A Re-user case for retaining a wound coil of filamentary material wherein first and second separate half-sections, each including mating projections and counterpart receptacles enabling the two sections to be releaseably joined and forming an enclosed case containing the wound coil and wherein the first and second half-sections are formed of injection molded impact resistant high intensity propylene; each of the half-sections including releasable locking members to join the first and second half-sections to one another to form the Re-user case; and the Re-user case including large and small diameter payout openings respectively accommodating a first payout tube for unwinding a coil of filamentary material or large diameter and a second payout tube for unwinding a coil of filamentary material of small diameter.

Re-user case

The combination of a backing plate member, a hollow tube and a container having coiled filamentary material therein for paying out filamentary material coiled in the container through the tube, with the hollow tube having an end portion including a pair of oppositely disposed projections and the side wall panel including a cut-out portion substantially conforming to the shape of the end portion including the opposed projections. The backing plate member comprising a substantially planar member made of a resilient material and having a cut-out portion and substantially conforming in shape to the shape of the end portion of the tube enabling passage of the end portion through the cut-out portion of the planar member, a first ramped surface being formed on an edge portion of each of the opposing projections and adapted to enable each projection of the tube to be rotated in a given direction onto the surface of the planar member thereby locking the tube with respect to the planar member.

A folding cone for retaining the windings of a wound package containing coils wound in a Figure-8 configuration with an axial opening extending through the longitudinal axis of the coil and a radial opening extending from the inner surface to the outer surface of the coils with a first member having a base portion including a pair of upstanding projections extending along the bottom thereof with a gap therebetween and an end portion shaped to be positioned within the inner end surface of the coils. The end portion and base portion extend to the gap and include spaced guide members each having opposed spaced porjections forming a channel and a second member having a second base portion and a second opposed end portion connected to the second base portion with the second base portion and second end portion being interconnected by at least a second strip member connected substantially perpendicular to the second base portion by a second fold strip, the second end portion being narrower than said second base member and being shaped to be positioned within the inner surface of the coil windings, the second strip member having an edge portion with an enlarged portion along a section thereof and adapted to be engagable in said channels with the second end portion folded perpendicular to the second base portion along the second fold line and the second base portion folded perpendicular to the first base member and the folding cone formed thereby being adapted to be held by the enlarged portion being retained in one of the channels.

Folding cone package design

In a winding wound in a figure-8 configuration, such as a universal winding which is known in the textile industry, the endforms of a spindle on which the winding is wound each respectively include openings enabling the projection therethrough of collapsing members such that the ends of the winding may be compressed to a substantially flat plane with the innermost winding. The mandrel is formed in two movable sections such that the two sections collapse towards one another with application of the compression force applied to each of the endforms.

Two-way collapsible mandrel with winding compression

Water-soluble wind stabilization segments are used to stabilize the winding of coils wound in a figure-8 configuration with a radial opening provided on the side of the winding such that the winding may be unwound from the inside out. The water-soluble stabilization segments dissolve when the winding is immersed in water, thereby obviating the need to physically remove such stabilization segments prior to unwinding the wound package.

Windings using water-soluble wind stabilization segments

A package for retaining material wound in a figure-8 configuration and including a radial hole extending from the central core space thereof to the outer periphery thereof is enclosed in a container having a preforated corner portion for feeding material from the winding. The winding is placed within a polygonally-sided insert having opposing sides engaging the outer periphery of the winding and including a feedout tube inserted in the radial hole for feeding the inner end of the material. Opposite sides of the insert engage the inner surfaces of the container with the feedout tube being aligned with the perforated corner portion. The bottom and upper surfaces of the container include intersecting cone sections for supporting the inner windings of the material.

Container with octagonal insert and corner payout

In a coil of material wound in a series of figure-8 coils with the crossovers progressing around the package but being interrupted at one point to provide a radial opening into the axial opening of the coil, in order to produce a thick-walled coil the material is first wound in a normal way with varying gains in order to produce a set of dense inner layers, while the outer layers are wound without variation in the gain to produce a honeycomb structure. The honeycomb section is of greater width (axially of the package) than the inner layers. A plurality of pins slidably mounted on a strip are pushed into the outside of the package through the openings in the honeycomb, whereafter the outer layers are compressed axially while retaining the pins within the outer layers. The pins permit payoff of the outer layers without danger of their collapsing and thereby forming kinks or twists within the package.

Coil of flexible material with inserts in outer wall

The invention relates to a package of material wound in a series of figure-8s with the cross-overs advancing around the package, and the cross-overs being omitted at at least one point on the circumference of the package to leave a radial hole into the center of the package for inner end feedout to allow payout without twist. This hole is ordinarily somewhat diamond shaped, with its major axis extending substantially perpendicular to the axis about which the material was wound. A payout tube is placed in that hole, this payout tube having an oval shape.

Package of flexible material with oval payout tube

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.

Tube for inner end feedout of flexible material and package utilizing

A tube for insertion into a coil of flexible material wound in a series of figure-8s with a radial opening extending into the axial opening through which the inner end of the material can be drawn out without twist has a flange spaced from its free end and a second flange adjacent the free end with the space between the two flanges being substantially equal to the wall thickness of a container in which the packaged coil is to be enclosed. The outer flange is interrupted at two points and has an outwardly bent portion. The tube is inserted from the outside into the radial opening of the coil, which is then placed inside the container with the outer end of the tube directed towards an opening in the container, which has notches therein. Upon turning the tube, the outwardly bent portions ride up on the wall of the container, so that the tube can be turned to a position in which the principal part of the outer flange engages against the outside of the wall. The tube is cut off so that it does not project beyond the outer flange. The sloping portions of the outer flange are provided with weakenings adjacent their inner ends, so that upon the assembly of the package these can be broken off and will no longer project from the outside to interfere with handling of the package.
