Definitions

  • the present invention relates to a device for the thermal treatment of a textile web, in particular dryer or thermal bonder, comprising at least one drum with a perforated lateral surface whose shell is at least partially wrapped by a web, wherein on the shell of the drum, a structural shell is windable, the one Has a variety of openings and / or patterns.
  • the thermal treatment of a textile web of nonwoven or nonwoven fabric includes hot air drying or hot air solidification in a flow-through, in which a heated gas, such as air, flows through the web and thereby dried or solidified.
  • a heated gas such as air
  • dryer or thermal bonders are known in which one or more drums are arranged in a housing. Through an opening in the dryer chamber, a textile web is fed to the dryer by wrapping the drum to a large extent of the circumference and then guided around the next drum and / or discharged from the dryer chamber again.
  • the web is treated, in which either fresh air blown through the web and the drum and absorbs the moisture from the web, or due to the hot air or the hot gas, a thermal Solidification of the web occurs because their fibers, for example made of polyamide, at least partially merge with each other, or a treatment of the web takes place with hot steam.
  • a smooth unstructured nonwoven fabric is produced, which can be used, for example, as topsheets for panty liners.
  • the metallic structure shell on the drum must be changed.
  • the height of the structuring in the nonwoven depends on the thickness of the shell surface of the structural shell.
  • the change of the structural shells is very complicated, since the entire structural shell is to be taken along the longitudinal axis of the drum.
  • the structural shell can have a diameter of up to 4 m and a length of up to 4.5. This is very time-consuming and labor-intensive and the Thermobonder is due to the conversion measure a longer time not available because parts of the housing if necessary. Must be removed.
  • the structural shell consists of a metallic, relatively stiff cylinder jacket, which is pushed over the drum.
  • the object of the invention is the development of a device for the thermal treatment of a textile web, comprising at least one drum with a perforated lateral surface whose shell is at least partially wrapped by a web.
  • the replacement of the structural shell is to be simplified and done in no time.
  • the invention relates to a device for the thermal treatment of a textile material web, in particular dryer or thermal bonder, comprising at least one drum with a perforated lateral surface whose shell is at least partially wrapped by a web, wherein on the shell of the drum, a structural shell is windable, the plurality of openings and / or patterns.
  • the invention is characterized in that the structural shell is formed as a band of limited width, which is wound around the drum with a plurality of turns.
  • a conventional structural shell which can have a diameter of up to 4 m and a width of up to 4.5 as a cylindrical thin hollow body, a long band of limited width is less expensive to produce than endless material.
  • the assembly of the structural shell can be done as a tape without disassembly of the drum housing, whereby production changes without longer downtime are possible.
  • the band has a first and a second longitudinal edge, which touch each other or overlap with each wrap around the drum. This creates a closed surface in which adjacent longitudinal edges are not reflected in the web.
  • a preferred embodiment provides that the band has a limited length, and the beginning and the end of the band with at least one attachment point to the drum can be fastened. This results in no overlap of the band, as in an endless belt.
  • the band has a width of 5 cm to 30 cm. This allows the tape to be wound onto a roll and is so manageable in weight and dimensions that it can be used as a single piece Installer can raise this with a jig alone on the drum.
  • the width of the band in this area allows high flexibility for drums of different diameters and widths.
  • the first with the second longitudinal edge at least in sections releasably or permanently connected.
  • This can be done by stitching, welding or by stitching, with a continuous attachment along the entire longitudinal edge is possible, but not necessary.
  • Sufficient may be a regular attachment, which is repeated in short sections offset from the adjacent longitudinal edges, for example, three to four times on the circumference of the drum.
  • the device for the thermal treatment of the web may comprise a tensioning roller, which is wrapped by the belt simultaneously with the drum, wherein the distance to the drum is adjustable.
  • the band can be mounted without great effort, the longitudinal edges are aligned with each other and then the tension roller to clamp the structural shell are operated.
  • the tape can be shrunk onto the drum, in which case the tape can only be removed destructively from the drum.
  • a wire is arranged on or in at least one longitudinal edge of the strip, which extends without interruption over the entire length of the strip. This prevents overstretching of the band during assembly and at the same time prevents bulging of the longitudinal edge.
  • both longitudinal edges of the band have a reduced thickness, which complement each other in an overlapping arrangement complete a full cross section.
  • the geometry of the reduced thickness may be arbitrary, for example wedge-shaped or in the form of a remote step or step. Since the drum and the belt stretch during operation of the thermal belt, an enlargement of the gaps at the longitudinal edges can be counteracted hereby. Clogging of the gaps or adhesion of the fibers to this gap can thus be reduced.
  • a shoulder or a wedge-shaped reduction of the cross section may be arranged at the top of the belt, and arranged on the second longitudinal edge of the complementary shoulder or wedge on the underside of the belt, or vice versa.
  • a fastening element in the overlapping region of the longitudinal edges, can be arranged or integrated at regular intervals, with which the longitudinal edges can be fastened to one another.
  • first longitudinal edge can also be positively connected to the second longitudinal edge, so that here a zipper effect can be used for assembly and disassembly.
  • Fig. 1 shows a hot air dryer or thermobonder in omega construction according to the prior art.
  • the material to be dried web 1 runs in the inlet region 4 via a deflection drum 2 in the dryer, wraps around the air-permeable designed drum 5 in a clockwise direction and runs over a further deflection drum 3 from the dryer again.
  • the web 1 may consist of a pre-consolidated web of fibers or filaments. Often the web 1 is a coming from a card pile from loose staple fibers. The pile can be transported on a conveyor belt from the card to the drum 5.
  • the tail pulley 2 can be designed as a suction drum and transports the loose pile to the drum 5 of the dryer or thermobonder.
  • the deflection drum 3 can also be designed as a suction drum in order to cool the thermally bonded nonwoven or the dried material web with ambient air again.
  • the drum 5, and the two deflection drums 2, 3 are arranged in a housing 7, in which hot air is introduced via means not shown.
  • the hot air flows through the web 1, dries this or heats the web 1 to the melting temperature of the binder fiber or other bicomponent fibers, and is sucked off by a in the drum 5 the front side, not shown fan.
  • the drum 5 is placed under negative pressure, so that different flow conditions occur in the dryer.
  • a structural shell 10 is mounted on the drum 5, which may contain a plurality of openings or patterns.
  • the structural shell 10 usually consists of a fine sheet in which the pattern was lasered. Alternatively, there are also wire mesh with a corresponding pattern. These structural shells are pushed as a thin hollow cylindrical body along the longitudinal axis of the drum 5. With a width of the web of 2.5 to 5.5 m, often a part of the dryer housing must be dismantled, which is associated with longer downtime.
  • the structural shell 10 is designed as a flexible element of a thermally resilient material, which is guided around the drum 5, led out of the housing 7 of the dryer or Thermobonders and deflected by a deflection roller 3.
  • This structural shell 10 is made in one piece and consists of a band 11 which is wound around the drum 5 in many turns.
  • the structural shell 10 can be stretched or relaxed, which greatly facilitates the replacement of the structural shell 10.
  • this structural shell 10 has a plurality of openings or patterns, so that the web 1, which leaves the dryer or Thermobonder has a perforated or patterned surface. Depending on the configuration of the system in connection with the fiber composition of the web 1, the pattern may relate to only one surface of the web 1, or both surfaces.
  • the structural shell 10 consists of a band 11 of limited width, wound in many turns around the drum 5, the longitudinal edges 11a, 11b of the band 11 either touching or overlapping.
  • the advantage lies in the ease of installation, since the dryer housing does not have to be dismantled for this purpose.
  • At the beginning or end of the assembly process arise one or two seams or attachment points 12, with which the tape 11 is attached to itself in the form of an endless belt or on the drum 5.
  • this interface or the attachment points 12 is not reflected in the web 1, the drum 5 has a greater width TB, as the working width AB of the plant or the width of the web. 1
  • the band 11 is preferably between 5 to 30 cm wide and can be stored rolled up on a roll and provided for mounting. With a drum width of 5 m results between 100 and 17 turns, whereby the working width then between 4.9 m to 4.4 m can lie.
  • a metal in the form of a wire mesh, or a glass cloth tape for example made of PTFE or a heat-resistant plastic can be used.
  • textile bands 11 are possible.
  • the bands 11 may have a raised patterned surface which impress like a watermark in the web 1 and reduce the thickness of the web 1 at this point.
  • the pattern 13 may be embedded or integrated in the band 11 in the form of apertures, at which points there is a thickening or concentration of fibers which are not fully bonded.
  • FIG. 3 shows an embodiment with an adjustable tension roller 9, with the band 11 can be tightened after wrapping the drum 5.
  • the band 11 is attached to the drum 5 with two attachment points 12.
  • the usable working width AB is smaller than the available drum width TB.
  • the tension on the belt 11 is generated by the adjustability of the tension roller 9.
  • the patterning of the belt 11 may be regular or irregular.
  • the first longitudinal edge 11a rests after a winding of the drum 5 at the second longitudinal edge 11b.
  • FIG. 4 shows another embodiment with a band 11 as patterning structural shell 10 which has been wound in turns around the drum 5.
  • the band 11 is attached to the drum 5 with two attachment points 12, so that the usable working width AB is smaller than the available drum width TB.
  • the first longitudinal edge 11a abuts against the second longitudinal edge 11b.
  • a band 11 of a slightly shrinking material for example, a film may be used, which is held on the drum 5 due to its shrinkage stress.
  • This tape 11 is to be used as a one-time solution and can only destructively removed from the drum 5.
  • the band 11 can also be made removable by making the attachment points 12 detachable.
  • FIGS. 5 and 5a show a woven belt 11 with a printed pattern 13 in the form of hemispheres, which press in the thermobonding as a depression in the web 1.
  • the woven tape 11 may be made of a heat-resistant textile, or be formed of a metallic material.
  • At least one longitudinal edge 11a of the band 11 can be reinforced with an integrated wire 16 so that bulging can be avoided.
  • both longitudinal edges 11a, 11b of the band 11 can be reinforced with a wire 16.
  • the wire 16 also has the function of preventing elongation during operation.
  • the volume 11 after the Figures 6 and 6a can be made of a heat-resistant plastic and has a plurality of regular or irregular patterns 13 in the form of squares, which penetrate into the band 11 at least partially or completely penetrate. Between the patterns 13 may be arranged in a regular or irregular arrangement, a plurality of openings 14 which are formed for example as micro-openings and penetrate the belt 11. By the pattern 13, which penetrate the band 11 in this embodiment, results for the web 1 a nub structure with raised points or areas. With the micro-openings, the surface structure of the web 1 can be influenced, since at least partially the fibers penetrate into the openings 14 and thus the surface of the web 1 is more structured and rougher. The feel of the web 1 is rougher. Also the band 11 according to this embodiment may be reinforced at one or both longitudinal edges 11a, 11b with a wire 16, which is preferably integrated in the band 11.
  • FIG. 7 shows two adjacent bands 11, which overlap in the edge region.
  • each band 11 has along a first longitudinal edge 11a a first shoulder 11c on its upper side, and along its second longitudinal edge 11b has a second shoulder 11c on its underside.
  • the longitudinal edges 11a, 11b may thus have a reduced thickness, which complement each other in a juxtaposed bands 11 to a full cross-section.
  • the paragraphs 11c are arranged so complementary to each other that a partial overlap arises, so that the top and bottom of the adjacent bands 11 acts on the web 1 substantially without interruption with a closed and flat surface.
  • the adjacent bands 11 can be fastened to one another, for example by means of a fastening element 15 in the form of a pin, or a clip (not shown).
  • the fastener 15 as a pin may be part of a belt 11, and for example fixedly attached to a longitudinal edge 11a, 11b or be integrally attached thereto.
  • the associated opening can then be integrated at the other longitudinal edge 11a, 11b in the remaining cross-section already in the pin spacings, or be produced during assembly.
  • the tapes 11 can also be fastened together at points at least at regular intervals by means of sewing, stapling, fusing or welding. An uninterrupted connection is usually unnecessary. A connection by means of plug seam is possible.
