Dispensing process particularly for a sealing/adhesive product

An apparatus for continuously deaerating and dispensing anaerobic adhesive product comprising:

• (a) two deaerators, each comprising a chamber having an upper portion and a lower portion, with an inlet at the upper portion, an outlet at the lower portion, a strainer at the upper portion below the inlet and two ports below the strainer, each dearator providing dearated adhesive product;
• (b) at least one feeding system which brings adhesive product into the chambers through the inlets;
• (c) at least one first cutoff valve connected at one end to the feeding system and at the other end to the inlets of the chambers to regulate the flow of the product into the chambers and through the strainers;
• (d) two vacuum and pressurizing systems, each system comprising a vacuum pump connected to one of the ports of one of the chambers and a pressurizing device connected to the other port of that chamber;
• (e) a dispensing system which distributes the deaerated adhesive product onto a work piece;
• (f) two transporting systems which carry deaerated product from the lower portion of each of the chambers through the outlets to the dispensing system;
• (g) at least one second cutoff valve which is connected at one end to the transporting systems and at the other end to the dispensing system, such that the flow of deaerated adhesive product from any one deaerator can be stopped at the same time that the flow from any other deaerator can be initiated;
• the cutoff valves are synchronized and the deaerators work in parallel, operating in alternating cycles such that while one deaerator is performing the deaeration of the adhesive product, the other deaerator is sending deaerated product to the dispensing system, allowing for a continuous deaeration and feeding of deaerated product to the dispensing system.
