INFORMATION COMMUNICATION SYSTEMS BETWEEN COMPONENTS OF A HOT MELT ADHESIVE MATERIAL DISPENSING SYSTEM

摘要

A hot melt adhesive material dispensing system includes a communication system for transmitting information or data between the adhesive supply unit (ASU) and one or more applicator heads, wherein the number of hard wires actually interconnecting the adhesive supply unit (ASU) and the one or more hot melt adhesive material dispensing applicator heads can be reduced by the employment of signal couplers. In addition, the number of applicator heads that can be utilized in conjunction with a particular adhesive supply unit (ASU) can be increased by incorporating the temperature controller, normally disposed upon the adhesive supply unit (ASU), upon the applicator head.
