Definitions

  • the invention relates to a reel-up for a paper web presented in the preamble of the appended claim 1.
  • the invention also relates to a roll of a reel-up and to a method in a reel-up for a paper web.
  • the US patent 3,743,199 discloses a reel-up in which the winding of the web around the reel spool in a reel change situation is ensured by using a reel spool whose mantle is perforated by arranging underpressure inside the reel by means of a vacuum pump. It is a problem also in this reel-up that when it is desired to drive the reel in full width through the nip between the reeling cylinder and the reel spool along the surface of the reeling cylinder, the web tends to adhere on the smooth surface of the reel spool, even though a normal air pressure prevails therein.
  • the paper web may slip on the surface of the reeling cylinder. This may occur when the growing paper reel receives its driving force for rotating directly from the reeling cylinder by means of friction. In this case the friction between the paper web and the reeling cylinder is not sufficient and slipping occurs, which causes that the peripheral speed of the reel is slightly lower than the peripheral speed of the reeling cylinder and the speed of the web to be reeled on the machine reel. Because of the speed difference between the reeling cylinder and the reel spool, the tension of the paper web is reduced, resulting in uncontrolled variations in tension and hardness, which cause looseness and wrinkles in the roll and may also cause broke in the after-treatment of the roll.
  • a major factor to reduce friction between the paper web and the reeling cylinder is air being funnelled into the gap between the incoming web and the reeling cylinder.
  • the paper web being very wide (normally at least 5 m) in present machines, air left underneath the paper web cannot escape from between the web and the cylinder. Attempts have been made to eliminate this problem by various methods.
  • the publications FI-74446 and FI-98506 can be mentioned.
  • a perforated suction cylinder having a perforated mantle is used as the reeling cylinder, inside which there is a suction box whose suction zone is arranged in the area in which the web touches the surface of the mantle of the reeling cylinder.
  • the air must be conducted from inside the cylinder through the cylinder shaft to a suction pump.
  • the surface of the mantle of the reeling cylinder is provided with grooves, on the bottom of which there is perforation extending through the mantle.
  • An underpressure is developed inside the cylinder by a suction pump, to which there is a connection from inside the cylinder through one end of the cylinder.
  • the holes induce a pressure loss over the holes in the air passing through the mantle, wherein an underpressure is developed inside the cylinder.
  • grooved reeling cylinders with no suction are used.
  • the purpose is to guide the air by means of the grooves only.
  • Relatively deep and narrow (about. 4 mm x 2 mm) grooves extending in the direction of the periphery in a spiral-like fashion from the centre towards the edges, are used to guide the air, pumped into the gap between the incoming web and the reeling cylinder, between the web and the reeling cylinder and past the reeling nip between the reeling cylinder and the reel.
  • the sharp edges of the grooves must be rounded.
  • a similar grooving has been used, arranged to extend spirally from the centre towards the edges over the whole width of the cylinder and consisting of a shallow and wide (appr. 1 mm x appr. 30 mm) gently sloping "flat" groove.
  • the aim is here to eliminate the drawbacks of overpressure developed in the nip between the incoming web and the reel by letting a suitable quantity of air to enter between the paper layers and by leading out extra air.
  • the drawback of the shallow grooving is that the nip profile becomes com- plex, because the surface of the reeling cylinder has little area that is completely even. Problems may thus occur with thin paper grades.
  • the rolls designed for the reel-ups of a paper web function well in certain situations, but they do not take into account all running conditions or reeling stages. It is a primary defect of the reel spools that their structure is optimal only for particular stages of the reeling process. It is a problem of the reeling cylinder that a grooving which is made once, is applicable only in particular running conditions.
  • the reel-up according to the invention is primarily characterized in what will be presented in the characterizing part of the appended claim 1.
  • the roll for a reel-up according to the invention is characterized in what will be presented in the characterizing part of the appended claim 13, and the method is characterized in what will be preseted in the characterizing part of the appended claim 19.
  • reel-up reel spools equipped with holes in the mantle are used, which reel spools otherwise function in the similar manner as normal reel spools at different stages of the reeling process, in other words they are transferred from a storage of reel spools to initial reeling devices in which they are brought in contact with the web travelling on the surface of the reeling cylinder, whereafter they are transferred to the actual reeling station to lie on the support of the supporting structures.
  • the reel-up is provided with members connected to the holes in the reel spool, the members producing such a force effect via the holes that the surface of the reel spool can be changed from the state of attracting the web to the state of repelling the same.
  • the reel-up can be provided both with an underpressure connection by means of which a suction that attracts the web can be achieved in the holes, and with an overpressure connection by means of which the holes are provided with a blowing repelling the web.
  • Both connections can be located at the end of the reel spool, they can e.g. be coupled to the same connecting piece which can be placed into connection with a shaft rotating in the bearing housing in the end of the reel spool. Inside the shaft, there is a channel leading to the hollow inner part of the reel spool, from which said holes open towards the outer surface of the reel spool.
  • an elastic tubular cover can be placed on top of grooves located in the mantle of the reel spool, into which grooves the aforementioned holes open. From inside the roll, it is possible to affect the shape of the cover in such a way that either grooves in accordance with the grooves of the mantle are formed therein, or the cover forms a smooth outer surface.
  • a corresponding structure can also be arranged in the mantle of the reeling cylinder, wherein it can be changed from the groove-like structure into a smooth one, and vice versa, and furthermore, the depth of the grooves can be affected by the magnitude of the underpressure or by the overpressure.
  • the reeling cylinder which guides the web on the reel can always be adapted to the running parametres and/or to the paper quality to be reeled.

  • Fig. 2 shows the principle of the invention before the transfer of the reel on the reel spool in a side-view
  • Fig. 3 shows the principle of the invention at the transfer stage of the web in a side-view

  • Fig. 6 shows an axial cross section of the structure of a third reel spool to be used in the invention.
  • the reel change in a continuously operating reel-up of a paper web is conducted in a known manner by cutting the web passed to a reel that is becoming full and by guiding the same around a reel spool constituting the core of a new reel, the reel spool being brought in contact with the web.
  • air blasts are generally used, wherein it is possible to utilize partial or full-width mechanical cutting of the web as an aid.
  • a blow from below or from the side of the web is often sufficient for bursting and cutting the web.
  • the reel spool is dimensioned in such a way that it can gather a several meters wide web, e.g. over 5 m in width, around itself to form a machine reel.
  • the paper web Before it is possible to move on to the aforementioned run consisting of repeated reel changes, the paper web has to be first transferred around the empty reel spool in a so-called turn-up blow. Before the turn-up blow, the web is passed in its full width via the reeling cylinder to the pulper for example after tail threading, in which a lead-in strip is first brought through the nip between the reeling cylinder and the reel spool so that it travels down to the pulper, whereafter the web is spread into its full width by means of a diagonal cut.
  • the turn-up blow is conducted with an upper blowing apparatus, a so-called gooseneck, which is brought downward from above with a suitable turning mechanism in such a way that the blow nozzle points towards the surface of the reeling cylinder on top of which the web travels to the pulper.
  • the gooseneck is brought to the operational position in such a way that the nozzle points towards the surface of the reeling cylinder after the nip between the empty reel spool and the reeling shaft.
  • Fig. 1 presents a reel-up which is arranged to reel a continuous paper web W travelling at a particular web speed at the terminal end of a paper or paperboard machine or finishing apparatus for paper or paperboard such as a coater.
  • the reel-up comprises a reeling cylinder 1 arranged to rotate by means of a drive, via which reeling cylinder the web W enters, after a particular sector, in a nip N, which is formed between the reeling cylinder 1 and the reel spool 2 brought against the reeling cylinder.
  • the drawing illustrates a situation in which the web W is passed in full width to a broke handling system, e.g.
  • the reel spool 2 rotates in supporting structures (not shown), such as an initial reeling device, the primary arms of which support both ends of the reel and by means of which the reel spool 2 is later on moved onto reeling rails or onto corresponding supporting structures in which the full paper reel is completed.

  • Fig. 2 shows a reel-up according to Fig. 1 , the operating principle of which can be the same as the one in the reel-up of Fig. 1 at different stages of the reeling, but in which changes have been made which facilitate the act of controlling the travel of the web in different situations.
  • the mantle 3 of the reel spool 3 is provided with holes 3a with a suitable spacing, these holes connecting the hollow inner part of the roll to the outer surface of the mantle.
