Abstract: A drum-equipped apparatus for the wet treatment of batches of material has a horizontally oriented rotatably supported drum including a drum shell bounded by end walls and including a central inlet opening and a central outlet opening provided in the one and the other end wall, respectively. The apparatus further has a drive for selectively rotating the drum in a treating direction and in an opposite, conveying direction. A lifting wall is secured to the drum in the inside thereof for displacing the material batch radially with respect to the rotary axis of the drum during the rotation thereof in the treating direction. Further, a slide is secured to the drum in the inside thereof for displacing the material batch in the axial direction of the drum towards the outlet opening during the rotation thereof in the conveying direction. The drum is supported in an external vessel which receives treating liquid into which the drum is partially submerged.

Abstract: A drum-type machine for the treatment of batchwise textile material, especially a washing machine, with at least one drive drum rotatably supported in an approximately horizontal position having a central opening in one end wall for loading purposes and a central opening in the other wall for unloading purposes, as well as a conveying paddle in the interior for moving the batch of material about within the drum during rotation of the drum in a first direction and for the axial transporting of the batch of material through the unloading aperture in the other direction of rotation of the drum is provided with a sensor having a feeler oriented into the loading and/or unloading aperture, wherein the feeler is effected by the batch of material moving through the loading and/or unloading opening and acts to generate a signal if a part of the batch of material remains in the zone of the aperture after unloading.
