Abstract:
A hot melt dispensing system includes a melter, a feed system, a dispenser and a filter. The feed system delivers hot melt pellets to the melter. The dispenser dispenses liquefied hot melt adhesive from the melter. The filter is connected to the feed system and prevents contaminants from passing through the feed system. In one embodiment, the filter comprises a screen filter positioned near a bottom of a pellet hopper. In another embodiment, the filter comprises a series of baffles positioned along the pellet hopper. In yet another embodiment, the filter comprises an electro-static filter coupled to a feed hose.
