Weaving machine having separable parts with constrained guidance upon assembly and re-assembly

A weaving machine, comprising a stationary first machine-frame part containing at least means for winding up a woven material and as second machine-frame part removable from the first part and containing at least means including a bearing for supporting a warp beam when the second machine-frame part is re-assembled to the first machine-frame part, the improvement wherein the stationary and removable machine-frame parts include mutually engaging guide means including a first guide element fixed to said first machine-frame part and a second guide element fixed to the second machine-frame part for constraining movement of the removable part to a predetermined path upon engagement between said guide elements during re-assembly with or removal from the stationary part, and wherein the removable machine-frame part comprises arms extending away from the bearing of the warp beam, the arms supporting a harness guide.
