4.2 PRINCIPLES OF SINGLE KNIFE SLITTING
Slitting by the single knife method is basically the ability of a circular knife to
displace the slit roll as it enters the log.
Single knife slitting is not a precise science. Slitting results are affected by a
number of factors including:
•
the type of backing (i.e. Polyester/Cloth/Foam)
•
evenness of adhesive coating,
•
tension under which the log has been wound to
•
knife diameter
•
knife sharpness or dullness
•
air or room temperature
While Javelin can recommend settings for different products and widths, the
operator must be aware of the factors mentioned and make adjustments
accordingly.
➢
ALWAYS USE HIGH CHROME HIGH CARBON STEEL KNIVES. CHROME
CONTENT RETAINS THE KNIFE EDGE (DURABILITY) WHILE THE CARBON
IS FOR HARDNESS.
➢
ENSURE KNIVES RUN TRUE
– CHECK WITH A DIAL
INDICATOR.
➢
THE RULE IS TO USE THE SMALLEST DIAMETER KNIFE TO
GET BEST RESULTS
➢
A KNIFE WITH EQUAL BEVEL ON BOTH SIDES MUST ALWAYS
BE USED ON THIS MACHINE.
CAUTION
~ always use cut resistant gloves when handling knives ~
ONLY PERSONNEL CERTIFIED TO SHARPEN AND BEVEL KNIVES ARE TO
OPERATE KNIFE GRINDING FUNCTION
