<p>The method involves closing an angle between lateral edges of connection channels of sheet metal strips (12) continually when bending the sheet metal strips. The lateral edges are put together from outside to inside without a gap on impact in a direction, where an appropriate connection bridge is increasingly stretched. The radius of circular laminated cores (36) is accurately achieved by a complete form closure of the lateral edges with a recess/projection. Independent claims are also included for the following: (1) a rolling tool for implementing a method for manufacturing a circular laminated core for a rotor and/or a stator of an electrical rotary machine (2) a sheet metal strip for manufacturing a circular laminated core (3) a rotor or a stator manufactured with a sheet metal strip.</p> |
