7.1.2 Overview – Twin Head in D-Series
As the name implies, 2 identical placement heads have been combined to form a single unit. The TWIN
Head in the form of these 2 segments is mounted on the D3 machine.

7.1.3 TWIN Head Vacuum Generator
7-1: Vacuum generator
The vacuum generator automatically controls the
vacuum, air blast and the zero balancing position
(middle position-->no vacuum and no air blast) for
the segments, with the aid of an iron core and
inductor.
Legend
1. Compressed air input
2. Exhaust to the silencer and cooling for the X-
linear motor
3. Output vacuum - vacuum is passed through
the D-axis motor shaft and then to the nozzle.
7-2: Principle of the vacuum generator
Legend
1. Compressed air input
2. Venturi nozzle
3. Plunger (iron core)
4. Plunger drive (inductor)
5. Exhaust to silencer
6. Vacuum air blast output
7-3: Filter for the vacuum system (TWIN segment version 03 shown as
example)
Legend
1. Filter for the vacuum system on the TWIN
Head.
The filter is mounted on the return unit and used as
an attenuator to control the vacuum. The filter, with
the relevant volume of metal hose, reduces
oscillation of the vacuum generator and
guaranteed an accurate vacuum and air blast
supply. The filter is serviced at regular intervals,
which must be adhered to (see maintenance
guide).
