is 0.08s.
Perform change-over of the supply cam up/down cylinder before this time in anticipation
of the time when the supply slide base travels backward to the end of its stroke.

(9) [CI] Setting of waiting time when the supply slide base travels backward to the end

Standard setting time is 0.03s.
Length of time to wait for calming down of damping of the jumping movement when
the folding shaft is changed over to up position by means of the change-over of cam.
If the shaft goes to clamp the belt loop before calming down of damping of the jumping
movement, the shaft may not be able to securely clamp the belt loop.
The setting time affects the cycle time when the belt loop is clamped at the first time,
and set back is performed.
When sewing is continuously performed, it takes time until the belt loop is drawn out
and this setting time does not affects the cycle time.
(Caution) When clamping mistake of the belt loop occurs even if the setting
time is extended, slippage of the height of fork is considered. Check
the installing dimension of the components.
