Abstract

The invention relates to a process for adjusting the alignment of circulating press bands in a continuously operating press and a press adapted to permit such alignment.
The press comprises a press bed and a press top, a pair of flexible steel bands defining a press gap therebetween and circulating about said press bed and press top around drive and deflection rollers associated with said press bed and said press top, said press gap including a high pressure zone.
The flexible steel bands are aligned by horizontally pivoting the press top and the associated drive and deflection rollers through an angle .alpha. about a central vertical axis while temporarily reducing the pressure in the high pressure zone.
The press permits this pivoting by supporting the press top on pivoted support rods capable of parallelogram style movement.
