Claim Text:
1. A system for regulated and controlled application of adhesive to substrates comprising: a) a container for containing a supply of adhesive in a plurality of pellets; b) a hot-melt tank for containing a supply of adhesive; c) a vacuum feed system for transferring the pellets from the container to the hot melt tank; d) a level sensor in said hot-melt tank to automatically control the flow of adhesive through the vacuum pump; e) at least one applicator nozzle; f) a piping system for guiding the flow of adhesive from said hot-melt tank to said nozzle; g) an application equipment located between said hot-melt tank and said nozzle; h) a mass flow meter located between said sensor and said nozzle; i) a control unit with an associated data processing program, said control unit being operable to control pressure in said piping system in response to the signals received from said mass flow meter, said control unit operable to program a minimum and a maximum acceptable amount of the adhesive over a specific area, and to regulate consistent and even application of adhesive to a substrate; and j) a positioning detection system located after said nozzle, said positioning detection system operable to identify the position and the minimum and the maximum acceptable amount of the adhesive on each substrate by sending a signal at specific time frames, said control unit being operable to control removal of defective substrate in response to the signals received from said positioning detection system.
