Abstract
A method of and an apparatus for 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, where the at least one clip is closed with at least one closure device and where the filling material portion is successively filled with a moved product flow of the filling material and in that operation the casing is withdrawn from a casing supply device, and where moreover the withdrawal movement of the casing is sensed with a sensing device and a control signal is formed therefrom for the joint movement of the at least one closure device with the product flow.
Claims13
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material portions are filled with a moved product flow with the filling material and in that operation the casing is withdrawn from a casing supply, the method comprising the steps of: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.
An apparatus for controlled closure of at least one clip around a filling material-free plait portion of a tubular casing at the end of a filling material portion enclosed by the casing comprising a closure device which closes the at least one clip in embracing relationship with the plait portion and a casing supply device from which the casing is withdrawn when filling successive filling material portions with a moved product flow of the filling material, the apparatus comprising:
- a sensing device capable of sensing the withdrawal movement of the casing out of the casing supply device between two successive closure operations over at least one of a short period of time and a short length portion and capable of forming a corresponding sensing signal;
- a controller capable of forming a control signal from the sensing signal operatively connected to the sensing device;
- the closure device being connected to a drive device for jointly moving the closure device in substantially parallel relationship with the advance movement of the product flow controlled by the control signal.
