A core member is provided for storing shrink film. The core member includes a plurality of rollers, each having a disc and a core extending upwardly from the disc. The plurality of rollers are aligned longitudinally along an axis and laterally along a plane. The plurality of rollers are rotatable to wind the shrink film about the rollers.

The invention concerns a splicing facility for splicing material webs. The splicing facility comprises a first dispensing device for dispensing a finite first material web from a first material web roll, a second dispensing device for dispensing a finite second material web from a second material web roll, a third dispensing device for dispensing a third material web, a first splicing device for splicing together the finite first material web and the finite second material web to an endless material web and a second splicing device for splicing together the third material web and the finite first material web or the finite second material web to the endless material web. The first splicing device and the second splicing device are arranged at different heights.

A continuous winding method produces a continuously wound electrical device, such an undulator. A continuous tape is wound about a series of turn around pins and in grooves in a magnetic core. A plurality of winding stacks are created, each transitioning to the next sequential stack by a transition tape portion extending from one turn around pin to the next turn around pin, which is position opposite with regard to the location of the pin on the magnetic core.

The invention relates to an apparatus for a single-track or multitrack provision of web-like interleaved sheet material at a cutting region in which products supplied on one track or on multiple tracks are cut into slices and interleaved sheets are introduced which are cut off from the provided interleaved sheet material in the cutting region, comprising an output device which is configured to eject at least one material web into the cutting region, wherein the output device comprises at least one driven feed roll and at least one counter-unit which forms a feed gap for the material web together with the feed roll.

The invention relates to an apparatus for a single-track or multitrack provision of web-like interleaved sheet material at a cutting region in which products supplied on one track or on multiple tracks are cut into slices and interleaved sheets are introduced which are cut off from the provided interleaved sheet material in the cutting region, comprising devices for transporting at least one material web from a material store to the cutting region, wherein a connection device is provided which is integrated into the apparatus and which is configured to connect consecutive material webs to one another on the path between the material store and the cutting region.

The invention relates to an apparatus for a single-track or multitrack provision of web-like interleaved sheet material at a cutting region in which products supplied on one track or on multiple tracks are cut into slices and interleaved sheets are introduced which are cut off from the provided interleaved sheet material in the cutting region, having a material store; and having a removal device which is configured for a removal of a material web from the material store, wherein a loop store in which the material web forms a loop is provided for the material web.

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 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 substrate is spirally wound around the core to form each spirally wound portion of the first plurality of spirally 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.

The present invention relates to apparatus and methods for winding and unwinding web materials, the web materials having a plurality of narrow lanes which form a spool. In a first aspect of the invention each lane of web material is defined by a width measured in the axial direction of the spool and between a minimum and a maximum radial height measured radially from a central axis of the spool. Each lane is wound, in turn, with web material up to the maximum radial height, the web material is folded by a first, second, third and fourth folds so that the web material is realigned parallel to the adjacent lane and wound to form the adjacent lane.

A continuous winding method produces a continuously wound electrical device, such an undulator. A continuous tape is wound about a series of turn around pins and in grooves in a magnetic core. A plurality of winding stacks are created, each transitioning to the next sequential stack by a transition tape portion extending from one turn around pin to the next turn around pin, which is position opposite with regard to the location of the pin on the magnetic core.
