Hot-Melt Textiles: direct application of thermoplastic polymers in granule form and/or reactive polymers in special cans. The hot-melt polymer, melted by an extruder or fuser, is applied directly to a substrate (woven, foam, non-woven, membrane, film, paper, etc.) either by engraved cylinder or full-coating. Thereafter, in the case of bonded products, the second substrate is offered to the first and the assembled layers are cooled by contact with a chilled roller.
Hot-Melt Panels: full-coating hard substrates and wood panels with hot-melt PUR (reactive polyurethane) can give the end user significant production and quality advantages over conventional gluing systems. The technology employed is based on an exclusive method of heating the dosing cylinders, patented by Monti Antonio, which ensures perfectly uniform distribution of the polymers over the selected substrate.
Film / Web: heat-fusible film is unwound from a roll and fed into a calender together with the substrate being processed. On entering into contact with a heated cylinder, the film is melted and, in case of plasticization, adheres to the surface of the substrate. In the case of bonded products, the film is sandwiched between two substrates and melted - likewise by the heat from the cylinder - gluing the two layers together. Where breathability is important, the same process can be adopted using heat-fusible webs.
Foils / Effects / Micro Dots: used normally for fabrics and leathers, special effects can be either transferred from film, or rotary / screen printed with glue. These effects can also be enhanced by the application of metal foils, if desired. The machines used for this type of process are calenders with a heated cylinder and a pneumatic pressure cylinder. The micro dot finish is a similar process; micro dots are applied using a high pressure hydraulic cylinder.
