Folder (Cl.VEB100-5)
Setting the folder
To re-adjust the folder, the angle of inclination can be adapted to the fabric
thickness by means of knurled screw (1) (Fig. 13a and Fig. 14a). The folder
should be placed downwards until one fabric layer is nearly jammed between
the lower side of the folder and the plunger (Fig. 13).
The folder can be set horizontally after loosening screw (4) (Fig. 14a). 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. 15a) or under the hem edge (Fig. 15b).
Being the thread tension set correctly the overseam should be half as wide as
the hem (Fig. 15c).
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. 14a) is necessary. Then the shaft
has to be clamped again without any lateral play. If necessary, after releasing
three screws (3) (Fig. 14a) the complete bench with folder can be slightly
displaced on the needle plate.
