Thermocompression device for producing recyclable honeycomb plates and method implemented using same

A thermocompression device for producing recyclable honeycomb plates of the types supplied with sheets of recyclable material including a fabric and a thermoplastic material, the thermocompression device comprising:

• a plurality of drive rollers, a plurality of heated thermocompression rollers and a plurality of forming rollers having protuberances with a half-hexagon geometric shape;
• the thermocompression rollers and the forming rollers being arranged in pairs, and whereas the thermocompression device is defined by:
• an area for continuously heating and pressing the sheet, having at least a first infrared radiation heating element and the thermocompression rollers, wherein a temperature of the area for continuously heating and pressing is equal to or higher than the melting temperature of the thermoplastic material of the sheet,
• a cooling area for cooling the sheet, having a water-chilled cooling element,
• a calendering area for calendering the sheet, having at least a second infrared radiation heating element at a temperature equal to or higher than the melting temperature of the thermoplastic material of the sheet,
• a moulding area where the forming rollers are arranged at a temperature lower than the temperature of the calendering area,
• wherein the protuberances of the forming rollers are arranged in continuous rows distributed on an outer surface of each of the forming rollers, such that the rows are arranged cross-wise with respect to the direction for supplying the sheet.
