<p>Apparatus for feeding liquid adhesive to a nozzle applicator composed of a degasifying device, which expels the gas bubbles from the liquid adhesive, and which consists of a narrow horizontal slit to which the liquid adhesive under pressure is fed. The horizontal slit opens at the interior of a gastight buffer chamber into which there are discharged the degasified liquid adhesive and the gases expelled from the liquid adhesive. The bottom of the gas-tight chamber is connected to the nozzle applicator. A venting aperture, controlled by a plug, is provided at the top of the gastight chamber, in order to relieve the gas pressure.</p> |
