ABSTRACT:
For guiding flexible material wound in a figure-8 package with inner end feedout, a coil is enclosed in a container with walls of corrugated cardboard. The payout of the material is guided by a tube having a flange adjacent the outer end, and two outwardly extending projections between the flange and the outer end, leaving a space therebetween. The inner edges of the projections are slanted in opposite directions. The tube is inserted into a coil, which is then inserted into a container formed of corrugated material. The corrugated material has an opening equal in diameter to the diameter of the tube and notches on either side of such opening extending in the direction of the corrugations. The outer end of the tube is brought through this opening, with the projections extending through the notches, and is then turned by 90.degree.. The thickness of the cardboard is slightly less than the space between the projections and the flange. Turning the tube causes the notches to ride up on the wall and to dig into it, so as to prevent accidental turning of the tube to an unlocked position. The projections rest against uninterrupted corrugations in the wall of the container.
