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 to be coupled to a neighboring chain link, and wherein the tensioning chains - horizontally in the drying zone - are assigned guide rails with supporting slideways for sliding blocks of the chain links.
- the tension chains are endless. They are deflected - seen in the web transport direction or chain running direction - in front of the coupling zone (single needle field) and after a decoupling zone (needle field), the axes of which are perpendicular or parallel to the adjacent goods area and the goods transport direction. In the case of conventional plane clamping frames, this is referred to as a horizontal or vertical chain deflection, that is to say a deflection of the chain in a plane parallel or perpendicular to the plane of the web.
- tenter frame dryers with tension chains consisting of chain links for a fabric web spread out between the tension chains, for example a textile fabric web.
- 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 on in a pin-on or clipping zone, in short Coupling zone.
- 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 carried web on the one hand and the transverse tension exerted on the web (on the other hand, transverse to the web transport direction).
- the guide rails are essentially horizontal. They have load-bearing slideways (slide slides) for sliding blocks of the chain links, which support the weight of the chain (including the material path if necessary).
- 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 blocks or sliding elements is described in DE 33 33 938 A1.
- the sliding blocks themselves conventionally have a flat sliding surface, which is moved relative to the respective, also flat supporting slide.
- 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 webs of goods may generally only be touched then, e.g. deflected on rollers - when the coating has dried.
- Glass fibers often keep colors worse than the surface of rollers usually used in textile machines, so that the latter should only touch the surface of the glass fiber webs when the applied substance has dried.
- the web is taken up in the tension chains described, stretched to a certain width and fed to a vertical dryer. Since it is not possible to build dryers of any height due to the fact that the height of the respective factory hall is too low, it has been proposed that the tension chains with the web of material already incorporated in it and coated on both sides through a quarter-circular deflection zone - 90 ° deflection zone - of the tension chains on curved or curved guide rails (from vertical to horizontal) with a smooth transition to a horizontal position of a drying zone.
- the curved guide rails also have (preferably concentrically) curved support slideways.
- the guide rail which is horizontal in the horizontal drying zone and curved at the transition to the pretreatment zone, also has flat support slideways in its flat areas, and support slideways curved to the same extent in its curved areas.
- the sliding blocks of the chain links can be assigned to the supporting slideways.
- the sliding blocks have conventionally flat sliding surfaces that slide on the supporting slide tracks during operation.
- the sliding surfaces in question should be just like the (horizontal) supporting slideways so that the friction between the sliding block and the slideway takes place over a wide area, i.e. not in a line or point. If, however, the slideways in the deflection area of the guide rail are curved - that is, not flat -, the sliding blocks touch the slideways in this area in a point-like or linear manner, so that a relatively strong abrasion can result.
- the invention has for its object to form a tensioning frame chain slidably carried in the guide rails on slideways in such a way that the associated sliding blocks of the chain links touch the supporting slideways of the guide rails flatly both in their flat (horizontal) region and in their quarter-circle deflection region.
- the individual sliding block according to the invention lies flat against both the flat parts and the curved parts of the supporting slide tracks.
- the rounded region of the sliding surface assigned to the curved deflection zone is expediently located approximately in the middle of its length, viewed in the chain longitudinal direction, on the individual sliding block.
- the radius of curvature of this rounded central zone of the sliding block surface should have approximately the same value as the radius of curvature of the deflection zone of the guide rails.
- the invention preferably relates to a tensioning machine with a horizontal drying zone and a vertical pretreatment zone for a web stretched out between tension chains designed as slide chains.
- the tension chains are moved from the vertical to the horizontal position in a deflection zone.
- the sliding surfaces of the supporting sliding blocks attached to the chain are arranged in three successive zones in the transport direction, namely one flat edge zone, a curved middle zone and a second flat edge zone divided.
- FIG. 1 shows a cross section through a device according to the invention with a horizontal drying zone and an upstream vertical coating unit
- FIG. 2 shows an enlarged section parallel to the plane of the drawing of FIG. 1 through a tension chain
- Fig. 3 is a plan view (from above) of a chain link of Fig. 2;
- FIG. 4 shows a section through a tension chain according to FIG. 1 with slide bearings for receiving the tension chain
- FIG. 5 shows a section (along AA of FIG. 4) of a sliding block for receiving the chain weight of the chain according to FIGS. 2 to 4.
- 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 tenter frame dryer 3.
- the web 2 is fed from roll 4 via web tension controller 5 into the coating unit 1.
- the material web 2 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 guide rails 8.
- the chain links of the tensioning chains 7 can be equipped with conventional needle bars or those already 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 9 can be horizontal at its upper end 10 immediately or after passing through, e.g. 2 m long, inspection zone 11 open into the drying fields 12, 13 etc. of a conventional stenter dryer 3.
- 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 regulator 16 and take-up roll 17.
- the base 18 of the tenter dryer 3 is approximately 5.5 m above the factory base 19 (on which the coating unit 1 is also located).
- the greatest height (here the fans 20) of the system is approx. 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 and 3 show an enlarged view of the tension chain 7 according to FIG. 1 with rollers for absorbing the transverse forces.
- the tension chain consists of chain links 25 with so-called inner links 24 and chain links 23 with so-called outer links 26.
- the chain links 23 and 25 are held together by the connecting bolts 22.
- 3 needle strips 27 are attached to the tabs 24 Stigt.
- Each needle bar 27 has a plurality of needles 28, in which the longitudinal edge 29 (FIG. 4) of the web 2 is suspended.
- the needle bars 27 can be connected to the inner plates 24 by means of brackets 30.
- the tension chain 7 runs in operation in a transport direction 33 and is tensioned in this direction.
- horizontal transverse forces acting on the chain from the web 2 to be processed are intercepted with the aid of rollers 34 which run on correspondingly shaped roller rails 35 of the guide rails 8 (FIG. 3).
- the rollers 34 are supported according to FIG. 2 via a total of 36 plain bearings on steel bushings 37 which coaxially comprise the bolts 22.
- the connecting pin 22 is mounted in the respective steel bushing 37 with the aid of a plastic bushing 38 without lubrication.
- FIG. 4 shows a vertical section through a tension chain link transversely to the direction of transport 33.
- plain bearings are provided both for absorbing the transverse forces and for absorbing the weight forces.
- 4 contains connecting bolts 22 which are connected to lower and upper inner links 24.
- two supporting slideways 32 are particularly important, which are also to be fastened to a part of the guide rail 8.
- the slideways 32 absorb the weight forces of the chain 7.
- the support body 40 (with a chain attached) runs from the slidable surfaces 31 (see also FIG. 3). It is attached to the support body 40 which also receives the bracket 30 of the needle bar 27 in such a way that the chain 7 is slidably mounted on its way through the tensioning machine.
- the supporting slideways 32 lie horizontally like the guide rails 8 as a whole. If, however, for some reason the guide rails 8 are to be suitable for deflecting the tension chain 7 from the horizontal position into a vertical position, this deflection rich a curvature of both the guide rails 8 and the slideways 32 required.
- the sliding surface 31 according to FIG. 5 is conventionally as flat as the supporting slide 32 itself, the sliding surface 31 is divided according to the invention. 5 consists of three parts in succession in the transport direction 33, a flat region (flat first partial sliding surface 51), a cylindrical central zone (curved partial sliding surface 52) with the radius of curvature R and a second flat region (flat second partial sliding surface 53).
- the area 52 in the direction of transport 33 preferably has approximately the same length as the sum of the areas 51 plus 53.
- the flat partial sliding surfaces 51 and 53 act as contact surfaces wherever the supporting slide 32 is also flat.
