Pouch machine includes infeed section, sealing section, outfeed section. Sealing section Includes at least one sealer that has a sealing fixture disposed to move in a first direction toward and away from a sealing position. A linear actuator provides a controlled motion in a second direction, not the first direction. A linkage is connected between the linear actuator and the sealing fixture. The linkage translates the motion of the actuator into controlled motion of the sealer. The linkage multiplies force when the sealer is in the sealing position, and multiplies distance/velocity when the sealer is retracted. Sealing fixture includes a die backing having at least one clip mounted on it. The clip includes a hook end, a first relaxed position and second tension position. Sealing die includes a receiver that receives the hook end. When the clip is in the tension position, sealing die is held against die backing member. |
