Abstract

1412019 Supports for extrudants INDUSTRIE PIRELLI SpA 7 Dec 1972 [17 Dec 1971] 56536/72 Heading B5A Apparatus for producing wire reinforcing belting by longitudinally cutting wire-reinforced tubing as it is extruded comprises a support for ensuring that the spacing between adjacent wires remains constant as the tubing is opened up to the flat belting. The support may be shaped as shown, may be metallic, may be discontinuous and may be provided with freely rotatable ball bearings or rollers to facilitate movement of the tubing thereover. The required shape of the support may be determined experimentally by applying weights (F, Fig. 7) and flexure springs (19) to a series of wires (18, Fig. 7) supported on a pair of spaced apart brackets (12, 13).
