3.5.3 Lower feed wheel
3.5.3.1 Feeding clutches
3.5.3.1.1
Description
The feeding clutch is formed by the clutch cover (1) driven from the
connecting bar (2), by the clutch star (4) driven from the connecting
rod (3) and by the carrier plate (5) firmly connected with the shaft (6).
Of the clutch give the connecting rods (2 and 3) an opposite direction
swinging movement. The clutch is coupled by means of the wedge (7)
on the connecting rod (8) through the eccentric (9) which is placed on
the lower shaft (10).
In the position, when the wedge is disengaged, the star (4)
shifted out from the frictioning engagement with the lining of the carrier
plate (5) by means of the spring washer (11). The plate (5) lining is
then pushed by means of a flat profiled spring (12) against the cover of
the clutch (1).
In the position, when the wedge is disengaged, the star (4)
pushed against the plate (5) lining and, at the same time, the friction
connection with the cover of the clutch (1) is disconnected. Within a
short instant, when engaging and disengaging with the carrier plate
(5), there are in a friction engagement both the cover (1) and also the
star (4), namely in the dead centre of the connecting rods (2 and 3).
The setting of the change-over of clutches is done by tightening or by
loosening the nut (13).
