Definitions

  • the invention relates to a device for solidifying fabric strips, preferably in the case of knitwear, in particular at the entrance of a stenter, in which the strips to be solidified run on the periphery of an application roll, which is constantly supplied with a solidifying liquid.
  • Difficulties of this kind can be overcome to some extent if an application roller is used to apply the hardening liquid, which roller runs on a delivery roller which is partially immersed in a bath of the hardening liquid. In this way it is possible to have a liquid coating on the periphery of the application roll that is constant over time are maintained, but the use of the second roller makes the installation very complex, not only in terms of manufacture, but also in terms of maintenance, because part of the hardening liquid always runs off on the respective rollers and their axes or bearings and frequent and tedious cleaning makes necessary.
  • GB-A-14 62 787 also relates to a method and an apparatus for applying solidifying liquid to a textile fabric.
  • the solidifying liquid is applied directly from a trough to an application roll and transferred to the fabric web with the help of the application roll.
  • the wall of the trough is partly formed by the periphery of the application roller.
  • the level in the trough is kept constant by a screw pump and by an overflow directed into the container.
  • a pump conveys the draining liquid from the container back into the trough.
  • the invention has for its object to reduce the effort for the manufacture and maintenance of the device for solidifying web strips and at the same time to reduce the amount of air exposed to be brought directly from the solidifying liquid to the web so that the immediately for transfer to the The intended amount of liquid is consumed faster than it dries. This is associated with the further task of automatically supplementing the amount of liquid which is immediately available for consumption, because otherwise the gain could be more than compensated for by simplifying maintenance by the effort involved in refilling the trough.
  • the solution according to the invention exists for the one specified at the beginning Device for solidifying web strips, in which the hardening liquid is applied to the strips with the aid of an application roller, in that the application roller with a given immersion depth is immersed directly in the hardening liquid located in an open trough and in that a closed supply container containing the hardening liquid is provided above the liquid level a drain snorkel touching the liquid level in the trough is arranged.
  • the application roller is immersed directly in the hardening liquid, a previously common intermediate roller is saved.
  • the amount of the hardening liquid transported onto the fabric web with the one application roll can be metered precisely, because the immersion depth of the application roll in the trough should be predetermined, that is to say it should be possible to preset it as desired.
  • the liquid transport from the trough to the fabric web through the depth or distance of the periphery of the application roll can be specified exactly.
  • the prerequisite for this is that the level of liquid in the trough is kept constant despite the considerable consumption of liquid, and the level of the liquid in the trough must not be changed by refilling or pausing between two fillings. This is only possible with constant refilling to the extent of consumption.
  • the invention provides for a supply container which is completely closed on its upper side to be provided above the liquid level, but which has an outlet line which leads down into the trough and there extends to the liquid level or defines the liquid level there.
  • the drain pipe preferably starts from the bottom or from a position near the bottom of the supply container.
  • the invention therefore achieves at least three advantages at the same time: only a single application roll is required for the direct transfer of hardening liquid from a trough to the fabric web; the trough needs to contain very little liquid, because its level can be set constantly by the snorkeling process; and the mass of the solidification liquid reserve used to supply the trough is not subject to premature drying because it is located in an enclosed space.
  • the level of the liquid in the trough can be changed, namely when the mouth of the snorkel which determines the liquid level is raised or lowered.
  • the amount of the hardening liquid transferred with the help of the application roller can thus be simply carried out by adjusting the height of the snorkel.
  • the application roll is disengaged from the edge of the web of fabric.
  • the application roller which is then no longer rotating, would stick in the hardening liquid and that would Solidification liquid in the trough would become stiff and eventually harden.
  • the trough is pivoted under the specified conditions when the application device is at a standstill, preferably about an approximately horizontal axis, and is expediently cleaned, as is the application roller.
  • the supply container is also pivoted about a preferably horizontal axis in such a way that the snorkel has its opening upward.
  • the two approximately horizontal pivot axes are approximately perpendicular to one another.
  • the invention provides that the axis of rotation of the application roller rotatable in a bearing arranged at the end of a shaft is angled downward and that a bushing which is closely attached to the application roller is arranged around the bearing and rotates at a distance from the roller has a radially projecting collar. This ensures that liquid running from the periphery of the application roll in the direction of its axis always runs off on the "upper" side surface of the application roll at the intended inclination.
  • the roller is held on a shaft in a bearing on this “upper” side surface of the application roller.
  • the bushing extending around the bearing there and the collar assigned to it ensure that the liquid running off cannot get into the bearing.
  • the device according to the invention for the consolidation of fabric strips is often referred to in practice as the "edge gluing device", since the consolidation liquid is glue-like substances.
  • the edge gluing device is located below the fabric web transport or guiding means of a so-called tenter frame.
  • the device according to the invention essentially consists of an application roll 1, the periphery 2 of which comes into contact with an edge strip held in a needle chain 3, for example, or a strip of a fabric web 4.
  • the application roll is set in rotation in the direction of arrow 5 by the material web 4 moving in the same direction.
  • solidification liquid or glue 6 is transported from a trough 7 on the periphery 2 of the application roll 1 to the fabric web and applied there as a continuous strip or in the form of transverse lines if the periphery has helical teeth 8 or the like. It is essential in this device, in which the application roll 1 transports the glue 6 directly from the trough 7 to the fabric web 4, that the diving depth T or the glue line L is independent be kept constant by the consumption of glue 6. This requires a defined specification of the level 9 of the glue 6 in the trough 7.
  • a snorkel 10 reaching up to the level 9 is provided, the opening 11 of which just ends with the level 9 and which is supplied from a supply container 12 which is completely closed and arranged above the level 9 becomes.
  • the trough 12 is stored below a chain guide 13 assigned to the needle chain 3. Since the supply container 12 has no air supply other than the opening 11 of the snorkel 10, the supply glue 14 can only flow out of it via the snorkel 10 if air can pass through the opening 11 against the glue flow direction 15 through the snorkel 10. For this it is necessary that the level 9 falls slightly below the peripheral edge of the snorkel 10 in the area of the opening 11. Then when an air bubble gets into the supply container 12. A corresponding amount of glue can flow off, so that the opening 11 for the snorkel 10 is closed again.
  • the supply container 12 is generally first pivoted downward about an axis 16 in the direction of arrow 17 so that no more glue can flow out of the supply container 12. Then the trough 7 (FIG. 2) is pivoted downward about its axis 18 and is generally cleaned. In addition, the application roll 1 is brought out of engagement of the fabric web 4 by actuating a lever 19.
  • a particular advantage of the arrangement described is obtained if the application roller 1 according to FIG. 1 is rotatably held in a bearing provided at the end of an axis of rotation 20 and if the axis of rotation of the bearing is angled downward by an angle W with respect to the horizontal. This ensures that glue running from the periphery 2 of the application roll 1 always runs only on the “upper” side surface 21 of the application roll 1. If a bushing 22, which is tightly attached to the application roller and has a radially projecting collar 23 at a distance from the roller, is then arranged around the bearing, the liquid running off on the upper side surface 21 cannot penetrate into the bearing. Corresponding cleaning problems are therefore completely eliminated.
