Definitions
- the present invention relates to a protective arrangement for a cutting equipment for dividing a continuous fiber web, said cutting equipment being arranged in a board or paper machine for manufacturing said fiber web and comprises at least one cutting member for cutting the fiber web.
- the invention also relates to a board or paper machine for manufacturing a continuous fiber web, comprising at least one cutting equipment for dividing the fiber web, comprising at least one cutting member for cutting the fiber web.
- the cutting member generally consists of a water jet delivered from a nozzle. In tail cutting and edge trimming the nozzles are placed relatively close to the paper web. When the thin water jet encounters the fiber web, the water splashes up from the cutting area and forms a water mist while, at the same time, fibers are wrested from the fiber web and carried along with the water mist. Some of these fibers collect on the cutting equipment so that growing aggregations of fibers are arising. In due course clumps of fibers will become detached from these aggregations of fibers and fall down onto the fiber web, and thus they may give rise to web breaks downstream of the cutting equipment.
- Another problem caused by aggregation of fibers on the cutting equipment is that detached fibers are collected on the nozzle around its orifice so that the growing aggregation of fibers will finally detrimentally influence the water jet, thereby deteriorating its task of dividing the fiber web by a continuous slit .
- Additional wrested fibers that may collect on the cutting equipment may also come from the zone where the forming wires diverge from each other and the fiber web is exposed after forming.
- the object of the present invention is to provide a protective arrangement making it possible to substantially reduce, and in many cases practically eliminate the risk of said operational disturbances.
- one or more cleaning members at least one of which being arranged in connection to the outside of the belt member at a distance from said cutting member, to remove the portion of the released fibers being caught by the belt member.
- a board or paper machine in accordance with the invention is characterized in that it includes such a protective arrangement.
- Figure 1 shows schematically a part of a machine section in a paper machine.
- Figures 2 and 3 show schematically in a top view and side view, respectively, parts of a cutting equipment for edge trimming the fiber web in the machine section shown in
- FIG. 1 and provided with a protective arrangement in accordance with a first embodiment of the invention.
- Figures 4 and 5 show schematically in a top view and side view, respectively, parts of another cutting equipment for edge trimming the fiber web and provided with a protective arrangement in accordance with a second embodiment of the invention.
- Figures 6 and 7 show schematically in a top view and side view, respectively, parts of a third cutting equipment for edge trimming to obtain two trimmings and provided with a protective arrangement in accordance with a third embodiment of the invention.
- Figures 8 and 9 show schematically in a top view and side view, respectively, parts of a cutting equipment similar to that shown in Figure 2 for edge trimming from below and provided with a protective arrangement substantially similar to that shown in Figure 2 but inverted.
- Figures 10 and 11 show schematically in a top view and side view, respectively, parts of a cutting equipment for tail cutting a fiber web and provided with a protective arrangement in accordance with yet another embodiment of the invention.
- FIG. 1 shows schematically parts of a paper machine for manufacturing soft paper such as tissue and other creped sanitary paper products.
- the paper machine comprises a machine section in the form of a wet section.
- the wet section comprises a former 1 and a press section (not shown) .
- the former 1 has a headbox 2, an inner, supporting forming clothing 3, an outer, covering forming clothing 4, a forming roll 5 and a breast roll 6.
- the forming roll 5 and the breast roll 6 are arranged near each other so that the forming clothings 3, 4 converge on the forming roll 5 to define a wedge-shaped gap between them before they converge.
- the headbox delivers a single or multi-layer jet of stock into said gap for forming a fiber web 7 by dewatering the stock.
- the two forming clothings 3, 4 run together over the forming roll 5, and then in individual loops over a plurality of rolls 8 and 9, respectively, arranged to drive, guide, direct and stretch the forming clothings 3, 4.
- the wet section is provided with a cutting equipment 10 for dividing the fiber web 7.
- the cutting equipment 10 for edge trimming is shown which comprises a jet-formed cutting member 16 which, in the embodiment shown in Figures 2 and 3, consists of a water jet.
- the cutting equipment 10 thus comprises an edge trimming nozzle 11 with an orifice 22 to produce an edge trimming 12.
- the cutting equipment 10 has a stand 13 rigidly mounted on the machine stand 14, and a supporting arm 15, mounted on the stand 13 and carrying said edge trimming nozzle 11 at its inner, free end.
- the supporting arm 15 extends preferably horizontally in over the clothing 3 and is adjustable in order to set the edge trimming nozzle 11 in the desired position in relation to the fiber web 7 and its side edge or to the side edge of the clothing 3.
- the orifice 22 of the edge trimming nozzle 11 delivers said water jet 16 against the moving fiber web 7, the et cutting through the fiber web 7 so that a continuous, longitudinal slit 17 is formed that divides the fiber web 7 into said edge trimming 12 and an edge-trimmed fiber web 7a.
- Figures 2 and 3 show a first embodiment of a protective arrangement 37 in accordance with the invention, arranged in connection to the cutting equipment 10 and comprising a movable, endless belt member 20 with a straight run 21 situated between the edge trimming nozzle 11 of the cutting equipment 10 and the cutting area 18 at the fiber web 7 and preferably as close to the orifice 22 of the edge trimming nozzle 11 as possible, e.g. 0.0-2 cm.
- the belt member 20 runs in the cross machine direction, preferably perpendicularly thereto.
- the movable belt member 20 is so designed and arranged that it in no way disturbs the function of the edge trimming nozzle 11 in delivering the desired water jet 16 against the fiber web 7.
- the belt member 20 is sufficiently wide to ensure that substantially no part of the cutting equipment 10 is encountered by the water mist 19 containing fibers and rising from the cutting area 18.
- the belt member 20 consists of two parallel belts 23, 24, passing around a common inner roll 25 and a common outer roll 26, said rolls 25, 26 being rotatably journalled in a common stand 27 supported by the machine stand 14.
- the outer roll 26 is driven by means of a motor 28 so that the two belts 23, 24 run at low speed in the direction indicated by arrows.
- the lower and upper horizontal runs 21, 29 of the belts 23, 24 define between them a space 30 sufficiently large to receive the edge trimming nozzle 11 and an inner part 31 of the supporting arm 15, which thus also has a transverse connecting part 32 and an outer part 33 parallel to the inner part 31.
- the inner roll 25 is situated behind the edge trimming nozzle 11 so that the belts 23, 24 run past it on the lower side and upper side, the inner turning point of the belts 23, 24 being situated at a sufficient distance from the edge trimming nozzle 11 so that all, or as much as possible of the water mist 19 containing fibers encounters the belts 23, 24, as regards the extension of the water mist 19 across the fiber web 7.
- an outer cleaning device 34 for cleaning the outside of the belts 23, 24 with the aid of water sprayed onto the outer side of the movable belts 23, 24 in order to remove fibers that get caught on the belts 23, 24 when they pass over the cutting area 18.
- an inner cleaning device 35 in the form of a scraper is provided to clean the inner side of the belts 23, 24 from fibers that may penetrate into the space 30 and accumulate on the inside of the belts 23, 24.
- the belts 23, 24 are arranged to overlap each other at the edge parts facing each other, so that no opening between the edges of the belts 23, 24 facing each other appears before and after the edge trimming nozzle 11.
- the edge trimming nozzle 11 is provided with a gap-opening element 36 extending down between the belts 23, 24 and having a vertical, blade-shaped edge facing against the direction of movement of the belts 23, 24, so that the overlapping edge parts of the belts 23, 24 are separated immediately before the edge trimming nozzle 11 and a gap is formed and maintained between the edges of the belts 23, 24 facing each other as they pass the water jet 16, the gap being sufficiently wide to ensure that the water jet 16 does not come into contact with the edge parts of the belts 23, 24.
- the gap should not be too wide so that fibers are able to pass through the gap and get caught on the edge trimming nozzle 11 near its orifice 22.
- a gap-stabilizing element (not shown) of the same design as the gap-opening element 36 may be arranged immediately after the edge trimming nozzle 11 and with its blade-shaped edge facing in the direction of movement of the belts 23, 24.
- the belts 23, 24 thus have the double function of preventing fibers getting caught and collecting on the cutting equipment 10, resulting in detrimental fiber clumps falling down, and also of preventing fibers getting caught and collecting on the edge trimming nozzle 11 itself, close to its orifice 22, so that this becomes blocked and its function negatively affected, resulting in poorer formation of the slit 17 and division of the fiber web 7.
- Figures 4 and 5 show a cutting equipment 10 with a second edge trimming nozzle 40 carried by a supporting arm 41 mounted on the first supporting arm 15.
- the second edge trimming nozzle 40 is arranged upstream of the first edge trimming nozzle 11, slightly laterally displaced in relation thereto, so that the water jet 16 from the first edge trimming nozzle 11 effects trimming of the edge of the fiber web 7a to make it even straighter than the one obtained with only one water jet.
- FIGs 4 and 5 show a second embodiment of a protective arrangement 37 in accordance with the invention, which is arranged in connection to the cutting equipment 10 and is similar to that shown in Figures 2 and 3 except that the belt member 20 consists of three parallel belts 42, 43, 44.
- the intermediate belt 43 cooperates with the two outer belts 42 and 44 in an overlapping relationship as described earlier for the two belts 23, 24 in Figures 2 and 3.
- each edge trimming nozzle 11, 40 carries a gap-opening element 45, 46 extending between respective pairs of belts 42, 43 and 43, 44 and otherwise being arranged and having the same function as described in conjunction with the first embodiment .
- Figures 6 and 7 show a cutting equipment 10 similar to that shown in Figures 4 and 5, except that the second edge trimming nozzle 40 is arranged inside the first edge trimming nozzle 11 and at a predetermined distance therefrom, in order to provide a second edge trimming 47 by means of a second water jet 48 forming a second slit 49 where more water mist 50 containing fibers is obtained. It should be understood that any number of trimming nozzles or cutting members can be arranged in the cross machine direction.
- the protective arrangement 37 shown in Figures 6 and 7 is similar to the first embodiment described above, however, a second gap-opening element 51 has been added, which is supported by the second edge trimming nozzle 40 and extends down between the belts 23, 24, having the same function as the following gap-opening element 36.
- Figures 8 and 9 show a cutting equipment 10 similar to that shown in Figures 2 and 3 , but arranged on the lower side of the clothing 3 so that the water jet 16 first passes through the clothing 3 and thereafter makes the slit 17 in the fiber web 7.
- the protective arrangement 37 shown in Figures 8 and 9 is similar to the first embodiment described above, except that the gap-opening element 36 is directed upwards to extend up between the belts 23, 24, since in this case the water jet 16 is acting upwards.
- the function of the protective arrangement 37 is primarily to protect the edge trimming nozzle 11 and its orifice 22 so that fibers from the water mist 19 containing fibers do not get caught and collect on the edge trimming nozzle 11, having a detrimental influence on the function of the edge trimming nozzle by wholly or partially clogging the orifice 22.
- Figures 10 and 11 show parts of a machine section provided with a cutting equipment 10 for dividing the fiber web 7, and more particularly for tail cutting in order to provide a tail 60.
- the cutting equipment 10 comprises a tail nozzle 61 with an orifice 62 that delivers a sharp water jet 63 against the movable fiber web 7, said water jet cutting through the fiber web 7 so that a continuous slit 64 is formed that divides the fiber web 7 into said tail 60 and a fiber web 7b which, downstream of the cutting equipment 10, is deflected to a reject (not shown) .
- the cutting equipment 10 is arranged on a stand 65 supported by the machine stand 14 and comprising a transverse beam 66 extending across the fiber web 7, at a predetermined distance above this.
- the cutting equipment 10 is movably mounted along the beam 66 for displacement by an actuator (not shown) from a resting position at and outside the one side edge 67 of the fiber web 7, towards the other side edge 68, to be set in a desired active position at a predetermined distance from said second side edge 68, in order to provide said tail 60 of desired width. It will be understood that the cutting equipment 10 is in operation even while being moved from and to said resting position and the slit 64 therefore has an oblique extension in relation to the machine direction.
- FIGs 10 and 11 illustrate yet another embodiment of a protective arrangement 37, arranged in connection to the cutting equipment 10 and its path of movement, which has a great similarity to the first embodiment of the protective arrangement in accordance with Figures 2 and 3.
- the protective arrangement 37 thus has a movable, endless belt member 20 with a straight run 21 situated between the tail nozzle 61 of the cutting equipment 10 and the cutting area 18 at the fiber web 7 and preferably as close to the orifice 62 of the edge trimming nozzle 11 as possible, e.g. 0.0-2 cm.
- the belt member 20 runs in the same direction as the direction of movement of the cutting equipment 10, i.e. perpendicularly to the machine direction.
- the belt member 20 extends across the entire width of the fiber web 7.
- the belt member 20 consists of two parallel belts 69, 70, passing around two common outer rolls 71, 72 which are rotatably journalled in stands 73, 74 supported by the machine stand 14.
- the stand 74 of the one roll 72 (the right one in the Figures) is movably carried on the machine stand 14 and is provided with a stretching device (not shown) to stretch the belts 69, 70 via the roll 72, as indicated by the arrow 75 in Figure 10.
- the right-hand roll 72 is driven by a motor 76 so that the two belts 69, 70 run at a low speed in the direction indicated by arrows.
- the lower and upper horizontal runs 21, 29 of the belts 69, 70 define between them a space 30 sufficiently large to receive the tail nozzle 61 and the beam 66 .
- the protective arrangement 37 is also provided with cleaning devices (not shown) as described earlier.
- the belts 69, 70 are arranged to overlap each other with their edge parts facing each other, so that no opening between the edges of the belts 69, 70 facing each other appears before and after the tail nozzle 61, regardless of where it may be.
- the tail nozzle 61 carries a gap-opening element 77 extending down between the belts 69, 70 and having a vertical, blade-shaped edge facing against the direction of movement of the belts 69, 70, so that the overlapping edge parts of the belts 69, 70 are separated immediately before the tail nozzle 61, a gap thus being formed and maintained between the edges of the belts 69, 70 facing each other as they pass the water jet 63, the gap being sufficiently wide to ensure that the water jet does not come into contact with the edge parts of the belts 69, 70.
- the gap should not be so wide as to allow fibers to pass through the gap and get caught on the tail nozzle 61 near its orifice 62.
- a gap-stabilizing element of the same design as the gap-opening element 77 may advantageously be arranged immediately after the tail nozzle 61 and with its blade-shaped edge facing in the direction of movement of the belts 69, 70.
- Driving of the belts 69, 70 is started by the motor 76, as soon as or just before the cutting equipment 10 is activated to be moved from its resting position, and is stopped as soon as or just after the cutting equipment 10 has been disconnected after returning to its resting position. Said activation includes movement and also forming of said slit 64. During operation of the cutting equipment 10, some fibers will encounter the outside of the movable belts 69, 70 and then fall down onto the fiber web 7, while other fibers will get caught on the outside of the movable belts 69, 70.
- the belts 69, 70 are in continuous movement, the fibers that got caught on the belts 69, 70, are carried away from the cutting area 18 so that no large aggregations have time to be formed, that might grow to such an extent that detrimental fiber clumps may become detached and fall down onto the fiber web 7. Moreover, the belts 69, 70 are cleaned so that clean surfaces always arrive at the cutting area.
- the belts 69, 70 thus have the double function of preventing fibers getting caught and collecting on the cutting equipment 10, resulting in detrimental fiber clumps falling down, and also of preventing fibers getting caught and collecting on the tail nozzle 61 itself, close to its orifice 62, so that this becomes blocked and its function negatively affected, resulting in poorer formation of the slit 64 and division of the fiber web 7.
- a water jet is used as cutting member
- the protective arrangement in accordance with the invention may naturally be used with a cutting equipment that has other types of cutting members which cause the same problems as described in the introduction, e.g. air jet, laser jet, ultrasound, depending on the location of the cutting equipment in the machine.
- the alignment of the protective arrangement may be varied from the cross machine direction to the machine direction. Furthermore, the protective arrangement may also extend so that it is parallel with the plane of the fiber web, or so that it forms an angle with this.
- the cutting equipment and associated protective arrangement in accordance with the invention can be placed within various machine sections of a board or paper machine.
- the paper machines shown are soft paper machines, but a cutting equipment with associated protective arrangement in accordance with the invention can naturally be used in all types of board or paper machines.
