Abstract: 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.

Abstract: A spool comprises a three-dimensional substrate and a core. The three-dimensional substrate comprises a plurality of projections extending outwardly from a plane of the substrate. The spool comprises a first plurality of spirally wound portions and a first plurality of helically wound portions.

The spirally wound portions of the first plurality of spirally wound portions are located next to each other along a longitudinal axis of the core between a first transversal side edge of the core and a second transversal side edge of the core. The substrate is helically wound around the core along the longitudinal axis of the core to form each helically wound portion. Each helically wound portion extends between two adjacent spirally wound portions of the first plurality of spirally wound portions.

Abstract: The present invention relates to a lower thread bobbin for a sewing machine able to hold a thread, the bobbin comprising a crescent moon-shaped winding part on which a thread can be wound and a crescent moon-shaped securing part for covering the winding part on which the thread has been wound.

Abstract: A roller mounted onto a fabric winding machine to roll up fabric aims to solve the shortcomings of the conventional rollers that tend to cause fabric skewing during fabric rolling and are difficult to remove due to a lengthy structure. The roller of the invention has an outer diameter gradually enlarged towards two ends, and includes a first half roller and a second half roller that have respectively a first positioning portion and a second positioning portion at one end corresponding and fastenable to each other. The greater diameters at two ends allow the fabric to be rolled up on the roller without skewing. The two pieces design of the roller makes each piece shorter and removing from a bundle of rolled up fabric easier. The roller thus formed can facilitate fabric rolling and removal thereof.
