in accordance with fig1 the arriving paper web 9 first travels through a nip between web tension rollers 8 , then partially wraps around a pope - type reel 10 and is then wound onto a reel spool 11 , producing a wound roll 12 . longitudinal rails 13 serve to support the reel spool 11 with the wound roll 12 . by means of levers 7 and a lift device 7a , the reel spool with the wound roll can be pressed against the pope - type reel 10 . as a result , an adjustable line pressure is produced between pope - type roll and wound reel . a control device 6 determines ( via a control line 6a ) the degree of the line pressure and furthermore via control lines 6b , 6c and 6d , the drives m for the tension rolls 8 and / or the pope - type reel 10 and / or the reel spool 11 . the control takes place , among other things , as a function of the increasing weight or the increasing diameter of the wound roll 12 respectively , for instance by means of a measuring line 6e . the device described in fig1 makes it possible so to vary the line pressure prevailing between the pope - type reel 10 and the growing wound roll 12 that it will be relatively small during a relatively brief initial phase of the winding process and will then be increased rapidly . in addition or as an alternative , the so - called web tension can be varied , this being the web tension in the direction of travel of the web which is set in the paper web 9 by means of the drives . a given web tension can be set , for instance , by a slight difference in speed between the pope - type reel 10 and the tension rollers 8 or another web guide device not shown ( for instance , dry section or glazing rollers ). if the reel spool 11 , as shown , is provided with a so - called central drive , then a small difference in speed can also be set between the wound roll 12 and the pope - type reel 10 . there is the possibility in all cases to briefly set the web tension during the initial phase of each new winding process at a relatively small value , it being rapidly increased thereafter . during this initial phase ( also already during the so - called reel spool change ), the new reel spool 110 is preferably already on the rails 13 . for this , the almost completed wound roll 12 is removed somewhat from the pope - type reel 10 . then the levers 7 are immediately applied against the new reel spool 110 so as to be able from the start to commence with the control of the line pressure to be described . the above - described varying of the line pressure and / or of the web tension , assures that the winding hardness wh in each newly produced wound roll according to fig3 will be relatively slight during a brief initial phase of the winding process but will thereafter be increased very rapidly to a relatively high value . the winding hardness wh can thereafter be reduced again very gradually with increasing web layer thickness sd or be maintained essentially constant or else be gradually increased further , depending on the requirements of the individual case or the type of paper . a similar profile of winding hardness can be obtained upon the winding up of a paper web 9 in a roll cutter according to fig2 . in that case , the paper web 9 is unwound from an existing wound roll 12a having a reel spool 11a . the web travels over guide rolls 23 , 24 and through a longitudinal cutting device 25 onto a first carrier roll 1 which , together with a second carrier roll 2 , forms a winding bed for the developing new wound rolls 12 &# 39 ;. there are also indicated diagrammatically a web guide 26 as web draw - in aid and a compressed air box 27 having a blower 28 for forming a compressed air cushion between the carrier rolls 1 , 2 and the wound roll 12 &# 39 ;. that air cushion serves to reduce the bearing load of the wound roll on the carrier rolls when the diameter of the wound roll 12 &# 39 ; exceeds a given value . there can furthermore be noted a load roller 37 by which the still small wound roll can be pressed ( by means of a pressing device 38 ) against the carrier rolls 1 , 2 . a control device 20 receives signals from a desired value transmitter 29 with respect to the amount of the desired operating speed and via the line 35 a measurement value concerning the instantaneous diameter of the wound roll 12 &# 39 ;. the control device 20 controls , via the lines 30 to 34 , the operating speeds of the unwinding station ( wound roll 12a ), the guide rolls 23 , 24 and the carrier rolls 1 , 2 and also , via the line 36 , the amount of the force exerted by the load roller 37 on the wound roll 12 &# 39 ;. for obtaining the winding hardness profile according to fig3 and at the beginning of each winding process , one either briefly reduces the brake moment at the unwinding station ( wound roll 12a ) and / or one briefly reduces the drive moment at the carrier rolls 1 , 2 relative to the other drives so as to thereby influence the web tension . alternatively , or in addition , one can briefly reduce the pressing pressure ( at 38 ) at the beginning of the winding process . also in addition or alternatively , one can temporarily introduce a brake moment or a relieving force into the sleeves 11 &# 39 ;. this is done via clamping heads ( not shown ) which engage into the sleeves and which are part of a guide device . the wound roll 12a of the unwinding station is advisedly supported , as long as its diameter is very large , by means of a weight relief device 39 . as an alternative to the measures described up to now , the result of which is shown in fig3 or in addition to said measures , the reel spools 11 of the winding machine shown in fig1 can be developed in accordance with one of fig4 to 7 . the reel spool 11a is provided in fig4 with a relatively thick and soft covering 41 which is firmly attached over its entire length to the metal body 40 of the reel spool . the covering is highly resilient and it has a rubber hardness of 50 - 200 p & amp ; j , and preferably 100 - 150 p & amp ; j . another possibility is shown in fig5 . in that case , instead of a covering , there is provided a thin additional outer shell 42 which is attached only at its two ends to the shell of the reel spool 11b so that an annular intermediate space 43 is formed which can be acted on by a pressure medium . the pressure is variable , for instance by varying the drive m of a booster pump 44 . it is advantageous in this case to increase the pressure as a function of the increasing weight of the wound roll 12 ( fig1 ). fig6 shows a detail of a reel spool 11c . in that case , a soft rubber layer 45 is applied to a metal roll body 40 and a hard - rubber layer 46 is applied to the soft rubber layer . the hard rubber layer 46 can also be replaced by a thin metal jacket . in accordance with fig7 the soft rubber layer can be replaced by a tube 47 which is spirally wound onto the roll body 40a and the inside of which is acted on by pressure . upon each winding process and if required , one can ,-- in addition to forming a relatively soft intermediate layer between the wound roll and the core -- counteract the increasing weight of the wound roll at least during the second half of the winding process by means of a large - area relief device . for this purpose , various known devices can be used ; see , for instance , de 44 22 877 . 2 or ep 0 384 533 b1 . additional possibilities are indicated in fig8 to 10 . the essential parts of the winding device shown in fig8 are the following : the arriving paper web 9 , pope - type reel 10 , the reel spool 11 , the wound roll 12 , i . e ., the paper web wound onto the reel spool , longitudinal rails 13 for supporting the reel spool with the wound roll , endless belt 14 for directly supporting the wound roll , and belt guide rolls 15 , 16 , 17 . one roll 15 is mounted rigidly and driveable , and the others rest on swing levers 18 , whereby the guide roll 16 can be displaced on the swing lever for tensioning the belt . a lift device 19 is for lifting the swing lever and thus for pressing the belt 14 from below against the wound roll 12 . when the would roll is full , it is moved away from the pope - type reel , i . e ., towards the right on the longitudinal rails 13 . for this purpose , swing levers 18 and guide roll 16 are swung away . if desired , the belt 14 comes into contact with the wound roll 12 only when the latter has reached a certain size . in fig9 the pope - type reel 10 assumes the function of the driveable belt guide roll 15 of fig8 . an additional tensioning roll 19 for the belt 14 can be displaced approximately vertically . fig1 is a variant of fig8 . the belt guide roll 16 can be swung far upward so that , if required , the belt 14 supports the wound roll 12 from the start and presses the wound roll against the pope - type reel 10 . these embodiments have in common is the fact that a large area relief force is exerted on the wound roll by means of a single endless belt which extends over the width of the machine and travels over guide rolls . as a result of this measure , it can be expected that an even higher percentage of a wound roll will be available as marketable paper than solely as a result of providing a soft intermediate layer .
