A sawtooth wave rises (or falls) in a straight line from a starting point to an ending point, at which time it instantaneously jumps back to the starting value.
锯齿波从某一始点到某一终点沿着一条直线上升(或者下降)，在终点的时候它马上跃迁回其起始值。

The sawtoothline is creased automatically, and the placket, especially for tissue, is cut automatically.
自动压出膜的锯齿线； 自动分切膜的开口（如面巾纸盒）；

A simplified method based on fuzzy weight function is proposed in this paper. 3d taper beam is replaced with line beam in the new method, which can avoid sawtooth phenomenon.
