Abstract
A method of controlling the press force on at least one press heating plate along the press length of an operating cycle. For a reduction of specific press force from a maximum press force towards a zero press force, a setting force for a longitudinal deformation of the at least one press heating plate is increased accordingly. For an increase in the specific press force from a zero press force towards a maximum press force, the setting force for the longitudinal deformation of the press heating plates is reduced accordingly. For a reduction of the specific press force from the maximum press force towards the zero press force, the longitudinal gradient tan .beta. is set to be approximately twice as large as the gradient tan .alpha. at the press force maximum. The longitudinal gradient and setting force can thus be controlled along an entire pressing path for an increase or decrease in the specific press force.
