Closed Loop Feedback Press

The pressing of an article is achieved with a closed-loop feedback press. The closed-loop feedback press is effective to measure an amount of pressure applied and adjust the pressure to achieve a prescribed amount of compression on the article. Further, the press may leverage a closed-loop feedback system to maintain a consistent temperature of one or more platens. The press is able to adjust a pressure applied one or more times during a pressing operation to accelerate a temperature change in the pressed article while reducing the pressure applied as the temperature approaches a target temperature to limit unintentional deformation and bleeding of the pressed material of the article.

20170312966 · 2017-11-02 ·

The smoothing device for plastic films comprises plastic-melt-producing means (1, 5), an adjustable slit die (10) and a roller smoothing unit (16) having cooled smoothing rollers (11, 12), which form an adjustable smoothing gap (13) between each other. Optionally, further rollers (15) are arranged downstream. A thickness gauge (23) measures the thickness of the plastic-film web (22). A controller (30) for controlling the thickness of the plastic-film web (22) may set a setpoint thickness (SD) of the plastic-film web (22) and the volumetric flow rate (SS) of the plastic melt or the line speed (LS). The controller (30) captures the current torques and rotational speeds of the rollers (11, 12, 15) and the current thickness (FD, FD1-FDn) of the plastic-film web (22).

The controller (30) sends setpoint rotational speed signals (C0S, C2S-CnS, CAS) calculated from the captured torques of the rollers (11, 12, 15) to the drives of the rollers and a smoothing-gap setpoint distance signal (GW) for adjusting the smoothing gap (13), and furthermore—in the case of a specified line speed (LS)—setpoint plastic-melt volumetric flow rate signals (SS) to the plastic-melt-producing means, or—in the case of a specified plastic-melt volumetric flow rate (SS)—setpoint line speed signals (LS) to the drives of the rollers (12).

INSULATION COMPACTION DEVICE AND METHOD FOR FORMING AN INSULATED STRUCTURE FOR AN APPLIANCE

An insulation compaction device includes an insulating structure of an appliance and has an insulating media disposed within an insulating cavity. An operable piston selectively engages the insulating structure and operates to define a selected cavity volume of the insulating cavity and a selected insulation density of the insulating media. A valve is attached to the insulating structure and in a passive state releases gas from the insulating cavity to the exterior during operation of the operable piston. Selective operation of a pump mechanism places the valve in an active state to extract gas from the insulating cavity and define a cavity pressure of the insulating cavity that is less than an equalized pressure. The operable piston and the pump mechanism are at least one of sequentially and simultaneously operable to define a selected piston chamber environment defined by the selected cavity volume and the cavity pressure.
