A method of joining strip-shaped sheets includes a support step of placing a support member in contact with a reverse feed direction end of a strip-shaped sheet fed to a pressing machine and a feed direction end of a new strip-shaped sheet, and a joining step of joining the new strip-shaped sheet to the strip-shaped sheet by attaching a tape on the reverse feed direction end of the strip-shaped sheet and the feed direction end of the new strip-shaped sheet, wherein in the joining step, the tape is attached from a side opposite the support member with the support member placed in contact with the reverse feed direction end of the strip-shaped sheet and the feed direction end of the new strip-shaped sheet. The problem of the variation in welding quality encountered when welding thin and wide strip-shaped sheets together is resolved and the strip-shaped sheet is fed smoothly.

A computer numerical control (cnc) bending machine used to bend and then cut a specific programmed profile from a long length of cable comprising: a base, a carriage, a bend head and a saw; the carriage includes a spindle to rotate the cable, the carriage is also able to transport the cable in a linear fashion; the bend head comprises a clamp and a wiper roller and a bend die; after a last bend is formed, the clamp and wiper roller are retracted away from the bend die; the carriage is then able to then transport the cable forward away from the saw, the spindle is then able to rotate the cable out of the plane of the bend, the carriage is then able to transport the cable back toward the saw; the saw is then able to sever the cable such that a last leg length adjacent to the last bend which is shorter than the fixed distance between the saw and the bend die.

A conveying device (4) for conveying rolled bar segments, continuously exiting from a cutting shear (3), comprising at least two conveying channels (10, 11) for conveying the bar segments; at least one separation wall (8) separating a first conveying channel (10) from a second conveying channel (11); and at least one fixed partition (9), provided below the wall (8) and which separates the first channel (10) from the second channel (11); the fixed partition (9) is configured so that, at speed, when a rolled bar is deviated to pass from a direction towards the first channel to a direction towards the second channel, the tail of a first bar segment (30) advances in the first channel (10) by passing below the fixed partition (9), while the head of a second bar segment (31) after the first segment (30) advances in the second channel by passing above the fixed partition.

A plant for producing a structured cross-channel packing element. The structured cross-channel packing element comprises at least two adjacent layers made of expanded metal sheets each comprising periodic deformations. The plant comprises a stretching machine configured to cut and stretch a metal sheet to form one of a plurality of first expanded metal sheets, a calibration machine configured to roll the first expanded metal sheets to a desired thickness, a sheet storage unit configured to directly receive each of the first expanded metal sheets rolled in the calibration machine, a forming machine configured to form each of the first expanded metal sheets to form the expanded metal sheets comprising periodic deformations, and a stacking machine configured to stack the expanded metal sheets comprising periodic deformations to form the structured cross-channel packing element. The sheet storage unit is configured to release the first expanded metal sheets directly to the forming machine.

Embodiments of the invention comprise forming a billet from molten steel and hot rolling the billet to reduce the cross sectional area of the billet. Thereafter, the billet is hot rolled into a lead pass bar having a cross-sectional area comprising a reduced width dimension located adjacent to the center longitudinal axis of the bar. In one embodiment of the invention, the billet can be formed into a lead pass bar having a cross-sectional area in the shape of an hourglass or peanut by feeding the billet through a first set of rolls. After the lead pass bar is formed, it is passed through a second set of rolls in order to form the substantially continuous threaded rebar without longitudinal ribs. The cross-sectional area of the lead pass bar helps to produce a substantially continuous threaded rebar product without longitudinal ribs using standard rebar manufacturing tooling and equipment.

A disclosed forming system is a forming system which expands and forms a metal pipe in a die. The forming system includes a preliminary forming apparatus which preliminarily forms a metal pipe material, a forming apparatus which includes a gas supply unit which supplies gas into the preliminary-formed and heated metal pipe material to expand the metal pipe material and a main body portion to which the die is attached, and a cutting device which cuts at least a portion of the formed metal pipe. The gas supply unit is provided so as not to be disposed on a first straight line which connects the preliminary forming apparatus and the main body portion in a plan view and a second straight line which connects the cutting device and the main body portion in a plan view.
