ABSTRACT:
A spreading head is provided for a wafer sheet coating machine, which comprises a wafer sheet conveyor, which is optionally adapted to be lowered. The spreading head comprises a rotating spreading roller and a sizing device, which cooperates with said spreading roller to control the thickness of a layer of a spreadable composition as it is transferred by said spreading roller. The spreading roller and the sizing device define a lower boundary of a reservoir, which is adapted to hold said spreadable composition and which is laterally defined by platelike elements. To prevent an escape of spreadable composition from the reservoir along the end faces of the spreading roller, it is proposed to provide at least on each end face of the spreading roller a lateral covering, which extends from the reservoir for the spreadable composition along the periphery of the end face of the spreading roller continuously at least as far as to the point where the layer of the composition transferred is removed from the spreading roller. Said covering may be integral with the adjacent platelike element.
