Abstract
A method of curing a non-metallic band impregnated with resin, which is wrapped about a leg portion of a magnetic core such that it overlaps a portion of itself, including the steps of tensioning the band, curing resin in the overlapped portion, and subsequently curing the remainder of the resin in the band in an oxygen-free atmosphere.
Claims5
A method of curing a resin impregnated non-metallic band such that the band retains a degree of flexibility, comprising the steps of:
- tensioning the band to a predetermined tension;
- subjecting the band to a predetermined vacuum while spraying the band with oil maintained at a predetermined temperature for a predetermined length of time.
A method of curing a resin impregnated non-metallic band, comprising the steps of:
- providing a magnetic core having a leg portion formed of a plurality of superposed metallic laminations;
- providing a non-metallic band impregnated with resin;
- wrapping said band about said leg portion, while overlapping at least some portion of itself;
- tensioning said wrapped band;
- curing resin in said overlapped portion while the band is tensioned to secure the band in the tensioned, wrapped configuration;
- and
- curing the remainder of the resin in the band in an oxygen-free atmosphere, to provide flexibility in the portion of the band associated with said remainder of the resin.
