MP 150 - Overlapping cardboard sleeve packers up to 150 ppm


The MP series includes automatic machines for the packaging of plastic, metal, cardboard and glass containers in overwrapping cardboard sleeves.

MP series packers can achieve an output up to 300 packs per minute, depending on the machine model and on the product to be packaged. Low or medium capacity containers can be packed in OTT (Over The Top) or NT (Neck Through) style. For shaped products, the pack can be strengthened by adding a top/bottom retaining flap which keeps the containers steadier inside the cardboard sleeve.

The pack collations can vary according to the containers shape and dimensions; in general, the most requested collations are: 1×3, 1×4, 2×2, 2×3 and 2×4. All MP models feature an electronic grouping system; the change-over is manual.

  1. In the machine infeed zone, a group of guides accurately lines up the loose containers carried by a conveyour belt featuring low-friction chains made of thermoplastic material.
  2. In the pack formation zone, the containers are clustered in the required format through electronically synchronized dividing combs, operating in continuous motion. At the same time, a cardboard blank is placed upon the products in transit.
  3. A mechanical device folds down the two edges of the cardboard blank; then the pack bottom is sealed with hot melt glue. The choice of “hot melt glue sealing” instead of “mechanical tucked-in closure” ensures more rigid and steady packages.
  4. In the models equipped with a rotodivider, the packs at the machine outlet can be turned by 90° or distributed on several lanes, before being conveyed to another packaging machine or directly to the storage area.

Modular structure

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.

Operational flexibility

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.

Continuous motion pack formation

The continuous motion packaging system ensures a fluid production process and protects the containers from strokes, thus granting more reliability, a better quality of the pack and a reduction of mechanical wear.

Thermoplastic material dividing pins

In the pack formation zone, the use of dividing pins made of thermoplastic material, which last longer than those made of metal, reduces the machine noise and protects the fragile containers (such as glass containers) and their labels.

Multi-pitch configuration

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®.
