Abstract
In a package formed of a plurality of layers each composed of a number of figure 8 winds with the cross-overs progressing around the package and with a radial opening extending from the periphery of the package to the axial opening through which radial opening the inner end of the material is led out, a funnel is provided with a stem positioned in the radial opening and with its mouth substantially at the mid-plane of the package. The funnel has a width in the axial direction of the package at least substantially as great as the axial length of the package. The funnel may be mounted in such a way that it can wobble slightly. The funnel guides the loops falling off of the inside wall of the package so as to prevent birdsnesting and provide for continuous and rapid payout.
