  • Patent number: 6688218
    Abstract: A calender for treating a paper web, having at least one roll stack capable of being loaded from the end and in each case comprising a top and bottom end roll and a plurality of intermediate rolls, which are jointly arranged in a roll stack plane, and the rolls including hard and soft rolls in order to form operating nips in the form of soft nips, wherein each soft roll which forms an intermediate roll has a greater diameter than a soft roll which forms an end roll.

  • Patent number: 4491283
    Abstract: 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.

  • Patent number: 4347784
    Abstract: 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.
