Definitions

  • DE-PS 2 147 322 describes the production of a heat-sealable paper which weighs between 14 and 17 g / m 2 and in which the heat-sealable fibers or particles are preferably concentrated on one side of the paper surface. However, if the heat-sealable layer is preferably only on one side of the paper and then melted on the paper machine during the drying process, it closes off the porous base layer and prevents good tea diffusion.
  • Fig. 1b shows how through the described sharp drainage of the two layers, in particular the second layer with the fibers 2, penetration of the two layers is achieved, so that the synthetic fibers 2 get between the natural fibers 1 and from the top of the first layer down to the bottom between the natural fibers 1.
  • the suspension A is passed onto the sieve 5 via the first two dewatering chambers 6 via suitable pipelines and pump devices, which are not shown in more detail, the water being sucked off through the chambers 6 and the dewatering line a.
  • a first fiber layer of natural fibers 1 is formed on the moving sieve 5.
  • the second suspension B is supplied, a second layer of synthetic fibers being deposited over the dewatering chambers 7 on the first layer .
  • the drainage takes place via the drainage line b.
  • the screen 5 with the two fiber layers lying one on top of the other moves sharply through the dewatering chambers 8, the two layers penetrate one another. The penetration can be achieved more or less by adjusting the drainage accordingly.
