Definitions

  • the invention relates to a device of the type corresponding to the preamble of claim 1.
  • Such devices are known from DE-PS 14 60 265 and DE 37 33 996 C2.
  • another such inflatable hose is arranged in the "opposite side surface" of the trough, opposite the inflatable hose, so that the material web runs between the hoses.
  • the web runs vertically downward below the interacting hoses and passes through a pair of squeeze rollers in which the applied treatment liquid is at least partially squeezed off.
  • the web runs vertically downward below the hoses and is then guided at some distance over a deflection roller.
  • the strong tendency to shrink is counteracted during mercerization in that the web after the application of the mercerizing liquor is held in a so-called bound web guide, in which the web is guided over a sequence of adjacent or practically adjacent guide rollers and between the guide rollers no free web path occurs.
  • the web is held on the circumference of the deflection rollers by the friction caused by the web train and is prevented from shrinking.
  • a characteristic of the generic application devices is the possibility of impregnating the web with a relatively high amount of treatment liquid in the range from 100 to 200% by weight.
  • the web of material is evenly stripped off at the hoses and leaves the application device with a load that cannot be easily reached with other application devices.
  • the loading is on both sides and is even massaged into the interior of the web by passing the slot between the tubes.
  • the invention has for its object to design a generic application device so that after leaving the gap on the hose arrangement until a free web path given a bound web guide is as short as possible.
  • the same goal is achieved by designing the countercarrier according to claim 2 with a concave underside which is adapted in radius to the circumference of the deflecting roller and through which a tip reaches into the gusset between the web running downward and the deflecting roller affected by it is formed, which is opposite the hose.
  • the deflection roller can be placed as high as possible in this way, so that the distance from the hose gap to the deflection roller is short.
  • the deflecting roller is driven (claim 3), in order thereby to be able to pull the web of material through the hose gap and at the same time be able to exert a longitudinal tensile stress which counteracts the longitudinal shrinkage of the web of material which also occurs.
  • a feature that is significant in cooperation with the high application of treatment liquid and the practically immediate transition to the bound goods guide is the subject of claim 6. Because the top rollers can be raised in the usual mercerizing roller sequence, squeezing at the transition from a deflection element can be done roller to the next avoided and the effect of the high application of treatment liquid over at least part of the subsequent treatment section in bound web guide are maintained. What is achieved with the application device and the arrangement of the deflecting roller, namely the high loading and the practically immediate transition into the bound web guide, are only really brought into play by giving the relatively large amount of treatment liquid on the web the opportunity to act on a longer dwell.
  • the bearings of the top rollers can allow a free self-adjustment of the top rollers in relation to the respectively adjacent bottom rollers.
  • the top rollers are therefore not rigid, but "loosely” supported, i.e. more managed, and can find their optimal investment position themselves.
  • At least one of the lower rollers following the deflection rollers is driven in order not only to have a bound web guide to avoid transverse shrinkage, but also a certain longitudinal expansion of the web at at least some points to be able to bring about.
  • the prerequisite for this is, of course, that the driven lower roll in question and the subsequent upper roll do not touch to form a roll gap.
  • FIG. 1 shows a side view of the application device
  • Fig. 2 shows a view along the line II-II in Fig. 1, partly in section;
  • FIG 3 shows a side view of the application device with a treatment line connected downstream.
  • a textile fabric web 1 made of cotton material is guided over a spreading roller 2 and an upper deflecting roller 3, and from there in a vertically downward section 1 ′ through a trough 4 with treatment liquid 5 to be passed.
  • the trough 4 extends at least across the width of the web 1 and has a left side surface 4 'as shown in FIG. 1 and an equally right side surface 4 "which face each other downward to form a wedge-shaped cross section in a direction of the web 1
  • the left side surface 4 ' is formed by a carrier 6, which in turn is supported on a support beam 7 in the form of a hollow profile carrier with a square cross section.
  • the carrier 6 has the cross-sectional shape shown in FIG. 1 in a vertical plane perpendicular to the web 1. 1 to the right, i.e. an inflatable hose 9, which extends horizontally across the width of the web 1 and is open towards the web 1, is inflatable, which can be filled with compressed air of a controllable pressure via an external connection 10, and is somewhat under pressure from the recess 8 1 bulges out to the right.
  • the side surface 4 ′′ of the trough 4 opposite the hose 9 is formed by the wall of a box-shaped counter-support 11, which is also located over the The width of the web extends and at least in the area 4 '''opposite the hose 9 consists of polished, corrosion-resistant steel, which has good sliding properties for the web 1 and forms a smooth, closed sliding surface for the web 1. Between the hose 9 and the area 4 ''', the hose gap 12 is formed, through which the web 1 passes.
  • Pasting the web 1 on this side of the hose gap 12 is unproblematic at the rigid and smooth lower region 4 ′′ ′′ of the side wall 4 ′′.
  • a film 18 made of thin, corrosion-resistant sheet metal is provided hen, which extends over the width of the web and is clamped between the upper region of the side wall 4 'and the baffle there by means of the screw 15.
  • the sliding film 18 extends down the side wall 4' in front of the hose 9 through the Hose gap 12 therethrough in order to sag in a free loop underneath the hose gap 12 and to be fixed there on a holder 19.
  • the hose gap 12 limits the trough 4 at the bottom.
  • end plates 13 which are tightly fastened in the manner indicated by means of screws 14 to the end faces of the opposing support and form transverse walls which extend as far as the opposite side surface 4 'of the support 6, the over the respective end face of the counter beam 11 extends.
  • This also applies to the sliding film 18, which rests on the side surface 4 'and is pressed in a sealing manner from the end face 13' of the respective end plate 13, in which a seal can be arranged (FIG. 2).
  • the inflatable tube 9 presses the web 1 against the lower region 4 ′′ ′′ of the side surface 4 ′′. As it passes through the tube gap 12, the web 1 is stripped on both sides to a relatively high moisture content determined by the pressure in the tube 9, the 100 to 200% by weight of the dry goods can be.
  • the trough 4 contains only a small amount of treatment liquid, which is continuously renewed.
  • guide plates 16 which are angled by means of screws 15 are fastened to the upper ends of the side surfaces 4 ′, 4 ′′ and form drain surfaces 16 ′ inclined towards the trough 4, on the upper edge of which the treatment liquid is applied from supply pipes 17 Outflow over the drainage surfaces 16 'is uniformized into a film which flows laminarly along the side surfaces 4', 4 "into the trough 4.
  • the material web 1 After it has passed the trough 4 and the hose gap 12, the material web 1 continues its path below the hose gap 12 vertically downward in a section 1 ′′ which, up to the run-up point 1 ′′ ′′, is arranged on the circumference of one under the counter support 11 Deflecting roller 20. The web 1 then wraps around the deflecting roller 20 in its lower region and is located on it in a so-called bound guide, ie it is held onto it by the friction of the system and cannot shrink freely. Section 1 "is an unavoidable one free web section that should be designed as short as possible.
  • the underside 21 of the counter support 11 is concave in accordance with the circumference of the deflecting roller 20 and is arranged closely above this circumference.
  • the deflecting roller 20 can be set higher in order to bring the run-up point 1 ′′ 'closer to the hose gap 12 as far as possible.
  • the counter beam 11 forms in its cross section a tip 22 which extends down into the gusset between the section 1 "of the web and the circumference of the deflecting roller 20 and there at the lower end of the side wall 4" the area 4 '''of the sliding System of the goods web 1 and forms the hose gap 12.
  • the treatment section 200 consists of a sequence of deflecting rollers. These include mutually parallel lower rollers 20, 30, 40 arranged in a horizontal plane, of which the lower roller 20 is formed by the deflecting roller 20 of FIGS. 1 and 2 and in the exemplary embodiment the lower rollers 20 and 40 are driven.
  • the lower rollers 20, 30, 40 have the same diameter and leave equal distances from one another which are smaller than the diameter. In the gaps between the lower rolls 20, 30 and 30.40, non-driven upper rolls 25, 35 of this diameter are also provided.
  • the material web is guided in a meandering shape over the sequence of the deflecting rollers 20, 25, 30, 35, 40, ... and does not experience any free material path in the treatment section 200.
  • the upper rollers 25, 35 can rest on the lower rollers 20, 30, 40 at the positions 26, 36, 46, 56, whereby they are mounted "loosely", ie they can find their support position themselves.
  • the positions 26, 36, 46, 56 form roll gaps in which the web 1 experiences a line force. This can be undesirable in certain cases, for example if the relatively large amount of treatment liquid applied in the application device 100 is not to be squeezed off immediately.
