An apparatus for processing a consolidated stack of fiber reinforced plies, comprising an inspection device, in particular an optical inspection device, arranged to inspect a consolidation state of the stack of fiber reinforced plies, and a handling device arranged to make at least an outer surface of the stack of fiber reinforced plies available for inspection by the inspection device.

An ellipsometry system detects and/or identifies significant corrosion on glass, such as on soda-lime-silica based float glass. In certain example embodiments, there is provided a method and/or system using ellipsometry to detect and/or identify significant corrosion on soda-lime-silica based glass, so that such significantly corroded glass can be identified and not coated with a low-E coating and/or not used in applications where optical appearance is important. The ellipsometry system may be part of, or used in connection with, a sputtering apparatus/system for sputter-depositing low-E coatings on glass, so that whether to pass a piece of glass to the sputtering apparatus/system is based on whether significant corrosion is detected on the glass.

A backing member (50a) is pressed in a perpendicular direction (D3) by a predetermined sheet conveyed to a colorimetric position (P), and is disposed behind the predetermined sheet at the colorimetric position (P) when viewed from a colorimetric unit (40). A supporter (90) supports the backing member (50a) in a manner that the backing member (50a) can move in the perpendicular direction (D3). Holders (23a, 23b, 23c) hold a color tile member (80a) disposed on the backing member (50a) in a state that the amount of movement of the backing member (50a) in the perpendicular direction (D3) by the color tile member (80a) being thicker than the predetermined sheet and disposed on the backing member (50a) is larger than the amount of movement of the backing member (50a) in the perpendicular direction (D3) by the predetermined sheet.

A method for calendering an electrode tape via a calendering process, in which an electrode tape is passed through a roller gap of a pair of rollers of a calendering device, namely by compressing the electrode tape. During the calendering process a defect detection step is carried out, in which at least one defect of the electrode tape is directly or indirectly detected. If a defect is detected during the defect detection step, the pair of rollers is adjusted from a calendering position of the pair of rollers to an open position of the pair of rollers in an opening step, and this is before the defect reaches the roller gap. The defect detection step and/or the opening step is carried out, preferably automatically or fully automatically, via an open-loop and/or closed-loop control system of the calendering device.

A moisture sensor detects moisture in an object. A first light-emitting element emits light. A first reflecting member reflects light reflected from the object toward the object. A light-receiving element receives light that is multiple reflected between the object and the first reflecting member. A controller determines an amount of moisture in the object based on a light reception result from the light-receiving element.
