    Use and maintenance manual Belt slitter Model: LS-320 ____________________________________________________________________________________________________________________ Operation:  Load the slab with pneumatic shaft inside the slab to be cut, ensuring the measurement of the surplus shaft is spread at both ends. We may then load the slab on the unwinder carriage and once it is inside, close the safety chucks.
  • Page 18 Use and maintenance manual Belt slitter Model: LS-320 ____________________________________________________________________________________________________________________  Always check that the sidewise displacement of the unwinder is at the middle of its range, to ensure it may act in both directions for centring.  Unwrap the slab and free the end in order to proceed to run the belt through the inspection table until using unwinder motor placing the belt between the top and bottom rollers of the bench.
  • Page 19 Use and maintenance manual Belt slitter Model: LS-320 ____________________________________________________________________________________________________________________  Pass the belt coming from the unwinder through the inspection table and place the end of the belt between the passage rollers, just as shown in the photos: If necessary, open and adjust the guides loosening the guides handle.
