Benefits of technology

"The invention is about designing a spool that prevents caking of wires during an annealing process. The spool has a larger space between its winding layers at high temperatures, which reduces the pressure on the wires and prevents them from sticking together. The spool can also be designed to return to its original position when temperature returns to room level. This design prevents damage to the wires and ensures reliable performance of the spool."

Problems solved by technology

The individual wire turns can expand relatively unimpeded, however, in all embodiments of the spool during the annealing process owing to the expansion of the winding space, and the pressure exerted on these wire turns is as a result considerably reduced.

Embodiment Construction

[0021] The spool illustrated in FIG. 1 has two flanges 1 and 2 in the form of circular disks and having the same diameter. The flanges 1 and 2 consist of a metal having a high tensile strength, in particular of steel. They are arranged parallel to one another in the spool and are connected to one another by a core 3, which likewise consists of metal and, in the exemplary embodiment illustrated, is cylindrical. The elongate core 3 could also be conical. The mid-axes of the flanges 1 and 2 and the core 3 correspond to one another. A winding space 4 serving the purpose of receiving the winding material is delimited by the flanges 1 and 2 and the core 3.

[0022] The spool according to the invention consists of metal and is used for receiving winding material in the form of wire, which is wound on with a large number of turns and likewise consists of metal—referred to below as “wire” for short. The upper part of FIG. 1 shows a large number of turns 5 of a wire. Its material should have a ...

Abstract

The invention specifies a metal spool for receiving metallic winding material (5) in the form of a wire, which spool comprises two flanges (1, 2) in the form of circular disks, arranged parallel to one another and having the same diameter and an elongate core (3) connecting the flanges and having a circular cross section and smaller radial dimensions in comparison with the flanges (1, 2), the mid-axis of which core corresponds to the mid-axes of the flanges (1, 2). A winding space (4) for receiving the winding material (5), is delimited by the core (3) and the two flanges (1, 2). The dimensions of the winding space (4) in the direction of the mid-axis of the spool can be enlarged at an increased temperature. In addition, means are provided to bring the dimensions of the winding space (4) back to the initial position when the temperature returns to room temperature.

Description

CROSS REFERENCE TO RELATED APPLICATIONS [0001] This application claims priority under 35 USC §119(a) to German Patent Application No. DE102005060279.7 which was filed on Dec. 16, 2005. TECHNICAL FIELD [0002] The invention relates to a metal spool for receiving metallic winding material in the form of a wire, comprising two flanges in the form of circular disks, arranged parallel to one another and having the same diameter and an elongate core connecting these flanges and having a circular cross section and smaller radial dimensions in comparison with the flanges, the mid-axis of which core corresponds to the mid-axes of the flanges, in which spool a winding space for receiving the winding material is delimited by the core and the two flanges, and in which spool the distance between the flanges can be altered elastically by forces acting on them (DE 41 38 189 A1). BACKGROUND OF THE INVENTION [0003] These spools have long been known and available on the market. In the known technology...
