<p>This is a new equipment for the drying of water dispersion glue (with polyurethane, neoprene and natural or synthetic rubber base, both mono and bi-components), after the said glue has been spread on the uppers and/or soles: it can be integrated with other processes, and in particular, with carding, spreading and reactivation (heating phase of the supports in order to them press). This equipment consists of a modular system composed of one or more chambers, inside which some uppers and/or soles are placed on supports; decompression is then created thus allowing controlled and rapid evaporation and consequently the glue is dried. The temperature can be fixed beforehand and increased by a source of heat.</p> |
