This paper analyses an isothermal calendering for an upper convected Jeffery’s Material. Lubrication Approximation Theory (LAT) is applied to simplify the flow equations. Analytical solutions of velocity, flow rate, and pressure gradient are carried out. Outcomes of sheet thickness, detachment point, roll separating force, power input to the roll, and pressure distribution are obtained. The effects of some involved parameters are displayed through graphs and tables. It is noted that the material parameter is a controlling device for sheet thickness, flow rate, detachment point, roll separating force, power input, and the pressure distribution. We observed that as the material parameter increases, the detachment point increases which results in increased sheet thickness.

本文分析了一个对流的杰弗里材料的等温压延。润滑近似理论（LAT）用于简化流动方程。进行了速度，流速和压力梯度的解析解。获得纸页厚度，分离点，卷分离力，输入到卷的功率以及压力分布的结果。通过图形和表格显示某些涉及参数的效果。注意，材料参数是用于片材厚度，流速，分离点，辊分离力，功率输入和压力分布的控制装置。我们观察到，随着材料参数的增加，分离点增加，这导致板材厚度增加。
