Definitions

  • the invention relates to a device for regulating the supply of heat in the heat treatment of running woven or knitted webs or the like.
  • the webs of material are guided around the lateral surfaces of heated rollers or cylinders via guide rollers.
  • guide rollers are attached to the lateral surfaces, through which the web is guided so that the wrap angle of the web on the rollers or cylinders is as large as possible.
  • the present invention is intended to avoid these disadvantages and, in particular, to solve the problem of being able to quickly adapt the heat supply from the roller or cylinder jackets to the web of material to different requirements.
  • the invention proposes, in a device of the type mentioned, to arrange the guide rollers arranged in front of and behind each heatable roller or cylinder so as to be pivotable in different positions around the lateral surfaces of the rollers or cylinders and to assign length compensation devices for the web to the pivotable guide rollers.
  • the guide rollers can be adjusted as a function of the measured values of a residual moisture measuring device for the material web arranged at the end of the treatment. It has proven to be advantageous to control the regulation of the wrapping of the material web on the roller or cylinders using microprocessors.
  • the control can take place in such a way that in the case of a plurality of rollers or cylinders, the wrap is only changed in one roller, if that is not yet sufficient for the following or previous roller or cylinder and so on.
  • the regulation can also be carried out in groups of two or more rollers or cylinders or in any other suitable or necessary manner. In no case is a change in the speed of the rollers or cylinders provided or necessary, which would be far too cumbersome for a quick control.
  • the microprocessor control also gives the option of a preselectable adjustment of the guide rollers and the length compensation devices required for the particular properties of the web to be treated.
  • the web 10 runs as the figure shows, on a guide roller 12 on the outer surface of a heated cylinder 11, wraps around a substantial part of its circumference and is finally removed via a further guide roller 12 from the outer surface of the cylinder. Then the web 10 is fed via a guide roller 12 to a downstream cylinder 11 and so on until all the cylinders provided for the treatment have been rotated. At the end of the treatment, a residual moisture measuring device 14 is then arranged, which gives its measured values to a microprocessor 16, by means of the controller 15 for the adjustment of the guide rollers 12 to set a smaller or larger wrap angle of the web 10 on the cylinder 11, as in FIG Drawing is indicated to be controlled.
  • the guide rollers 12 are assigned length compensation devices 13 for the web, which can be designed as simple dancer rollers or in any other suitable form known per se.
