Definitions
- the present invention concerns a former head of the kind that includes at least one rotary drum, which at each end is mounted in a bearing gable in which a needle roller is mounted, and which is used for dry forming of fibrous web, where a fibre material mixed with air may be fed by injection into the rotary drum.
- former head where a mixture of fibres and air is injected into the ends of rotating perforated drums. Inside the drums, a needle roller is mounted which is also rotatable, and which keeps the individual fibres floating so that no clotting occurs.
- the former head is disposed over an endless running former wire opposite a vacuum box so that the fibres, under the action of the vacuum, are sucked through the perforation in the drum and fixed on the underlying former wire.
- the known former heads usually there are two drums, where one is rotated in the direction of movement of the former wire and the other is counter-rotated in relation thereto. Alternatively, there may be another number of drums.
- the needle rollers which are provided with radially extending spikes, are usually rotated against the direction of rotation of the respective drums.
- drums have been suspended in bearing gables in a frame supporting the former head, and usually also the vacuum box and the former wire.
- the needle rollers have been supported in bearing brackets disposed beyond the ends of the drums.
- the former heads have a width of about four meters.
- the needle rollers are to rotate with a speed up to 1200-1400 rpm in order to attain desired capacity.
- the drums are normally rotated with a speed of about 200 rpm.
- the perforations in the drum have a design which has been determined from the fibres, used for the manufacturing of the fibrous web or tissue. There is a need for changing the drums so that perforations with suitable shape are used when making fibrous webs or tissues of different types of fibres and/or fibre mixtures. For example, for making paper products or napkin products, cellulose fibres are primarily used which may be mixed with longer binding fibres.
- the drum is composed of at least two partly cylindric, readily separatable segments which are mounted on a bearing ring at each of their ends, the bearing ring projecting from the bearing gable and into the drum, that the drum segments are held together on the bearing ring by a corresponding segmented clamping ring, and that the needle roller is mounted on a bearing bracket in the bearing gable.
- drum Since the drum is made of segments, it is possible to let the needle roller remain on its bearing brackets when replacing the drum. It is only required to open the clamping ring and release the dram segments. These drum segments may be lifted up freely in the interspace between the bearing gables. This or those additional drum segment(s), which is/are not lifted free and which is/are disposed on a downwards facing side of the bearing ring, is/are turned upwards, whereafter they are also lifted free from the bearing ring. After removing the dram segments, it will be possible to place new drum segments, as these are lifted in place on the bearing ring between the two bearing gables. When the dram segments are placed on the bearing ring, the clamping ring is mounted again, whereafter the former head is ready for operation.
- the clamping ring will typically be made of a number of segments corresponding to the number of drum segments, and these segments will typically be provided with clamping surfaces or flanges, needing 1-2 screws for clamping the clamping ring segments together.
- clamping surfaces or flanges needing 1-2 screws for clamping the clamping ring segments together.
- the former head is peculiar in that clamping ring segments, dram segments and bearing rings have means for releasable securing of the clamping ring segments and the drum segments to the bearing rings.
- Such means may preferably be provided in the form of screws passing through holes in the clamping ring segments and drum segments and which are screwed into the bearing rings.
- all clamping ring segments may be separated from each other without any risk of the downwards facing drum segments and clamping ring segments falling down. During dismounting and mounting thus there will be no risk of damaging the drum segments during mounting and dismounting.
- the former head according to the invention is peculiar in that the bearing ring has an outer diameter corresponding to the inner diameter of the drum, that a projecting back is provided on the outer side of the bearing ring, and that the end parts of the drum segments are profiled for forming a groove for accommodating the back of the bearing ring.
- the interaction between the projecting back and the groove with simultaneously serve as secure and correct positioning of the drum segment during mounting.
- clamping ring segments are made with an internal groove which is adapted for accommodating the profiled end parts of the drum segments, a further advantage is obtained by a secure clamping with the end parts of the drum securely clamped between the bearing ring disposed inside the drum and the clamping ring disposed externally on the drum. It is preferred to use a number of clamping ring segments corresponding to the number of drum segments. However, it will also be possible to use different numbers of clamping ring segments and drum segments.
- further segmented clamping rings may be disposed at one or more intermediate positions between the ends of the drum. It is noted that such further clamping rings will be disposed at mutually displaced positions over the length of the drum on succeeding drums. Hereby is enabled a uniform laying of fibres, even if such additional clamping rings are used.
- the need for additional clamping rings will depend on the width of the former head/length of the drum and the dimensions of the drum segments.
- the bearing brackets of the needle rollers are supporting the needle rollers spaced apart from the ends thereof.
- part of the needle rollers may be situated in the bearing gable or outside these bearing gables in the connecting pipes that connect succeeding drams with each other for achieving a circulating flow of fibres through the drams.
- drams made of dram segments it is possible to assemble a drum from segments having different perforations in order thereby to adapt the properties of the product. Thus variation in hole shape and hole size may be performed. However, it will also be possible to compose a drum of drum segments having the same perforations.
- Fig. 1 shows a side view of a former head according to the invention
- Fig. 2 an exploded perspective view of drums and needle rollers for a former head according to the invention
- Fig. 3 an enlarged partial view illustrating a detail in Fig. 2; and Fig. 4 a partial sectional view corresponding to Fig. 3.
- identical or corresponding elements will be designed with the same reference designation and will therefore not be explained in detail in connection with each figure.
- a former head 1 according to the invention.
- the former head 1 is disposed over an endless former wire 2 which is moved according to the arrow 3, so that a fibrous web or tissue 4 is formed at the top side of the former wire 2.
- a vacuum box 5 is provided below the former wire 2, at a position opposite to the former head 1, which a vacuum box 5 is provided which via conduit 6 is connected to a source of vacuum (not shown).
- the former wire is passed around reversing rollers 7.
- the formed fibrous web or tissue 4 is removed from the former wire by means of transfer unit that are known in the art.
- Fibre material mixed with air is supplied to the former head 1 via a pipe 8 for injection at the end of one of two drums 9, 10 provided in the former head.
- the supply pipes 8 are connected to shredding devices in form of hammer mills or other equipment which shreds the fibre material so that individual fibres, or individual fibres containing very few agglomerates, are formed.
- the former head includes two rotating drums 9, 10, each containing a needle roller indicated by 11, 12.
- the fibres fed into the drum 8 is circulated through the two drums 9, 10, as these are connected with transfer pipes 13 at both sides, which are well-known in this type of former head.
- Fig. 2 shows a perspective view of certain parts from the former head 1. It appears that the drums 9, 10 are made of two semi-cylindric segments 9 A, 9B, 1OA, 1OB.
- the drums 9, 10 are mounted on bearing rings 14 (only one is visible) which is projecting from bearing gables 15, 16 at each end of the drums 9, 10.
- the needle rollers 11, 12 at each end is mounted on a bearing bracket 17 (only one is visible) which is disposed in or directly on the bearing gables 15, 16.
- the drum segments 9A, 9B, 1OA, 1OB are secured on the bearing rings 14, using clamping ring segments 18 which are provided as semi-circular clamping ring segments as well.
- Each of the clamping ring segments have a hole 19 that may be aligned with a hole 20 in the associated drum segment for receiving a screw which is used for securing the drum segments and the clamping ring segments on the bearing ring 14.
- Fig. 3 shows an enlarged view illustrating the joining of drum segment 9B and clamping ring segments 18 on bearing ring 14.
- bearing ring 14 has a projecting back 21, and that the end part of the drum segment is profiled for forming a groove 22 for accommodating the back 21. Furthermore, it is seen that the clamping ring segment 18 is profiled with a groove 23 which serves to accommodate the projecting back 21, with the profiling 22 of the drum segment 9B interposed between.
- the clamping ring segments are provided with holes 24 for the reception of screws for joining and clamping the clamping rings.
- FIG. 3 two holes 24 are shown on a clamping face, being threaded holes for receiving screws which are disposed in through-going holes (not shown) in the interacting clamping ring segment.
- countersunk screws are used, so that no projecting parts appear on the cylindric clamping ring.
- the formed clamping rings will clamp the drum around the bearing ring 14 for rotating together with it.
- the bearing ring 14 will be seated in the bearing gable 15 in order to be rotated with a desired speed.
- Fig. 2 shows that the needle rollers are provided with a groove 25 in which they rest upon the bearing bracket 17.
- the bearing bracket 17 is mounted on the side plate of the bearing gable 16. Also, there is provided a bearing bracket for the second end of the needle rollers and drive means for these, so that they are driven with a desired rotational speed in a known way.
- Fig. 4 shows a sectional view through the bearing ring at a position opposite the joint of the clamping ring segments and the drum segments, as illustrated in Fig. 3. It appears that the bearing ring 14 is disposed in the bearing gable 15 where it is seated.
- bearing gables as an integrated part of a machine frame and/or as an integrated part of the vacuum box 5. Furthermore, it is possible to make the bearing gables pressure-tight and to connect these with a pressure source via a pipe connection 26 so that maintaining an overpressure in the bearing gables is ensured.
