Technical Features

Hot Melt Lamination Line – mod. LHM

The most important hot-melt application systems are the multi-roller system and the engraving roller system. The use of proper extruders and melters guarantees a proper feeding of the hot-melt adhesive to the application area.

The main differences between the two application systems are the following:

- The multi-roller system allows the application of a higher add-on (coated weight) and can only apply a uniform layer of adhesive. On the other hand, the add-on (coated weight) can be easily changed by changing the speed at which the coating roller revolves.

- The engraved roller system allows the application of an adhesive in dots and therefore the coated/laminated materials are breathable, they have a soft textile feel and lower add-ons can be applied. In addition, the dots of adhesive applied by the engraver roller remain on the surface of the materials and thus means that more adhesive is not used than is necessary. The add-on (coated weight) and shape of the dots is determined by the engraving: it is therefore extremely precise and remains constant. Different shapes mesh and different volumes can be chosen, depending on the application. However, a different engraved roller is needed to change the add-on. If different add-ons must be coated, due to the materials to be coated/laminated being different with different features, a range of different engraving rollers is required.

The applications of hot-melt adhesives/materials in industry are extremely varied.
Through the multi-roller coating system, the following items can be produced:

Self-adhesive materials: (non-woven/woven fabrics, foams, plastic films etc. can be coated with a self-adhesive hot-melt) these materials are used in the shoe-making industry to produce insulation materials
Plasticized materials: woven fabrics, used for instance to produce plasticized tablecloths, coated by thermoplastic hot-melts
Back coating: for upholstery fabrics and for a black-out finish (by coating thermoplastic EVA hot-melts)
Laminated materials: (non-woven/woven fabrics, foams, plastic films etc.) using both thermoplastic hot-melt adhesives and reactive PUR adhesives produces materials for the upholstery industry to the automotive industry, for example.

Through the engraving roller system, the following items can be produced:

Dot-coated materials: (non-woven/woven fabrics etc. coated with thermoplastic hot-melts) used as interlinings
"Network shaped" or dot-coated materials: these materials are coated with thermoplastic hot-melt adhesives and become adhesive when heated at the adhesive melting temperature. They can be used for many different purposes; for example, non-woven fabrics are used to cover the interior surfaces of vehicles
Breathable but waterproof laminates: used in the garment and shoe industry and is obtained by laminating a membrane (i.e. Goretex®) to fabrics
Breathable laminated materials: (non-woven/woven fabrics, foams, plastic films etc.) uses both thermoplastic hot-melt adhesives and reactive PUR adhesives; used in different fields from upholstery to the automotive industry etc.
