In a belling machine and in a method of forming a socket at the heated end of a pipe, an end of a pipe made of thermoplastic material on which a socket is to be formed is heated until it is in a deformable state, inserted in a forming chamber and formed into a socket shape. Process air, taken from a compressed air source, is conveyed into an evaporator of a refrigerating machine using a refrigerant recirculating in a closed circuit and passes through the evaporator, resulting in transfer of heat from the process air to the refrigerant inside the evaporator. The process air is then conveyed to the forming chamber through an inlet, at least to cool the material of the end of the pipe at least by means of a process air flow inside the forming chamber.
A belling machine (1) forms end sockets equipped with an integrated seal on pipes (3) made of thermoplastic material using a forming mandrel (4) on which an annular seal (5) was previously placed, diametrically expanded, coaxially and in a predetermined position.
