ABSTRACT:
A veneer dehydrating apparatus is disclosed. The apparatus includes a pair of rolls disposed so as to form a nip between the peripheries thereof through which a green veneer sheet is passed. At least one of the rolls has on its periphery a number of tooth-like projections separated from one another by grooves formed on the roll periphery. Each projection is pierceable into a veneer sheet to squeeze out part of water contained in the veneer sheet by compression exerted thereto by the projection piercing thereinto. The toothed roll has an elastic filler member fitted round the roll so as to fill the spaces between the projection. The elastic filler member comprises an elastic portion made of, e.g., sponge rubber and a reinforcement portion made of, e.g., fabric and secured to one surface of the elastic portion and seated firmly against the radially innermost surface of the grooves.
