System for controlling the sizing of a rising foam emulsion web travelling on a conveyor

A system for controlling the sizing of a rising foam emulsion web travelling on a conveyor, the system comprising:

• a plate arrangement comprising a plurality of plates, the plurality of plates comprising at least a first plate and a second plate, each plate of the plurality of plates having a web-facing lower side that is configured to contact the rising foam emulsion web and an opposite upper side, wherein the second plate is configured to be located downstream of the first plate with respect to the direction of travel of the foam emulsion web;
• and
• an actuating arrangement comprising a base portion and a top portion, the top portion being movable relative to the base portion and being operatively connected to the plate arrangement, the actuating arrangement being configured to individually set for each plate of the plurality of plates of the plate arrangement a fixed separating distance between the web-facing lower side configured to contact the rising foam emulsion web and the base portion for controlling the rising of the foam emulsion web along at least a part of its travel.
