Disclosed are systems and methods for feeding welding wire for welding-type applications. The wire-feeder system comprises a base platform, a spool hub, a drive roll assembly, and a wire guide assembly. The spool hub can be mounted to the base platform perpendicular to the base platform and configured to support a wire spool. The drive roll assembly can be mounted to the base platform, and having one or more sets of drive rollers configured to feed wire from the wire spool toward a welding torch. The wire guide assembly can be mounted to the base platform separately from both the wire spool and the drive roll assembly.

Various aspects of the present disclosure are directed to an unwinding mandrel for connecting to an unwinding apparatus for unwinding elongate materials and/or an unwinding system. In one example embodiment, an unwinding mandrel is disclosed including: a main part positioned in the center of a bundle of elongated materials; a connecting portion detachably connecting the unwinding mandrel to the unwinding apparatus; and at least one movable body pivotably connected by at least one joint to the main part, transversely to a main extension axis of the main part.

A cable dispensing system for unwinding a spool of cable not having a central core, the system comprising a tub having a base and a side wall with a side wall opening partially forming an inner space sized to fit the spool, the system further including an inner assembly having a base plate and a bearing assembly between the plate and the tub base, the bearing assembly supporting both the axial load and providing free rotation of the plate relative to the tub base about an inner space axis and unrestricted rotation of the associated spool about the system axis, the opening in the side wall allowing passage of the associated cable out of the inner space wherein pulling the cable out of the inner space rotates the associated spool about the inner space axis and unwinds the cable from the spool with low resistance and without kinking.

A modular spool storage device is configured to store a length of line, which is configurable between an assembled operational configuration and a disassembled transport configuration. In the assembled operational configuration, the device includes a ring with a U-shaped cross-section. The ring includes multiple ring sections, each ring section having two end faces, each end face being provided with at least one ring connector allowing the assembly of the ring by interconnection of the ring connectors of the multiple ling sections in circumferential direction from the disassembled transport configuration to the assembled operational configuration. The dimensions of a ring section fit into or correspond to that of an ISO shipping container so as to be transportable as or by an ISO shipping container.

A carousel for pipe products including cables and umbilicals includes a drum coupled to a carousel adapter, the carousel adapter coupled to a drive unit. The carousel adapter includes an upper base plate opposite a lower base plate, a fixed base leg coupled between the upper base plate and the lower base plate and extending radially outwardly therefrom. The carousel adapter also includes a plurality of foldable base legs coupled between the upper base plate and the lower base plate and extending radially outwardly from the upper and lower base plates. Each of the foldable base legs is disposed about a periphery of the upper and lower base plates and is rotatable about an independent axis perpendicular to the upper base plate and the lower base plate.
