casing with a fresh casing section that is to be filled during the next operating cycle the twisting device is deactivated and comes to a standstill after a short deceleration phase simultaneously with the deactivation of the twisting device the conveyor screw is again energized at point a 39 and it goes through the next operating cycle a 39 b 39 c 39 d 39 the cycle interval t 1 from the start of a complete operating cycle to the start of the next complete cycle may be decreased by overlapping of the filling steps or intervals 23 with the separation intervals 24 the cycle interval t 1 and the pause time t 4 from the standstill of an operating interval to the commencement of the next operating interval can be selected the same applies to the rates of rotation fig2 shows a first embodiment of the apparatus constructed in accordance with the invention for dispensing a sausage material into a tubular casing a conveyor pump 2 has two cooperating conveyor screws 3 and is intermittently coupled to a continuously operating drive via an electromagnetically actuated coupling 4 during the filling steps the pump conveys a sausage material into a tubular casing which is mounted over an output spout of the pump the sausage mass is dispensed into the tubular casing in portions of the desired volume a twisting.
