US 5,401,941 A · Apparatus for the inductive cross-field heating of flat material

Abstract

An apparatus for the inductive cross-field heating of flat material includes a plurality of mutually opposite induction loops being disposed above and below the flat material. At least one pair of induction modules is formed of two induction modules being adjustable independently of one another in their position relative to the flat material. Each induction module has two mutually opposite U-shaped induction loops having geometries and dimensions which are invariable, base legs which can be positioned in such a way that they terminate at least a predeterminable distance in front of one edge of the flat material and within the width of the flat material, and two side legs which can be positioned in such a way that they project at least a predeterminable distance beyond the other edge of the flat material. The induction loops of the two induction modules of a pair of induction modules are open towards oppositely directed sides, with the result that the side legs of only one induction loop project beyond each edge of the flat material.

Dependent claims

An apparatus for the inductive cross-field heating of flat material, comprising:

at least one pair of induction modules being adjustable in position independently of one another relative to a flat material to be heated, said induction modules defining a flat region for receiving the flat material to be heated,
said flat region having edges defining a width corresponding to a width of the flat material;
each of said induction modules including two mutually opposite U-shaped induction loops having invariable geometries and dimensions and being disposed above and below said flat region, said induction loops having base legs positioned a predetermined distance from one of said edges of said flat region and within said width of said flat region, and said induction loops having two side legs projecting a predetermined distance beyond the other of said edges of said flat region;
and
said induction loops of said pair of said induction modules being open towards oppositely directed sides and only said side legs of said induction loops each projecting beyond a respective one of said edges of said flat region.
