Laminating calander

It is the core of the machine and includes all devices for motion, actuators, drivers and associated equipments.

Built on a rugged frame, it supports the applicator, the head operator panel, the controls of auxiliary systems.

The front side houses the inlet of primary material, on which adhesive shall be applied; the upper side houses the secondary material inlet; the rear side houses the end product outlet.

Slot die applicator

slot die applicator

It is the module that carries out the contact coating of the primary material with the adhesive.

It is available in several working width, to be selected according production needs of end user.

Thermo-regulated hoses are connected to applicator, bringing adhesive from melters.

A pneumatic device (controlled by head operator panel) sets applicator in the working position.

Thanks to modularity of its components, this applicator permits a sharp precision in adhesive distribution, and the possibility to choose between different coating patterns .

Continuous cycle melter

This type of melter is used with thermoplastic Hot-Melt adhesives.

It permits continuous operation, as the raw adhesive level can be reset “on the run”.

At the end of working cycle, it shall be turned off; at production re-start (also after week-end stop) it can be started up.

After adhesive melting, working cycle can be run again.

This is made possible due to features of thermoplastic Hot-Melt adhesive; therefore this type of melter cannot be used with PUR type adhesives.

Continuous cycle melter does not need of cleaning unit.

Drum melter

This type of melter is used with PUR type Hot-Melt adhesives.

It uses standard size adhesive barrels (about 200kg) whose autonomy is related to specific application density and line speed set be operator.

Where line includes one drum melter only, it is not possible to run continuous production: once the barrel is terminated, the line shall be halted to replace the empty barrel with the new one.

At the end of working cycle, drum melter shall be turned off and operator shall initiate the cleaning cycle of applicator: PUR adhesive must be removed from applicator to prevent reticulation inside and clog the applicator.

At production re-start (also after week-end stop) drum melter shall be turned on and, after adhesive melting, working cycle can be run again.

This type of melter can be used either with PUR type adhesives and with thermoplastic Hot-Melt adhesives.

The presence of a drum type melter make necessary to include the cleaning unit in the line.

Cleaning unit

This unit is basically a reduced size melter, loaded with the special polymer used for applicator cleaning.

The unit shall be used at the end of a working cycle in which a PUR type adhesive has been used, prior to change to a thermoplastic Hot-Melt adhesive or before a line shut down (i.e. at the end of working day).

Cleaning operation is controlled from operator panel directly, with no need to carry out special or temporary connections.

Head operator panel

It is the interface between operator and machine control system.

A touch-screen panel, located on the right front side of the lamination head, provides for input and display of all running parameters:

Run, stop, maintenance, cleaning controls
Line speed setup
Working width setup
Controls of auxiliary systems eventually included in the line
Display of production meters counters
Display of alarm annunciator

Screen pages (graphic type) are simple and intuitive; 12” TFT screen is deemed quite familiar to operators.

Control cabinet

It is the “mind” of the line.

Generally located on the side of laminating head, this cabinet includes the PLC controller, taking care of running sequences, line safety shut down, power center of all motors and auxiliary systems eventually included in the line.

Panel front includes few controls only, necessary for line initial start-up: all normal running commands are originated from operator panels, located on the laminating head and melting unit.

Coating Patterns

The technology implemented on our machines permits to distribute polymer on the inlet support according four different patterns:
full coating	intermittent

multi-line	breathable

The operation neither require any mechanical modification to the machine, nor the interruption of the working cycle: operator just set the desired pattern on the panel.

Adhesives

Examples of several type of polymers

Our machines are not designed to work with a particular adhesive, specifically produced for the purpose.

In fact, it is possible to use a wide range of polymers, including:

Reactive Hot-Melt (normally known as PUR)
Thermo-plastic Hot-Melt
- Polyester
- Polyamide
- EVA
- Self adhesives
- Others

Reactive Hot-Melts are normally used for production of laminated textiles having wash-resistant features.

Instead, thermo-plastic Hot-Melt are normally used for production of laminated textiles not requiring wash-resistant features

Anyhow, our staff is at your disposal to suggest best solutions, based on specific application.

Advantages

In comparison with similar machines available to date on the market, Hot-Melt technology of our laminating machines, bear a number of clear advantages.

Adjustable coating width of the polymer

Working width can be set by operator from minimum to maximum value for which machine has been designed.

This allows the use of machine with supports having different width (in the design width range), via a simple touch on the operator panel.

The operation neither require any mechanical modification to the machine, nor the interruption of the working cycle.

Adjust of polymer specific density (g/mq)

With no need to carry out any mechanical modification on machine and during machine run, operator can easily adjust quantity of adhesive applied to each area unit of the support.

Coating specific density can be adjusted during a working cycle from a minimum of 0,1 g/mq to a maximum of 300 g/mq.

The operation neither require any mechanical modification to the machine, nor the interruption of the working cycle.

Constant polymer density

Machine control system provides for keeping constant the coating specific density (the quantity of adhesive applied per each surface unit of the coated support) upon modification of line speed.

When operator modify line speed, system automatically adjust the adhesive flow sent to applicator.

Thus, whether specific density is set to 9 grams per square meter, it is automatically kept either where line speed is set at 10 meter/min and where line speed is increased to 20 meter/min.

Variety of polymer coating patterns

The melting/application system permits to modify the coating pattern (full coating, multi-line, intermittent or breathing) simply acting on the operator panel.

The operation neither require any mechanical modification to the machine, nor the interruption of the working cycle.

Precision and regularity of polymer distribution

Lamination process ensure an excellent quality of end product due to the high uniformity of adhesive layer applied to the support.

This regularity is the basic reason of the great uniformity of the outlet product, maintaining high softness features, considering it is still a bonded textile.

Application on frame supports

The new Hot-Melt technology implemented on our machines permits to coat polymer also on frame based supports (for example plastic nets or large web based fabrics) with no polymer accumulation in the blank areas.

This feature allows to laminate the web fabric to another support, preventing the common adhesive stains on end product, stains that decrease its quality in the terms of clearness and softness.
