PVA, a global expert in dispensing, coating and custom automation, is pleased to announce that it has been granted a new patent. Patent No. US 10,328,448 B2 pertains to the method of cleaning adhesive residue off of a dispensing nozzle using an integrated blow off mechanism. The mechanism uses compressed air to virtually wipe the nozzle clean vs. having to immerse in solvent or use a physical wiper or other mechanism that must contact and clean the nozzle.
“This recognition shows that PVA is not only focused on developing world class liquid dispensing and spraying devices but also improving the ancillary tools that improve application performance and maintenance of these devices,” states Jon Urquhart, Director of Application Engineering at PVA.
Urquhart added: “This cleaning mechanism provides a method to remove adhesive residue that can build up on a dispensing nozzle with a virtual wiping action from pressurized air directed at the nozzle. This development has shown to greatly improve dispensing accuracy by enabling the user to have a clean dispensing nozzle at the beginning of every dispense cycle plus eliminating the step of using a physical wiper or solvent to clean the nozzle which can be messy or require additional consumables.”
