  • Publication number: 20240009948
    Abstract: A continuous press arrangement for manufacture of building panels, such as floor or wall panels, includes upper and lower press belts configured to form a product path therebetween for feeding a product in a feeding direction in response to rotation of one or more drums. An upper and a lower press table each include a displaceable pressure cushion configured to facilitate a pressure zone extending along at least a portion of said path. At least one of the press tables includes one or more pressure bars disposed upstream and/or downstream the pressure cushion, in the feeding direction. The one or more pressure bars are configured to apply a pressure to the upper press belt and/or the lower press belt respectively in a direction towards the product path.

  • Publication number: 20240009886
    Abstract: A continuous press arrangement for manufacture of building panels, such as floor or wall panels, comprises an upper rotatable inlet drum connecting to an upper rotatable outlet drum via an upper continuous press belt and a lower rotatable inlet drum connecting to a lower rotatable outlet drum via a lower continuous press belt. The press belts are configured to form a product path therebetween for feeding a product in a feeding direction in response to rotation of said drums or displacement of the press belt(s). An upper and a lower press table each comprise a cushion configured to be displaced into sealing abutment with the press belt for facilitating a pressure zone. The inlet drums form respective angles phi between the respective press belts and the product path at a position being downstream the inlet drums and upstream the pressure cushion or press table, in the feeding direction.
