KEY POINTS:
REEL HANDLING
- Single axis unwinders and rewinder or double axis fully automatic unwinders and rewinder, according to customer's requirements
- Shaft or shaft-less reel locking
- The shaft-less system is provided with a pneumatic-mechanical expanding chuck system, to assure the operator's safety and to avoid core damage (cardboard, plastic or metal)
- The rewinder can be equipped with an innovative no-glue splicing system
 
COATING STATION
Multi-trolley coating station; the same frame can house a wide range of trolleys:
- Rotogravure trolley with 3-position doctor blade
- Rotogravure trolley with doctor blade chamber
- Trolley system for PVDC coating
- Semi-flexo trolley for solvent-base, water based coating and products for wet laminations
- Flexo trolley for solvent coating on alufoil
- Solvent-less trolley for single component and two component adhesives
- Rotogravure trolley for patterned cold seal application
 
 
SOLVENT TECHNOLOGY
High efficiency laminating machine designed to obtain the highest flexibility using a wide range of materials, plastic films, paper, alufoil, etc.
- Very quick trolley changeover due to the special engineering of the coating station
- Front trolley introduction into the coating station: an innovative concept
- Tool-free cylinder locking and user friendly connection to the driving gear
- The trolley carries the inking system designed for high production speed, using an adhesive rip-free system
- Driven smoothing bar on the coating output for water-based and solvent-based product; a frequency converter allows controlled variable results on the coating
- High efficiency horizontal drying system with variable opening nozzles
- User friendly accessibility to the drying system rollers to allow easy cleaning and maintenance
- Flexibility to the customer requirements
 
SOLVENT-LESS TECHNOLOGY
Our solvent-less coating station is provided with a triple control system to guarantee a precise coating weight consistency from zero to maximum speed, also while ramping up/down.
- Solvent-less adhesive can be heated from 25°C to 90°C, according to suppliers specification
- The top idler rollers are driven by flat belt
- The coating system consists of a "four roll system" of which three are independently driven
- Sleeve system on transfer roll: the sleeve change operation is carried out directly on the coating system within few minutes
- High efficiency drying system with side-lay or horizontal opening
- Precise gap adjusting with indicator to obtain an accurate coating weight
- Fast cleaning of metering roll by pneumatic opening
- Temperature controlled metering and coating rolls to guarantee process accuracy
- Flexibility to the customer's requirements
