PCT No. PCT/DE96/00339 Sec. 371 Date Oct. 20, 1996 Sec. 102(e) Date Oct. 20, 1996 PCT Filed Feb. 20, 1996 PCT Pub. No. WO96/26369 PCT Pub. Date Aug. 29, 1996A roller arrangement has a magnetic circuit that includes two rollers. The magnetic circuit consists of a cylindrical magnetic core, several poles axially distributed on the magnetic core, a cylindrical exciter and control windings arranged between these poles, a magnetic shell that encloses the whole circumference of one roller and is made of two parts separated by a ring-shaped secondary air gap, and a continuous magnetic shell in the axial direction arranged at the outer circumference of the other roller. When used to process webs of material in the textile, paper, plastic and metallurgical industries, this electromagnetic roller arrangement achieves high quality standards with a high productivity. |
