摘要： 646,296. Extruding. McKECHNIE BROS., Ltd., RAE, J., and DUKES, A. H. Oct. 18, 1947, No. 27927. [Class 83 (iv)] A press for extruding rod, shaped strip or like stock is associated with coiling means comprising a rotatable pan within which a removable coil holder is concentrically mounted, the strip being guided from the press by means of a shoot which delivers it tangentially into the annular space between the pan and the coil holder. A pan 1 is keyed to a vertical spindle 2 driven by an electric motor 3. Within the pan is a removable coil-holder 7, 8 adapted to rotate with the pan. The extruded product is led tangentially into the space between the pan wall and the hub 7 of the coil holder by a shoot 10 preferably of rectangular crosssection which may be downwardly inclined or which, as shown may have a hinged flap 11 to direct the work towards the bottom of the pan. The speed of the pan is adjusted so that the coils do not touch either the pan wall or the hub 7 of the coil-holder. Preferably the crosssectional dimensions of the shoot are considerably larger than those of the extruded stock.
