The machine’s work zone (zone Z fig. 2.3.1) is composed of sub-zones and specifically (Z =
ZA+ZB+ZC+ZD+ZE):
1. Spool holder shaft, and film unwinding rollers (zone ZA fig. 2.3.1).
2. Product infeed conveyor (zone ZB fig. 2.3.1).
3. Longitudinal sealing group (zone ZC fig. 2.3.1).
4. Transversal seal/cut group (zone ZD fig. 2.3.1).

DANGER
Some of the sub-zones of the machine’s work zone are dangerous and it is
prohibited to enter these zones when the machine is running or on standby while
awaiting commands.
The machine executes the packaging cycle in a totally automatic manner. The operator
loads the product to be packaged onto the infeed conveyor (zone ZB) only on machines that
are not equipped with the automatic load system; this operation must be done in safe
conditions since the load zone of the infeed conveyor may be hazardous. The operator is
allowed to enter the other dangerous work sub-zones (ZC-ZD-ZE-ZF) only under safety
conditions, that is, with the machine at a standstill and when there is no possibility of the
machine getting started suddenly without the operator being informed.
Entering the machine is allowed only for the following operations:
Preparations (with the machine at a standstill or in active IMPULSE mode);
Loading of product on the infeed conveyor (with machine running);
cleaning (only with machine at a standstill and power feeds cut off);
maintenance (only with machine at a standstill and power feeds cut off).
