Abstract
A warp beam lifting carriage for removing an empty warp beam from a loom or for inserting a full warp beam into a loom, is equipped with positioning devices that permit a precise positioning of the carriage in the three directions of space. An insertion stop mechanism limits the movement of the carriage toward the loom. A lateral restraining device makes sure that the carriage is horizontally centered relative to the loom in a direction perpendicularly to the movement direction toward the loom. A third leveling device makes sure that the longitudinal axis of the warp beam shaft can be precisely aligned with the horizontal axis of floating axle stubs that are inserted through bearings into sockets at the free ends of the wrap beam shaft. The precise alignment is quickly achieved and increases the productivity of the loom.
