Abstract
The centering and entrainment devices, by means of which the warp beam can be clamped or chucked, are axially slidably guided at side plates of the beam warping machine. With their outer ends they are hingedly connected at a respective lever. Both of the levers are pivotably mounted, by means of their one end about stationary pivot pins, in a plane which contains both of these pivot points as well as the axis of the warp beam. At their opposite ends both of the levers are interconnected by a rod arrangement, wherein a threaded sleeve having two opposite internal threads and rotatably mounted in one side plate allows changes in the length of such rod arrangement. Consequently, both of the levers can be synchronously and axially symmetrically moved towards and away from one another, so that the coaxially guided centering and entrainment devices can be symmetrically advanced towards and displaced out of the warp beam.
