Definitions

  • the invention relates to a tensioning machine with a horizontal drying zone for the continuous treatment of a web held between chain links consisting of chain links, the two longitudinal edges of which can be detachably fastened to the chain links in a coupling zone, each of the chain links having pivot pins with a neighboring chain link, the connecting pins of which Axes are essentially perpendicular to the plane of the web, with the tension chains - horizontal in the drying zone - being assigned guide rails with load-bearing roller or slideways for the chains.
  • the tension chains are endless. Seen in the direction of web transport, they are deflected in front of the coupling zone (single-needle field) and after a decoupling zone (needle-out field) by shafts, the axes of which are perpendicular to the adjacent web surface.
  • the coupling zone single-needle field
  • a decoupling zone needle-out field
  • the present stretching machine should be suitable for drying a pretreated web, for example coated on both sides in a pretreatment zone, or a web coated and / or dyed in the pretreatment zone and consisting of glass fibers or containing glass fibers. Coated material webs may only then be touched - e.g. on rollers
  • tenter frame dryers with chain links consisting of chain links for a web stretched out between the chain tensioners, e.g. textile fabric.
  • the web is held at its two longitudinal edges in needles or clips through a drying and optionally fixing zone.
  • the web edges are needled or clipped in a pin-up or clipping zone, or coupling zone for short.
  • An example of such a tenter frame is described in EP 00 73 915 B1.
  • the tensioning chains run in or on guide rails, which take up the weight of the tensioning chain and the supplied web on the one hand and the transverse tension exerted on the web (transversely to the web transport direction) on the other.
  • the guide rails are essentially horizontal. They have load-bearing roller or slideways that bear the weight of the chain (possibly including the web). Each guide rail also has a tensioning roller or slideway that absorbs the transverse tension exerted on the web.
  • An example of a tension chain equipped with corresponding sliding elements is described in DE 33 33 938 A1.
  • the web is taken up in the tension chains described, stretched to a certain width and fed to a vertical dryer. Since dryers cannot be built to any height due to the fact that the height of the respective factory hall is usually too low, it has been proposed that the tension chains with the web of material already incorporated therein, coated on both sides, through a 90 ° deflection zone of the tension chains on - preferably - circular - curved or curved guide rails ( from vertical to horizontal) with a smooth transition to a horizontal position of a drying zone.
  • roller chains in which the driving forces are relatively small due to the low friction even with large goods transverse forces.
  • roller chains can only be deflected horizontally.
  • the invention is based on the object of designing a so-called “horizontally deflected” tensioning frame chain in such a way that it can be deflected without bearing damage — on the connecting bolts — even when the bolt axes are tilted spatially.
  • the solution according to the invention for the tensioning machine described at the outset is that the connecting bolts, with a 90 ° deflection zone of the guide rails switched on between the vertical coating unit and the horizontal drying zone, are convex for a vertical tilt angle between the chain links corresponding to the curvature of the deflection zone.
  • the pin bearing is formed in the chain in accordance with the crowning of the pin shape.
  • a crown for a tilting of adjacent connecting bolts of the order of magnitude is achieved.
  • Figure 1 shows a cross section through a device according to the invention with a horizontal plane clamping frame and upstream vertical coating unit.
  • Fig. 2 shows an enlarged section parallel to the drawing area of Fig. 1 by a tension chain with crowned pin.
  • FIG. 1 shows an exemplary embodiment of a device with a coating unit 1 for coating a web 2 on both sides with subsequent drying of the coating in a stenter dryer 3.
  • the web 2 is fed from roll 4 via web tension controller 5 into the coating unit.
  • the material web is coated on both sides and drawn essentially vertically upwards through a single-needle field 6 (coupling zone).
  • the web edges are attached to tension chains 7, which run in guideways 8.
  • the chain links of the tensioning chains can be equipped with the usual needle bars or those previously used as standard.
  • the single-needle field 6 has a vertical length of approximately 2 m following the coating unit 1.
  • a quarter-circular deflection zone 9 adjoins the single-needle field 6, the radius of curvature R of which in the exemplary embodiment should be approximately 3 m.
  • the deflection zone can be horizontal at its upper end 10 immediately or after passing through, e.g. 2 m long, inspection zone 11 into the dry fields 12, 13 etc.
  • a conventional stenter dryer 3 open.
  • the latter can usually have one, two, three or more such drying fields 12, 13.
  • the drying fields are followed by a run-out zone 14, for example with a needling field 15 and web tension controller 16 and take-up roll 17.
  • the floor 18 of the tenter dryer 3 is approximately 5.5 m above the factory floor 19 (on which the coating unit 1 is also located).
  • the maximum height (here the fans 20) of the system is approximately 9 m. Factory halls of this height are common.
  • the web 2 can be supported in the region of the deflection zone 9 by an air cushion 21.
  • FIG. 2 shows an enlarged drawing of the tensioning frame chain 7 according to FIG. 1.
  • the tension chain 7 consists of chain links 23 with so-called inner links 24 and chain links 25 with so-called outer links 26.
  • the chain links 23 and 25 are held together by the connecting bolts 22. Accordingly, the connecting bolts 22 absorb the longitudinal chain forces.
  • Clip or needle bars are attached to the connecting bolts 22 or to the brackets 24 and 26 for laterally holding a web of material to be processed.
  • the tension chain 7 runs in operation in a transport direction 27 and is tensioned in this direction. At the same time, horizontal transverse forces acting on the chain 7 from the web (not shown) to be processed are intercepted with the help of rollers 28 which run on correspondingly shaped parts of the guide rails 8. The castors absorb the lateral shear forces.
  • rollers 28 are supported according to FIG. 2 via bushings 29 on steel bushes 30, which coaxially comprise the bolts 22.
  • the connecting bolt 22 is mounted in the respective steel bushing 30 with the aid of a plastic bushing 31 in a lubrication-free manner.
  • the bolt 22 is therefore crowned at least in the area of its bearing parts 31, 32.
  • the bearing parts namely the plastic bushing 31 and the steel bushing 30, are adapted in their shape to the crowning of the bolt. If the crowning of the pin should only be sufficient for tilting the pin axis 32 by approximately 2 °, the remaining parts of the chain 7, in particular the rollers 28 with the associated slide bearing 29, can in principle remain unchanged.

Abstract

L'invention concerne une machine d'étirage dotée d'une zone de séchage horizontale et d'une zone de prétraitement verticale pour une nappe de tissus déployée entre des chaînes d'étirage. Lesdites chaînes d'étirage sont déplacées pour passer d'une position verticale à une position horizontale dans une zone de déviation. L'objectif de l'invention est de réaliser une chaîne d'étirage à déviation autour d'axes perpendiculaires à la surface des nappes de tissus, de manière à guider la chaîne, lors de l'inclinaison des goupilles de fixation, à travers la zone de déviation sans endommager les paliers des goupilles. A cet effet lesdites goupilles de fixation se présentent sous la forme d'éléments bombés. Les supports des goupilles de fixation sont formés de manière à correspondre à la forme bombée desdites goupilles de fixation.
