Abstract
A retention device for a tubular casing material for receiving a viscous or granular filling material in a packaging machine, in particular a clipping machine that has a filling tube for filling the tubular casing material with the filling material, where the retention device includes: a first brake ring, which can be mounted coaxially on the filling tube, the inner diameter of first brake ring being larger than the outer diameter of the filling tube and on the inner circumference of which a first brake 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. A second brake ring is also provided which can be stationarily disposed on the filling tube and which has a counter-brake on its outer circumference, where the casing material can be guided between the first brake of the first brake ring and the counter-brake of the second brake ring and where the first brake ring is reversibly displaceable in the filling direction for setting a predetermined friction force for the casing material at the first brake of the first brake ring and at the counter-brake of the second brake ring.
