Machine for winding flexible material
Abstract
Abstract A package of flexible, particularly springy material, is produced by a winding in the nature of a universal wind on a spindle having spaced curved ends and a cross section of oblong shape, a radial hole being built into the package substantially at the center of one of the sides of the oblong, and the flexible material being fed out from the interior of the package through this hole by means of a payout tube inserted in the hole and extending into the open central interior of the package where it flares outwardly. The completed package is thicker in the elongated sides than in the substantially semi-cylindrical end portions because the crossovers in the end portions are spaced further apart than in the side portions. Thus when one or both of the side walls are flattened, as by insertion in a package, the flattened side wall portions bulge inwardly so that the interior axial space within the package is substantially in the space of a dumb-bell or kidney with the interior walls closer together at the center than at the sides. A removable part inserted and held in the payout tube has a member engaging the opposite interior wall to stabilize the package during shipment and handling.
