摘要： The dry end or dryer section of a paper making machine has a plurality of dryer groups. Each dryer group comprises a plurality of heatable dryer cylinders, reversing rolls between each pair of the dryer cylinders in the group and an endless web support belt which passes over a dryer cylinder and then a reversing roll and then the next dryer cylinder in turn in the group. Between the last two dryer cylinders with which the lower side of the web comes into contact, there is an auxiliary guide roll over which the support belt travels free of the web, while the web travels directly from the selected dryer cylinder to the next reversing roll. Alternately, the auxiliary guide roll is disposed between the reversing roll and the next dryer cylinder in the web path of travel. Between the dryer cylinder and the auxiliary guide roll can be provided a second auxiliary guide roll which presses the web against the belt before the web separates from the web to pass to the auxiliary guide roll. A tip cutter is arranged on the free or unsupported stretch of the web. Other reversing roll arrangements are disclosed for separating the web from the support belt so that the tip cutter can act on the free stretch of the web.
