Each of a pair of opposing slides which is equipped with a die and is connected through a connecting rod to an eccentric portion of a crankshaft is displaced by a width setting device in the direction of width of a slab so as to set the width of a slab to be forged between the pair of dies. After the setting of the width of a slab to be forged, the crankshaft is rotated to cause each of the slider-pair to reciprocate not only in the direction of width of the slab but also in the direction in parallel with the slab transportation line, whereby a slab is forged.

Horizontally opposed-die type edging press

Both an upper blade carried by an upper drum and a lower blade carried by a lower drum or either of them is so arranged as to describe a non-circular locus when shearing is effected.

Method for shearing hot strips and device therefor

Disclosed is a drum type flying shear wherein both or either of blades carried by upper and lower drums, respectively, is caused to describe a part of a non-circular locus whose major axis extends vertically when a blank or hot strip is almost sheared off.

Drum type flying shears

Both of the upper and lower blades carried by the upper and lower drums, respectively, or either of the upper or lower blade is so arranged as to partially describe a non-circular locus having the vertically extended major axis when complete shearing is effected.
