In a method of and a system for unpacking bales each tied by at least one strap, a contact plate member provided with a strap sensor unit is mounted, through a biasing arrangement, on a body frame for movement relative thereto. The body frame is moved toward a confronting side face of the bale to bring the contact plate member into contact with the side face of the bale. The body frame is further moved toward the bale while increasing biasing force of the biasing arrangement, until contact pressure, with which the contact plate member is urged against the side face of the bale, reaches a predetermined value. When the contact plate member is urged by the bale in such a direction as to increase the biasing force during scanning of the strap sensor unit along the side face of the bale, the body frame is moved away from the bale to maintain the contact pressure at the predetermined value. When the strap sensor unit detects a position of the strap of the bale, the body frame is moved to bring a strap handling unit such as cutter or clamps mounted on the body frame, into engagement with the strap.

Bale unpacking method and system therefor

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

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.

Drum type flying shear
