A convolutely wound material having a tail and a body. The tail is bonded to the body with foamed adhesive.

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.

A mounting plate for holding a roll of wound material. The mounting plate comprises a body, a hub extending from the body for holding a core, and one or more spacers affixed to the body and extending beyond the body in the direction of the roll. Each spacer comprises an inner member which may contact the roll and one or more resiliently deformable legs extending outwardly from the inner member. The spacers can maintain contact with the ends of the roll and prevent the roll from being damaged due to telescoping or impacts with the mounting plates or other structures.

A wire reel is detachably provided in a housing chamber of a binding machine body which binds a reinforcing bar. The wire reel includes a cylindrical hub portion which winds a wire, and a pair of parallel flanges overhanging outward from both external peripheral ends of the hub portions. A side wall inside the hub portion is formed of light-transmitting portions which allow the light from a transmissive photosensor provided in the binding machine body to be transmitted therethrough.

A glass ribbon coated with a flexible material, the flexible coating forming a flexible web portion that extends from an edge of the glass ribbon at least one millimeter. The flexible web portion can be used to facilitate handling of the glass ribbon in a manufacturing process, and may include registration markings, or perforations, that further facilitate precise positioning of the ribbon.

Web-wound rolls with a web edge treatment with microspheres and processes to make the same are provided. The web-wound rolls include a substrate web having at least two web edges. One or more stripes of coated material are disposed adjacent to one or both of the web edges. The substrate web is wound upon itself in multiple revolutions about a central core, and each revolution is held substantially separate from the next by the one or more stripes of coated material.
