  Web paper composite machine is widely used in the coating and lamination of packaging materials for frozen food, dry food, medicine and daily necessities. It can also be used in the lamination of smooth aluminum foil, glass paper, polyamide, polyethylene, polypropylene and other films.

  Control of winding tension of Web paper composite machine

  Unwinding tension control refers to the tension control between the unwinding roll and the coating roll, and the tension control between the second substrate unwinding roll and the composite roll. During unwinding, the passive constant tension unwinding is adopted. Therefore, in the unwinding process, with the decrease of coil diameter, if the tension is kept basically constant, the magnetic powder brake must adjust the rotation torque to meet the requirement of constant tension.

  At the same time, because the distance between the two sections is relatively short, the setting of the initial tension value should be smaller. It is worth noting that the heavier the coil is. The larger the unwinding tension is, and the wider the film coil is with the same diameter, the greater the tension is.

  Winding tension control refers to the tension control between winding roll and compound roll. During winding, the magnetic powder clutch applies the winding torque to the winding core, and the force is transmitted through the friction between the winding layers, and the tension occurs in the outermost layer, which is the winding tension. The purpose of its control is to make the composite membrane roll into the best state.
