Abstract:
1. A retention device for a tubular casing material for receiving a viscous or granular filling material in a packaging machine having a filling tube for filling the tubular casing material with the filling material, the retention device comprising: a first brake ring coaxially about the filling tube, an inner diameter of said brake ring being larger than an outer diameter of the filling tube, and on the inner circumference of the first brake ring a first brake device is provided, along which the casing material can be guided in the filling direction of the filling material against a friction force acting upon the casing material; and a second brake ring coaxially about the filling tube and having a counter-brake device on an outer circumference thereof, wherein the casing material can be guided between the first brake device of the first brake ring and the counter-brake device of the second brake ring, and the first brake ring being reversibly displaceable along the filling direction for setting a predetermined friction force for the casing material at the first brake device of the first brake ring and at the counter-brake device of the second brake ring.
