ABSTRACT:
A continuously operable press for the manufacture of laminates and similar products has a heated press roll, two guide rolls, and at least one tensioning roll. One end of the rolls is journaled in bearings at a fixed support wall and the other end of each roll is removably journaled in bearings of a movable support wall. A pressure belt is passing over the rolls, but a decorating roll sleeve can be slid on and of from the press roll, and this provides a decoration on the adjacent laminate surface. The press has a device for lifting the relaxed pressure belt so as to remove the decorating roll sleeve. The lifter device has at least two transverse lift bars with suction heads, and the lift bars are distributed about the upper circumferential region of the press roll. Compressed air can be introduced between the press roll and the decorating roll sleeve when taking the decorating roll sleeve from the press roll. The movable support wall comprises a clamping assembly for holding the decorating roll sleeve during removal from the press roll.
