Title: Initial press, used in board production
Inventor: SCHMIDT HEINZ DIPL ING
IPC: B30B5/06
Filed: 1998-05-15
Granted: 1999-08-12
Abstract: The pressure roller is on a spring mounting against the mat as it is carried through. Press is used in the continuous pressing of a mat of wood particles, into boards. The wood particles are spread on to a flexible sieve surface to form the mat to be transferred continuously to the pressure roller of an initial press for compression, before the main press for pressing the board materials. The pressure roller is on a spring mounting against the mat as it is carried through, to be displaced against the spring pressure across the mat plane by the moving mat or any foreign body moving with the mat.  The spring pressure is adjustable at the pressure roller so that it is displaced from a carried foreign body on breaching the linear pressure set for a normal press action, without damage to the press.  The spring pressures are set at different levels in the successive press rollers, in the direction of mat travel. The successive press rollers give an initial compression to the mat material to give a blank which is transferred to a further press for compression into the board material together with heat.  An Independent claim is also included for a double belt press assembly with two continuous shaping belts (1, 2) round deflecting guide drums (4, 6, 8, 8'), to carry the board material on the sieve underlay between them through the press section.  At least one pressure roller (14, 14') forms a gap with a counter roller (15, 15') at the press stretch, to compress the mat material moving through continuously. The pressure roller (14, 14') is on a spring mounting, to be moved away from the material against the spring pressure by a carrier at the sieve underlay or a foreign body carried with the material.  Preferred Features: The counter roller (15, 15') is on a rigid mounting at a common support structure (26, 28), to give an adjustable gap between it and the facing sprung pressure roller (14, 14'). Two or more separate sprung pressure rollers (14, 14') have the same or different pressure, in succession in the direction of material movement, with adjustable and/or controlled spring pressures to give the required linear pressures between the minimum value and a level at least five times the minimum value. The pressure roller (14, 14') rotates on a rocker (20), against a spring for the pressure on the roller. The spring (23) can swing away from the material mat, using a hydraulic or metal spring (23). One belt deflection drum (6) for one belt (1) is on a spring mounting, against the pressure roller which is moved away from the mat, for compression. The sprung pressure roller (14, 14') can be pressed away across the mat plane against the spring (23) pressure by \- 10 mm (10-40 mm).

Title: Mounting of swimming roll which runs on individually adjustable hydrostatic bearings across its width for deflection control
Inventor: HAAG ROLF VAN DR ING
IPC: B21B13/14
Filed: 1998-05-26
Granted: 1999-07-29
Abstract: The stationary central support has bearings (7) at each end which between them provide the reactive force to the forces exerted by the roll. The force is set by the pressure PK exerted on the supporting hydraulic piston (8). Between the piston (8) and the bearing (7) is a surface (12) forming a gap (15) with a pocket (13) to give automatic compensation. The pocket (13) is supplied with hydraulic fluid through a flow restriction (16). If the load on one end of the roll changes slightly due to an adjustment of the roll pressure distribution, the size (s) of the gap (15) changes to change the flow rate and produce the correct supporting pressure in the pocket (13). The fluid flowing through the gap (15) is collected to a drain (19) and returned to the pump (17).
