A consumable assembly for supplying filament to a 3D printer includes a spool-less filament coil, a payout tube, and a compressive band. The coil of filament is wound in a configuration having a generally cylindrical outer perimeter and an open interior; the coil has a payout hole extending from an inner layer of the coil to an outer layer of the coil and includes a filament strand configured to be withdrawn through the payout hole in response to a pull force, to thereby withdraw filament from the interior of the coil. The payout tube is disposed in the payout hole and provides a filament port. A compressive band is disposed over the outer layer and is configured to exert a compressive radial force on the coil so that the coil maintains its cylindrical shape without deformation, and the filament strand may be drawn through the filament outlet free of kinks, twists or tangles.

A threadlike adhesive sticking apparatus of the present invention is a threadlike adhesive sticking apparatus configured to press a threadlike adhesive wound in a roll shape together with a release liner against an object while feeding out the threadlike adhesive, and includes a pressing unit configured to press the threadlike adhesive debonded from the release liner against the object. A compression elastic modulus of the release liner is 1.5 MPa or less.

A power cable arrangement, in particular marine power cable, for offshore wind farms, including at least one cable drum device with a cable drum. The power cable arrangement includes at least one power cable wound on the cable drum with at least one cable end configured to pre-installing at a cable connection of a wind energy device. The power cable is wound on the cable drum such that a first section of the power cable is wound inversely to a further section of the power cable.

Packaged dispensers mountable to optical network terminals (ONT) are disclosed. In some examples, the dispensers include coreless wound coils and excess storage areas. Additionally, fiber optic cable distribution systems and methods thereof utilizing the disclosed coreless wound coils are further disclosed. In one example, a length of telecommunications cable is wound into a coreless coil that includes a plurality of winding separators at least partially embedded within the coil, wherein the length of telecommunications cable alternately passes on one of the first and second sides of one winding separator and on the other of the first and second sides of an adjacent winding separator. In one example, an initially cylindrically shaped coreless wound coil, with or without winding separators, can be placed into a non-round package in which the wound coil is deformed and compressed by the sidewalls of the package such that the coreless wound coil conforms to the interior perimeter of the package to have a non-cylindrical shape.

A locking ring is described that permits removal of filamentary material housed in a walled container through a payout tube defining a payout tube axis and through which a first end of the filamentary material extends. The ring includes an annular flange around a ring axis and a body having a tubular wall extending from an inner edge of the annular flange to a distal edge of the ring. The tubular wall is coaxial with the ring axis, and has a plurality of teeth circumferentially spaced around the tubular wall and extend from the tubular wall radially outwardly and toward the annular flange. Each tooth resiliently deflects radially inwardly in response to interference between the tooth and an inner wall of the payout tube. The curved edges form a thread permitting the ring to advance axially into and secure with the payout tube.

Systems and methods for winding wire are disclosed. A system includes a wire take-up unit and a wire tensioning unit. The take-up unit includes a rotating mandrel and a wire directing device, the wire directing device arranged to cause the wire to be wound in a figure-eight configuration on the rotating mandrel to form a coil having many layers of wire. The wire tensioning unit applies tension to said wire as it is wound, and applies a first amount of tension to a predetermined amount of wire constituting at least a first two layers of the coil, and a second amount of tension to the wire beyond the predetermined amount. In one embodiment, the wire tensioning unit includes digital self-relieving air regulator pneumatically coupled to and controlling a pressure in said pressurized chamber of a pre-lubricating cylinder that is coupled to the wire being wound.

A method of winding bulked continuous filament yarn is disclosed, which enables superior yarn package formation, including higher density packages with excellent shape and yarn takeoff characteristics. The method uses unique helix angles and winding profiles in a non-adjacent and adjacent yarn pattern, achieved by a unique winding control strategy that constantly monitors spindle speed, desired wind ratio, traverse cam speed, and surface speed.

A method of winding fibre to create a tubular winding by using at least three different motions to create interlocking segments. The interlocking segments may have at least one fibre parameter that is different, such as colour. The tubular winding may be bent into a curved shape so that a portion of each of the segments is visible.
