Abstract
A hot knife coater comprises a pair of thicknesser blades defining between them a thicknesser gap through which a web to be coated passes. Each blade is connected to a downwardly depending mid-portion of a blade support by means of a number of longitudinally spaced blade holders. This minimizes bowing of the blade supports as a result of heat conducted to the blade supports from the respective blades. The blade holders connecting one of the blades to the respective blade support are adjustable so as to permit local adjustment, in the region of each blade holder, of the gap. Each blade support is mounted so as to be pivotal about a longitudinally extending pivot axis and is biased by a spring against a stop. This permits automatic opening of the gap to let a seam in the web through the gap, thus eliminating the need for operator intervention.
