Band Knife Cutting Machine:
Band knife cutting machine is an endless and looks like a loop. It is used for the cutting of fabric rolls without cardboard-inner tube. The band knife machine is used to cut small and complicated shape components. It is important instrument of cutting fabrics. This cutting machine works automatically according to the height of the relevant material. This machine is with special blower decreases resistance between fabrics and table, which enables the fabrics be moved easily and be cut precisely. And it could adjustable speed to fit different fabrics. Band knife cutting machines have been recognized around the world for many years for their high quality even when faced with difficult customer-related conditions and in applications with demanding materials.

Band knife cutting machine provides the most accurate cutting and are therefore used in cutting small components of complex shape. The fabric plies are guided against the cutting device that is fixed and performs only a vertical movement down to the fabric. Because the band knife moves in only down direction, the friction between the knife and material ensures the continuous compression of fabric plies throughout the process. Band knife machines may be used to cut fabric spreads up to 300 mm high.

The band knife machine has the following main parts:

  1. Bodywork,
  2. Band knife,
  3. Motor,
  4. Work surface, and
  5. Knife sharpener.

  3. Automatic grinder grind the knife instantly
  4. Air blower helps to reduce the fabric weight which increases smooth movement of fabric.
  5. Possible to cut 90° angle of the lay.
  6. Intensity of accident is low.

Disadvantages of Band Knife Cutting Machines:

  1. Not suitable for large component due to the length of the table.
  2. Work load is high as machine is stationary and fabric is movable.
  3. Running cost is higher.
  4. Required fix space.
  5. Not possible to cut fabric directly.
  6. Block pieces of fabric required in bundle form to cut by this machine.
