The purpose of the present invention is to provide a viscous material application apparatus capable of reliably applying an appropriate amount of a viscous material to a shaft-shaped member. A seal application apparatus (1) is provided with a flexible tubular nozzle (2), which is capable of discharging a sealing agent from an opening (6) formed on the tip thereof, and an actuator (3) for moving the nozzle (2). After or during discharge of the sealing agent by the nozzle (2), the tip of the nozzle (2) moves in the circumferential direction along the outer circumferential surface of a fastener (20), and as the nozzle (2) is stopping the discharge of the sealing agent, the tip of the nozzle (2) moves in a direction away from the outer circumferential surface of the fastener (20).

A pipe washing and drying system includes a ring structure defining a radially inner surface and a radially outer surface, the ring structure having a first portion and a second portion hingedly coupled to the first portion. The ring structure further comprises nozzles and rollers defined in the radially inner surface and extending radially inward. The pipe washing and drying system may further include a tent structure comprising a frame and a protective covering supported thereby. The tent frame is coupled between two of the ring structures such that the protective covering covers a section of the pipe between the two ring structures.

A method of coating threads using a printhead having rows of nozzles extending along a length of the printhead. The method includes the steps of: feeding the thread along a length of the printhead; and ejecting ink from the rows of nozzles towards the thread. Thread-coating modules and thread-coating systems make use of the method described.

Provided is an apparatus for coating a girth weld and a cutback region surrounding said girth weld, said apparatus having lateral travel at least equal to the length of the cutback region and circumferential rotational travel around the pipe. The apparatus can provide a multiple component coating accurately and safely, without the need for solvent flushing of the apparatus.

An apparatus for cleaning the trunk of a tree is disclosed. The apparatus comprises a pressure washer in fluid communication with a water source and a conduit in fluid communication with the pressure washer to receive a flow of pressurized water expelled therefrom. The conduit is arranged in at least a semi-circle to at least partially extend around the diameter of a tree trunk. A plurality of spray nozzles is disposed along the conduit to expel pressurized water from the conduit to clean the tree trunk. A barrier is connected to the conduit to impede the pressurized water from travelling in an undesired direction.

A pipe conditioning tool comprising a drive unit to move the tool along a pipe and a work head rotatable about an axis of the pipe to condition a surface of the pipe, the drive unit includes a frame extending to opposite sides of the pipe, the frame having legs extending radially beyond the work head to provide support for the tool upon removal from said pipe.

A device (1) applies adhesive to cores which are used to produce a log includes a moving means (3) configured to cause at least one core (5) to advance along a feed direction (A) and a dispensing means (7) configured for dispensing an amount of adhesive (9) on the core (5). The dispensing means (7) are moveable along an application direction (B) substantially orthogonal to the feed direction (A) and are configured to selectively dispense an amount of adhesive (9) along portions (11) of the core (5) during movement along the application direction (B).

The invention relates to a tool (1) for applying liquid agent such as, for example, an insulating foam, an adhesive, or paint to the mantle surface of a circular-cylindrical object (10), comprising a tool head (2) having an axially through hole (3) with a substantially circular cross-section. The tool head (2) comprises an inner flange (8), an outer flange (16), a distribution chamber (12) running around the inner flange (8) and that comprises at least one outlet (13; 23; 33) distributed around the through hole (3). An asymmetrical restriction is arranged at the outlet (13) so that the outlet is restricted where the pressure is as highest (14). The invention also relates to a method for applying an agent around a circular-cylindrical object (10) with the tool (1).

Coating apparatus for coating cylindrical hollow bodies, having a machine frame and a workpiece rotary table which is equipped with a plurality of holding mandrels mounted rotatably on the workpiece rotary table, and having a coating station arranged on the machine frame, wherein the coating station includes a rotatably mounted coating roller, wherein axes of rotation of the holding mandrels and an axis of rotation of the coating roller are aligned parallel to one another, wherein the coating roller has a coating region and a free-wheeling region on a circumferential surface, the coating region being designed as a circular cylinder segment with a constant circular radius coaxial with the axis of rotation of the coating roller, and the free-wheeling region being formed from surface sections which each have a distance from the axis of rotation of the coating roller which is smaller than the circular radius.

An object is to suppress a variation in amount of a sealant that is applied on an object to be sealed. There is provided a sealant discharge nozzle configured such that a sealant from a cartridge is discharged from a discharge hole of the sealant discharge nozzle. The sealant discharge nozzle has a leading end portion comprising a pair of side wall portions; and a connecting wall portion configured to connect the pair of side wall portions with each other and provided in cooperation with the pair of side wall portions to form a first recess that is open on one side in a first direction perpendicular to an axial direction of the sealant discharge nozzle, and on a leading end side. The discharge hole has an opening formed on a first recess side of the connecting wall portion.
