Abstract
An apparatus and method for effecting a warp change in weaving machines involves clamping the warp yarns of a new warp on a tying-in frame by way of clamping members. In addition, the warp yarns of the woven-out warp, the end portion of which has previously been pulled forwards over a specific length, are lifted over the tying-in frame and laid onto a roller assigned to the clamping members. The warp yarns of the woven-out warp are then fixed on the roller and pulled back out of the weaving machine over the specific length as a result of the rotation of this roller. These operations can be carried out by a single person, so that the warp change is simplified substantially. The tying-in frame and roller are mounted on a common carrier which is mountable on a warp-beam transport unit.
