摘要:
A spool assembly includes a drum having a first axial end and an oppositely disposed second axial end. The drum includes an inner surface that defines a bore that extends through the first and second axial ends. A drum support is disposed in the bore of the drum. The drum support includes a first end and an oppositely disposed second end. The drum support has an exterior surface. The exterior surface of the drum support and the inner surface of the drum define a plurality of channels. A first flange is engaged to the first end of the drum support. A second flange is engaged to the second end of the drum support.

The present invention relates to an easily removable paper tube used for winding material, such as fabric, a band, a film, and so forth, and a method for successively using articles, each of which uses the paper tube, and, more specifically, to an easily removable paper tube and a method for successively using articles that use the paper tube, in which the paper tube is effectively removed, without deforming a roll of material wound around the paper tube, such use of the material enabled by releasing it from the inside of the roll with the paper tube removed, thereby increasing the unrolling speed of the material, and a first article and a second article, each of which includes wound material, are connected to each other for use, thereby allowing successive provision of the articles, and thus remarkably increasing a rate of successive production.

A collapsible reel having a high strength to weight ratio is provided. The collapsible reel comprises a core, around which a flexible media is wound, and flanges which prevent the wound flexible media from migrating axially off of the core. The core is formed of first and second blanks having hub portions and a plurality of spaced apart tabs projecting from the hub portions. To form the core, the tabs of each blank are folded and the tabs of the first blank are secured to the corresponding tabs of the second blank. The flanges are then adhered to the outer surface of the hub portions.

Perfected cable holder made of cardboard, or corrugated cardboard, comprising two flanges (11), and a support element (12) conformed as a drum and disposed between the two flanges (11), the support element (12) being obtained by bending at least a sheet of cardboard to define an internal surface (23) and an external surface (13) on which a cable (14) is suitable to be wound. The support element (12) is provided, in proximity to its ends, with protruding extensions (15) suitable to reciprocally connect the flanges (11) with the support element (12). Each of the flanges (11) comprises a first element (25) suitable to act as a containing wall of the cable (14) which is wound on the external surface (13) of the support element (12), and at least a second element (26) with a shape and size mating with those of the cross section of the internal surface (23) of the support element (12). The second element (26), in use, is disposed adjacent to the first element (25) and internally to the support element (12).

A core (28) for winding floor covering material, the core (28) being a hollow, wound paper tube having an integrally formed, longitudinally oriented indentation (32) configured to accommodate the starting edge (46) of the floor covering material (30). The core (28) eliminates the longitudinal crease often found on the final few square meters of floor covering wound around a conventional core (8).
