<p>Proposed is the trough unit in assembly (10), designed for delivery under an action of dead weight of separate drops of glass mass to be shaped which are at high temperature to the respective section of glass-forming machine to form container glassware. The trough unit in assembly has grooved element (12), which configuration in general corresponds by its shape in cross section thereof to the letter V directed with opening upwards, and collector (14), which is placed at least partially under the grooved element and has a configuration in the cross section which in general corresponds by its shape to the letter U, directed with opening upwards. The grooved element (12) inserted in the said collector has inlet opening (14a) for compressed air designed for receiving compressed air or that delivered by ventilator which is passed through the said collector being in contact with the said grooved element and providing necessary cooling which allows to cool the said grooved element and reduce in this way the friction coefficient between drops of glass mass passing along the said trough unit in assembly, and grooved element disposed therein.</p> |
