Scope

Scope: This standard applies to solventless laminating machines for laminating aluminum foil with other rolled metal foils, rolled films, and rolled papers as substrates; Main technical content: Solventless laminating machines for aluminum foil are generally composed of a unwinding unit, a coating unit, a laminating unit, and a winding unit, and are equipped with a tension system and a numerical control operation system. They are combined with auxiliary devices such as glue applicators (automatic dual-component adhesive mixers or single-component adhesive automatic supply machines), heating machines, and cooling machines. The machine operates at a speed of 100~500m/min. Empty-run quality: In the state of no material and no coating, the machine should run smoothly without abnormal noise, with normal lubrication and normal temperature rise of running parts. Material-run quality: In the state of material presence and no coating, the machine should run smoothly without abnormal noise, with normal lubrication and normal temperature rise of running parts. Coating quality: In the state of material presence and coating, after the machine starts running normally, the actual coating quantity and the target coating quantity should have an error of ≤5%; the coating uniformity in the left, middle, and right three zones should have an error of ≤2%. Tension control: - Torque-based tension control: The deviation between the feedback tension and the target tension should be ≤±0.5kgf. - Angle-based tension control: The deviation in the angle during operation should be ≤±3°. Unwinding quality: In the state of material presence and coating, the substrate should be unfolded evenly without wrinkles or slippage during normal operation of the machine. For substrates with flatness deviations of ±10mm, the automatic correction system should stabilize the deviation to ≤±1mm. Lamination quality: In the state of material presence and coating, the laminated product should
