Provided are methods that can prevent either or both of kinking and collapsing of a steel sheet coiled in coil form regardless of the characteristics of the steel sheet. A method of determining a tension pattern of tension applied to a steel sheet to coil the steel sheet in coil form comprises calculating the tension pattern using an apparent elastic modulus in a radial direction of a coil.

An apparatus for winding coils onto a spherical body includes a frame, a feeder spool, a first hemispherical bobbin, a second hemispherical bobbin, a first spring-loaded pin, a second spring-loaded pin, and a motor arrangement. The feeder spool is rotationally mounted on the frame, has first and second wires wound thereon, and is configured to rotate about a first rotational axis. The first and second hemispherical bobbins are rotationally mounted on the frame and configured to rotate about a second rotational axis that is parallel to the first rotational axis. The bobbins are spaced apart from each other to define a wire-feeder gap through which the first and second wires may be fed. The motor arrangement is coupled to the first and second hemispherical bobbins and is configured to cause the first and second hemispherical bobbins to rotate in opposite directions about the second rotational axis.

An overlapping and progressive forming method for a high-performance multi-element NiAl-based alloy tubular part, including: winding continuously flexible substrates of Ni and Al, and alloying coating continuously or selectively along a width direction or a rolling direction to obtain coated flexible substrates; winding continuously the coated flexible substrates on an outer surface of a core roller according to a sequence of Ni above and Al below to form a Ni/Al laminated structure having a plurality of layers with an outermost layer being a Ni layer, and consolidating with ultrasonic with assistance of a pulse current to combine the continuously wound flexible substrates into a laminated tube blank; and placing the laminated tube blank into a mold, applying a pulse current to both ends of the laminated tube blank for hot fluid high-pressure forming, and synthesizing in-situ to prepare the tubular part with assistance of the pulse current.

Various storage containers are described for retaining drain cleaning cables. Storage systems utilizing the containers with a cable guide assembly are further described. Also described are methods of using the containers and systems.

A portable cutting line may include a frame and a lazy susan. The portable cutting line may also include a cutting line main table, the cutting line main table operatively connected to the lazy susan and one or more tubs, the tubs operatively connected to the cutting line main table. The lazy susan, the cutting line main table, and the one or more tubs may be positioned within the frame when in transport position.

A pouring reel for forming a hot rolled long product into an annular coil comprises a central mast lying on a vertical axis. A cylindrical tub surrounds and cooperates with the central mast to form an annular tub chamber. A coil plate defines a bottom of the tub chamber. The central mast, cylindrical tub and coil plate are rotatable in unison about the vertical axis. An entry nozzle has a delivery end arranged to direct the product downwardly into the tub chamber for accumulation on the coil plate as a series of superimposed rings forming the coil. The coil plate is movable downwardly along the vertical axis and relative to the central mast and the cylindrical tub to accommodate the increasing height of the coil being formed in the tub chamber.

A method for the handling of coreless auger, which is produced by an auger production machine from which the coreless auger emerges with a linear motion component and a rotational motion component, includes guiding the rotating auger for linear movement away from the production machine toward a temporary storage facility that has a cylindrical receptacle rotatable about its own axis and a coaxial rotatable feed guide having an axial inlet for formed auger and an outwardly directed outlet for directing formed auger toward an inner periphery of the cylindrical receptacle. The cylindrical receptacle is rotated and the feed guide is allowed to rotate about the axis of its inlet that is roughly coincident with the axis of auger entering the axial inlet of the feed guide. The cylindrical receptacle is rotated at a speed selected to counteract the rotation of the auger about its own axis.
