<p>The plastic reel (1) is intended for winding wire, partic. steel wire such as used for tyre casings. It consists of a hollow cylinder (5) with a flange (7) at either and and having an internal support (13) at a distance (12) inside each of the flanges. The support consists of a rim extending at right angles to the cylinder axis, the axial distance (12) to the handle of the corresponding flange being at least equal to value defined as a function of the radius of the cylinder, the cylinder wall thickness between flange and corresponding support rim, and the modulus of laterla contraction of the reel material.</p> |
