Definitions

  • the invention relates to an spreader roller for spreading running flexible web material, which the characteristics of the generic term of claim 1.
  • Spreader rolls are used to feed web material which not sufficiently smooth or even and especially with longitudinal folds tends to spread out smoothly before it is processed, cut, rolled up, stored or used in any other way.
  • thinner Foils, but also paper webs, textile webs and the like must be spread out smoothly before processing, storage or the like, since folds, waves, distortions and the like remaining in the material not only convey an unattractive appearance, but also to the Mark surfaces of other track sections with which they do not spread or insufficiently spread track sections for example, come into contact when rolling up.
  • the invention has for its object to a spreader roll create which press value can be produced and nevertheless one shows improved spreading effect, especially when very to spread thin and light flexible web material and is to be spread.
  • the spreader roller designed according to the invention effectively prevents wrinkles or other distortions the incoming material web, which is always in the longitudinal direction of the Extend web of material into the surface of the Spreading document of the incisions located on the spreader roller can put or work in, because these cuts run not in the same direction as the running direction of the material web and hence the wrinkles or warps. Therefore, it is uniform and perfect spreading of the material web guaranteed.
  • Spreader roller Since the spreading effect of the roller depends to a large extent on like the elastic formed by the oblique incisions Sections of the spreader covering under the contact pressure of the over the Dodge roller running web material is in the invention
  • Spreader roller also improves spreading because it does so avoiding sections in the same radial planes of the roller lie, but because of the helical formation of the incisions shift constantly when the roller rotates and thereby the Location of the contact points between the material web to be spread and the spreader roller changes constantly in the area of the incisions.
  • Material web is recorded over the entire width and in Stretching direction or spreading direction moves as far as possible and necessary is.
  • the spreader roller (1) shown in its entirety in FIGS. 1 and 2 has an inelastic to rigid cylindrical roller body (2) whose front ends serve as journal journals (3 and 4) are arranged.
  • roller body (2) On the outer circumference of the roller body (2) is a jacket-shaped covering (5) made of elastomeric material, which rotates with the Roller body (2) is connected and for spreading one over the Spreader roller (1) running material web (6) and / or for cutting of cut apart in the longitudinal direction of the material web individual ribbon-like or strip-shaped webs is used.
  • a jacket-shaped covering (5) made of elastomeric material, which rotates with the Roller body (2) is connected and for spreading one over the Spreader roller (1) running material web (6) and / or for cutting of cut apart in the longitudinal direction of the material web individual ribbon-like or strip-shaped webs is used.
  • each Incision (8 or 9) from the area of the radial center line (7) up to or at least close to the corresponding end of the Spreader roller (1) extends.
  • each is obliquely undercut helical incision (8 or 9) inclined from the inside to the outside, whereby the inner end (10) closer to the central plane (7) of the roller lies as the outer open end (11).
  • This will distinguish between the individual turns or passages of the respective undercut Incisions (8 and 9) formed a helical web (12) leading to corresponding end of the spreader roller (1) under the system pressure avoid the material web (6) running over the spreader roller can, causing the spreading or separating effect of Spreader roller (1) is achieved.
  • Fig. 3 the incision is partly straight and partly shown with curved flanks or walls to show that both embodiments of the incisions are conceivable.
  • the cuts of a spreader roller have a practical design but only the curved shape throughout.
  • Fig. 3 is the helical incision (9) of the covering (5) shown so that the individual turns of the same are inclined, but - straight or curved - parallel next to each other - in Axial direction of the spreader roller (1) seen - are arranged. It is but also possible to choose the inclination of the incisions (8 and 9) so that the individual gears or turns overlap one another, either by choosing a different angle of inclination of the concerned Incisions (8 and 9) and / or the choice of width between the Incisions remain standing helical webs (12).
  • the covering (5) contains one in the area of the radial central plane (7) circumferential radial incision (18), which is practically none Shows spreading effect, but behaves neutrally.
  • the spreader roller (1) shown in the drawing causes web material (6) under longitudinal tension or tension, which runs over the spreader roller (1), as shown in Fig. 1, in Spread the area of the roller and thus smoothed to in incoming strip material (6) located in the longitudinal direction Waves (17) or other densifications, bulges, faults and Eliminate the like before the web material (6) another Processing or use fed or rolled up for storage or otherwise it is filed.
  • the spreader roller is also suitable, material cut into strips in the longitudinal direction spread out or separate its individual strips from each other.
  • the spreader roller according to the invention does not need a drive to be connected in order to develop their spreading effect. Much more it can also be freely rotated or even braked.
  • each helical incision 8 or 9 is - 3 - semicircularly curved. This results in a particularly uniform bending back of the helical webs 12 and thus a particularly good one Spreading effect achieved.
  • the annular incision 18 shown in Fig. 2 can also as wider indentation can be formed, which in the central region of the Spreader roller in which there is no helical incision 8 or 9 is one that affects the long distance or completely Preventing the wide web of material 6 from spreading directly prevented.
  • This screwing can, for example, the outer diameter the spreader roller in their area by 0.6 mm to reduce the to show desired effectiveness.
  • the width of those in the middle of the spreader roller Zone in which there are no helical incisions 8 or 9 and those to avoid poor spreading of them running material webs 6 preferably a reduced Should have diameter, can according to another characteristic of Invention can be reduced in that the inner ends 19 and 20 of the respective helical incisions 8 and 9 by 180 ° are offset against each other and not - as shown in Fig. 2 - lie side by side.
  • the ends 19 and 20 of the helical cuts 8 and 9 can already in the area of the outer diameter of the Spreader roller reducing indentation or incision 18 are located.
