Description

The invention relates to a method for continuous Drying and shrinking textile mesh or Woven goods, whereby the wet goods to be treated within one between at least two endless, air-permeable guide bands Flow channel for drying on both sides through at least one opposite to each other, against each other to and offset hot air nozzles facing each other formed drying station leads, the one to goods to be treated with lead on an endless, in the blowing direction at a distance through the flow channel forward moving tenter attached and so laterally fixed by the drying station leads, so that the goods to be treated in the respective Blow area of a single hot air nozzle temporarily on the guide belt facing away from the latter to the system comes, as well as a device for performing this Procedure.

A method of the type mentioned is from DE-A-29 27 974 (preamble of independent claims 1 and 9) is known. With this procedure, that is Textile to be treated in both longitudinal and in Lateral and loose or cam-like or hill-shaped passed through the drying station. According to the prior art has not been recognized to achieve the lower and / or that of the shrink effect upper guide belt faster than the tenter chain have to be moved forward. Another, out EP-A-148 113 previously known method is the one to be treated Textile goods also in both longitudinal and transversely loosely within one between two endlessly running guide bands formed guide channel in wave form through two drying stations passed through. With these two previously known methods is the width of the goods treated in this way the loose management of the same during the Treatment process uneven.

The object of the present invention is to create a process in which with simultaneous improvement the residual shrinkage values an improved dimensional accuracy the treated web is reached.

According to the invention, this object is achieved according to claim 1.

Advantageous further developments of the invention Procedures are the subject of claims 2 to 8.

The invention further relates to a device according to claim 9 for performing the inventive Procedure.

Advantageous further developments of the invention Device are the subject of claims 11 to 14.

The invention is explained below with reference to the drawing, for example. It shows

  • 1 shows a longitudinal section through an example embodiment of a device according to the invention.
  • Figure 2 on a larger scale a section along the line II-II in perspective.
  • 3 shows a perspective view on a larger scale of the web stretching device A in FIG. 1;
  • 4 schematically shows a top view of the upper runs of a lower guide belt unit of a second exemplary embodiment of a device according to the invention;
  • 5 schematically shows a perspective view of a web support and transport unit that supports the uniform narrowing of the web;
  • 6 schematically shows a side view of a further exemplary embodiment of the guide belt units of a device according to the invention; and
  • Fig. 7 on a larger scale a cross section through a special embodiment of the hot air nozzles.
  • As can be seen from FIG. 1, the one to be treated is carried out moist web 1 within a between two endless, air-permeable guide bands 2 and 3 formed through channel 4 to both sides Loading and drying by three successive, drying stations designed in a known manner 5,6 and 7.

    These drying stations 5, 6 and 7 are known Way with laterally spaced, against the Flow channel 4 to directed hot air slot nozzles 8 or 9 provided, which are transverse to the direction of transport D of the tissue web 1 to be treated via the extend the entire width of the two guide bands 2 and 3.

    The exiting through the hot air slot nozzles 8 and 9 Hot air is applied to the patient to be treated Goods web 1 via the air filter 10 and the Heat exchanger 11 sucked in by the fans 12 and reheated the respective hot air nozzles 8 and 9 fed.

    As can be seen in particular from FIGS. 1, 2 and 3, becomes the wet web to be treated 1 to achieve an as even as possible stretch over their entire width of a width stretching device A first and then an endless, blowing in the direction of Distance moved forward through the flow channel 4 Clamping frame 13 fed and with lead in place B attached to the tenter frame 13 by needling.

    The width expansion device A, as can be seen from FIG. 3, in a known manner with two revolving, between them grooved rollers 14 forming an expansion gap and 15 provided. After this width stretching device A is the web 1 over several spreading rollers Needling unit B supplied.

    To achieve a wave motion in the Pass-through channel 4 moving web 1 to be treated are the upper hot air slot nozzles 9 in the transport direction D seen this web 1 compared to the lower Hot air slot nozzles 8 arranged offset.

    After the needles on the side are stretched so wide Material web 1 by means of the needling unit B in the stenter 13, the goods 1 from an initial width F (see Fig. 5) one viewed conically in the web support plane C. tapering to the desired treatment width H narrowing across the entire respective web width G laterally extending web support and transport unit 30, always on the side still by the endlessly circulating, also analogously to it tapered tapered tenter 13 held, and up to the inlet of the dryer 5,6,7 transferred. This way, the narrowing the web width F to that fed into the dryer 5,6,7 Treatment width H as uniform as possible Goods exit structure achieved because the goods 1 when narrowing down on the upper runs the endlessly circulating transport cables 31 rests and the latter thereby a uniform narrowing the web 1 over its entire varying width G support.

    As can be seen from Figure 2, the endless revolving Clamping frame 13 one for lateral fixation of the web 1 to be treated provided with needles 16 and 17, formed by an endless chain on the left and right-hand web holder 18 or 19 on whose orbital speed to align the The weft direction is individually controllable it is crucial that the guide belts 2.3 faster be moved forward than the medium speed of the two web supports 18 and 19.

    In the illustrated embodiment, one of the two endless chains 18 and 19 inside the flow channel 4 to prevent damage to the top Guide tape 2 through the needles 17 by one in Longitudinal direction of the guide channel 4 extending Guide and cover channel 20 out. Here are the two web brackets 18 and 19 to adjust the Tenter frame 13 to a certain web width in lateral direction E adjustable. Of course it is also possible to keep the web holder 18 inside one of 20 analog guide and cover channels between the upper and lower guide bands 2 and 3 lead through.

    The guide and cover channel 20 is vertical Direction on the upper and lower guide bands 2 and 3 supported, and in contact with the latter Passing 21 and 22 with friction reducing Material such as Teflon®, coated.

    By this lateral guidance in its transverse direction tensioned web to be treated 1 by means of an endless running through the dryer circumferential tenter frame 13, can with respect to Structure, dimensional accuracy and dimensional stability extremely uniform end product can be achieved.

    To e.g. in the case of a warped web 1, the weft direction or the stitches on a perpendicular to the longitudinal direction of the web align the straight line, and / or seen across the web width to achieve a more homogeneous end product It is to achieve compression or stretching effect, as from a figure 4 visible, possible instead of one lower and upper guide belt 3 or 2 several to provide narrower guide bands 3 ', 3 "and 3"' and their rotational speeds v1, v2 or v3 individually with the help of an opto-electronic web scanning arrangement such as from the company Mahlo, FRG, or Erhard & Leimer, FRG, is available.

    The compression or stretching of the web to be treated 1 more targeted to a specific density to be able to, it can be seen from Figure 5, too possible instead of one lower and one upper Guide belt 3 or 4 several, successive independent guide band groups 2a, 3a; 2 B, 3b and 2c, 3c and their rotational speeds v1, v2 or v3 individually in groups With the help of an opto-electronic web scanning arrangement to control.

    To the shrinkage effect in the shrink zone of the dryer too amplify, it is expedient if, as can be seen from FIG. 7, the outflow direction I of the hot air nozzles 8 and 9 in this zone against the direction of travel of the web D by an angle α in the range from 1 to 40 ° runs inclined to a vertical. The Blow strength and the angle of inclination α are such to coordinate with each other that no essential in operation Displacement of the two guide bands 2 and 3 fabric web areas lying in places. With such a design of the hot air nozzles 8 'and 9' in the shrink zone of the dryer can be opposite the conventional vertical arrangement of the hot air nozzles a significant reinforcement on impact on the respective guide belt 4 or 3 on the material web 1 to be treated achieved compressive force will.
