Abstract

The shed formed by the warp threads in a loom is changeable by a shed drive that may either be an eccentric drive or a shaft drive. In order to rapidly exchange one shed drive (2) by another shed drive (3) these shed drives are mounted individually in a respective carriage (4). The carriage is constructed for docking in an exchange position next to the loom. An empty first carriage can take up a shed drive currently cooperating with the loom to remove the shed drive from the loom. A second carriage carrying another shed drive can then dock in the exchange position after the second carriage has been removed. The carriage is positionable either manually or automatically in response to distance signals.
