Abstract: A method establishes rheometric parameters of samples using a rotational rheometer. A thickness of a measurement gap delimited by measurement parts is measured by a measuring unit and a predetermined thickness value is adjusted, readjusted or kept constant when the measurement temperature is changed or set to a predetermined measurement temperature setpoint value. Accordingly, starting at a time at which at least one region of a measurement part has reached the predetermined measurement temperature, measurement values to be established, more particularly continuously, at predetermined measurement times and/or for predetermined time intervals delimited by predetermined measurement times, for the changing thickness of the measurement gap and/or for the rate of change in thickness or readjustment of thickness, and for the measurement of the rheological parameters only to be commenced once these measurement values have dropped below a specific predetermined threshold.

Abstract: The invention relates to a dispersion installation for dispersing dispersible material on a dispersing material conveyor belt so as to form groups of material for producing wood-material boards. Said system comprises at least one dispersion material bunker for the dispersible material dispersed on the dispersing material conveyor belt, having at least one top side filling opening. A chute is connected to the filling opening via which the dispersible material can enter into the dispersion material bunker. The invention is characterized in that at least one brake cylinder device is arranged inside the chute, said brake cylinder comprising at least two rotationally driven brake cylinders.

Abstract: The invention relates to a frame press having a plurality of press frames (1) arranged one after the other, wherein at least one stationary press plate (2) is present and furthermore a press plate (2) is provided which is loaded by means of working cylinder piston arrangements (3) and which can be moved against the stationary press plate (2). On two opposite outer sides (8) of the press, at least two guide columns (5) arranged at a distance to each other are provided, respectively, and each guide column (5) is guided through at least one associated guide opening or through at least one associated guide channel (6) when the press plate (4) which can be moved is moved.

Abstract: A press for crimping longitudinal edges of a plate for the manufacture of pipe has a closed press frame, an upper press platen, and a lower press platen extending longitudinally through the frame. A pair of transversely spaced and transversely shiftable upper supports are provided on the upper platen, and a pair of transversely spaced and transversely shiftable lower supports on the lower platen. Respective upper dies are fixed in the upper supports and have downwardly directed lower faces, and respective lower dies are fixed in the lower supports and have upwardly directed upper faces. A piston/cylinder assembly braced between the frame and one of the platens and pressurizable to shift the one platen vertically toward the other of the platens. Hydraulic actuators may position the holders and their dies transversely and also lock them in place.

Abstract: A panel press has horizontally spaced and vertically oriented window-type tension frames each in turn having an upper beam having opposite ends each formed with an upwardly directed seat, a lower beam beneath the upper beam and having opposite ends each formed with a downwardly directed seat, and respective vertical side elements extending between the ends of the upper and lower beams and each unitarily formed with a laterally projecting upper end having a downwardly directed surface bearing downward on the respective upper-beam seat and with a laterally projecting lower end having an upwardly directed surface bearing upward on the respective lower-beam seat. Vertical bolts secure the laterally projecting ends to the respective beam ends.

Abstract: A press has at least two rigid and generally planar platens normally brought together to hot-press a panel workpiece. Each platen is formed with a plurality of parallel longitudinally throughgoing bores having ends open at edges of the platen, an array of orifices opening at at least one face of the platen and communicating with the bores between the ends thereof, at least one manifold passage extending transversely in the platen adjacent at least one of the edges and intersecting the bores, and a heat-exchange passage offset from the bores and manifold passage. A heat-exchange liquid is passed through the heat-exchange passages. The ends of the bores are closed, and a treatment vapor is injected under superatmospheric pressure into or withdrawn by subatmospheric pressure from the manifold passages so as to expel the vapor from the platens via the orifices or suck vapor from the platens in through the orifices.
