A wind turbine tower cleaning or coating apparatus is provided. The apparatus includes a frame which circumferentially extends at least partially around a wind turbine tower. A separator structure can be attached to the frame and extends between the frame and the wind turbine tower to position the frame at a predetermined distance away from the wind turbine tower. A slider can be attached to the slidable end of the separator structure and can slide on the surface of the wind turbine tower as the frame is raised and lowered on the wind turbine tower. A plurality of sprayers can be positioned circumferentially along the frame and configured to selectively spray fluid onto the wind turbine tower. In one embodiment, a hoist device is attached to the frame to hoist the wind turbine cleaning or coating device vertically up and down the wind turbine tower.

摘要:
Apparatus for coating a pipe (6). The apparatus includes a first frame (2) to be mounted on a pipe and a second frame (4) rotatably mounted on the first frame (2). An induction heating coil comprised of electrical conductors (14) is mounted on the apparatus. A coating applicator (42) is mounted on the second frame (4) and is arranged to apply coating onto a surface of the pipe (6) on which the apparatus is mounted. The first frame (2), second frame (4) and coating applicator (42) are arranged such that when the apparatus is mounted on the pipe, the applicator (42) is disposed to one side of the induction heating coil and able to apply coating to a surface of the pipe alongside the surface of the pipe (S) underlying the induction heating coil. The first frame (2) may be operable between an open state in which the frame may be placed over and removed from a pipe and a closed state in which the frame may capture a pipe thereby to mount the apparatus on the pipe.

Method and apparatus for coating a pipe (2) or a pipe section with a layer of at least one polymer. The method comprises providing a pipe (2) or a pipe section having an outer surface defining the periphery of the pipe or pipe section; applying on the outer surface of the pipe or pipe section a layer of at least one polymer material in melt stage using a nozzle (3), which is mounted on a carriage capable of travelling along the periphery of the pipe (2) or pipe section; and moving the carriage along at least a part of the periphery during the application of the polymer material to form a layer on the surface of the pipe (2) or pipe section. The present invention is particularly useful for coating field joints in pipelines.

Es wird ein Verfahren zum Beschichten einer geschweißten oder geklebten Naht eines wenigstens einseitig bis auf den Bereich der Naht mit einer aufgeklebten Folie versehenen Behälters, der durch eine Fördereinrichtung einer Beschichtungsstation zum Auftragen einer Beschichtungsmasse auf die Schweißnaht oder Klebenaht zugeführt wird, beschrieben, wobei die Außenseite oder die Innenseite der Schweißnaht oder Klebenaht über eine Düse überlappend beschichtet wird, indem ein reaktiver Schmelzklebstoff als Beschichtungsmasse verwendet wird.
摘要:
A coating device for coating a peripheral surface of a sleeve body (13) with a coating formulation (24) is presented. The coating device comprises a vertical support column (1) for supporting a sleeve body (13) in a vertical position coaxial with a coating axis (10), a carriage (5,29) slideable along the vertical support column (1), and an annular coating stage (11) attached to the carriage (5,29) and moveable therewith for containing the coating formulation (24) and for coating a layer of the coating formulation (24) onto the peripheral surface of the sleeve body (13) during a sliding movement of the carriage (5,29) along the vertical support column (1). The coating device is characterised by having an irradiation stage (12,52), moveable with the annular coating stage (11), for providing radiation to at least partially cure the layer of coating formulation (24) onto the peripheral surface so as to prevent flow off of the coating formulation (24).

An apparatus and method is provided to allow higher volume production of medical devices and to minimize coating defects resulting from manual handling of medical devices by supporting multiple medical devices at the same time and performing one or more process steps automatically.
摘要:
There is described an apparatus (1) for coating a cylinder (C), in particular a wiping cylinder of an intaglio printing press, with a plastic composition comprising inter alia heating means (6) for applying radiant heat to the cylinder throughout its length as the cylinder is rotated, the heating means including a plurality of discrete heating elements (60) distributed along the length of the cylinder and around at least part of the peripheral surface of the cylinder, the heating elements being arranged at least in separate columns (60a to 6Oh) disposed parallel to one another along the length of the cylinder. The apparatus further comprises a temperature sensing system (9) for measuring the surface temperature of the cylinder along the length of the cylinder and a processing unit coupled to the temperature sensing system (9) for controlling operation of the heating elements (60) as a function of the measured surface temperature and a desired temperature setting (t c ). The temperature sensing system (9) is adapted to output a temperature measurement profile (T m ) representative of the surface temperature of the cylinder measured along the length of the cylinder, the temperature measurement profile being subdivided into a plurality of zones (Z1 to Z8) each associated to one corresponding column of heating elements (60a to 6Oh). Operation of each column of heating elements (60a to 6Oh) is controlled by the processing unit on the basis of the surface temperature measured within at least one of the zones (Z1 to Z8).
摘要:
A process and system for applying an adhesive (18) to a core (16) during the production of rolled paper (11) products is disclosed. The system of the present invention is generally directed to the use of pumping devices that meter out constant volumetric amounts of an adhesive onto a core through a plurality of adhesive applicators simultaneously. The systems includes, for instance, a positive displacement pump system in which a fluid at substantially constant pressure is fed to a pumping device for dispensing the adhesive to a plurality of adhesive applicators in constant volumetric amounts.
