A multifunction work apparatus includes a drawing and yielding assembly and at least one of either a wire guide assembly, a straightening assembly, or a finishing assembly. The drawing and yielding assembly includes a contrast roll, rotatable idly around its axis of rotation, and at least two motorized rolls positioned on the periphery of said contrast roll.

Provided is a control device for a plate feeding device with which the amount of a plate transported to a processing device by the plate feeding device can be measured with high accuracy. This control device for a plate feeding device includes: a control unit that controls the rotation of a first roll and a second roll of the plate feeding device; a transmission unit that transmits an electromagnetic wave toward a plate; and a transmission unit that transmits the electromagnetic wave toward the plate, wherein the control unit measures the transport speed of the plate during a predetermined period on the basis of the frequency of the electromagnetic wave received by the reception unit, and measures the transport amount of the plate on the basis of the transport speed.

An automated method and machine for fabricating metal fence pickets in a single operation includes forming material, typically metal strip into multiple pickets with various shapes. The machine includes automated programmable machine for inserting raw material to form the metal fence pickets, automated programmable machine for embossing the metal fence pickets, automated programmable conveyor machine for conveying the raw material, automated programmable machine for cutting, punching holes, and folding the raw material to form the metal fence pickets.

A kicker assembly for a tubular handling system has a moving member of a linear actuator that moves between a first position on a fixed member of the linear actuator and a second position on the fixed member. The moving member of the linear actuator is connected to a kicker shoe by one or more connecting members to move the kicker shoe from a retracted to an extended position to move a tubular out of the tubular handling system. The axis of the fixed member of the linear actuator runs substantially perpendicular to the motion of the kicker shoe.

Feed segments within an adjustable feed matrix may be vertically adjusted, horizontally adjusted, and adjusted for rebar thickness. The adjustable feed matrix may be used in rebar structure building. A feed column may include a plurality of feed segments. Each feed segment may include a feed input and a feed output connected by a feed cavity. The feed cavity can include a feed mechanism and/or stabilizing mechanism that allows different thicknesses of rebar to consistently pass through the feed segment to the feed output. A vertical adjustment may adjust vertical spacing of the segments and increase or decrease vertical spacing of the feed outputs, enabling different vertical spacing between rebar passing through segments of the feed column. The feed column may attach to a rail through a coupling. The coupling may be released through a horizontal adjustment, enabling the feed column to slide along the rail and adjust horizontal spacing of the feed outputs.

A forming system forming a metal pipe by expanding a metal pipe material, includes: a main body part having a forming die for forming the metal pipe; an electrode causing a current to flow through the metal pipe material disposed in the forming die such that the metal pipe material is heated; a power supply unit disposed at a position separated from the main body part and supplying power to the electrode; and a power supply line connecting the power supply unit and the electrode, in which the power supply line includes a lower-side passing portion passing through a lower side of a placing surface on which the main body part is placed, a first connection portion drawn to an upper side of the placing surface and connecting the lower-side passing portion and the electrode, and a second connection portion connecting the lower-side passing portion and the power supply unit.

An illustrative example tube handling machine includes a lifter configured to receive a plurality of tubes when at least a portion of the lifter is at a first position. The lifter is configured to lift the plurality of tubes to a second, higher vertical position. A plurality of cells are respectively configured for at least temporarily holding the plurality of tubes. A first one of the cells is situated to receive the plurality of tubes from the lifter at the second vertical position. The cells are situated relative to each other such that the plurality of tubes can be sequentially transferred among the cells from the first one of the cells to a last one of the cells that releases the plurality of tubes to a delivery location.

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.

The present invention is directed to an improved metal strips straightener, including an infeed device and a pressure frame. The infeed device has one or more leveling rollers, and the pressure frame has a roller frame. The roller frame has one or more roller blocks to bring a metal strip into a upward full encirclement wrap. Each roller block is attached with a camshaft, where each camshaft is connected to a motorized drive system. Rotation of the camshafts actuates the roller blocks to move the metal strips, applying pressure on the metal strips during the passing through of the roller blocks. A closing cylinder is attached to one end of a roller block, where the closing cylinder has a convex contact surface. Multiple roller blocks are connected to each adjacent roller blocks via their connected closing cylinders.

Apparatus for handling bars including a support plane configured to support a plurality of bars having an oblong development, and handling devices configured to remove a bar from a removal zone of the support plane and to deliver it to a delivery zone. Movement devices are associated with the support plane which are configured to distribute the bars on the support plane and to move them toward the removal zone.
