FLIEGENDE SCHERE FUER SEHR HOHE LAUFGESCHWINDIGKEIT.

摘要

Very high speed flying shears (10) which is suitable to shear rolled stock (18) travelling even at more than 100 metres per second and comprises two knives (14) with blades (17) able to contrarotate in relation to each other at a pre-set speed at least in the transient period of shearing and is equipped with a guide (11) able to move sideways (19-119) at a pre-set speed (V) and to position itself in a defined position in relation to the circumferential position of the blades (17), an inner dividing wall (27) being located downstream of the knives (14) in a conveyor channel (13), in which shears (10) during the transient period of shearing: - the speeds (VR) of lateral movement of the guide (11) and of rotation of the knives (14) are correlated, and - the lateral position of the guide (11) and the circumferential position of the blades (17) of the knives (14) are strictly interdependent.
