5.6.2 Sewing with folder
Folder (Cl.VEB100-5)
The machine is equipped with a special combination of stitch plate and folder to
provide side and back parts of sack coats with a uniform book seam.
Folders with a width of 6, 8 and 10 mm (finished hem width after pressing) are
available.
The standard machine is equipped with folder 286.0364, size 6x1 for thin to medium
material.
Roll hemmer (Cl. VEB100-4)
The stitch plate is equipped with a special material guide (roll hemmer) that "rolls in"
the sewing material at the edge during the running into the stitch plate.
The roll hemmers No. 0, 1, 2, roll diameter are available for thin medium, thick
material and and the Special roll hemmer for sewing curves.
Serially, the standard roll hemmer 286.0428, size 1, has been mounted and set for
medium sewing material.
5.6.2.1 Setting the folder
Folder (Cl.VEB100-5)
To re-adjust the folder, the angle of inclination can be adapted to the fabric thickness
by means of knurled screw (1) (Fig. 14a and Fig. 15a). The folder should be placed
downwards until one fabric layer is nearly jammed between the lower side of the
folder and the plunger (Fig. 14).
The folder can be set horizontally after loosening screw (4) (Fig. 15a). This adjustment
becomes necessary when a folder is replaced by another one or if the seam
appearance has to be modified.
According to the adjustment the seam can either be placed on the hem edge (Fig. 16a)
or under the hem edge (Fig. 16b).
Being the thread tension set correctly the overseam should be half as wide as the hem
(Fig. 16c).
After re-adjustment of the horizontal folder setting the inclination angle of the folder
has also to be re-adjusted as described above.
If a fine adjustment by means of the knurled screw is not possible any more, a coarse
setting after loosening screw (2) (Fig. 15a) is necessary. Then the shaft has to be
clamped again without any lateral play. If necessary, after releasing three screws (3)
(Fig. 15a) the complete bench with folder can be slightly displaced on the stitch plate.
