  • Publication number: 20230321672
    Abstract: An applicator system for applying a material to a substrate is disclosed, the applicator system having a nozzle assembly that includes a nozzle having a nozzle head. The nozzle assembly also includes a baffle plate including a cutout that extends through the baffle plate, where the baffle plate is received by the nozzle head such that the nozzle head and the baffle plate define a cavity. The nozzle assembly further includes a cover plate attached to the nozzle head such that the cover plate secures the baffle plate within the nozzle head, where an outlet passage is defined between the baffle plate and the cover plate, the outlet passage being fluidly connected to the cavity through the cutout of the baffle plate.

  • Publication number: 20230286012
    Abstract: A metering distribution assembly and a coating system. The metering distribution assembly includes a volumetric cavity pump that comprises a flow passage plate having flow passages, a nozzle plate with a flow passage, a gear fixing plate attached between the flow passage plate and the nozzle plate, and a gear set located in an aperture of the fixing plate. The gear set has a fluid inlet and a fluid outlet on a side of the gear set opposite to the fluid inlet. The fluid inlet is in fluid communication with the flow passages of the flow passage plate, and the fluid outlet is in fluid communication with the flow passage of the nozzle plate. A part of the flow passages of the flow passage plate, which is in direct fluid communication with the fluid inlet, extends in a direction parallel to a rotation axis of the gear set.
