Abstract

A reed in a loom is driven or oscillated back and forth to perform the beat-up motion by a direct reed drive that avoids using the main loom drive for operating the reed. The direct drive is an electromagnetic motor which uses as one of its components a reed support shaft (4) either as a rotor or as a stator. The reed support shaft acting as a rotor carries a reed slay which mounts the reed to the rotor. When the reed support shaft acts as a stator, the reed slay is mounted to separate rotor elements. In both instances the reed support shaft is part of a rotary or linear electromagnetic direct drive motor construction.
