Definitions

  • ABSTRACT In a broad-drawing roll for moving webs of paper or the like, including a plurality of individual roll sections defining an arcuate curve to spread the web, the improvement which comprises a plurality of supporting bearings provided between the individual roll sections, said bearings being adjustable selectively and independently of one another and thereby determining the degree of curvature defined by said roll sections.
  • Each roll section is mounted in freely rotatable fashion on its own shaft of substantially the same length as the section. Bearings, comprising two halves meeting along a line diametrically of the shaft, occupy substantially the full small space between adjacent roll sections.
  • the invention relates to a broad-drawing roll for moving webs of paper, plastic or the like, which consists of a plurality of individual sections.
  • Broad-drawing rolls are used mostly where materials in web form, such as paper, foils, fabrics or the like, are being fabricated. They serve for the prevention of wrinkles in the webs such as might be caused by differences in tension in the plane of the web. These differences manifest themselves in the form of slack edges or sagging areas in the tensed web.
  • Broad-drawing rolls of the prior art consist generally of a flexible shaft on which a plurality of individual roller sections are mounted, these sections being covered by a rubber or plastic jacket extending over the entire length.
  • the degree of curvature is selected and adjusted on the basis of the working width of the paper web and the quality of the paper.
  • the curvature runs symmetrically from the center of the roll towards the two shaft bearings.
  • the disadvantage is that if the edge of the web is looser on one side than it is on the other, only one side of the web is stretched while the other side still tends to wrinkle. If the web edges are loose on oneside there is the danger of excessive straining of the area of the web that does not need equalization.
  • the invention is addressed to the problem of eliminating the above-described disadvantages and creating a free-spinning broad-drawing roll which will be adjustable locally in any area of the paper web when slack edges or sagging areas occur.
  • This problem is solved in accordance with the invention by providing supporting bearings between the individual sections of the roll, these bearings being selectively adjustable independently of one another and determining the degree of curvature.
  • the system at the same time is such that the individual roll sections are mounted so as to revolve freely independently of one another, each free-spinning section of the roll being mounted on a shaft corresponding substantially to the length of the section and the individual shafts being positively interengaged with one another.
  • the supporting bearings may be disposed in the area of contact of two adjacent shafts bearing the roll sections, the width of the supporting bearing corresponding substantially to the interstice between the two roll sections.
  • the supporting bearings consist of two parts, the seam between these parts running crosswise of the center of the shaft and intersecting it.
  • the advantages achieved by the invention especially reside in that the broad-drawing roll is variable along any part of its curvature, so that slack web edges or sagging areas may be eliminated in certain circumscribed portions of the width of the paper web by varying the curvature of the broad-drawing roll only in this portion.
  • a further advantage is that, owing to the easy replaceability of the roll sections, the stocking of bulky onepiece rolls is eliminated.
  • FIG. 1 is an overall view of the broad-drawing roll
  • FIG. 2 is a cross section taken along line 22 of FIG.
  • FIG. 3 is an enlarged view, partially in cross section, of a single roll section as taken along line 3-3 of FIG.
  • FIG. 4 is a cross section taken along line 44 of FIG. 3;
  • FIG. 5 is a cross section taken along line 55 of FIG. 3.
  • the broad-drawing roll 1 is arcuately disposed on a crossbeam 3 pivotally mounted by means of the shafts 2. It consists of individual roll sections 4 which are mounted in a freely rotatable manner on shafts 5. The individual roll sections 4 are mounted on the crossbeam 3 by means of divided supporting bearings 6 and adjusting bolts 7. The adjusting bolts 7 are each rotatably disposed in a bar'8 of the supporting bearing 6. The two supporting bearing halves 6to and 6" are joined together by the bar 9 and the screws 10.
  • the bar 9 can be removed by unfastening the screws 10, and the bearing half 6" may thus be taken out.
  • the individual roll sections 4 are spaced apart only a small distance which is determined by the width of the supporting bearings 6. This assures a uniform, non-marking contact between the paper web 14 and the broaddrawing roll 1.
  • the shafts 5 are constructed in such manner that each coupling portion 11 is positively engaged with the coupling portion of the adjacent shaft.
  • the supporting bearing 6 is provided with recesses 12 for receiving the coupling portions 11.
  • the manner of operation of the broad-drawing roll is as follows. Starting from a paper roll processing machine, which is not shown, such as a rewinding machine or slitting machine in which broad-drawing rolls are required, the broad-drawing roll 1 is pivoted to the paper web 14 by means of a linkage 13 which engages the crossbeam 3. In this manner a general smoothing of the paper web takes place, such as is known in the broaddrawing rolls of the prior art. Upon the occurrence of web edges loose on one side or individual sagging areas in the outspread paper web, which cannot be eliminated by the prevailing curvature, the broad-drawing roll 1 is locally adjusted in the direction of the web.
  • the broad-drawing roll 1 is provided with a plurality of mechanically adjustable supporting bearings. It is also possible, however, for the purpose of achieving a more rapid adjustment of the supporting bearings, to equip the broad-drawing roll or supporting bearings with hydraulic or electrical means (not shown) so as to be able to automate the compensatory movements of the broad-drawing roll .in conjunction with an optical wrinkle detecting system (not shown).
  • a broad-drawing roll for moving webs of paper or the like, including a plurality of individual roll sections defining an arcuate curve to spread the web, the improvement which comprises a plurality of supporting bearings provided between the individual roll sections, said bearings being adjustable selectively and independently of one another and thereby determining the degree of curvature defined by said roll sections, and a shaft for each of said roll sections and each of substantially the same length as its respective roll section and having its roll section mounted freely rotatable thereon, the shafts being joined together in form-fitting manner.
  • each supporting bearing comprises two parts meeting along a separating seam running crosswise of the center of its shaft and intersecting it.
