3-in-1 Function Bra Manufacturing Machine:

Seamless Technology: This aspect is used to create bras without visible stitching, offering a smooth finish for comfort and aesthetics. The fabric is molded rather than sewn.

Jelly Glue Application: Jelly glue is often applied to bra cups or straps to provide adhesive properties, helping the bra stay in place without slipping. It can also enhance the durability of the fabric.

Blushing Printing: This might refer to a special printing technique on the fabric or inner lining of the bra, which could be decorative or functional, possibly adding a soft tint or texture.

Such machines are likely used in specialized factories for producing high-quality bras with multiple functions integrated into one process.
