3.1.6 Setting the folder
Roll hemmer(Cl.VEB100-4)
Using the knurled screw (4) (Fig. 1 and Fig. 4), the tilt angle of the roll hemmer towards
the plunger can be set.
This influences the seam diagram (zigzag stitch). The needle can pierce the roll more or
less deeply.
This setting is the most important control together with the stitch depth regulation
during roll seaming.
The horizontal setting is done after loosening the screw (1) (Fig. 5). This is necessary
when the hemmer is exchanged for a different one, or if the seam diagram should be
changed.
If the horizontal setting of the hemmer was changed, the hemmer tilt angle needs to
be corrected again afterwards as described above.
If the range for the knurled screw is exhausted, then the rough setting can be redone
after loosening the screw (5) (Fig. 1 and Fig. 4). Afterwards, the axle needs to be
clamped again without lateral play. If necessary, the entire bearing block with hemmer
can be slightly adjusted on the stitch plate after loosening the 3 screws 1x (4) and 2x
(2) (Fig. 5).
Folder (Cl.VEB100-5)
To readjust the folder, the angle of inclination can be adapted to the corresponding
fabric thickness by means of knurled screw (5)
(Fig. 5) . Put the folder down until one fabric layer is nearly “jammed“ between folder
and presser (Fig. 1) .
Realize the horizontal adjustment after removing screw (1) (Fig. 5) . This is necessary
when the folder is replaced by another one or if another seam appearance is required.
If the horizontal folder setting has been modified, the angle of inclination of the folder
has to be readjusted as described.
If a fine adjustment by means of the knurled screw is not possible any more, remove
screw
(3) (Fig. 5)
and realize a new coarse adjustment. Then clamp the shaft again
without any lateral play. If necessary, also the whole bearing block with folder can be
slightly displaced on the stitch plate after removing screws (4) and (2) (Fig. 5) .
