Abstract

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 conv…
