B.2.1 Operating principle and machine cycle
Operating principle:
The automatic single-head serging machine 1265-4 allows the automated
serging of inseams and side seams of trousers panels, with or without knee
lining. The sewing unit automatically sews and serges cleans the fabric con-
tour and incorporates the fullness for the knee lining, if required.
The trousers panels are sewn in separate machine cycles:
the inseam or side seam of the rear trousers panel,
the inseam or side seam of the front trousers panel with knee lining on
top,
the inseam or side seam of the front trousers panel with knee lining on
bottom.
NOTE - Applications
The machine has been designed predominantly for serging
trousers panels. However, it can also be used for processing
other sewing pieces, e.g. sleeves, short trousers, etc.
Machine cycle, Fig. 2:
The short seams can be serged manually at the sewing head

prior to
the sewing of the inseam or side seam.
The trousers panels are stocked on the upper tray

plate, the corresponding knee lining is aligned to
the trousers panel with the hems being flush.
At the optional bonding station

, the front and
rear trousers panels can be secured to each other
using a bonding mesh.
Both trousers panels are routed below the con-
tour guide

and lined up at the stop of the se-
wing head

cess. The fully automatic machine cycle is star-
ted.
During the sewing process, the contour guide

and the puller of the
transport unit

control the routing of the seam.
If required, the top and bottom transport units of the sewing unit incor-
porate fullness.
