2.16 Functions and operation of the optional equipment
In this chapter the function and the operation of the most important
optional equipment is described.
2.16.1 Automatic incision device for piping ends
With the automatic incision device for piping ends the piping strip end
is cut open from the center knife incision to the piping ends. The
cutting areas are automatically adapted to the respective seam length
as well as to the positioning point.
The piping strip ends can be notched up to 30 mm (with a pocket
length of 180 mm) or 20 mm (with a pocket length of 200 mm). The
incision device for piping ends is already a component of the
E-equipments E 3503, E 3504, E 3507 and E 3508.
The total length L of a piping incision always amounts to
approx. 45-50 mm (dependent on the fabric) and cannot be altered.
The programmable value S indicates the length of the cut within the
pocket length T.ThevalueS is set to 15 mm as a standard. With this
adjustment the piping strip is notched 30 mm from the seam. When
increasing the value S the c ut is shifted to the middle of the pocket;
when the value S is reduced, the cut is shifted outwards (see sketch on
page 67).
Note
At the front or the rear positioning point with sewing lengths of 200 mm
the cutting length can only be altered inwards to the middle of the
pocket.
Activating and sw itching the piping incision device on
–
Select the parameter “Piping incision device” and the icon “Piping
incision device on/off” under the menu item “Pocket parameters”
(key F1) - see Programming Instructions, chapter 5.4.
Correcting the position of the cut
–
Select the parameters “Piping incision device on/off -
Correcting the piping incision at the seam beginning” or
“Piping incision device on/off - Correcting the piping incision
at the seam end” under the menu item “Pocket parameters” (key
F1)
(See Programming Instructions, chapter 6.4)
The entered correcting value corresponds to the value S.
