HOT MELT ADHESIVE SYSTEM HAVING CENTRALIZED MANIFOLD AND ZONE HEATING CAPABILITY

摘要

A dispensing unit (20) for a hot adhesive system (10) has a manifold (26) centrally located within the dispensing unit (20) to permit commonality between heated hoses (46) of substantially the same length used to supply adhesive guns (51) at either side of the dispensing unit (20). The dispensing unit (20) also includes a manifold (26) that is thermally isolated from the adhesive tank (22). The manifold (26) has a heater (56) that is independent of the tank heater (34) for more precise temperature control of adhesive flowing through the manifold (26). A pump (58) coupled to the manifold (26) is located external to the tank (22) and is heated by the manifold heater (56).
