Abstract:
A hot melt adhesive material flow control system, comprising:an input manifold for receiving a supply of adhesive material from a supply source of adhesive material; a plurality of flow control valves for controlling the discharge of adhesive material therefrom such that adhesive material discharged from said plurality of flow control valves can be deposited upon a substrate in accordance with a predetermined pattern; at least one multiple-outlet pump for discharging adhesive material received from said input manifold toward said plurality of flow control valves; an output manifold within which the adhesive material discharged by said at least one multiple-outlet pump is heated so as to supply hot melt adhesive material to said plurality of flow control valves; and a first plate interposed between said input manifold and said output manifold and having first and second separate and independent fluid flow paths defined upon first and second opposite surfaces of said first plate, with a solid plate portion defined between said first and second opposite surfaces and said first and second separate and independent fluid flow paths defined upon said first and second opposite surfaces of said first plate, for respectively conducting adhesive material from said input manifold to said at least one multiple-outlet pump along said first fluid flow path, and from said at least one multiple-outlet pump toward said output manifold and said plurality of flow control valves along said second fluid flow path.
