A preform coating device is provided with: a conveyance part that conveys a preform; a dispenser that discharges a coating liquid toward the preform; a drier that is disposed along the conveyance route of the conveyance part so as to be separated from the dispenser, and that dries the coating liquid applied to the preform by irradiating, with infrared rays, the coating liquid applied to the preform; and a first air sending mechanism that sends air, toward the preform, for inhibiting the temperature of the preform from rising at the position where the preform is irradiated with infrared rays by the drier.

An apparatus for preparing a liquid material containing microbubbles includes a dispensing nozzle and a first positive displacement gas pump. The dispensing nozzles includes a material mixing channel, a rotary gas diffuser positioned in the material mixing channel, and a rotary mixer positioned in the material mixing channel downstream of the rotary gas diffuser. The rotary gas diffuser and the rotary mixer rotate about a common axis of rotation. The first positive displacement pump has a first gas outlet opening to the material mixing channel, which is directed at an outer circumference of the rotary gas diffuser.

An integral melter and pump assembly or system, and a method of making the same, is disclosed wherein the pump assembly comprises a melter housing having a melter container defined within the melter housing. A pump mounting plate is integrally mounted within a side wall portion of the melter container and an output dispensing supply pump is mounted directly upon an external surface portion of the pump mounting plate in a surface-to-surface manner such that heat generated internally within the melter container is effectively transferred by conduction from the melter container and through the pump mounting plate such that the temperature level of the output pump is elevated to, and maintained at, a predeterminedly desired level even when the pump, is not disposed in its output dispensing mode. In addition, since the output dispensing or material supply pump is disposed externally of the melter container and the melter housing, the output dispensing or material supply pump is easily and readily accessible in case maintenance becomes necessary. Optionally, an oil jacket or chamber can surround the melter container so as to more evenly or consistently provide heating of the melter container.

A fluid application device having a modular nozzle assembly is provided. The fluid application device includes an applicator head and a modular nozzle assembly fluidly coupled thereto. The modular nozzle assembly includes at least one guide slot configured to receive a strand of material, at least one orifice configured to discharge a first fluid onto a respective strand of material, and at least one securing opening extending through the modular nozzle assembly. Each securing opening is configured to receive a releasable securing element. The modular nozzle assembly may be a contact nozzle assembly or a non-contact nozzle assembly, and include fluid or air assist for altering a flow of the first fluid. The modular nozzle assembly may be selectively removed from and secured to the fluid application device so that the modular nozzle assembly may be selectively switched between the contact nozzle assembly and the non-contact nozzle assembly.

A fluid application device having a contact nozzle assembly with a fluidic oscillator is provided. The fluid application device includes an applicator head and a nozzle assembly. The nozzle assembly includes a first conduit configured to receive a first fluid from the applicator head, a second conduit configured to receive a second fluid from the applicator head and an application conduit including a receptacle and first and second branches. The receptacle is fluidically connected with the first conduit and configured to receive the first fluid. The first and second branches are fluidically connected to the second conduit and receptacle and are configured to receive the second fluid. The nozzle assembly further includes an orifice fluidically connected to the application conduit and configured to discharge the first fluid for application onto a strand of material, and a guide slot extending from the orifice and configured to receive the strand of material.

An apparatus for melting and dispensing thermoplastic material is provided that includes an un-heated hopper having an inlet for receiving particles of a thermoplastic material and an outlet for discharging the particles and a heated manifold including at least one cavity formed therein and having an inlet and an outlet the inlet communicating with the outlet of the hopper for receipt of the particles from the hopper. The hopper is disposed external of the heated manifold. The heated manifold is effective for melting the particles into molten thermoplastic material therein. The apparatus further includes a pump having an inlet in fluid communication with the cavity. An outlet of the pump is in fluid communication with an inlet of a dispenser and an outlet of the dispenser is effective for dispensing the molten thermoplastic material therethrough.

A seal agent coating device is disclosed, comprising: a storage cavity, a nozzle, a connecting duct and a power driven component, wherein: the nozzle comprises a nozzle cavity and a mouth, the mouth being located at the lower part of the nozzle cavity and matching with the shape of the seal agent coating area of the substrate; the connecting duct interconnects the storage cavity and the nozzle cavity; the power driven component can squeeze the seal agent in the storage cavity into the nozzle cavity via the connecting duct, thereby squeezing it out via the mouth.

Methods and systems for forming a layer from a fluid mixture on a web are provided. The system includes a fluid delivery apparatus for delivering the fluid mixture onto the web. The fluid delivery apparatus includes a cascade device and a chemical dispenser device. The system also includes a fluid stirring apparatus comprising at least one fan positioned over the web and configured to generate a flow pattern that stirs the fluid mixture on the web while the layer is being formed, without the at least one fan contacting the fluid mixture. The system further includes a fluid removal apparatus having a rinsing device and a suction device. The rinsing device is configured to dispense a rinsing fluid onto the web. The suction device is configured to remove by suction the rinsing fluid and a remaining portion of the fluid mixture remaining on the web after formation of the layer.

A method is used to identify and compensate for errors created by changes in the relative positions of a deposition unit and a vision system of a dispenser. The method includes calibrating the vision system, dispensing a pattern of features over a working area, moving the vision system over a deposition location to locate a deposition, obtaining an image of the deposition, tagging data associated with the image, calculating a relative distance between the deposition unit and the vision system, storing correction data with spatial location in a file for later use, and using the stored data to make small corrections prior to dispensing additional material.
