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.
