Grid adjustment


The grid can be in one, two or three parts. Correspondingly, it can be adjusted only as a unit or in individual sections.

Three basic adjustments are possible:

  • distance of the complete grid from the beater;
  • width of the gaps between the bars (Fig. 28, a=closed, b=open);
  • setting angle relative to the beater envelope (Fig. 27 and Fig. 28c).

It is not common to make all these three adjustments. In most the cases the machines are so designed that only two adjustment types are possible.
