There are many uses for Shears in coil processing. A shear is used to crop the tongue off a coil on an entry or exit end of a slitting line, cut to length line, pickling line, or galvanizing line, used on the entry end of a tube and pipe mill before material is welded together then fed into an accumulator, and used to cut material into sheets on a cut to length line. Shears are pneumatically, hydraulically, or mechanically operated. Popular types of shears in a cut-to-length line are straight cut shears, rotary shears, and flying shears.
