accurate than conventional control by hand or expansion bolt automa- tion, says Reifenhäuser. The main advantage lies in the use of motorised manual adjustment bolts in place of conventional thermal expansion bolts. The system was launched at K2022. “With this automation option, we can now offer our customers a perfectly coordinated overall system,” said Uwe Gaedike, managing director of Reifenhäuser
Extrusion Systems. “With Maku, we will establish the technology in the market and continu- ously develop it further.”

Common control Conair has implemented a common control across all its HMI-interfaced ancillaries – by adding a system for its dryers and drying equipment. Users can equip many of Conair’s drying
products with a control platform whose interface shares the same interactions and features as other Conair ancillaries. These include its desiccant
dryers, PET crystallisers, hot air dryers and hopper temperature controllers. “Introducing the DC-B Common Control across our drying product line represents an effort to create an identical user experience across virtually all of Conair’s upstream auxiliary equipment,” according to AJ Zambanini, drying products manager at Conair.
Its dryer customers now have a control system
that offers the same interaction style for through- puts above 15 lbs/hr, he added. “The same control interface is already available in our blending, conveying, and temperature control auxiliaries, so there’s much less training involved for an operator to understand and master the use of different equipment.” Since introducing the platform into dryers, it has added three new features. The first is an automatic Airflow Monitor, which
electronically measures the total airflow quantity (cfm) in all drying equipment – complementing automatic dewpoint monitoring – to ensure that the quality and quantity of drying airflow is correct. Secondly, it has ‘setback on’ input. Ordinarily, temperature setback is automatically
Laminate is a type of composite made of a combination of at least two materials. The properties of the laminate are the sum of the advantages of the constituent materials. The most frequently used components include various types of films, nonwovens, fabrics, mats, paper, aluminum foils, nets, etc. various coating techniques. BG PLAST uses a variety of coating and lamination technologies, enabling the production of a wide range of laminates.

Main parameters of the coating and lamination line: • Web width: up to 3,300 m • Lamination speed up to 120 m / min • Number of layers: 2-7
Lines for extrusion coating and lamination
Extrusion coating lines extended with additional unwinding unit enable the lamination of various materials, e.g. foil, nonwovens, fabrics, mats, paper, aluminum foil, mesh, etc., using the same line. The use of co-extrusion makes it possible to obtain an adhesive layer with different adhesi- ve properties on its both sides, which allows the joining of any materials.
