Basic construction

The basic construction is a steel construction
and, on the whole, it is the housing (A) for the
following components:
• the compressing unit (see section 5.3),
• the channel adjustment (C),
• tie-off device (D) with cover,
• the electrical unit (E), with
• the stored program control - SPC - (F),
• the hydraulic unit (G),
• the funnel with (H) safety circuit.
The components cannot be shown completely
in the following illustration. However these will
be dealt with more thoroughly in the individual
sub-chapters 5.3 to 5.7.
5.3. Compressing unit with channel

adjustment

This assembly is responsible for the compaction
of the material filled in the charging opening.
The assembly mainly consists of the following
components:
Baling channel with press body (1),
Telescope sheets (2),
Polyamide guide rails (3) for the press body,
Polyamide guide rails (4) for the telescope
sheets,
Hydraulic cylinder (5), see hydraulic unit,
Channel adjustment sheets (6) with
tightening elements (7), and plate for bale
rest.
The press body is moved in the baling
channel by means of two hydraulic cylinders.
The movement of the press body is guided
by polyamide rails. Telescope sheets, which
protect the space behind the press body
against material falling into it, are pulled out
during the pressing movement.
Knives (9) are provided at the upper side of
the press body or the underside of the
channel entrance. At their cut edge the
knives cut the material filled in. They prevent
the pressure build-up on the upper side of
the press body and thus avoid excessive wear
at the polyamide guide rails.
