System and method for forming a compostable pod for beverages from a sheet having a controlled moisture level

Abstract

The invention relates to a system () for manufacturing a compostable pod () for brewing products. Therein, the pod () is made from a sheet () made of a biodegradable cellulose-based material. The system () comprises at least one shaping line (), which comprises a handling unit () for transferring the sheet () along a transfer direction (TD) through the system (). The shaping line () further comprises a humidifying unit () for moistening at least one side of the sheet () with a moistening agent (), and a forming unit () for shaping a part of the moistened sheet () into a three-dimensional shape to form a pod element (), which defines a pod cavity (). The shaping line () comprises further a humidity sensor system () for visually sensing a level of humidity of at least a section of the moistened sheet (). Values related to the level of humidity sensed by the humidity sensor system () are received by a control unit (), which is further configured to control the humidifying unit () based on these values. The invention also relates to a method for manufacturing a compostable pod (), whereby a level of humidity of at least a section of the moistened sheet () is visually sensed and forwarded for controlling the moistening process of the at least one side of the sheet () correspondingly.
