Abstract

See full text

System and process that continuously circulates hotmelt adhesive at a circulating pressure rate to apply hotmelt adhesive to a moving substrate on a substrate delivery conveyor. The system includes an adhesive delivery line connected to an elongated manifold, the manifold including: (i) a main internal fluid pathway in fluid communication with the adhesive delivery line and an adhesive return line, and (ii) an elongated heater providing a substantially constant internal temperature to the elongated manifold. An adhesive pump transporting hotmelt adhesive from the adhesive reservoir to the adhesive delivery line under pressure, the adhesive reservoir including a filter that filters hotmelt adhesive. A plurality of hotmelt spray heads in fluid communication with the main internal fluid pathway to dispense hotmelt adhesive onto the moving substrate. The adhesive return line in fluid communication with the adhesive pump and/or the adhesive reservoir to transport hotmelt adhesive from the elongated manifold.
