A winding core with improved beam and hoop strength and diminished friability and method for manufacturing such a core are provided, the method for making the winding core comprising: providing a wood fiber core, applying an adhesive to the wood fiber core, and sliding a tube or sheath onto the wood fiber core.

A spool for winding strand-shaped material having flange discs (22, 24) with an outer flange surface and an inner flange surface (21, 23) as well as a method for manufacturing the spool. The discs have a central through bore (30) that is surrounded by an annular recess (25) with an annular wall (26) positioned in the inner flange surface. A tubular spool core (10) has front surfaces which are connected in a materially bonded manner to the annular wall (26) inside the annular recess (25) of the flange discs (22, 24), wherein at least one channel (32) is provided next to the annular wall (26) inside the annular recess (25) for receiving liquefied connection material. The spool core (10) has approximately the same diameter as the annular wall (26) inside the annular recess (25).

A paperboard carrier suitable for use with textiles may include one or more strips of paperboard secured together to form a hollow tubular body, the body having an outer surface, and a coating covering some or all of the outer surface. The coating comprises a coating agent such as a silicon resin dispersed in a solvent such as isopropyl alcohol and little or no water. The coating may be applied to the outer surface by using a plurality spray nozzles arranged axially or circumferentially about the carrier.

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.

A rebar tie wire reel (110) for a reinforcing bar binding machine has a first flange (118), a second flange (120) spaced from the first flange, a hub connecting the first and second flanges and a wire (124) wound around the hub. The first flange (118) has an outwardly facing major face (134) and an outer periphery. The outer periphery is defined by a plurality of edges (170, 172, 174, 176). The plurality edges include a first edge (170) and a second edge (172) that are configured such that, in use, an amount of rotation of the rebar tie wire reel can be determined using signals provided by a movable element of a contact sensor when during rotation of the wire reel, the first edge, major face and the second edge successively travel past the movable element.

An assembly comprises a substantially cylindrical tape winding surface and first and second flanges co-formed with the winding surface to form a unitary hub structure. The tape winding surface extends along an axis from a first end to a second end, and the first and second flanges extend radially from the first and second ends of the tape winding surface, respectively. The tape winding surface and the first and second flanges are co-formed of a unitary hub material having a Young's modulus of at least about one million psi.

The tubular core (1) for tissue paper rolls consists of at least one tape (10) of tissue paper with one or more spirally wound tapes, such that the pitch of the winding helix is much smaller than the width of the tape (10) itself, so that two consecutive coils (S) are partially overlapped. In the tubular core (1) there may be several tissue paper tapes (10) wound simultaneously in relative helical coils preferably offset along the longitudinal axis of the same tubular core (1). The coils (S) of each tape (10), in the areas in which they are partially overlapped, are mutually fixed by means of an adhesive film (2) interposed between them. The adhesive film (2) is preferably continuous according to the winding direction of the coils (S) themselves. The presence of said adhesive films (2) produces a solid connection between the helical coils (S) and confers the necessary structural resistance to the tubular core (1) to receive, for wrapping on it, a tissue paper roll for hygienic use or domestic or other tape material.
