The present disclosure provides methods of winding substrates comprising three-dimensional features about a core to form a spool so that at least a majority of the three-dimensional features in one wrap of a lane of the spool are at least partially nested with a majority of the three-dimensional features in another adjacent wrap in the same lane of the spool. By at least partially nesting these three-dimensional features in adjacent wraps of a lane of the spool, the three-dimensional features may be at least mostly maintained in the substrates without significant compression during winding and storage of the spool.

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.

A roll of absorbent socks is provided with a liquid permeable sleeve that houses an absorbent layer with a superabsorbent polymer. Perforated regions are provided spaced apart along the length of the sleeve with a plurality of perforations through the sleeve and the absorbent layer. The perforations define the end of a first sock and the adjacent end of a second sock. Mechanical closure members are provided on opposed sides of and adjacent to each perforated region. When a sock is separated from the role, it has first and second longitudinally spaced apart ends that are closed by the mechanical closure members to prevent superabsorbent polymer from flowing out the ends of the sock.

An improved electronic component holder of the type having a reel of tape, wherein the tape has a back side, a front side, and may include small wells evenly spaced from each other and containing electronic components The improvement includes markings on one of the back side and the front side of the reel of tape containing the electronic components with a scale that will ultimately determine an amount of electronic components left on the reel of tape. The markings may include a means of determining quantity of components on a tape or length of tape by automatic identification or machine vision. The markings may be applied to tapes on reels containing components or to each piece of the component tape assembly, for example the cover tape or component tape, individually such as in a tape pre-print assembly on a newly manufactured cover tape reel.
