3.5.2.2
Setting of the vertical component
of the feeder movement
The lifting eccentric (1) must be angularly set in such a way,
so that the vertical movement of the feeder is delayed on
phase against the movement of the needle. This requirement
is fulfilled by the angle 354
°
on the handwheel (2) for the
stitching categories 100 and 200, 348
°
suits for the stitching
categories 300 and 400, when the setting bar (3) is inserted
into the eccentric (1) and is propped against the shaft (4).
Caution! Danger of injury!
Switch off the main switch! Before starting the
setting operation, wait until the motor stops!
- Set the value 354
°
(348
°
) on the handwheel (2) and fix it
with the screw (5), which is a component part of the machine
accessory (tighten it with care).
- Loosen the screws (6) of the eccentric (1).
- Insert the setting bar (3) into the slot of the eccentric (1)
and prop it against the shaft (4).
- Tighten the screws (6).
3.5.2.3
Setting of the feeder position against
the throat plate
The correct position of the feeder is such when the feeder
symmetrically moves in the slot of the throat plate in forward
and backward direction and above and below the throat plate
as well.
Caution! Danger of injury!
Switch off the main switch! Before starting the
setting operation, wait until the motor stops!
-
Using the handwheel , set the needle into its top dead centre
(the feeder is in its maximum position above the throat plate).
- Loosen the screw (1) of the gripping joint of the lever (2)
(this will separate the feeder from the source of the horizontal
component of the feeder movement).
- In moving the feeder (3) in forward or backward direction,
set the middle position of the feeder in the slot of the throat
plate.
- Tighten the screw (1), check the movement of the feeder
with the maximum stitch length (the gap in the throat plate
slot must be the same before and behind the feeder)
- After having loosened the screw (4) of the lever (5), in turning
the eccentrric (6), we can change the height of the feeder
above the throat plate (this has been set up on the
manufacturing factory, it is being used in practice with the
flatbed sewing machines)
- After having loosened the screw (7) of the lever (8), inturning
the eccentric (9), we can change the longitudinal inclination
of the feeder with regard to the throat plate /the optimum
position has been set up in the manufacturing factory the
cutting of the of the eccentric (9) is situated at the spot of
the cutting of the gripping joint of the lever (8)/.
