The membrane press exploits the vacuum principle and operates in such a way that an elastic membrane is "pulled" against the element to be pressed thus creating a vacuum in the part below. Each pressing system consists of a containment tank formed by a double electro-welded metallic frame, between the two frames and with a narrow support surface such as to create the bottom of the tank. The base and the peripheral band of the tank are covered by a non-stick film for quick and easy cleaning of any residual glue that may leak out during the pressing phases.
On the edge of the pressing tank there is a system with articulated lever type elements that lock and seal the membrane.
The lower subframe is provided with a mechanical levelling system that during installation of the same allows fine point to point adjustment that ensures millimetric flatness of the wooden elements obtained with the press.
The electric-electronic control system consists of a console-mounted control unit that collects the operation commands and monitoring tools that interface the work parameters during the various stages of work.
To speed up the work cycle, the vacuum pump is dual-stage: the first stage to ensure high flow rate and low vacuum in the initial stage of extraction, the second stage at a low flow rate and high vacuum value (up to 98%) at the maintenance phase, the total flow rate of the pump is approx. 150 m3/h, the force pressure of the membrane on the wood is 9800 kg/m2.
The internal usable dimensions of the tank or tanks are:
- Length: 14:40 m.
- Width: 3.38 m.
