7.10. Adjustment of hopper track, fixed track and track
In order for the hopper track to scoop up screws out of the basket and
feed them onto the track smoothly, it is necessary to position the
hopper track, fixed track and track properly.
(1) Relation between top dead center of hopper track and height of
track
A proper relation between the top dead center of the hopper
track and the height of the track is shown in Fig. 28; an improper
relation between them is shown in Fig. 9 and Fig. 10. In the
latter case, loosen screw C shown in Fig. 27 and adjust the top
dead center of the hopper track properly.
