Device and method for detecting material properties of a packaging material web, preferably in a packaging machine and packaging machine

摘要

The invention relates to a device (10) for detecting material properties of a packaging material web (5), in particular in a packaging machine (100), having a sensor device (20) which is designed for friction coefficients (μ) or a web tension (S) of the packaging material web (5), wherein the sensor device (20) is arranged in the region of a first deflection device (21) for the packaging material web (5). According to the invention, provision is made for a device (25) for feeding and forwarding the packaging material web (5) to and from the first deflecting device (21), which is designed to fix the packaging material web (5) in a first operating state and a second operating state, the packaging material web (5) preferably to lead friction, and that the sensor device (20) is adapted to both friction (μ) and web tension (S) of the packaging material web (5) to detect.
