Definitions

  • the invention relates to a relaxation dryer according to the preamble of claim 1.
  • a relaxation dryer for stress-free drying at the same time relaxing shrinking of a spread, textile fabric Woven or knitted fabric or nonwoven in an almost sinusoidal way in the relaxation channel between two air-permeable conveyor belts, namely one Carrying strap and a counter-holding belt, the fabric web together during operation is moved with the conveyor belts in the longitudinal direction of the fabric and where the fabric web running outside the relaxation channel transverse to the web longitudinal direction
  • Rows of spatially fixed blow nozzles are assigned such that the Fabric web - seen in the longitudinal direction of the web - in approximately transverse to the longitudinal direction running lines alternately against the supporting band and against the counter-holding band is blown (see for example DE 2 942 030 A1).
  • the fabric is through the conveyor belts limited and defined relaxation channel (treatment channel) that transported Transport, longitudinal and channel longitudinal directions are therefore the same.
  • the carrying tape has a transporting effect on the fabric are exercised in the context of this description - for the sake of simplicity - both Belts referred to as a conveyor belt.
  • the tapes at one two or more tier dryer also falling within the scope of the invention change their support / support function.
  • Machines of the type mentioned at the beginning are sold under the name "DynAir” by Applicant manufactured and distributed.
  • the relaxation dryer made famous in this way is used equally for woven and knitwear with a template (open) web or in tubular form.
  • the relaxation dryer is suitable also as a pre-dryer in combination with other equipment machines. He can arranged behind a foulard and with a downstream stenter, in which the fabric is stretched wide and fixed, for example, combined become.
  • a characteristic of the well-known relaxation dryer is that of a standing wave approximately sinusoidal web run between the two conveyor belts of the Relaxation channel.
  • a dryer with a horizontal web guide below the lower conveyor belt, the carrying belt, and above the upper one Belt, the counter-holding belt, nozzles arranged and - seen in the direction of the goods - alternately from below and above onto the between the conveyor belts web of material captured in the relaxation channel.
  • rows of perforated nozzles are intended to be transverse to the longitudinal direction of the goods or transport direction.
  • An upper row of nozzles is preferred between two lower rows of nozzles and vice versa, so that the Blow the web - in the longitudinal direction - alternately from its two surfaces becomes.
  • the conveyor belts are made, for example, of teflon-coated glass fiber fabric manufactured.
  • the fabric should not affect the fabric in the area of provided treatment temperatures are temperature stable and, e.g. led over smooth rollers, easy to control and to be stretched in its longitudinal direction.
  • the Relative speed or the synchronism of the conveyor belts should be adjustable his.
  • the invention is based on the object, in addition to relaxation drying Apply a tumble effect to the fabric.
  • the tumble effect is said to have no essential Conversions of the relaxation system can be generated.
  • the solution according to the invention is specified in the characterizing part of claim 1.
  • tumble stripes - currently have at least one of each of the rows of nozzles running transversely to the longitudinal direction of the web partially to shield completely. Due to the effect of the tumble strips according to the invention rhythmic air impulses in the sense of achieving one about the effect of relaxing drying increased tumble effect on the fabric. Further refinements of the invention are specified in the subclaims.
  • the tumble strips even if they are considered airtight are not absolutely impermeable to air. But you should compared to the air coming from the blow nozzles, at least noticeably larger Represent drag as the respective conveyor belt itself.
  • the indication "Partially or completely shielding" can therefore affect both the geometry and refer to the air permeability of the tumble strip. The latter can because of its shielding effect can also be called a tumble shield.
  • Tumble stripes can affect the blowing effect of the nozzle rows or the individual nozzles of each row partially or entirely, both in the longitudinal direction of the web and across it (when passing the tumble strip on the nozzle or the nozzle row) shielded become.
  • the tumble strips according to the invention can be on both sides of the relaxation channel, namely on both conveyor belts, but alternatively on only one side of the relaxation channel, i.e. on only one of the conveyor belts, i.e. on the conveyor belt or on the counter belt. With horizontal web guidance This means that the tumble strips can be above and / or below the rail transport route be attached.
  • the invention ensures that whenever one of the conveyor belts and air-impermeable tumble strips carried along the relaxation channel passed in front of one of the rows of nozzles, the one acting on the fabric here Airflow momentarily ceases, so that at that moment the sinusoidal image disturbed by the standing wave and thus a tumble impulse is exerted on the fabric becomes. It is noteworthy that the tumble stripes causing the tumble pulse be moved with the associated conveyor belt. The tumble pulse requires So no additional moving or controlled parts. It becomes easy generated by the movement of the conveyor belts.
  • the tumble strips can be placed on or in the with a smaller or larger distance Conveyor belts are provided.
  • the minimum distance between two air-impermeable strips of a conveyor belt according to the invention about one wavelength, preferably about two wavelengths, based on the Sinus shape of the fabric - amount.
  • the tumble strips provided according to the invention can be part of the Conveyor belt, e.g. integrated by appropriate weaving of the ribbon or externally applied to the respective conveyor belt and possibly at Need to be removable from the tape again.
  • Can be applied externally for example Adhesive strips that withstand the stress in the relaxation channel in question, in particular are accordingly insensitive to heat.
  • Adhesive strips are preferred so applied to the conveyor belt or belts that they through the Airflow is pressed against the single belt. So that means the respective one Adhesive tape is applied to the outside of the duct, namely to the underside of the carrier tape or applied to the top of the counter band.
  • the strip width measured in the longitudinal direction of the web the strength and effect of the tumble effect adapted to the respective needs become.
  • the duration of each can be seen by specifying the strip width Determine advantageous disorder in the sense of the present task.
  • the Stripes can be so wide that they are two (or more) in the longitudinal direction of each other Shield the following nozzles or rows of nozzles from the inside of the duct at the moment.
  • This embodiment according to the invention can be particularly interesting with the relative wide stripes if those jet streams are shielded, which are focused on a common sphere of action in the relaxation channel.
  • three fault phases can be distinguished. First occurs an introductory tumble effect when the first nozzle / nozzle row is shielded becomes. Then follows the phase with the main tumble effect, in which the two nozzles / nozzle rows shielded at the same time. In the end comes a final tumble effect in which the second nozzle / nozzle row of the one in question Is shielded from the inside of the duct.
  • 1 and 2 is a vertical section through a between two conveyor belts 1 and 2 (conveyor belt 1 and counter-holding belt 2) formed relaxation channel 3 shown. Together with the conveyor belts 1, 2 a textile fabric web 4 in its longitudinal direction 5 between below and above arranged blowing or nozzle boxes 6, 7 moved in the relaxation channel 3.
  • One Nozzle box 6 or 7 has at least one row of nozzles 8 and 9, which are transverse extends to the longitudinal direction 5 and their nozzles are directed toward the relaxation channel 3 are.
  • the nozzle boxes 6 and 7 are supplied with compressed air via lines not shown acted on, so that it via its nozzles 8, 9, preferably perforated nozzles, air jets 10 or 11 through the respective air-permeable conveyor belt 1, 2 on the Send out fabric 4.
  • the air jets 10, 11 from two on one side of the fabric Adjacent nozzle or blow boxes 6, 7 act when they - as drawn - are directed obliquely towards each other, with respect to the fabric 4 together.
  • the nozzles are arranged and acted on so that the fabric web 4th - seen in the longitudinal direction 5 - blow alternately from above and from below becomes.
  • Such a nozzle arrangement as can be seen from FIGS. 1 and 2, an approximate sinusoidal shape as a standing wave 12 in the longitudinal direction 5 Fabric 4 generated.
  • At least one nozzle or row of nozzles 8 and / or 9 is inserted Tumble strips 13 and 14 assigned. If such a tumble strip 13, 14 shields the exit jets of a row of nozzles 8 or 9 so that the associated one Air jet 10 or 11 not or not completely (in the original direction) in can enter the relaxation channel 3, this has a disturbance of the sinusoidal shape of the undulating Progress of the fabric 4 results. If there is no air jet 10 takes the effect of one entering the relaxation channel 3 from the opposite side Air jet 11 on the fabric 4 relative to. A dashed line is then created in FIG. 1 shown displacement 15 of a half wave 16 of that sine curve 17 Web wave that would occur without the strip 13.
  • tumble strips 20, 21 are provided, which - seen in the longitudinal direction of the web 5 - are so wide that they are currently both rays of the interacting Shield pairs of nozzles 8, 9 at the same time; then the two can use phases described in FIG. 1 (on arrival or departure of the one jet crossing strip) occur, but the moment is essential in which both rays of a pair of rays are shielded at the same time. Then, instead of a half-wave of the sine curve 17, a ripple can occur Flattening 22 or 23 with a large number of closely spaced small waves or adjust folds.
  • the asymmetries generated according to the invention by the tumble strips namely Half-wave displacements 15, 18 or flattenings 22, 23 are not temporal stable, but always and only available if one of them to a certain extent generating tumble strip 12 or 13 currently one of the air jets 10 or 11 shields.
  • the asymmetries 15, 18, 22, 23 therefore always appear when a Tumble strips shield a (spatially fixed) jet. Because of the alternating The individual nozzles (rows) are shielded and cleared Fabric web 4 above and below these nozzles a rhythmic air pulse sequence, which the violent movement of the fabric necessary to achieve the tumble effect evokes.
