6 Operation of the machine
6.1 Production sequence
The Single-head Serging Unit 1225/4 achieves a full-automatic production
sequence together with a high production speed. The operator of the machi-
ne only has to:
• select the desired sewing program;
• fix front trouser and kneelining at the adhesion facility;
• insert the fabrics correctly;
• supervise the functionality of the machine.
The production sequence contains the following steps:
1. Fix front trouser and kneelining at the adhesion facility.
2. Lay fabrics on the working table and insert straightly below the contour
guiding of the sewing head.
3. As soon as the photo cell switches dark (and detects the inserted
trouser part), the sewing head starts sewing the trouser part. The
correct transportation is supervised by the photo cell, the speed of the
contour roll is adjusted if required. In this way, contours can be detec-
ted and serged correctly.
4. To ease the transportation of the cloth in the range of the sewing head,
table blowing can be enabled.
5. Towards the end of the sewing process, the movable blade will be
driven out to turn the trouser part for the sewing of the hip bow.
6. After serging the complete trouser part, the swing-out device trans-
ports it out of the machine where it will be stacked.
6.2 Program control
Hint
This machine is controlled with programs, which are stored in the memory
and can be selected by the operation personell. The editing of existing and
the programming of new sewing programs should be reserved to
experienced qualified staff. The possibilities are explained in the second part
of this manual.
6.2.1 Existing sewing programs
In the daily production process, the operating personell must only select one
of the pre-programmed sewing programs. The factory setting is:
