Abstract
An apparatus for feeding mats to a press, e.g. for the production of particleboard or the like, comprises a feed conveyor with a discharge nose which lies in a plane tangent to the plane of a receiving conveyor entraining the mat into the press. Between the pick-up side of the receiving conveyor and the discharge end of the feed conveyor, this plane is tangent to a drum whereby press underlays are positioned beneath each mat with a head bar disposed ahead of the leading edge of the mat. According to the invention, the surface of the conveyor is provided with recesses to receive each bar so that the latter lies at least in part inwardly of the circumference or periphery of the drum while an underlay sheet lies along a drum surface which progressively merges with the circumference from this recess, i.e. is progressively asymptotic. When the recess is fixed, it can have a flank ahead of the bar against which the bar is positioned. When the surface is swingable to lift the bar out of the recess, the bar may be magnetically held on the movable portion defining the surface.
