Abstract

A slot closure for the semi-closed slots of the stator of an electric machine is disclosed. The slot closure comprises slot closing bars interconnected in a ladder-like arrangement by flexible strips. Flexing of the strips by about 90.degree. correspondingly rotates individual bars and permits them to be successively inserted edge-wise through the slot openings. Advantageously, the ladder-like arrangement of bars and strips is made of a moldable or stampable material.
