Abstract
To produce a sheet used as an electric insulation material, a pasty beading (33) is continuously formed from a mixture of hardenable resin and muscovite- or phlogoptit-based mica powder preferably of electric quality. This beading passes into a calender or a band press which, by decreasing the thickness thereof, transforms it into a thin layer. The platelet-shaped mica particles are arranged in parallel to the layer plane. The building (33) may also contain, in addition to mica powder, other thinner and/or reinforcing materials. The formation of the building (33) is preferably carried out by means of an extrusion press wherein the resin, optionally liquid and without solvent, is mixed to the mica powder and a latent hardener (31) is then added to said mixture. Appropriately during the formation of the thin layer between two separation sheets (28), the thin layer may be directly bound to a carrier material band (29). When fabricating insulations for coils of electric machines by using said sheet, the synthetic resin contained in said sheet is allowed to harden.
