A tape applicator assembly for securing tape to a surface includes a body and may include a centering and locking assembly configured to automatically center and lock a tape assembly within the body for dispensing. The tape applicator assembly may further be configured for securing tape to at least one cable and a surface, wherein the body includes a tape-receiving cavity defined for receiving a tape assembly having tape with a tape center longitudinal axis. A tape applying assembly may be defined within the body that is configured to adhere the tape to both the at least one cable and the surface. A cable alignment assembly may also be defined within the body that is configured to receive at least one cable positioned against the surface and substantially align the at least one cable with the tape center longitudinal axis.

A pipe joint coating for welded ends of pipes forming a pipeline. A last and third layer of a 3LPP coating system covering at least a circumferential weld area of the pipe joint is a heated sheet applied around the pipe with a machine including a mounting frame and a transport carriage rotatably movable on the mounting frame to move circumferentially about the pipe joint, and a roller applying an adjusted pressure to the sheet against the pipe and adapting to eccentricity or ovality of the pipe. The sheet is pressed below the pipe away from its overlapping ends, a first part of the sheet is then applied when the roller is rolled in a first direction, and a second part of the sheet is applied by the roller rolled back in the reverse direction around the pipe. The sheet is dimensioned to obtain an overlapped area between its extremities.

A method of applying protective sheeting of polymer material to a pipeline extending along a longitudinal axis and having a cutback bounded at opposite axial ends by two end portions of respective protective coatings of polymer material, the method including directly heating the free faces of the end portions; extruding and simultaneously winding about the pipeline a protective sheeting wide enough to cover the cutback and the end portions; and compressing the protective sheeting against the pipeline, the end portions included.

A former including: a guide pipe guiding an optical fiber bundle; a tape forming section forming a press-wrapping tape from a strip shape into a helical shape, while guiding the press-wrapping tape along a feed direction, the tape forming section including a curved section gradually curving the strip shaped press-wrapping tape while guiding the press-wrapping tape along the feed direction, and a helical section that is a helical tube shaped location further to a downstream side than a position where two edges of the curved section intersect with each other, the helical section causing two end portions of the press-wrapping tape that has been curved with the curved section to overlap and forming the press-wrapping tape into a helical shape, while guiding the press-wrapping tape along the feed direction, and gradually narrowing an external diameter of the helical shaped press-wrapping tape.

A pipe lining apparatus having a settable, resin-impregnated reinforcement filament that is helically wound onto the inner surface of a pipe or pipe lining by an inverted filament winding apparatus, the apparatus having multiple spools and applicator arms to retain and apply the filament. The applicator arms may be aligned circumferentially or axially.

A screen film applicator includes a seat, a positioning member, and a first mechanism, the latter two of which are disposed on the seat. The seat has a track and a positioning portion arranged beside the track. The positioning member is movable with respect to the positioning portion for clamping a communication device. The first mechanism includes a top fixing member disposed on the seat, a moving carriage movable along the track, a bottom fixing member synchronously movable with the moving carriage, and a roller movable with the moving carriage. The top and the bottom fixing members are configured to respectively fix a top releasing film and a bottom releasing film respectively adhered on two opposite sides of a soft screen film. When the moving carriage is moved away from the top fixing member, the roller can gradually press the soft screen film onto the communication device.

The tape applicator assembly may further be configured for securing tape to at least one cable and a surface, wherein the body includes a tape-receiving cavity defined for receiving a tape assembly having tape with a tape center longitudinal axis. A tape applying assembly may be defined within the body that is configured to adhere the tape to both the at least one cable and the surface. A cable alignment assembly may also be defined within the body that is configured to receive at least one cable positioned against the surface and substantially align the at least one cable with the tape center longitudinal axis.

A wrap tape cassette for a subsea pipeline repair or coating machine includes a drum for carrying a wrap tape wound on the drum. A housing defines an exit opening for the wrap tape to be dispensed from the drum onto a pipeline during a repair or coating operation. The drum may be mounted to the housing for rotational and longitudinal movement relative to the housing to dispense the wrap tape through the exit opening on being unwound from the drum. A leading end of the wrap tape may be attached to an anchor element that is arranged as a closure for the exit opening and, when moved from the exit opening, for attachment to a pipeline being repaired or coated.

There is provided a method for applying thermosetting tape on contoured resilient surfaces off an object which comprises biasing selected section(s) of the resilient member to minimize tape and object distortion. There is also provided a tape laying apparatus configured to enable the optimization of automatic tape application on resilient contoured surfaces and minimize tape and object distortion.

A production line for producing components to a high standard of cleanliness and sealed and protected in that state includes a loading device, a cleaning device, a detecting device, a pasting device, a heat-sealing device, a packing device, and transfer devices of the production line. The production line automatically processes the components for obtaining components with the high cleanliness. By the processes of protective film pasting, heat-sealing, and packing, the components may be further protected from subsequent pollution. A method for producing components with a high cleanliness applied to the production line is also disclosed.
