A winding core with improved beam and hoop strength and diminished friability and method for manufacturing such a core are provided, the winding core comprising: an extruded wood fiber core member; and at least one preformed paper shell member having a split seam parallel to its major axis, the shell being adhered to an exterior surface of the extruded wood fiber core member and a secondary shell of wooden staves.

A coreless roll of absorbent sheet products is made of a spirally wound web of absorbent substrate including at least two superposed plies of absorbent substrate, the web of absorbent substrate being wound such as to define an axial hollow passageway centrally positioned relatively to the coreless roll and extending from one edge to another edge of the coreless roll. The web of absorbent substrate further includes a stiffening insert, the stiffening insert being inserted in-between two superposed plies of absorbent substrate, the stiffening insert being positioned such as to line the axial hollow passageway, the stiffening insert having a length such that the stiffening insert extends at least around three quarter of a circumference of the passageway, preferably substantially completely around a circumference of the passageway.

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.

The present invention relates to a stabilizing center core for stabilizing a coil of duct or cable. The stabilizing center core comprises a center tube having a first and a second end. A first plate element is arranged at the first end of the center tube, and a second plate element is arranged at the second end of the center tube. The center core further comprises at least three third plate elements extending between the first plate element and the second plate element and arranged at angular distances around a circumference of the center tube, whereby a duct or cable that is wound around the stabilizing center core is supported by the third plate elements.

A spool configured to support a roll of material. The spool comprises an arbor, a first flange, and a second flange. The first flange includes a first plurality of flange panels that are rotatably connected to respective arbor panels of the arbor at a first arbor edge of the arbor. The second flange is connected to a second arbor edge of the arbor. The first flange is configured to transition between a retention configuration and an open configuration. In the retention configuration, the roll of material is substantially prevented from removal from the arbor along an arbor axis by the first and second flanges. In the open configuration, the roll of material is removable from the arbor and receivable on the arbor in the arbor direction.

The present disclosure is directed to a fibrous core comprising a fluted layer; and a liner disposed on the fluted layer. The fluted layer and the liner are helically wound defining a longitudinal core axis.

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.

A set of blanks for being repeatedly assembled into a reel configuration. A flange blank has pass through slots angularly spaced apart from one another and interlocking apertures angularly aligned with the pass through slots. Each pass through slot is spaced radially from an interlocking aperture. A core blank has a hub portion that is folded toward a core configuration in which it has an annular shape. Push tabs extend outwardly from the hub portion. Each of the push tabs passes through a pass through slot. Each push tab includes a spine and a pair of wings extending outwardly from the spine. The wings of each push tab bend away from a coplanar position with respect to their spine as the push tab is inserted in an interlocking aperture. The wings lockingly engage the flange blank when each push tab is lockingly received in the interlocking aperture.

A display rack mountable on a shelf of a store for showcasing first and second display boxes and wound flexible tubing. The display rack comprises front and rear support members. The display rack further comprises first, second, and third open sidewall support members each having a first end engaged with the front support member and a second end engaged with the rear support member. The display rack further comprises a first stall formed between the first and second open sidewall support members. The first stall is adapted to receive the first display box. The display rack further comprises a second stall formed between the second and third open sidewall support members. The second stall is adapted to receive the second display box. The front and rear support members support the front and rear portions of the first and second display boxes, respectively.
