這種(zhong)控(kong)制對機(ji)器(qi)的(de)任何運(yun)行(xing)速度(du)都必須保持有(you)效，包括機(ji)器(qi)的(de)加(jia)速、減(jian)速和(he)勻速。即使在緊急停車情況(kuang)下(xia)，也應(ying)有(you)能力保證(zheng)被(bei)分切(qie)物不破損。張力控(kong)制的(de)穩定與(yu)否(fou)直(zhi)接關系(xi)到分切(qie)產品的(de)質量(liang)。若張力不足，原料在運(yun)行(xing)中(zhong)產生漂移，會(hui)出(chu)現分切(qie)復(fu)卷(juan)后(hou)成品紙起(qi)皺現象;若張力過大，原料又易被(bei)拉斷，使分切(qie)復(fu)卷(juan)后(hou)成品紙斷頭增多。
