Definitions

  • the invention relates to embossing of paper products, for example, paper towels, toilet tissue and napkins, in which an improved embossing combination provides for more efficient manufacture and a more consistent and desirable embossed product.
  • Paper products such as paper towels, napkins and toilet tissue are widely used on a daily basis for a variety of household needs.
  • Such products are formed of a fibrous elongated web which is either packaged in rolls or in a folded stack.
  • the fibrous webs are usually embossed to increase the bulk of the tissue and to improve the absorbency, softness and appearance of the product both as individual sheets, and in providing a uniform stack or roll package. Embossing can also aid in holding superposed plies of a web together.
  • the embossing apparatus will include one or more rolls having male protuberances thereon for forming the embossed pattern, and a corresponding back-up roll which holds the web against the male embossing roll such that the embossed pattern is imparted to the web as it passes between the nip of the male roll and the backup roll.
  • a fiber roll was utilized as the backup roll, with the fiber roll formed of a hard cloth material.
  • the male roll was formed of metal and included the protuberances engraved thereon. Prior to use of the rolls for embossing, the male roll and backup roll were run together (without a web passing therebetween), with soap and water utilized for lubricating and softening purposes.
  • the male roll and backup roll would be run together until the fiber backup roll took on the female pattern corresponding to the protuberances of the male roll.
  • the use of the rolls in embossing of paper products did not begin until after the female pattern or indentations corresponding to the male roll were achieved. Generally, this would require 24-36 hours of operation.
  • the fiber roll approach required a great deal of initial start-up time and cost associated with operating the rolls without embossing web products.
  • male protuberances are provided on a steel male roll, and corresponding female indentations are engraved in a female backup roll.
  • the male protuberances emboss the web, and are accommodated by the grooves or indentations in the female backup roll.
  • a clearance of .003-.007 inches must be provided. Due to the required clearance, the steel to steel approach is not as successful (as other approaches, e.g.
  • the steel roll In rubber to steel embossing, the steel roll is provided with the male protuberances and the web is squeezed against the male roll by a rubber backup roll, as the web masses through the nip.
  • the rubber accommodates the protuberances by virtue of its resilience, and the rubber flows about the protuberances as force is applied to urge the rolls together.
  • an extremely large amount of force is required.
  • the desirable lengths of such rolls has increased to 80-130 inches in length and sometimes even higher.
  • An extremely large amount of force is required to urge such lengthy rolls together, while ensuring the rubber flows about the protuberances.
  • the roll may deflect or bend, such that acceptable rubber flow is achieved at the ends, but not in the center portions of the roll.
  • a steel embossing roll having a plurality of male protuberances extending therefrom, with a mated rubber backup roll urging the fibrous web substrate against the male embossing roll, thereby imparting a highly defined embossed pattern to the paper substrate, for forming paper towels, napkins, or tissues.
  • the web is forced about the male protuberances, and against the land areas of the steel roll, as well as into the indentations and outer peripheral surfaces of the rubber roll.
  • a highly defined embossed pattern is provided, and the sheet is softened due to the fracturing of the fibers as the web is pinched between the rolls.
  • the inventor has recognized that a laser may be utilized for burning away selected portions of a rubber roll, thereby providing a mated rubber roll having indentations corresponding to the protuberances of the male embossing roll. Due to the female indentations in the rubber roll, significantly less pressure is required (between the male and female rolls) for causing the rubber to press the web about the protuberance and against the land areas of the male roll. Thus, the problems associated with wear, particularly heat related wear, of the prior art rubber to steel embossing devices are avoided.
  • Figure 1 is a side view of a conventional rubber to steel embossing arrangement.
  • Figure 2 is a frontal view of a pair of embossing rolls, and illustrates the problem of deflection.
  • Figure 3 is a side view of a rubber to steel embossing arrangement in accordance with the present invention.
  • Figure 4 illustrates a rubber to steel mated embossing arrangement in which two pairs of embossing rolls are provided.
  • Figure 5 illustrates a three roll arrangement in which two embossing operations are performed.
  • Figure 6 illustrates the formation of a mated rubber roll for use in mated rubber to steel embossing in accordance with the present invention.
  • a pair of feeder or drawing rolls 10,12 are provided to draw the web from a supply, typically a large stock roll often referred to as an unwind roll (not shown).
  • the rolls 10,12 are typically on the order of six inches in diameter, and have a knurled surface to aid in grasping the web, to draw it from the stock roll and pass it to the embossing rolls in the direction shown by arrow A.
  • a belt arrangement is also conventionally utilized for feeding the web from supply rolls (or parent rolls) with the belt engaging the outer periphery of the supply to assist in paying out the web from the supply.
  • the embossing station includes a pair of rolls 14,16, which are urged together to form a nip 18 through which the web 11 passes to emboss the web.
  • roll 14 is a steel roll having a plurality of protuberances shown representatively at 20.
  • the protuberances shown in Figure 1 are exaggerated in comparison to the size of the rolls.
  • the protuberances extend on the order of .004-.080 inches from the surface of the roll.
  • the roll will include many more protuberances than that shown in Figure 1.
  • the protuberances may be of any desired shape, such as a simple rectangular shape for providing numerous small rectangular embossments on a web, or somewhat intricate designs or patterns, to impart floral or other decorative designs embossed into the wen.
  • the roll 16 includes a surface formed of a resilient material such as rubber, to accommodate the protrusions of the steel roll 14.
  • the length of the rolls have increased to improve the output or production capacity. While older embossing stations have utilized rolls of 80 inches or less in length, the trend with newer embossing stations has been to utilize rolls in excess of 100 inches, and even 130 inches or greater. Particularly where longer rolls are utilized, the problem of roll deflection reduces the ability of the rolls to provide a consistent highly defined pattern across the width of the web (or along the length of the rolls).
  • Figure 2 shows a frontal view of the embossing rolls 14,16, with the protuberances of the steel roll omitted for clarity.
  • An hydraulic system is provided in the form of hydraulic cylinders 22,24, 26,28 for urging the rolls toward one another, to allow the rubber to flow about the protuberances.
  • the hydraulic cylinders apply force to the shafts 30,32 (through suitable bearings) at the outer portions or ends of the rolls to urge the rolls together. Since the forces are applied at the ends of the rolls, the rolls may tend to deflect at central portions of the roll as shown somewhat exaggerated at 34 in Figure 2.
  • the rolls will deflect more in the center, since the central portions are remote from the application of the forces by the hydraulic system, such that the pressure or force is insufficient to cause the rubber to flow about the protuberances of the steel roll 14.
  • the deflection of the rubber will be much greater than that of the steel roll, and the deflection of the steel roll may be negligible.
  • extremely large rolls are required, typically on the order of 20 inches in diameter. Such large rolls can be extremely expensive, both in terms of initial cost and in terms of maintenance costs, particularly since the tremendous wear on the resilient roll 16 necessitates frequent repair or replacement.
  • feed rolls 17,19 feed the web 11 to downstream processing stations, which typically include a device which perforates the web across its width, with the web then rolled on a mandrel and cut into individual roll-sized units.
  • the perforations aid in removing a desired quantity of the paper product from a roll, and also aid in attaching two or more plies together where the fibrous web comprises multiple plies.
  • a second roll 54 is provided having a resilient outer surface with female portions or recesses 56 provided corresponding to the embossed pattern of the protuberances 52, such that as the rolls 50,54 are in rolling engagement, the protuberances 52 of the rigid roll enter the recesses 56 of the resilient roll.
  • the rigid and resilient rolls thus cooperate to form the embossed pattern on the web.
  • the recessed areas 56 are preferably formed of substantially the same size or even slightly smaller than the protuberances 52; however, the clearance associated with steel to steel mated embossing is not necessary, since the surface of the roll 54 can deform about the protuberances.
  • the advantage of conventional rubber to steel embossing is realized in utilizing a resilient roll which can flow about the protuberances on the rigid roll to work the fibrous web and thereby soften the web while producing a highly defined pattern.
  • the resilient roll includes the recesses, the extremely high pressures associated with prior art rubber to steel embossing is not necessary for causing the resilient rolls to flow or mold about the male protuberances. As a result, the heat generated as a result of the rolling contact and the repeated deformation of the rubber is significantly reduced.
  • the rolls 50,54 may be formed much smaller than those typical in the prior art. In fact, rolls for use in the present invention may be made even smaller than 12 inches diameter, and even as small as six to eight inches in diameter.
  • An hydraulic system may be provided as shown schematically by cylinders 58,60, to allow for separation of the rolls, for example, to allow initial feeding and registration of the web between the rolls, and to urge the rolls together for the embossing operation.
  • the force required for sufficiently urging the rolls together is much lower. Since the required force/pressure between the rolls is less and since the mass of the rolls can be much less, a much less expensive hydraulic system and mounting arrangement can be utilized.
  • the rolls may be mounted and utilized as feed rolls.
  • the rolls may draw the web directly from unwinding rolls or supply rolls 64,66. While a pair of supply rolls 64,66 is shown, to form a two-ply web, 62, it is to be understood that multiple supply rolls may be provided for any desired to provide a single ply web or a multi-ply web in which the plies have been previously joined.
  • the rolls 50,54 may be utilized as embossing and feeding rolls, drawing the web or webs from a supply, embossing the web as it passes through the nip (68) and feeding the web toward downstream processing stations, for example a perforating station represented by perforating roll 70 shown in Figure 3.
  • perforating roll 70 shown in Figure 3.
  • a first pair of rolls 80,82 may be provided with protuberances 83 on the rigid or steel roll, and corresponding recesses 81 on the resilient roll cooperating as the rolls are in rolling contact or engagement.
  • the hydraulic system may also be provided for retracting rolls, and for urging the rolls together, as represented by cylinders 84,86.
  • an additional pair of embossing rolls may be provided, with a roll 88 having a rigid outer surface, such as steel, with a plurality of protuberances 90 thereon.
  • the roll 88 will be placed in rolling contact with a roll 92 having a resilient outer surface, with recesses provided for receiving the protuberances 90.
  • Hydraulic means 96,98 may also be provided.
  • the embossed pattern defined by the protuberances 90 may be the same or different from that of the protuberances 83. Where the embossed pattern is the same, the repeated embossing operation of the second pair of rolls improves the definition of the embossed pattern, as well as improving the softening by virtue of additional working of the fibrous web. Where the pattern is different, additional or more intricate patterns may be formed to supplement the embossed patterns formed by the first pair of rolls (80,82), with softening enhanced by virtue of the additional working of the fibrous web by passing the web through a pair of rubber to steel embossing nips.
  • the web 100 will pass through the first nip 102 formed by the first pair of rubber to steel mated rolls 80,82, and then to the second nip 104 formed by the second pair of rubber to steel mated embossing rolls, 88,92.
  • the web will then be fed to downstream processing stations.
  • the rolls can be utilized as feed rolls to draw the web directly from a supply, and the need for a large separate embossing station having huge rolls and heavy duty frames and hydraulic systems is eliminated. It is to be understood however that, if desired, feed rolls may be utilized between the supply rolls and the embossing rolls in accordance with the present invention.
  • FIG. 5 Another rubber to steel embossing arrangement, as shown in Figure 5, provides a pair of nips for two embossing operations to be performed on a web 110, while only a single rigid roll 112 is utilized.
  • a pair of rolls 114,116 is provided having resilient outer surfaces, with recessed portions 115,117 provided corresponding to the embossed pattern to receive protuberances 113 of the rigid roll.
  • the resilient rolls will be urged toward the rigid roll by suitable hydraulic means 120,122, with the resilient rolls forming nips with the rigid roll at substantially diametrically opposite locations on the rigid roll 112.
  • the arrangement of Figure 5 is particularly advantageous since the two step embossing is provided, while less rolls and less hydraulic force applicators are required, for example as compared to the arrangement of Figure 4.
  • the web maintained against the steel roll (as shown at 112a) as it passes from the first nip 123 to the second nip 124, as shown at 112a, the registration of the embossed pattern provided at the first nip 123 is maintained as the web passes through the second nip 124.
  • a small amount of slack may be provided as represented by the broken line shown at 125, such that the web is not in engagement with the roll 112 as it passes from the first nip 123 to the second nip 124.
  • the diametrically opposed relationship of the resilient rolls on the rigid roll can further be advantageous, since the forces of the hydraulic systems are directed in opposite directions, and the deflection at each of the nips will be reduced or counteracted.
  • Figure 6 representatively shows forming a female resilient roll utilizing a laser.
  • a roll 130 is provided having a resilient outer surface upon which the female recesses are to be formed.
  • a laser 132 is provided having an appropriate control system 134 for forming the embossed pattern along the length and about the periphery of the roll.
  • the laser directs energy in the form of an intense light beam which burns away selected portions of the resilient roll 130 to form the recesses for receiving protuberances of a rigid male embossing roll for forming the embossed pattern.
  • the laser system can be similar to that utilized in forming patterns in press plates for printing operations.
  • the laser will burn away portions of the rubber at predetermined areas along the length of the roll, with the roll periodically rotated (arrow B) to form the recessed portions about the periphery of the roll.
  • a motor 136 is provided for periodically rotating the roll, with the motor connected to the control 134, such that the roll positioning and recess forming by the laser are coordinated.
  • the control 134 will selectively actuate the roll drive, or at least will receive a signal from the roll drive to indicate positioning of the roll such that the desired recess pattern can be formed about the roll periphery.
  • a laser can be utilized for forming recesses in a resilient embossing roll, for example, a roll having an outer rubber surface.
  • the resilient roll can then be placed in contact with a rigid embossing roll having a plurality of protuberances which are received by the recessed portions of the resilient roll.
  • the rolls may be formed of a much smaller diameter, thereby tremendously decreasing the capital costs associated with the embossing equipment.
  • deflection is not a problem, the more consistent highly defined pattern may be provided across the width of the fibrous web being embossed. Utilizing mated rubber to steel embossing, separate feeding rolls and a large embossing station are not necessary since the rolls may be utilized as feeding and embossing rolls, with the mated rubber to steel rolls drawing the web from supply rolls, and feeding the web to downstream processing stations.
