THEORY OF OPERATION OF THE SECTION TRANSFER SYSTEM
3-1
Water circulation
A
circular
pump
delivers
distilled
or
demineralized water from a reservoir to a blade
carrier for high and low profile blades via a
tube.
Below the blade edge and the grid insert, the
delivered water is pressed through channels in
the direction of the blade edge.
Just in front of the blade edge, the water
injects into a cuvette-type groove. The water
flows down the transfer track and forms a
laminar stream.
On the lower end of the transfer track, the
water passes a flexible part of the transfer
surface, leading to the transfer bridge. This
flexible part serves for an even water flow at
different clearance angle settings.
When the transfer bridge is open, the water
together with debris flows into the intended
basket.
A closed transfer bridge connects the transfer
track with the water bath. High quality sections
reach the water bath without being damaged.
The water of the water bath is heated and used
for stretching single sections.
When the water level in the water bath has
reached a certain height, superfluous water
flows through the labyrinth spillway back into
the waste area. From here, the water flows
through several sieve inserts and finally
reaches the pump reservoir again.
