Bite machine, also known as bone roller machine, seam biting machine, edge biting machine, air duct bite machine, air duct bone roller machine, upright bite machine. It is a multifunctional machine mainly used for bite processing of metal sheet connections and closed connections of circular air ducts.

Can meet various bone shapes for duct manufacturing. The thickness of the processed sheet metal is 0.5-1.5mm. All gears, shafts, and rollers of the machine are made of high-quality steel and undergo strict heat treatment processes to ensure mechanical durability, stable quality, easy installation, beautiful appearance, reasonable mechanical principles, flexible movement, and easy operation and use, which can meet the different requirements of users. The bite machine is suitable for the production of air ducts for ventilation, air conditioning, purification and other devices. According to requirements, it can be made into various square and rectangular thin plate air ducts, and is an indispensable mechanized equipment for various sheet metal processing and air duct production.

Bite machines are divided into multifunctional bite machines, combined corner bite machines, insert bite machines, flat bite machines, elbow bite machines, and upright bite machines.
