Definitions

  • the invention relates to a method for winding paper or cardboard webs on winding tubes and a winding machine for performing the method.
  • EP 0 481 029 B1 describes a winding machine in which the entire Roll weight is carried by the guide heads.
  • the winding rolls are from the side with the desired line force pressed against the support roller.
  • the guide heads are equipped with rotary drives.
  • a backing roll winding machine is known from EP 0 629 172 B1, in which the Winding stations are arranged on both sides next to the apex line of the backup roller.
  • the Back-up roll bears the entire roll weight at the start of winding. If that Roll weight for the desired line force from a certain winding roll diameter becomes too big, the leaders take on a bigger and bigger size increasing proportion of the roll weight.
  • DE utility model 296 15 385 describes a roller for a winding machine, which has a hollow cylindrical support body made of a solid material whose jacket is a deformable layer is applied, which consists of a cellular Plastic material with a large number of evenly distributed pores and that has a compression modulus ⁇ of less than 10 MPa. It is stated that such a roller advantageously as a backup roller in a backup roller winding machine can be used because it almost eliminates nip-induced stretching of the web.
