This device comprises a hollow calibrating pipe 2 having a central bore therethrough for mounting on the stuffing horn 1 of a stuffing machine, and an enlarged circumference 8 at one end thereof which applies a frictional force to the tubular casing 4 as the casing is drawn over the pipe during filling. At least the enlarged end 8 of the pipe 2, moreover, is made of a resilient material to provide this area with a variable circumference to eliminate damage to the casing due to variations in the size thereof. Means 3 are also provided for adjusting the effective circumference of the enlarged end 8 of the pipe 2. | |
