Hornung Folding Machine: Industrial Thin-Walled Tube Hemming Machine

Hornung Folding Machine: Industrial Thin-Walled Tube Hemming Machine


Hornung Folding Machine is highly specialized equipment designed to perform precise hemming (folding) of the ends of thin-walled metal pipes by . This process, known as a double fold or edge rolling, is necessary to create a safe, reinforced, and smooth pipe edge, which is crucial, for example, for chimneys, ventilation systems, or any structures where it is necessary to eliminate sharp edges and reinforce the end face of the product.

Purpose and Processing Method  

The main function of this machine is to fold the pipe edge by (Fold Over). This ensures:

  • Reinforcement: Significantly increases the rigidity of the thin-walled pipe end.

  • Safety: Eliminates the sharp edge, making the pipe safe for subsequent installation and use.

  • Preparation for Joining: Creates an ideal basis for subsequent welding, connecting, or sealing operations.

The processing cycle is typically fast and controlled, guaranteeing high repeatability and quality.

Design and Operational Features  
  • Application: Exclusively for thin-walled metal pipes.

  • Processing Type: Edge folding (hemming) by .

  • Integration: The machine can be used as a standalone unit or integrated into Hornung production lines, which include flaring/expanding (W6, DW825) and swaging/beading (TSK) machines.

  • Precision: High precision is necessary to ensure a uniform fold along the entire perimeter of the pipe.
