Patent attributes
A packaging and filling apparatus fills a tube of a web of a packaging material with a fluid product, forms lateral seal bands, cuts each seal band of a series of pillow-like preformed bodies with a cutting device to form a packaging and filling container of the final form. The cutting device comprises a resistance measuring device for measuring a cutting resistance pressure that a packaging material cutting blade receives from the packaging material, and then outputting a measurement value obtained, and a blade monitoring device for monitoring the condition of the packaging material cutting blade based upon based upon a comparison of a difference between a maximum measured cutting resistance pressure and a constant measured cutting resistance pressure following the maximum measured cutting resistance pressure with a predetermined pressure difference reference value.
