    摘要: A calender wherein the end portions of the lowermost roll of the roll train was mounted for movement along vertical guide rails on the stand. The lowermost roll is movable upwardly by two upright hydrostatic cylinder and piston units with plungers whose axes are coplanar with the axis of the lowermost roll. When the cylinder and piston units lift the lowermost roll to operative position, shoulders on the bearings abut against stationary stops on the stand and the stops are disposed only at one side of the common plane of the aforementioned axes so that the bearings tend to jam against the adjacent portions of the guide rails as soon as the shoulders engage the respective stops. The jamming action is enhanced if the stops are remote from the aforementioned plane and if the guide rails have T-shaped heads which are slidable in complementary T-shaped grooves of the bearings. The stops are installed at the level of the axis of the lowermost roll.

    摘要: Apparatus which winds a running web onto a driven takeup reel employs a distancing roller which is spaced apart from the outermost convolution of growing roll on the reel and is moved away from the reel at a rate which is proportional to the rate of growth of the roll so that its spacing from the outermost convolution of the roll remains unchanged. A suction generating device is provided to evacuate air from a substantially gusset-shaped space which is defined by the outermost convolution of the growing roll and the web portion which advances from the distancing roller to the roll. This reduces the likelihood of entrapment of air between neighboring convolutions of the roll on the takeup reel. The likelihood of entrapment of air is further reduced by wiping air off one side of the web in the region of the distancing roller, by wiping air from the outer side of the outermost convolution of the roll upstream of the gusset-shaped space, and/or by causing a roller to bear against the outer side of the web immediately downstream of the locus where successive increments of the running web reach the roll.

    摘要翻译: 将运行的卷材卷绕到被驱动的卷绕卷轴上的装置采用隔离辊,该隔离辊与卷轴上的生长辊的最外卷绕间隔开,并且以与辊的生长速率成比例的速率从卷轴移开 使得其与卷的最外卷积的间隔保持不变。 抽吸产生装置被设置成从基本角撑板形的空间排出空气,该空间由生长辊和从间隔辊前进到卷筒的腹板部分的最外圈定义。 这降低了在收卷卷轴上卷的相邻卷圈之间夹带空气的可能性。 通过在隔离辊的区域中从纸幅的一侧擦拭空气,通过从角撑板状空间的上游的最外侧的卷绕的外侧擦拭空气来进一步减少空气的捕获的可能性,和/ 或者通过使滚子紧紧地紧紧地紧紧地紧紧地连接到卷筒纸的连续增幅的位置的下游的幅材的外侧。
