Abstract
The present invention discloses a manual roll replacing method for a supercalender and a method for making a paper connecting joint thereof. Paper which is pre-reserved in a roller set of the supercalender is in butt joint with a new paper roll under the condition that the supercalender can not carry out the operation of flying connection for roll replacement. When the pre-reserved paper is in butt joint with the new paper roll, a horizontal double faced adhesive tape with high viscosity and aqueous solubility is adopted. A longitudinal single faced adhesive tape reinforcing method guarantees the quality of the butt joint, so the success ratio of operation is guaranteed. After the butt joint is completed, the parameters of the tension of a calender are controlled and switched to the normal mode of the calender. When the joint reaches a coiling part, a pressing zone of the supercalender can be closed to carry out press polish. The whole work flow changes the condition that an old supercalender can only lead the paper or connect the paper in the flying mode. The joint has the advantages of simple manufacture, low cost, easy operation and high success ratio. The operational efficiency of the supercalender is greatly increased in the meantime of lowering the paper damaging amount. The present invention is particularly suitable for the supercalender to carry out the roll replacing operation under the condition that an original paper roll is disconnected.
