Slitting is the action of
reducing the parent width of the coiled steel to one or a number of
narrower widths. Each of the finished widths is known as a strand, and
is recoiled to produce a finished width slit coil. The strands can be of
varying width.
To slit the material the
coil is unwound and passed through a set of fixed guides, this allows
for the parent material to be offered up to the slitting head in a
controlled manner. The slitting head consists of two driven arbors with
a number of rotary slitting knives and spacers set to produce the
finished required size once the material has been passed through them.
The blades act as rotary cutters, thus offering a never fully closing
scissor action..
Once the material has
been slit it is recoiled on the finishing mandrel to produce a number of
smaller coils. Other options might include cutting the coils into half
or more and re-slitting to smaller sizes
