Coating Laminating

Rainbow

The Rainbow M is the solventless version of the new generation of Uteco digitally controlled laminators. Joint partnerships with high level technical partners has allowed Uteco to further improve the capabilities and performance of its product  line.

An example of this innovation is the auto-recognition capability of the Rainbow to identify different web types (extensible - semirigid - rigid) being laminated and to automatically adjust the laminator to the apporpriate tension curves.

The heart of the Rainbow M is its coating unit design. With its special configuration, the metering, transfer and coating rollers are always in contact irrespective of roller heating, type of adhesive and machine speed.

The special contact profile of the coating rollers and the pneumtically  controlled  action of the transfer roller makes it unnecessary to readjust its position during machine operation. This system assures uniformity and accuracy of adhesive metering  at any speed  thus eliminating  the "tunneling" effect while reducing misting.

The Rainbow M's configuration positions the laminating nip just after the coating unit thus guaranteeing the opportunity of curling and contamination of thw web. 
The machine supervisor and the ability to change the roller sleeves on the machine ensure very short changeover times. This compact machine is equipped with shaftless winders which are motorized by vector drive brushless motors  supplied by Control Techniques.

Main options

• Mixer head for different types of adhesives.
• Corona treaters  both for  primary and secondary substrate
• Automatic shafted or shaftless winders for rolls of varyind diameter.
• Logipack® roll and core handling system

Mistral

The Mistral is the multiprocess, fully digital controlled version of the Uteco. 
The duplex Mistral laminator is equipped with interchangeable trolleys. They allow the use of up to ten different coating and laminating technologies;

• Solvent based lamination
• Water based lamination
• Solventless lamination with adhesives
• UV based lamination
• Water based and solvent based lacquering with rotogravure trolley
• Water based and solvent based lacquering with semi-flexo trolley for heavy coating weights
• PVDC coating
• In register Cold Seal coating of on a pre-printed reel
• One color gravure in-register printing
• Wax and Hot Melt coating and lamination

The Mistral is offered in two versions. The Mistral M is provided with a 6m drying tunnel and double support frames for lamination. The Mistral MC (compact version) is supplied with a 5m drying tunnel and a single support frame. The Mistral is equipped with a double stack, high efficiency, drying tunnel with low solvent retention values.  It is easy to maintain with a lift open top that slides towards the operator side for easy cleaning of both the air nozzles and path rollers.  

Main options:

• Mixing unit for the use of different solventless adhesives (supplied with the solventless trolley)
• Additional structure, unwinder and lamination nip to perform wet bond lamination.
• Automatic LEL system when using solvent-based adhesives
• Various drying systems can be used.
• The distance between the air nozzles and web between infeed and outfeed of the tunnel can be easily adjusted.
• Corona treaters for both primary and secondary web.
• Shaftless winders for reels of varying diameters
• Logipack® roll and core handling system
