    摘要： A method for mitigating the effects of coil collapse on hot strip mill coils. A hot strip coil is removed from the mandrel/downcoiler and pre-sagged to create an initial sag by allowing gravity cause the coil to sag in a first specific direction for a first period of time. Then, without coil eye support to limit sagging, the direction of the sag caused by the force of gravity is modified to a direction perpendicular to the first specific direction and gravity is allowed to sag said coil for a second period of time. The first period of time and the second period of time are chosen such that the initial sag created during the first period of time is substantially mitigated by the perpendicular sag during the second period of time. The hot strip coil being cooled enough by the end of the second period of time such that the rate of sagging of the hot strip coil has become negligible.

    摘要： A workpiece conveyor system comprising: a conveyance apparatus which conveys workpieces in one direction, a stopper which is mounted on the conveyance apparatus so as to stop workpieces which are conveyed by the conveyance apparatus at a predetermined position, and a takeout apparatus which takes out workpieces which have been stopped by the stopper from the conveyance apparatus. An outer edge of the stopper in an opposite direction to a conveyance direction of workpieces extends in a curved shape in a transverse direction of the conveyance apparatus.

    摘要： A purpose of the present invention is to provide a fastening head module for coil packaging, which can be manufactured in a small size and light weight, performs an accurate operation, enables convenient maintenance and repair, and guarantees the packaging quality. To achieve the purpose described above, the present invention provides a fastening head module for coil packaging applied to a fastener for steel sheet coil packaging, the fastening head module comprising: a frame including a plurality of plates combined with each other; a correction part arranged on one side of the frame to correct a supplied band by removing the curvature of the band; a feeding part for transferring the band having passed through the correction part, and applying a tension to the band after the band completely winds the coil; a guide part for converting a transfer direction of the band transferred by the feeding part and detecting a tension applied to the band; a grip part for clamping and cutting an end of the band; and a fastening part for fastening overlapped bands.

    摘要： A trailing end of a leading metal strip is joined to a leading end of a trailing metal strip by first overlapping the leading end of the trailing strip with the trailing end of the leading strip and then clinching the ends together at the overlap by pressing at least one punch of a joining tool into one of the strips at the overlap sufficiently to complementarily deform both of the strips. The thickness of the leading and trailing ends is measured and a depth of engagement of the punch into the strips is controlled in accordance with the measured thickness.
