The edge folding machine, in addition to folding edges, can also join two fabric pieces together. After the fabric undergoes ultrasonic cutting and welding, reinforcement strips need to be applied to the junction to enhance its strength. Here is a description of the process:

- Fabric Joining: Firstly, use the edge folding machine to accurately join two fabric pieces together according to the design requirements. This step typically involves positioning and aligning to ensure the accuracy and stability of the joint.
- Ultrasonic Cutting and Welding: Perform ultrasonic cutting and welding on the joint to achieve a tight fabric connection. This process utilizes the heat generated by ultrasonic vibrations to melt the edges of the fabric together, forming a strong bond.
- Attachment of Reinforcement Strips: After completing the ultrasonic welding, reinforcement strips need to be applied to the junction. Reinforcement strips are usually made of high-strength and wear-resistant materials such as rubber, plastic, or fabric with a special coating.
- Positioning and Adhesion: The automation features of the edge folding machine can be utilized to precisely position the reinforcement strips. Then, using adhesive or other appropriate attachment methods, firmly adhere the reinforcement strips to the fabric joint.
- Compression and Curing: Ensure that the reinforcement strips have full contact with the fabric surface, and perform a certain level of compression to facilitate the complete curing of the adhesive, ensuring that the reinforcement strips are securely attached to the fabric.
This reinforcement strip application process helps to improve the strength of the joint, preventing wear or breakage of the fabric due to stretching, friction, or other stresses.
