Abstract:
A method for applying a predetermined pattern of material onto an elongate tubular substrate includes securing a first portion of an elongate tube having a non-circular outer perimeter to an engagement member configured to be rotated by a first motor, such that the elongate tube can be rotated in unison with the engagement member, operating the first motor to rotate the elongate tube, operating a second motor of to change the relative displacement between the elongate tube and a dispensing conduit along a longitudinal axis of the elongate tube, and expelling a conductive adhesive from a fluid dispenser through the dispensing conduit to form a predetermined pattern of the conductive adhesive on a surface of the elongate tube, the predetermined pattern of the conductive adhesive covering at least 180 degrees of the surface along the non-circular outer perimeter over a width of at least two millimeters along the longitudinal axis.
Abstract:
A method of treating a tubular surface which defines an axis extending from a first surface end to a second surface end includes partially surrounding the tubular surface, at a first position, with a first set of treating units, with the treating units arranged in a first arcuate array. Furthermore, each treating unit is configured to include a plurality of first applicator heads. Additionally, an embodiment of the method includes determining a position of each of the plurality of first applicator heads relative to the tubular surface and moving the first set of treating units from the first position towards a second position. In one non-limiting example, the method further includes independently controlling each of the plurality of first applicator heads to selectively apply a first treatment as the first set of treating units moves from the first position towards the second position.
Abstract:
A coating apparatus for coating a perimeter surface of a pipeline. A frame selectively mounts a sprayer on the pipeline. The sprayer can spray fluid along a flow path in a spraying mode and preparation mode. In the preparation mode, a fluid diverter moves into the flow path to divert the fluid delivered from the sprayer away from the pipeline. In the spraying mode, the fluid diverter moves out of the flow path to permit the sprayer to coat the perimeter surface of the pipeline with a curable liquid. A vacuum system can draw a vacuum through the diverter to remove the fluid the sprayer sprays in the preparation mode. The flow path can be located in a spray shroud. The diverter can fluidly couple the vacuum system to the shroud interior in the spraying mode to remove overspray.
Abstract:
A method of coating an exterior surface of the elongate object with the coating material includes holding the elongate object lengthwise in the elongate chamber, mixing the pressurized air and the coating material to form a mist, and coating the exterior surface while directing the mist around the exterior surface and toward the outlet of the elongate chamber.
Abstract:
A method and devices for dispensing adhesive onto an elastic strand are configured to apply first, second, and third volumes of adhesive onto first, second, and third portions of the elastic strand, respectively. When the elastic strand is adhesively secured to a substrate to form a personal disposable hygiene product, the first and third portions of the elastic strand define opposing ends of the elastic strand, which are adhered with a larger amount of adhesive or a stronger adhesive material capable of limiting movement of the strand at the opposing ends. The method and devices advantageously use a module and nozzle which maintain separation between first and second adhesive streams received from different adhesive supplies at least until flow within the nozzle. This arrangement enables use of different adhesives to form the first, second, and third volumes, as well as “wet-on-wet” contact dispensing using multiple nozzle outlets.

Abstract:
An apparatus is provided for coloring threaded material. A payout support member of the apparatus is configured to support a payout spool. A drive member is configured to rotate a takeup spool. A coloring assembly comprises a colorant applicator holding portion that is configured to receive a colorant applicator. The coloring assembly also includes a passage configured to receive a thread and to dispose the thread against the colorant applicator as the thread is wound onto the takeup spool. The coloring assembly is positioned to direct the thread drawn through the passage toward a portion of the takeup spool.
Abstract:
Methods and systems comprising a first and a second powder coating apparatus, with each apparatus comprising a tubular barrel having an axial bore extending longitudinally therethrough, are usable for coating an interior surface of a tubular member. Each coating apparatus comprises a conical member connected with the tubular barrel and at least one gas conduit connected to the tubular barrel for communicating gas into the tubular barrel. The at least one gas conduit contains a gas flow control valve connected thereto for controlling the volumetric flow rate of gas through the at least one gas conduit. Each coating apparatus further comprises at least one container for holding a coating material, an inlet conduit for communicating the coating material into the axial bore of the tubular barrel, and a plurality of gas nozzles connected to the tubular barrel for inducing spiraling gas flow through the axial bore of the tubular barrel.
Abstract:
A plant for the surface decoration of elongate items includes an inlet section and an outlet section for one or more items having an external peripheral surface to be decorated, a support system for the elongated objects on a predetermined lying plane, a system for continuously forwarding the items from the inlet section to the outlet section along a longitudinal feeding direction, with the items substantially parallel to the same longitudinal direction, and a decorating system for the external surface of the items. The decorating system includes a plurality of jet devices arranged along the longitudinal direction, at least one of which is oriented to direct a jet of a pigmented substance on a portion of the external surface of the items at least partially different from another surface portion designed to be decorated by another device. A method for decorating elongate objects is also described.
Abstract:
Methods and apparatus are provided for a system for applying a fluid chemical treatment to a vertical column. In one embodiment the system includes a frame configured to generally surround the column, with a substantial gap between an inner surface of the frame and an outer surface of the column. The system may further include a centering guide on the inner surface of the frame, and an array of fluid spray nozzles connected to a pressurized fluid chemical source, and arranged to apply a uniform spray coating to the column. A mobility system vertically translates the frame along the column in a level orientation while fluid chemical is being applied.
