787,932. Continuous-casting machines. PROPERZI, I. Oct. 25, 1955 [Nov. 2, 1954], 30519/55. Addition to 764,193. Class 83 (1). In a machine of the type described in the parent Specification and also Specification 673,801, which are referred to, the annular member 15 having the casting groove 17 is provided internally with reinforcing and cooling fins 17<SP>1</SP> and has its peripheral borders 391, 39<SP>11</SP> folded back to form two lateral channels 46, 461, and means are provided for introducing a coolant into said lateral channels. The casting wheel is supported on a shaft 23 rotatably mounted in a support 24, and through which coolant may be introduced to the interior of the wheel, and exhausted therefrom through a pipe 26. The lateral channels 46, 46<SP>1</SP> are closed by fixed annular members 30, 31 having internal cavities 32, 33 through which coolant under pressure may circulate, and communicating through holes 34, 35 with the channels 46, 46<SP>1</SP>. Gaskets 38-41 form watertight joints between the casting wheel and the members 30, 31, and said members are joined together over part of their periphery by members 42, 43, having internal cavities 44, 45 which may be supplied with coolant under pressure, which will pass through holes 49, 50 on to the metal band 18, and discharge through an aperture 51. In a modification, Fig. 7, transverse holes 57, 57<SP>1</SP> place the interior of the wheel, to which coolant is fed, in communication with the lateral channels 46, 46<SP>1</SP>. The coolant spaces on each side of the wheel communicate through hollow bolts 16<SP>1</SP>, which hold the side walls 13, 14 of the wheel together, and the coolant discharges through a pipe 55.
