1. , a kind of method, wherein continuous polymerization plate plate (4) by one by the grooved roll (9 that is meshing with each other, with 10, the horizontal tentering operation of carrying out 11) stretches, in roll, each line of rabbet joint roll twist or garden shape extend and comprise a pedestal (6), at the tooth top (7) of each side with extend to the flare sidewall (5) of tooth top from pedestal, sheet material is therefore by extending transversely, pleat along machine direction is arranged on it basically, the characteristics of technology show that adjacent tooth top spacing is less than about 3 millimeters, the sidewall of intermeshing groove has the part that is parallel to each other, sheet material mainly is extruded between every pair of described substantially parallel sidewall sections by roll is pressed to together, to realize stretching by associating tentering and extruding.
