Abstract

1501676 Making laminated cores SIEMENS AG 26 Sept 1975 [30 Sept 1974] 39628/75 Heading B3A [Also in Division H1] A method of manufacturing electromagnetic components consisting of a laminated core and a winding comprises coating laminations with an adhesive resin, passing them in a stack through a heating zone to soften the resin and then through a cooling zone to harden the resin causing the laminations to adhere to one another, thereafter removing assemblies of required length from the stack, providing each assembly with a winding, impregnating the assemblies and windings with curable resin and heat treating to cure the resin. The laminations may be stamped from sheet metal which is precoated with adhesive, either entirely or with strips left uncoated at predetermined spacings so that the laminations at the end of each core in the stack have no adhesive or a reduced amount between them, thus facilitating separation. A polyester resin may be used both for the impregnation resin and the adhesive resin. A foil or paper coated with adhesive may be rolled on to a side of the stack of laminations to prevent separation before curing.
