Apparatus for manufacturing a respirator cartridge seal |
摘要 |
A process and apparatus for forming a seal between a filter cartridge wall and a pleated filter disposed within the cartridge having a support for rotating the cartridge. A nozzle is connected to a source of sealant for injecting sealant into an area between the wall of the cartridge and the filter media. A valve connected to the nozzle valves sealant to the nozzle and has a draw back feature after a desired amount of sealant is injected. The method for sealing the filter media to the wall of the cartridge includes rotating the filter cartridge while disposing a nozzle into the interior of the cartridge and injecting a sealant through the nozzle controlled by a valve. The valve draws flow backwardly from the nozzle at the termination of the injection of sealant.
