Estimating the term…
A double belt press having a first, lower circulating plastic belt and a second, upper circulating plastic belt. The plastic belts have a first, low flexural strength, and a product gap is formed between facing strands of the plastic belts for forming a plate-like product. A first circulating lower steel belt and a second circulating upper steel belt are provided and have a second flexural strength which is high in comparison to the flexural strength of the plastic belts. A forming section is formed between the facing strands of the steel belts, which forms part of the product gap. The first, lower steel belt runs parallel and bears against a rear face of the first plastic belt in the forming section during operation, and the second upper steel belt runs parallel and bears against a rear face of the second plastic belt in the forming section during operation.
A double belt press with a first, lower revolving plastic belt and with a second, upper revolving plastic belt, the plastic belts having a first, low flexural rigidity, and a product gap between the mutually confronting strands of the plastic belts being formed for the purpose of shaping a plate-like product, a first revolving lower steel belt and a second revolving upper steel belt, the steel belts having a second flexural rigidity which is high in relation to the flexural rigidity of the plastic belts, a shaping portion being formed between the mutually confronting strands of the steel belts, the shaping portion forming part of the product gap, during operation the first, lower steel belt running in the shaping portion parallel to and so as to bear against a rear side, facing away from the product gap, of the first plastic belt, and during operation the second, upper steel belt running in the shaping portion parallel to and so as to bear against a rear side, facing away from the product gap, of the second plastic belt.
A method for producing a plate-like product using a double belt press, comprising the steps:
