Abstract: A cloth stuffing chamber or container, preferably a tube with entrance and exit portions, is provided with means for preventing backward movement of the cloth. This means is preferably in the form of a fixed ring at the beginning of the exit portion having around its inner surface at least several segments of wire which are slanted toward the exit portion of the tube. There is provided between the entrance and fixed ring a movable ring with wires or pins also slanting in the same exit direction, which ring is reciprocated by a drive, such as a cam and follower. Cloth is introduced into the entrance portion of the chamber and passes through the two rings, and as the movable ring reciprocates, its slanted wires move the cloth forward on the forward stroke and on the reverse stroke the slanted pins of the fixed ring prevent the cloth from moving backwards.
