The machine consists of the following components :

1. COMPLETE UNWINDING UNIT

1) Hydraulic reel lifting system.
2) No. 3 pneumatic reel-holding shafts.
3) Rotating reel holder table.
4) Inflation gun.
5) No. 3 automatic end-of-reel stopping devices.
6) Film towing system, with motorized cylinders and reduction gear, inverter
driven vectorial motor for controlling film unwinding.
7) System for micrometrical controlling of film tension by means of pneumatic
cylinders and pressure regulators. This system allows for optimizing the film
tension in compliance with the pre-set production parameters (thickness/bags/min.
bag dimensions).
8) Constant control of the film unwinding by means of a linear potentiometer for
detection of the dancing roll position.
9) System for ensuring easy film insertion.

2 COMPLETE WELDING MACHINE UNIT

1) Low inertia film compensation unit.
2) No. 1 photocell.
3) No. 1 Motorized compensator for adjusting the printing position
4) No. 1 servo-motor for towing film
    No. 1 servo-motor for bar movement
5) Antistatic, anti-shock bars
6) Additional container for stabilizing the pneumatic pressure
7) Air filtering unit with pressure regulator
8) Bulb for automatic pressure control
9) Patented bag stacking system with double press for formation of bundles of
bags in pre-set numbers depending on production requirements.
10) Patented mechanical bag tearer for production with elevated thicknesses
11) Automatic collection table with variable range, programmable in accordance
with the type of production to be carried out.
12) COMPLETE UNIT FOR BOTTOM WELDING :
- Bar-holder in special aluminium
- Upper welding bar made from cast iron profile
- Pair of resistors for heating the upper profile
- Temperature probe
- Rotating Teflon bracket
- Possibility of rotating the upper bar by 90° for inspection and maintenance
- Cutting system with toothed blade
- Lower bar-holder
- Lower profile made from special cast iron
- No. 1 resistor for heating lower profile
- Temperature probe
- Rotating Teflon bracket
- Digital thermoregulators for temperature control and setting.
13) CONTROL AND COMMAND PANEL :
- General computerization of data via digital PC
- Digital keyboard and color monitor for setting and checking production data
- Programming for bag count for bundles
- Programming bundle count
- Programming production speed
- Programming of welding time
- Programming of trolley positioner parameters
- "on the fly" adjustment of the most important production parameters without having to stop the machine to reset data
- Continuous visualization of production (bags/min.).
- Automatic self-learning system
- CHECK PANEL for identifying any faults
- Luminous column for identifying operating phases
- Warning buzzer for machine start-up
- Main switch : 63 a
Outlet: 3 x 380 + N + T or any other arrangement
- Electrical panel air-conditioning system
- Auxiliary socket for computer connection
- Pre-arrangement for future connection via modem with the manufacturer.

All the mechanical, pneumatic and electrical controls are grouped together on the side of the machine.

3. FOLDER AND BAG COLLECTING TABLE, complete with :

1) Trolley with pincers for extraction of bundles, controlled by the machine's microprocessor. The trolley is fitted with a last generation system which thanks to a two-speed control reduces the stopping times necessary for extracting the bundles.
2) Bag folding system with the possibility of carrying out up to 4 folding systems;
S" type folding system for avoiding the packaging between each bag welding; in this way the bags slip out one at a time, without having to open the bundle each time.
3) Semiautomatic table with variable range for producing bags with lengths exceeding 1500 mm.
4) No. 1 collection belt with intermittent translation controlled from the keyboard for collecting the finished bundles.
5) No .1 console fitted with emergency stop and belt translation controls.
6) Folder translation system that allows access inside the machine for maintenance operations.

4. Safety guards and emergency devices foreseen by the CE standards and the laws in force that govern the accident prevention regulations.
