ABSTRACT:
An apparatus for producing a foamed sheet of material has a mixing head mounted on a frame which is positioned on a track for longitudinal movement. The mounting head also engages a worm gear for vertical movement. Below the mixing head is a sloped portion of a conveyor. The sloped portion of the conveyor comprises a pair of stationary central panels and a right and left pair of panels. Each pair of panels is hinged together and slide toward and away from the longitudinal axis of the central panels. A paper sheet slides over the panels onto a level bottom conveyor. Vertical side fences are adjacent the side edges of the bottom conveyor panels. A paper sheet slides along the inside surface of each side fence at the same speed of the bottom sheet of paper. A worm gear adjusts the distance between the side fences. The sloped portion of the conveyor has a height adjustment mechanism at its upper and lower end and at the hinged portion of the panel. The central panels have air passages therethrough. A blower is operably connected to the air passages to blow air therethrough and under the paper sheet to glide the paper along the sloped conveyor.
