A three blade fence post straightening device comprises a first row of at least three rollers and a second row of at least three rollers. An axis of rotation of each of the rollers in the first row may be substantially parallel to each other and an axis of rotation of each of the rollers in the second row may be substantially parallel to each other. A forming profile defined between outer surfaces of the respective rollers of each pair of rollers may substantially correspond to a cross section of a three blade fence post, with forming profiles of each pair of rollers being longitudinally aligned to form a substantially straight path through the straightening device. A drive means may be configured to drive each of the rollers in the first row and/or the second row.

A handheld tool for straightening a cable includes a straightening portion disposed in a housing portion. The straightening portion is configured to define a straightening path that extends in a longitudinal direction through the housing portion, and the straightening portion is structurally configured to engage a fiber cable that extends along the straightening path. The straightening portion is configured to spin freely relative to the housing portion such that the straightening portion is structurally configured to straighten a fiber cable that engages the straightening portion as the fiber cable is moved through the housing in the longitudinal direction. The housing portion is structurally configured to permit access to the straightening path from a direction transverse to the longitudinal direction in order to enhance placement of the fiber cable in the straightening path.

A welded shaped steel manufacturing device for weld-connecting a butt portion of a web member having an end butting perpendicularly against a flange member and thereafter correcting in shape the flange member subjected to thermal deformation caused by heat input during welding, the device includes: a corrective device including flange-member correcting rollers arranged for respective ends of the flange member, each configured to press each end on a web-member side of the flange member so as to correct the thermal deformation over a range of the flange member from each end thereof to the butt portion thereof against the web member, and web-member supporting rollers configured to support a web surface of the web member, wherein the flange-member correcting rollers arranged for the respective ends of the flange member apply independent pressures to the respective ends so as to correct the thermal deformation.

A coiled material passing device is usable to pass a coiled material played out by an uncoiler to a leveler feeder configured to correct any winding curl of the coiled material. The coiled material passing device includes a clamper configured to clamp a starting end of the coiled material played out from the uncoiler, a moving body configured to support the damper, the moving body being movable between the uncoiler and the leveler feeder, and a first driver configured to move the moving body.

A straightening machine (1) for straightening profiles includes a plurality of straightening rollers (3) arranged opposite each other on both sides of a straightening line and forming a straightening path, at least some of the straightening rollers being arranged on vertically extending straightening shafts (4) such that they can be horizontally and/or axially adjusted with respect to a profile that is moved in the straightening path. At least some of the straightening shafts (4) can be hydraulically horizontally and/or axially adjusted.

The invention relates to a straightening machine (1) for straightening an elongated semifinished product with straightening roller elements (6), with a roller table line (3) designed as a conveying section (4), with a stand device (7), which holds the straightening roller elements (6) with respect to the conveying section (4) and comprises a drive-side stand half (17) and an operator-side stand half (18), which is displaceable with respect to the drive-side stand half (17), with a changing device (25) for changing the straightening roller elements (6) and with a changing path (35), along which the straightening roller elements (6) can be moved for changing, in which machine the straightening roller elements (6) are movable on the one hand by means of the operator-side stand half (18) along a first segment (36) of the changing path (35), which extends in a horizontal displacement plane (20), and on the other hand by means of the changing device (25) along a further segment (37) of the changing path (35), which extends in a horizontal changing plane (32), characterized in that the horizontal changing plane (32) is arranged in the region of the physical vertical extent (40) of the operator-side stand half (18).

A straightening device for welding wire is provided with two sets of roll groups, having a plurality of straightening rolls with which bends in a welding wire are straightened by passing the welding wire through the two sets of roll groups. The plurality of straightening rolls configuring the roll groups, are arranged at a predetermined arrangement interval along a passing direction of the welding wire in such a way as to face with each other across a straightening path along which the welding wire passes, and the two sets of roll groups, are arranged so that the directions in which they face across the straightening path are different from each other. By configuring the straightening rolls by small-diameter rollers, adverse effects on the welding wire are suppressed, and the welding wire is straightened finely.
