A press for pressing a mat into a thin panel has a press frame, upper and lower press plates on the frame, and upper and lower press belts having confronting lower and upper stretches defining a press gap extending in a horizontal and longitudinal transport direction and respectively running below and above the upper and lower press plates. Upper and lower flexible intake plates are juxtaposed respectively above and below upstream ends of the lower and upper stretches of the belts and define therewith a downstream portion of an intake mouth flaring upstream. Upper and lower rollers are respectively braced against the upper and lower stretches of the belts at an upstream portion of the intake mouth immediately upstream of the downstream portion of the intake mouth. Further actuators connected to the rollers set a shape of the upstream portion of the intake mouth.

Continuous belt-type board press

Particulate mats are transported from the downstream end of an upstream conveyor normally moving continuously in a longitudinal transport direction at a predetermined relatively slow speed to a press downstream in the direction from the upstream conveyor that receives the mats and presses them into hard panels by supporting the mats between the upstream conveyor and the press on a downstream conveyor having an upstream end spaced downstream from the downstream end and a downstream end at the press and an intermediate conveyor extending between the upstream end of the downstream conveyor and the downstream end of the upstream conveyor and having a length in the direction at least equal to that of each of the mats in the direction. A carriage supporting the downstream end of the upstream conveyor, the intermediate conveyor, and the upstream end of the downstream conveyor is reciprocated in the direction at a frequency related to mat size and speed. The upstream conveyor moves generally only at a first relatively slow transport speed in the direction and the downstream conveyor moves generally always at a substantially higher transport speed in the direction, but the intermediate conveyor moves at the slow speed when a mat is bridging it and the upstream conveyor and at the higher speed when a mat is bridging it and the downstream conveyor.

Method of conveying particulate mats

Conveyor for particleboard-making apparatus

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.
