Abstract:
1. A method of controlled closure of at least one clip around a filling material-free plait portion of a tubular casing at a filling material portion enclosed by the casing, wherein the at least one clip is closed with at least one closure device and wherein successive filling material portions are filled with a moved product flow with the filling material and in that operation the casing is withdrawn from a casing supply, the method comprising the steps of: sensing the withdrawal movement of the casing between two successive closure operations over at least one of a short period of time and a short length portion; and forming a control signal based on the sensed withdrawal movement therefrom; and controlling the joint movement of the at least one closure device with the product flow of the filling material when filling the respective filling material portion based on the control signal by moving the closure device at least in a direction approximately parallel to the direction of movement of the product flow; and closing the clip around the filling material-free plait portion during said joint movement.
