Definitions
- the invention relates to a method according to the preamble of claim 1.
- a partial-web windup can be a windup of carrier roll type in which the partial web rolls are wound supported by carrier rolls by means of a winding nip between the forming web roll and a second carrier roll.
- the second carrier roll can be a set of belt rolls in which an endless belt loop is arranged around two rolls.
- the partial -web windup can also be a centre-driven windup in which the partial web roll is rotated from the centre and winding takes place by means of the nip between the forming web roll and the winding drum.
- the joint between the web ends is formed in a known manner perpendicularly in relation to the longitudinal direction of the web, which can cause problems in handling rolls in a printing machine and other further-processing devices when the joint being thicker than the other web goes simultaneously full-wide e.g. through a nip.
- the object of the invention is to provide a method in which the above-described disadvantages related to the machine-roll change have been eliminated or at least minimised.
- An object of the invention is to provide a method using which is provided a joint suitable for further processing, e.g. a printable joint.
- a method according to the invention is mainly characterised by what is presented in the characterising part of claim 1.
- the speed of the slitter-winder is decelerated to creep speed and, when the slitter-winder decelerates, the emptying machine roll is transferred away from the unwinder as it is still unwinding, and a new machine roll is transferred to the unwinding position, and the web end of the new machine roll is brought to a joining position into connection with a joining apparatus the old machine roll still unwinding, and the web speeds are adjusted uniform.
- the slitter- winder operates at creep speed, the web ends are joined together.
- the slitter- winder can be stopped for a very short while i.e. only for the time of the joining end travelling across the web and making a joint splice. About 10-30 seconds is passed in this. Also in this case, the time-saving is great compared to methods used today.
- a joint is provided which is not perpendicular in relation to the longitudinal direction of the web but oblique, whereby the joint causes no problems in printing machines or other further-processing devices and the joint splice is thus suitable for further processing.
- Into connection with the slitter- winder are arranged means for transferring the old machine roll during deceleration away from the new machine roll, means for transferring the new machine roll to the unwinding position, means for bringing the web end of the new machine roll into the joining position, and an arrangement for joining at creep speed. Joining the web ends can be performed with joining means known as such whereby is provided a joint suitable for further processing.
- FIG. 1 schematically shows a situation in which a machine roll on an unwinder is just emptying.
- Fig. 2 schematically shows a situation in which an old machine roll is transferred from an unwinding position to a change position.
- Fig. 3 schematically shows a situation in which a new machine roll is brought to the unwinding position.
- Fig. 4 schematically shows a situation in which the web end from the new machine roll is guided to a joining position.
- Fig. 5 shows a situation in which the ends of the old web and the new web are joined and the web coming from the old machine roll is cut.
- Fig. 2 schematically shows a situation in which the old machine roll 10 is transferred to the change position and the web WlO is still unwinding from the old machine roll 10 via a guide roll 28.
- the web pick-up device 20, the counter part 26 of the joining end and the guide roll 27 of the web are transferred to the stand- by position.
- a new machine roll 15 is transferred to the unwinding position, and with the suction roll 21 of the web pick-up device 20 the web end coming from the new roll 15 is picked up, after which the web pick-up device 20 is started to transfer, as shown with arrow S 15, towards the joining po- sition.
- the web being guided to the slitter-winder is still unwinding from the old machine roll 10.
- the joining of the end of the web Wl 5 coming from the new machine roll 15 is performed to the web WlOA coming from the old machine roll 10 with a joining end 25, in which connection the web WlO coming from the old machine roll is cut and the winding continues from the new machine roll 15.
- the joining as such can be performed by applying arrangements known as such for those skilled in the art in which the joining end, when moving across the web, cuts the webs and a joint splice is made between the ends of the webs Wl 5 and WlOA intended for joining.
- the joining end 25 transfers during joining in the cross-machine direction and, when moving, cuts both webs, guides the extra tails aside and pulls tapes to the joint on both sides of the web.
- the joining position is opened by transferring the guide roll 27 and the counter part 26 of the joining end towards the change position.
- tape tails possibly remaining on the edges of the web are cut away in connection with the cutting of edge trims performed later in the process.
- the slitter- winder is accelerated to run speed and the cutting of the partial webs and the winding of the partial webs is continued at run speed.
- the emptying i.e. old machine roll 10 is transferred away from the new machine roll 15 to an upper position, and simultaneously the web pick-up device 20 is transferred to the change position, and the new machine roll 15 is brought to the unwinding position.
- the slitter-winder operating at creep speed the end of the new web Wl 5 is picked up with the web pick-up device 20, e.g. a suction roll beam or e.g. with the suction roll 21 of the web pick-up device 20, and is brought to the joining position into connection with the web WlO coming from the old machine roll 10.
- the webs W15, WlOA moving at creep speed are joined together with the joining end 25, and the web WlO coming from the old machine roll 10 is cut.
- the slitter- winder can be stopped for the time of the across movement of the joining end.
- the joint formed is oblique in relation to the longitudinal direction of the web. After joining, the speed of the slitter- winder is increased to run speed for continuing normal run.
- the joining devices comprise, known as such from prior art, a frame and the joining end 25 and the counter part 26 of the joining part.
- the frame consists of a machine-wide beam with its end structure. Furthermore, into connection with the frame are arranged the guide rolls 27, 28 for guiding the new web and the old web for joining in the joining position.
- the joining part comprises a guide guiding the travel of the joining end 25, the transfer devices of the joining end and the cutting blades of tape.
- the counter part 26 of the joining end is transferred to the joining position against the frame beam by means of an actuator, e.g. a hydraulic cylinder.
- the joining end comprises rotating disc blades which cut the webs being joined during the movement of the joining end.
- the joining end guides the extra web tails aside and the web ends being joined against each other and tapes them together from both sides of the webs forming a so-called butt-joint.
- the joining end there are reels for the tape rolls and for collecting the back tapes of the tape.
- the cutting blades of the tape are located at both ends of the joining beam for cutting the tape.
- a suction roll or a corresponding means the new web is picked up from the surface of the new machine roll and the fasten- ing of the web on the suction roll takes place by means of a vacuum zone provided with the suction roll.
- the suction roll is provided with an actuator, e.g. a hydraulic cylinder, and into connection with the roll is arranged means for rotating it and the roll can be rotated in both directions.
