Abstract

1,185,444. Wound articles. MICAFIL A.G. 2 April, 1968 [31 May, 1967], No. 15878/68. Heading B8G. [Also in Divisions C3, D1, D2, H1 and H2] A wound article is made by impregnating a paper strip with resin so that a continuous zone within the thickness of the paper remains free of resin, winding the impregnated strip upon itself, hardening the resin (or permitting it to harden), filling the resin-free zone of the strip with a liquid resin or polymerizable monomer and hardening the liquid (or permitting it to harden). The impregnating resin and liquid resin or polymerizable monomer may be the same or different. The liquid resin or polymerizable monomer can be drawn into the wound paper strip under vacuum or forced in under pressure. In specified embodiments phenolformaldehyde resin or epoxy resin is used for impregnating the paper strip and styrene monomer is used as the liquid. The impregnating resin may be applied to the paper strip prior to or during winding. The paper strip may be wound on a transformer core.
