摘要： An apparatus for heat shrinking packages, comprising means for moving having an active surface configured for receiving one or more packages and for displacing the one or more packages along a predetermined operating path, a heating fluid circuit configured to circulate a heating fluid, a control unit operative on the heating fluid circuit, the control unit being configured to control circulation of the heating fluid in the heating fluid circuit, a chamber having an opening and being configured for receiving the one or more packages positioned on the active surface and for heat shrinking the one or more packages based on circulation of the heating fluid in the heating fluid circuit, and means for forming a liquid curtain arranged at the opening and configured to define a liquid curtain along the opening, the liquid curtain separating an inner volume of the chamber from an ambient atmosphere external to the chamber. Optionally, the apparatus further comprises a cooling liquid circuit configured to circulate a cooling liquid, and the control unit is operative on the cooling liquid circuit and configured to control circulation of the cooling liquid in the cooling liquid circuit. The control unit is further optionally configured to control the cooling liquid circuit to supply the cooling liquid to the means for forming the liquid curtain. A method for heat shrinking packages is also provided.
