Working principle:

Two kinds of power are required to operate a straight knife

    Ø  Motor power drivers the reciprocating blade.

    Ø  Operator power drivers the knife through the lay.

        Motor power needed:

    Ø  The height of the lay.

    Ø  The contraction of the driver.

    Ø  The stroke of the blade.

The greater power of the motor the heavier will be the machine. The standard, the thicker its cross section and the greater its width. The greater the blade movement the faster the blade cuts fabric and the more rapidly and easily the operator and can Puch the machine. Operator affected by the shape of the standard, handle height and the effect of the base plate rollers on the table surface.

Advantage:

     Ø  High production cutting m/c

     Ø  Possible to cut fabric directly

     Ø  High cutting speed

     Ø  Comparatively cheap

Disadvantage:
