The proposed slitting line will function as longitude cutter to
slit jumbo coils into baby coils for final usage. In the beginning,
jumbo coil is loaded on the coil car by overhead crane and brought
to the decoiler by operating the coil car. Coil car centralizes the
coil under decoiler's mandrel and the coil is mounted on the
decoiler. Mandrel is expanded. Snubber roll rotates the coil.
Peeler breaks the straps and brings the pre end upto Pinch roll.
The Pinch roll drives the coil end upto the slitter. Then its drive
is disconnected. Slitter moves the slitted strips further. Slitted
strips are threaded through loop table and drag tension station
into the recoiler's drum. Recoiler winds one turn on loose
coil.Then drag tensioner and loop are put into operation. Slitter
and recoiler run simultaneously in synchronization. As the coil
build up, the recoiler rpm correspondingly goes down to keep
desired constant line speed. This process goes on until the end of
coil on decoiler. The slitted coil is pushed on the exit coil car
trolley through a pusher plate operated by hydraulic cylinder. The
side slitted scrap is wound on the scrap winder units provided on
both sides of the slitter.
