Carton top sealer apparatus and method |
摘要 |
A method for forming a top seal on a carton being conveyed along a processing path on a form, fill and seal packaging machine using a top sealer including opposing sealing jaws is provided. The carton includes top fin panels configured for sealing to one another to form a top seal. The method includes actuating a first control valve to provide communication between a first pressurized fluid source and a first port of an actuator for moving the actuator toward a first position. The actuator is operatively connected to the sealing jaws to move the sealing jaws in a clamping direction while moving toward the first position. A second control valve is actuated to inhibit fluid escape from the actuator through a second port of the actuator to inhibit movement of the sealing jaws in the clamping direction.
