To provide an in-line web-centering apparatus centering a web of a material in an aseptic internal area of a form-fill-seal and packaging machine.
This web centering apparatus comprises a support member 40, a tracking assembly 36, and an alignment mechanism 38. Each of them is stored in the internal aseptic area of the packaging machine. The support member 40 is integrally secured to the molding-filling-sealing and packaging machine. The tracking assembly is mounted on the support member 40, and swung around the support member. When the tracking assembly 36 is swung, it is positioned at a fixed angle relative to the support member 40. Consequently, when the alignment mechanism 38 is activated, the angle of the tracking assembly is modified to control the flow passage of the web of the material in the packaging machine.
