3. Vertical movements of the P.U.arm
Under the influence of the large long  CHUBBY tension spring (81) the lever tonge/ upper lifting strip (B
fig.8) is pulled in the >>>direction of the axis >>> of the control disc /command dial and rests against the
roller (123) on the cam disc. As When the control disc /command dial rotates, the roller rotates away
from the lever tab/ lifting strip, causing it to move >>>towards >>> the axis. As a result, the pick-up will
be pushed upwards by the lifting disc [82] . The movement/stroke is limited by the pin on the bottom
plate (73).
When at the  end of the revolution  of the control disc
When the roller 123 touches the lever plate/ lifting strip again, it is pushed back again, now in the
opposite direction against the force of the spring, and this gives the P.U, again the opportunity to fall
back descend, hereby helped by the pressure spring (85) under the pick up arm . The vertical
movements of the P.U.arm have now become clear. In order to prevent arbitrary/ random movements

PLATE (74) is also pulled towards the control disc/command dial. The roller (68) on the changer presses
against the cam disc.
When the control disk rotates, there is a moment when the wheel/roller follows the profiled portion
of the disk, causing the change device to move in the direction of the command disk axis and then be
