Chali Strapping Machine Press Knife JN740

Chali Strapping Machine Press Knife JN740 – Strong weld pressing, stable operation

Chali JN740 strapping machine press knife is the part that plays the role of pressing the two ends of the belt tightly after the melting heat blade. This is the detail that determines the strength of the weld and the bearing capacity of the package.

If the press knife is worn, misaligned, or the surface is uneven, the weld will be weak, making it easy to unwind when transporting.

Function of Chali Strapping Machine Press Knife JN740

During the strapping cycle of the Chali JN740 machine, after the belt is tightened and heated, the press knife will:

• Squeeze the two ends of the melted wire tightly
• Applying pressure with a cutter helps to cut the belt
• Create strong and aesthetic welds
• Ensuring bearing strength when transporting
• Reduce wire breakage and belt misalignment

The press knife works in sync with the thermal blade and the cutter, thus requiring high precision.
