METHOD AND DEVICE FOR COOLING SEMI-FINISHED PRODUCTS IN THE FIELD OF THERMO-FORMING AND/OR THERMO-ADHESIVE BONDING OF SAID SEMI-FINISHED PRODUCTS

摘要

A device for cooling semi-finished products, in the field of thermo-forming and/or thermo-adhesive bonding of such semi-finished products, comprises: a rigid casing (101) with an inlet (108) and an outlet (110); an auxiliary casing (104) impermeable to gas and placed within the rigid casing (101). A first volume (106) is delimited between the rigid casing (101) and the auxiliary casing (104) and a second volume (107) is delimited within the auxiliary casing (104). The auxiliary casing (104) is configured for containing a semi-finished product (2) comprising at least one thermo-plastic or thermo-adhesive element in an at least partially molten state. Control devices are operationally coupled to the inlet (108) and to the outlet (110) and are configured for executing the following procedure: introducing a gas at a first pressure (P1) through the inlet (108) and discharging the gas at a second pressure (P2), lower than the first pressure (P1), through the outlet (110) in order to generate an expansion and a cooling of the gas contained within the first volume (106), to cool the auxiliary casing (104) and the semi-finished product (2) and to determine the cross-linking of the thermo-plastic or thermo-adhesive element.
