Apparatus for removing debris from path of moving fibrous sheet, e.g. in papermaking machine, comprising tiltable guide plates forming sliding path to receiver for debris from torn sheet
Apparatus (3) for removing debris from the path of a moving fibrous sheet (2) in a sheet production machine comprises at least two guide plates (3.1, 3.2) extending across the width of the machine, together forming a sliding path for the debris and directing debris from a torn sheet into a receiver below the path of the sheet. The upper plate (3.1) is telescopically displaceable relative and parallel to lower plate (3.2), and the plates are tiltable about a horizontal axis (3.4) transverse to the direction of motion of the sheet. An independent claim is included for a variant of the apparatus, in which the two guide plates are replaced by a single guide plate supported from underneath by a carrier device and movable up and down, the apparatus being tiltable about a horizontal axis transverse to the direction of motion of the sheet.
