A retractable dispenser device includes: an externally threaded multi-ply tube comprising a spiral wound first multi-ply material, wherein the first multi-ply material includes one or more inner plies and an outer ply, wherein the outer ply is wider than the one or more inner plies, wherein subsequent windings of the inner plies abut each other such that the outer ply overlaps at each subsequent winding forming an external thread; and an internally threaded multi-ply sleeve comprising a spiral wound second multi-ply material, wherein the second multi-ply material includes an inner ply and one or more outer plies, wherein the inner ply is narrower than the one or more outer plies, wherein subsequent windings of the outer plies abut each other such that the inner ply leaves a gap at each subsequent winding forming an internal thread.

Methods and apparatus to form tear-off paperband composites that adhesively attach a paper web to an empty web spool. In some embodiments, the paperband composite is applied in several layers to an empty web spool, each layer suitable for fixedly attaching a paper web to the empty spool. Multiple layers of paperband composite allow for use during multiple turn-up procedures with one layer of paperband composite used per turn-up procedure. In some examples, the paperband composite may be applied to a paper spool tangentially along the spool face and perpendicular to the axis of rotation of the spool. In other examples, the paperband composite may be spirally wrapped around the paper spool.

In some embodiments, the paperband composite is applied in several layers to an empty web spool, each layer suitable for fixedly attaching a paper web to the empty spool. Multiple layers of paperband composite allow for use during multiple turn-up procedures with one layer of paperband composite used per turn-up procedure. In some examples, the paperband composite may be applied to a paper spool tangentially along the spool face and perpendicular to the axis of rotation of the spool. In other examples, the paperband composite may be spirally wrapped around the paper spool.

A web splice for attaching two webs, such as paper webs used in paper converting operations. The web splice comprises a non-linear butt joint. The butt joint forms an acute included angle () with the side edges.

A paper roll and method of manufacturing. The paper roll includes a plurality of sheets spirally wound forming a roll. The roll includes a first end and a second end, wherein the first end forms an inner section. The inner section defines an axial passageway that extends from a first side of the roll to a second side of the roll. An adhesive that can stiffen the inner section joins the plurality of sheets of the first end. The method for manufacturing the paper roll includes winding the plurality of sheets about a low-friction tube to form a roll, applying an adhesive to the plurality of sheets at a first end of the roll forming an inner section having an axial passageway, curing the adhesive configured to stiffen the inner section, and removing the low-friction tube from the roll.
