Latest Patents

Holmes holds a patent for an "Impingement Oven and Method." This invention features a carrier-type conveyor that passes between hot air plenums located above and below the conveyor. The horizontally adjacent plenums have their fans positioned in an offset manner to overhang one another. Each plenum is equipped with a nozzle plate that directs heated air toward the conveyor, ensuring that the airflow is substantially perpendicular to the conveyor and any workpieces present. The design includes an oven module with four sets of plenums and four conveyors within the same enclosure. A series of such modules can be arranged to create a multizone oven, which is particularly effective for heating flat workpieces made of thermoplastic resin, intended for further processing into hollow objects like containers.
