s textem

Crop & Cobble shears are start / stop type and are driven either with flywheel mounted pneumatic clutch/ brake or direct DC motor driven. These machines are used in hot rolling to front end, tail end and as well as to segment cutting in case of eventualities. The system provides very close cut length. Our crop cable can be configured with PLC for precise control over the process.

Německy Schopfschere - nůžky na stříhání konců (profilů) = cropping nebo taky crop shear.

"To crop front ends of bars and also to continuously cut the on coming bar into short lengths in case of cobble or mill stoppage."

Z toho se zdá vyplývat, že se střihá v případě "slepení",
německy "Ausbrechen des Walzgutes". Možná "vybočení"

viz definici od Aleše Horáka tamtéž:
An incident when bar that is being hot rolled either jams in the mill guides, resulting in delays to reset the gui

Crop & Cobble Shear: Our range of shears include crop and cobble shear. These are mainly used in hot rolling companies to crop the front end or tail end. That is, it is largely used for segmentation and cutting in case of eventualities. They deliver almost accurate cutting results. These shears have clear working options with easy start/stop operation. They are driven with either flywheel mounted pneumatic clutch/ break or direct DC motor driven. The control through the PLC system.
