Abstract
The invention includes an arrangement for manufacturing an elongated object (4) including, inter alia, a fibrous material, by compressing (7,8) a quantity of fibrous material provided with a binding agent and drying the compressed fibrous material by passing the material between the electrodes of a high-frequency drier (5). One electrode (12), preferably both electrodes (12, 13) of the drier is/are arranged to co-act with an electrode-heating device (16).
Claims6
An apparatus for drying an elongated fibrous object, comprising:
- a drying chamber;
- two electrodes mounted inside the drying chamber, said electrodes being arranged substantially parallel to each other and separated by a space for containing and drying the fibrous object;
- two electrically insulating rods, arranged between the electrodes with one rod on each side of the space, for compressing two sides of the fibrous object;
- and
- means for raising a temperature of at least one of the electrodes to a temperature at which vapors produced by drying the fibrous object will not condense on said one electrode;
- wherein said temperature raising means also raises the temperature of every surface inside said drying chamber to a temperature at which vapors produced by drying said fibrous object will not condense on any surface inside said drying chamber.
