- A pressing arrangement as claimed in Claim 1, 2, or 3, CHARACTERIZED in that said counter body constitutes a stationary glide body (9).
- A pressing arrangement as claimed in anyone of the above claims, CHARACTERIZED in that the moving belt (5) is guided into the press zone (7) via the press roll (1) thus providing a preheating zone (8) prior to the press zone (7).
- A pressing arrangement as claimed in Claim 6, CHARACTERIZED in that the moving belt (5) is guided into the press zone (7) via the press roll (1) by means of a guide roll (16).
- A pressing arrangement as claimed in Claim 6, CHARACTERIZED in that the length of the preheating zone (8) is adjustable.
- A pressing arrangement as claimed in Claim 7 and Claim 8, CHARACTERIZED in that the length of the preheating zone (8) is adjusted by means of the guide roll (16).
