Systems and methods of threading a metal substrate on a rolling mill include receiving a coil of the metal substrate. The method also includes uncoiling the metal substrate from the coil while the coil and guiding the metal substrate to a work stand of the rolling mill with a threading system.

This gate device is provided with a guide unit having a guide section that is disposed at the downstream side of pinch rollers at a path line along which a metal sheet is conveyed, opens/closes a coil-up line that is curved from the path line, and guides the upwards-facing surface side of the metal sheet led in to the coil-up line. A configuration is adopted such that the guide unit has a main body frame and a liner that is attached to the main body frame, forms at least a portion of the second guide surface that guides the metal sheet, has a lower coefficient of friction than the main body frame, and has a lower hardness than that of the metal sheet.

A coiler device (1), provided with a chute roller (50), has: pinch rollers (10a, 10b) that lead a metal sheet carried in along a path line (L1) to a coil-up line (L2) that is curved from the path line (L1); a mandrel (20) that coils the metal sheet and is disposed ahead of the coil-up line (L2); and a chute roller (50) that exposes at least the leading end of the metal sheet to the coil-up line (L2) when being wound to the mandrel (20), and suppresses curving of the metal sheet toward a surface of the metal sheet facing the chute roller (50).

A system for controlling multiple wire feed motors for use in a welding-type system including a push motor controlled to operate at a target wire feed speed and a pull motor disposed in a welding torch controlled to apply a target torque to the fed welding wire. Such a system eliminates shaving and bird nesting of welding wire.

A wire handling device for a manufacturing device includes an elongate first wire guiding device having a first guiding section for a wire to be guided along the first guide section, and an elongate second wire guiding device having a second guiding section for a wire to be guided along the second guide section. The wire handling device includes a support device, and the first wire guiding device and the second wire guiding device are placed on the support device. The support device is rotatably mounted about the rotational axis, and the first wire guiding device and the second wire guiding device are mounted so that they can be moved with respect to each other.

This coiler device provided with a chute guide has: pinch rollers that lead a metal sheet carried in along a path line to a coil-up line that is curved from the path line; a mandrel that is disposed ahead of the coil-up line and coils up the metal sheet; and a chute guide that guides the upward-facing surface side of the metal sheet at the coil-up line and introduces the metal sheet to the coil-up opening of the mandrel. A configuration is adopted such that the chute guide has: a main body frame; and a liner that is attached to the main body frame, forms at least a portion of the guide surface that guides the metal sheet, has a lower coefficient of friction than the main body frame, and has a lower hardness than the metal sheet.

Aspects of the present invention relate to a coil sampling stand apparatus which generally has a frame, at least two rollers operatively coupled to the frame, a roller drive operatively coupled to at least one of the at least two rollers, and a peeler assembly comprising a peeler (e.g., peeler, knife, member with an edge, or the like) that is configured to engage and disengage a coil between the at least two rollers. The steel coil may be positioned onto the at least two rollers on the frame of the coil sampling apparatus. The peeler is engaged with the coil and the coil is rotated in order to allow the peeler to peel a tail edge of a layer of the coil off the coil and pass the tail edge and layer of the coil peeled off of the coil under at least one of the rollers.

A production system for processing a wire material wound to form a wire reel, in particular reinforcing steel. The production system comprises a receiving device for receiving the wire reel; an unreeling device for removing the wire material on the wire reel; and a processing device for processing the removed wire material. The unreeling device comprises a conveyor surrounding a first deflection roller and a second deflection roller, wherein permanent magnets are arranged on the conveyor and an increased frictional connection can be established between a surface of the wire material and an outer surface of the conveying means by means of the permanent magnets.

A device for transporting elongated metal material comprises two chain drive units with a continuous chain, which are arranged such that the elongated material is passed through between the chains with frictional contact so that the elongated material is moved; two controllable pressure units configured to apply pressure forces to the chains towards each other; at least one controllable adjusting unit which is mechanically connected to at least one of the chain drive units and which is configured to move same in a longitudinal direction of the elongated material during operation. A plant can have such a device, and a process is used for controlling such a device.
