Definitions

  • ABSTRACT This invention relates to a roll system for guiding a web of material, including a three-high roll arrangement of which the takeup or delivery roll assembly includes shaft means with two disc means of the same diameter thereon, which disc means are separated by a distance greater than the width of the path of the web and in operation co-operate with the roll of the other of the two assemblies to support the intermediate roll.
  • FIG. 1 is an elevational cross section of a three-high roll assembly of the prior art
  • FIG. 2 is an elevational cross section of a three-high roll assembly of the present invention
  • FIG. 3 is a perspective view of the assembly of FIG. 2 with a heating or cooling attachment
  • FIG. 4 is an elevational cross section of the-assembly of FIG. 2 with a disc covering
  • FIG. 5 is an elevation of the simplest form of roll assembly with discs
  • FIG. 6 is a similar view showing a roll between the discs.
  • FIG. 7 is a similar view showing a roll between and integral with the discs.
  • the first group is constituted by known systems comprising a plurality of rolls disposed in spaced relationship to each other. In these'arrangements, the rolls are usually disposed in different planes. In order to achieve the required progressive change in tension applied to the web, in many cases all the rolls of the system are driven differentially.
  • the disadvantage of this roll arrangement is that on the one hand a large number of rolls have to be used, particularly when fairly large differences in tension in the web have to be achieved so that a structure of considerable size is necessary, while on the other hand, the necessary differential drive for the individual rolls and the synchronizing of the rolls with each other can be achieved only by complicated and expensive means. If the drive of only one roll is incorrectly adjusted, or alters while the machine is running, the machine conditions of the entire installation are adversely affected so that a time-consuming readjustment is necessary.
  • Roll arrangements which consist of a two-high system.
  • a roll usually rubbercoated
  • a driven roll so that a nip is formed between them.
  • an arrangement of this kind is particularly simple in construction and can provide relatively large differences in web tension
  • such a roll system has the considerable disadvantage, particularly when the rolls are of small diameter, that the nip pressure cannot be adjusted with sufficient accuracy.
  • a very small lack of precision in the adjustment of the nip pressure manifests itself in a adverse manner, e.g., in the form of off-center pull and/or creasing of the web of material. This renders the manufactured or processed webs of material unusable or alters their physical properties to an undesirable extent, or the webs cannot for example be wound with their edges neatly arranged, so that further uneconomical edge-trimming operations have to be carried out.
  • the present invention provides 'a roll system for guiding a web of material, the system including a three-high roll arrangement (FIGS. 2, 3 and 4) of which the takeup or delivery roll assembly includes a shaft 4 with two discs 5 and 6 of the same diameter thereon, which discs are separated by a distance greater than the width of the path of the web W and in operation co-operate with the roll 3, on shaft 11', of the other of the two assemblies mentioned (1, on shaft 11, and 3) to support the intermediate roll 3.
  • a three-high roll arrangement FIGS. 2, 3 and 4
  • the takeup or delivery roll assembly includes a shaft 4 with two discs 5 and 6 of the same diameter thereon, which discs are separated by a distance greater than the width of the path of the web W and in operation co-operate with the roll 3, on shaft 11', of the other of the two assemblies mentioned (1, on shaft 11, and 3) to support the intermediate roll 3.
  • the discs 5 and 6 are adapted to be axially displaceable on the shaft. This enables the corresponding roll assembly to be adjusted to suit the particular widths of the other rolls and/or the width of the web to be guided. After positioning the discs 5 and 6, they are held in position by known means such as screw-down stops or the like.
  • a roll is fitted between the discs 5 and 6, the diameter of this roll however being smaller by any desirable amount than the diameter of the discs 5 and 6.
  • the diameter of the roll 7 is preferably such that when the web W moves through the system, although there is contact between it and the roll, no nipping takes place.
  • a roll between and integral with the discs.
  • This arrangement can be regarded as being equivalent to a roll, a central portion of which, corresponding to the width of the web, has been reduced in diameter, for example by turning in a lathe, as compared with two portions at the end-faces.
  • this assembly is preferably provided with attachments 12 and 12" for supplying a heating or cooling medium.
  • tempering operations for example cooling, heating operations in the drying or stretching of the web material, and similar processing steps.
  • An arrangement is preferred in which there is contact between the web and the roll since this ensures particularly good heat-transfer.
  • the two other rolls of the three-high arrangement also may be equipped with attachments of this kind so that tempering can be carried out on a differential basis.
  • the rolls and/or the shaft and/or the discs are preferably made of steel, in particular stainless steel. For certain applications however, they may be made of other materials such as plastic materials.
  • the roll system of the invention may be duplicated several times in a single installation, and different arrangements, e.g., in the form of cooling or heating stations, may be used.
  • the roll system of the invention is inherently suited for the guiding of webs of material generally, but it has proved particularly successful in the guiding of very wide webs, of a width of approximately 3 m to m and more, and of very thin webs having a thickness in the region of um and less. More especially, the new arrangement enables extremely thin films, as made at present in polyesters for example, and having a thickness in the range of about 2 to 20 pm, to be guided in a satisfactory manner without the'webs of material being damaged as they have been when the existing machines have been used.
  • FIGS. 5, 6 and 7, 4 is a shaft and 5 and 6 are discs thereon as described above, this assembly being the take-up or delivery roll assembly of a threehigh system.
  • a roll 7 is disposed between the discs 5 and 6, the diameter of the roll 7 being less than that of the discs.
  • the discs 5 and 6 are mounted on bearings 8 and 9, respectively.
  • a roll system for guiding a web of material including a three-high roll arrangement of which the take-up or delivery roll assembly includes shaft means with two disc means of the same diameter thereon, which disc means are separated by a distance greater than they width of the path of the web and in operation cooperate with the roll of the other of the two assemblies to support the intermediate roll.
