(54) Device for controlling the distance between a glueing cylinder and a corrugating roller for a cardboard corrugating machine


(57) The machine for the production of corrugated cardboard comprises:
  • a first corrugating roller (7);
  • a second corrugating roller (9) co-operating with the first corrugating roller for corrugating a sheet of web-like material (N), which passes between said first corrugating roller and said second corrugating roller, which are provided with projections that mesh together;
  • a gluing assembly (31) with a gluing cylinder (41), which co-operates with the first corrugating roller for applying a glue on the crests of said web-like material; and
  • adjustment means for adjusting the position of the gluing cylinder with respect to the first corrugating roller.

The adjustment means comprise a detector for detecting an angular displacement between the gluing cylinder and a wheel for transmitting motion to the cylinder. The position of the gluing cylinder with respect to the corrugating roller is adjusted according to said angular displacement.
