Numerous manufacturers now produce high-speed slitting machines and slitting machine production lines in the market. However, due to the overwhelming influence of price factors in the domestic market, product quality varies significantly. Many companies, driven by the desire to capture market share through pricing, adopt a “one order at a time” mentality. They recklessly modify proper design solutions and resort to various methods to cut manufacturing costs, completely disregarding the long-term reliability of the customer's end products.

The essence of constant tension control during winding and unwinding processes lies in monitoring changes in roll diameter during operation. As roll diameter varies, the motor output torque of the split-motor system must adjust accordingly to maintain consistent load operation. For V-series inverters, torque control capability enables effective constant tension control during winding. The V series frequency converter provides three analog input ports: AUI, AVI, and ACI.

During the slitting process on fully automatic high-speed slitting machines, if steel coils are wound in a slack state, slippage occurs between the inner layers of the coil. This can lead to various surface scratches on the steel sheets, as well as rub marks caused by repeated friction at the points where scratches form. In fact, even normally wound steel coils can develop scratches when wound beyond normal tension during operation on fully automatic high-speed slitting machines.

Slitting machines and cross-cutting machines—these two pieces of equipment share a similar name, both used for cutting materials, yet they differ fundamentally. Let me explain each one in detail.

The market offers a wide range of laminating machine products, including: tape laminators, BOPP film laminators, stationery tape laminators, film laminators, backlight laminators, laser film laminators, and kraft paper laminators.
