Abstract
A slot-closing device for closing a slot in a stator or a rotor of an electric machine includes a closure element for closing the slot. A closure element for closing the slot contains a ferromagnetic material, and has a predetermined bending section along a longitudinal extension direction of the closure element, such that two leg portions disposed at an obtuse angle of less than 180° to one another are connected by the bending section. An adhesive layer designed to harden when heated is disposed on edges of the two leg portions.
