DA 20 – Packaging machine for small bags from 500 g to 1,5 kg,
for low production rates
Compact and economical: these are the peculiarities of the small packaging machine model DA 20.
- empty bag presentation;
- filling;
- vibration (to settle the product inside the bag);
- preparation of top edge of bag for downstream closure.
The closing system, located at the packaging carousel exit, is inline type.
The main movements are driven by mechanical cams, which guarantee:
- high precision,
- perfect synchronisation,
- minimal maintenance.
Side hatches ensure excellent access and compliance with the most restrictive safety regulations.
Compact and economical
For preformed bags from 500 g to 1,5 kg
(Bag weight refers to packs of products having specific weight from 0.5 to 0.8 kg/dm3. Different specific weights will affect the bag’s weight)

Sealed
Stitched
Glued
FLAT-TOP (BRICK)
APPLICATIONS
The range of options and equipments available meets the most varied applications and needs:
- dosing or weighing
- electronic weight checking with automatic feedback to the dosing system, rejection of the out-of-tolerance bag and weight logging;
- closure using glue, stitching or welding;
- labelling;
- bundling and heat-shrinking;
- online process monitoring and telephone support.
GENERAL CHARACTERISTICS
MAIN DRIVE UNIT
- mechanical cam type;
- grease-lubricated.
BAG MAGAZINE
- quick and easy to adjust;
- convenient to refill;
- 300/350 bags capacity per magazine;
- empty magazine alarm;
- can be refilled without having to stop the machine.
4-STATION CAROUSEL
- operated by mechanical cams;
- die-cast aluminium head, completely enclosed to guarantee hygiene and prevent dust from reaching the mechanisms (1);
- bag presence sensor (no bag - no filling);
- top edge of the bag supported by suction cups connected to the vacuum pump (2);
- dust extraction hoods (2);
- vibration table (2).
Bags rest on a vibrating table.
The vibration stroke can be adjusted to meet different needs.
HOT-MELT GLUE CLOSURE
The filled, vibrated bags are conveyed step-by-step in a straight line through the glue closing station, where the following actions are performed in sequence:
- trimming of the top edge (3);
- double folding of the edge (3);
- application of hot-melt glue by a rotary disc distributor (4);
as an alternative, for special requirements and applications, a spray module for hot-melt glue application is installed; - pressing of the sides (and top for flat-top closure) to create a compact, properly squared bag (5).
WELDED CLOSURE
As an alternative to glue closure, welding can be used (on bags in weldable material).
Bags are conveyed, step-by-step, to the welding station, before which the top edge of the bag is trimmed.
The welder, with heated bars controlled by thermostat or with on-off operation, is pneumatically operated.
Welding temperature and time are fully adjustable parameters.
STITCHED CLOSURE
After packaging, bags are evacuated from the carousel for closure by stitching. The packaging machine is combined with the model LCS stitching system and is available in the following versions:
- SC: SC: single seam;
- CR: seam with fold;
- CC: seam with crepe paper.
CONTROL BOARD
The push-button control board is structured to ensure user-friendly operation of the packaging line.
An operator interface is also provided to allow access to the machine settings and alarm messages.
ELECTRICAL PANEL
The electrical panel is integrated on board the machine, completely wired, and easily accessible.
The operational control is with PLC logic.
The standard degree of protection is IP 54.
DOSING – WEIGHING
VERTICAL SCREW DOSER FOR POWDERS
- container in AISI 304 stainless steel;
- motor-driven internal agitator;
- speed control system with encoder;
- speed control with frequency changer (inverter);
- pneumatically operated shut-off gates;
- dust extraction intake at discharge outlet;
- rapid change for the dosing screw (quick coupling).
SWINGING CUP DOSER FOR GRANULAR PRODUCTS
- 2 cups in AISI 304 stainless steel;
- cup volume adjustment with electric remote control (motor + encoder);
- discharge hatches with return spring;
- swinging motion powered by a motor driven by inverter for a perfect synchronisation according to the packaging speed;
- single discharge channel in AISI 304 stainless steel;
- dust extraction intakes.
INLINE WEIGHING UNITS
For applications where weighing is required (powder detergents, tea, biscuits, short pasta, etc.) the packaging machine can be combined with one or more net weight inline weighing units, NE model.
BUNDLING
BUNDLER F/70 MODEL
The bundler groups bags into bundles and wraps them with shrink-wrap film.
Suitable for bundles of sizes:
| Min. | 160 x 160 x 90 (h) mm |
| Max. | 450 x 350 x 300 (h) mm |
It is equipped with:
- pneumatic pushers for bundle formation;
- bag flow monitoring system with photocells;
- support for the 2 reels of wrapping film;
- thermostat-controlled welder and cutting blade for the wrapping film;
- perimeter guards.
It is available in single input version (6 and 7).
Bundling programs are always custom-created and can manage one or more sizes, selected with just a switch.
Control board
HEAT-SHRINKING
HEAT-SHRINKING OVEN F/70 MODEL
After wrapping with film, the bundle undergoes heat-shrinking in the oven.
The metal mesh conveyor (with adjustable speed) carries the bundles through the heat-shrinking chamber, which is heated by electrical elements and has forced-air ventilation.
The chamber is insulated with rock wool.
Bundles leaving the oven are cooled by an electric fan and conveyed on a parking roller conveyor.

Estimated size change time:
1.5 hours approx.
DA 20 SIZE CHANGE
1.5 h approx.
SIFTER (FOR FLOUR SAFETY)
