Method for expansion of tubular article, involves pulling tubular article over arbor, where the tubular article is pulled continuously over overhung arbor, and arbor is held from retaining unit by magnetic and electrical field

摘要

The method involves pulling the tubular article over an arbor (10). The tubular article is pulled continuously over an overhung arbor. The arbor is held from a retaining unit in contactless manner by a magnetic and electrical field. The tubular article is pulled continuously by a continuous and circulating annular gap (30) between the arbor and the retaining unit. An independent claim is included for a device for expansion of a tubular article, particularly a net hose.
