The LSK ERGON series is composed of automatic shrink wrap machines to pack plastic, metal, cardboard or glass containers. Depending on the model chosen, they can make packs in film only, cardboard pad + film, cardboard tray, cardboard tray + film.
LSK ERGON series packers achieve an output rate up to 40 packs per minute in single lane (40+40 in double lane), according to the machine model and the type of product to be handled. The pack collations can vary according to the containers shape, capacity and size; the most requested collations are: 2x2, 3x2, 4x3 and 6x4.
All LSK ERGON machines are equipped with a mechanical product grouping system and are supplied with an in-line or a 90° infeed conveyour, depending on the customer’s exigencies. The change-over is manual.

1In the machine infeed zone, an oscillating unscrambler accurately lines up the loose containers carried by a conveyour belt featuring low-friction chains made of thermoplastic material. In the pack formation zone, the containers are clustered in the required format through a pneumatic device operating in alternate motion.
2In P and T models, a corrugated cardboard pad or blank is picked from the blanks magazine by an alternate motion picker composed of a group of vacuum suckers. The pad or the blank moves along the blank climb and gently places itself underneath the group of products in transit with the long side leading.
3In the trayformer, special mechanical devices fold the blank’s front and rear flaps. The side flaps are sprayed with hot melt glue and then folded, thus forming the tray.
4The unwinding of the film reel, placed in the lower part of the machine, is controlled by a progressive brake, which ensures the film constant tension. Before the pack enters the shrinking tunnel, the film is wrapped around the container batch and overlapped at the base of the pack.

The shrink tunnel features state-of-the-art technical solutions reducing energy consumption and ensuring an eco-friendly working process.
The tunnel conveyor belt is made up of fibreglass bars, driven by side chains (®SMI).
Thanks to the precise analysis of thermodynamic phenomena generated by the shrink process, the tunnel distributes hot air flows in an efficient and homogeneous way on the pack, thus ensuring its excellent quality at the end of the process.
Shrink resistances are positioned on the side walls of the tunnel
Heat-shrinking tunnel with forced air ventilation
POSYC® control panel mounted man-high and running the whole length of the machine (fixed on LSK ERGON models)
Power supply: from 380 to 480V (±5% max.) 50/60 Hz 3PH + PE
Power supply equal to 230 or 575V: with autotransformer
Reduced size and competitive prices
Thanks to their reduced size, the LSK ERGON machines are the ideal solution for the customers who do not possess large plants. Moreover, the price of the LSK ERGON models is very competitive, despite the high-tech solutions and the use of very reliable components. All LSK ERGON models can be customized, in order to increase their basic functions.
SMI machines are designed according to advanced principles of module assembly and feature interchangeable mechanical and electronic components, which ensure a reduction of the down-times during technical interventions or programmed maintenance and the optimization of the use of spare parts on stock.
SMI machines can package a wide range of products in several pack collations, so as to effectively meet the end user's current and future requirements.
Moreover, each machine can be equipped with additional devices, which increase its basic functions and ensure a high level of customization of the final package.
Motors directly connected to the drive shafts
SMI machines do not include gearboxes: the motors are directly connected to the drive shafts. The consequent advantage is the reduction of maintenance, energy consumption and noise.
SMI machines are pre-arranged to control up to three different machine pitches, without replacing the mechanical components. Therefore, it has been possible to increase the product dimensions range of almost 20%, as compared to the previous machines generation.
The working parameters of each pitch are stored in the POSYC® control pc; the operator can select the required machine pitch directly from the touch screen.
Easy and low-cost maintenance
The interchangeability of the mechanical and electronic components and the diagnosis functions on the control panel make the technical interventions and the programmed maintenance quicker and easier; moreover, they optimize the resources, in order to preserve the machines efficiency for long.
User-friendly man-machine interface
The POSYC® control panel, sliding on a boom running the whole length the machine (fixed on LSK ERGON models), enables even less expert operators to easily and effectively run the packaging machine, thanks to an intuitive interface, a touch screen display and diagnosis functions and real-time technical support available on the POSYC®.
