Abstract

1,098,440. Extrusion moulding machines. CROMPTON & KNOWLES CORPORATION. June 20, 1966 [Oct. 23, 1965], No. 27390/66. Heading B5A. The barrel 14 of an extrusion machine is provided peripherally with radially extending fins 18, see also Fig. 1 (not reproduced), which together with a longitudinally extending hood 40 provide a cooling system for the barrel. Air at room temperature is forced by a blower 42 through opening 44, between and over fins 18 and out of opening 46. To assist the flow, a deflector 80 may be provided. External casing 62, 68 has windows 64, 70 normally closed by covers 66, 72 respectively. Opening 46 is closed by a cover 76 should the barrel need to be heated, e.g. by heating rods (28), Fig 1 (not shown).
