Definitions

  • This invention relates to a fabric tube, a method of manufacturing the fabric tube, and application of the fabric tube.
  • the tube is applicable for use in holding and conveying fluid and other flowable materials, such as mine and tunnel ventilation ducting for supplying air into remote underground mines and other enclosed spaces. It will be convenient to hereinafter disclose the invention in relation to that exemplary application. However, it is to be appreciated that the invention is not limited to that application.
  • WO2005/075186 discloses a fabric which, in a tube form, is applicable for use as mine and tunnel ventilation ducting.
  • that tube has an inner first layer which is blow moulded from polymeric plastics material into a tubular shape, and an outer second layer laminated to the inner layer.
  • the outer layer is composed of two elongate sheets of woven polymeric plastics material, each sheet extending longitudinally along and laterally partway about the inner layer. Opposite edge regions of each elongate sheet overlap and are joined together face-to- face so as to form diametrically opposed fins extending along and projecting from the outside of the tube.
  • a hot melt adhesive is used to adhere the layers together as well as the edge regions of the elongate sheets.
  • the tube can be suspended by one or both fins along a wall or roof so as to deliver air into the mine or along the tunnel. Eyelets can be provided in spaced apart relation along the fin(s) to facilitate that suspension.
  • the tube disclosed in WO2005/075186 exhibits good performance characteristics in most ventilation ducting situations. However, it has been found that the integrity of the joined edge regions of the outer layer sheets may be inadequate in some situations. In particular, the air pressure in the tube at the fan head, or inlet end of the ventilation ducting, may be above a level which can be safely handled by the tube. Excess internal pressure can cause unexpected loading at the fin joins, and may lead to localised delamination or separation of the edge regions. When that occurs, the unsupported inner blow moulded layer is not sufficiently strong to resist the air pressure, and so the tube may burst.
  • It is an object of the present invention is to provide a tube which is applicable for use as ventilation ducting, and which displays better burst resistance.
  • It is another object of the present invention is to provide ventilation ducting which is better suited to positioning at the fan head and other regions of increased air pressure.

  • the elongate sheets of material is composed of woven sheet material.
  • a method of manufacturing a fabric tube including: weaving a base layer having an integrally woven tubular wall and at least one fin extending along the wall and projecting outwardly therefrom; and laminating at least one covering layer to the base layer in order to provide a tube with applicable characteristics.
  • the base layer is flat woven in the weaving step of the method of the present invention. More preferably, in the weaving step, the base layer is formed by two fabric sheets each having overlying longitudinal edge regions which are progressively woven together as part of the weaving process joining the fabric sheets together, the interwoven edge regions providing the at least one fin.

  • the method of manufacturing a fabric tube of the present invention preferably further includes the step of applying a film coating(s) to the base layer as inner covering layer(s). In one embodiment, this step is conducted using a blown film lamination process.
  • the covering layer includes sheets of material
  • these sheets of material are laminated directly or indirectly to the base layer by adhering the sheets to the wall and fins of the base layer.
  • the lamination step is conducted by applying a hot melt material process.
  • the laminating step the base and covering layers are laminated by passing the layers between pressing rollers.
  • the base layer is preferably passed through the pressing rollers twice, a first covering layer being applied to a first outer surface of the base layer during a first pass and a second covering layers being applied to a second outer surface of the base layer during a second pass.

The overlying edge regions 38 and 39 are interconnected by progressively weaving these edge regions 38 and 29 together as part of the weaving process. The interweaving of the overlying edge regions join the fabric sheets together to form the tubular shape of the fabric 10. Thus, the sheets 12 and 13 are not only simultaneously woven, but also simultaneously interwoven along their corresponding edge regions 38 and 39.

  • the roller set in some embodiments can include at least one chilling roller for cooling the hot melt material after the layers 20, 22 and/or 24 are pressed together, thereby fusing the layers 20, 22 and/or 24 together.
  • That roller may be one of the rollers between which the layers 20, 22 and/or 24 are initially pressed together, or a further roller located downstream thereof.
  • That sheet covering layer may be in addition to film coating layers applied to the outside and/or inside of the base layer.

Abstract

La présente invention concerne un tube en tissu (10) et un procédé de fabrication d’un tube en tissu (10). Le tube en tissu (10) comprend une couche de base (20) comportant une paroi tubulaire intégralement tissée (18) et au moins une ailette (14, 16) s’étendant le long de la paroi (18) et faisant saillie vers l’extérieur à partir de celle-ci ; et au moins une couche de couverture (22, 24) stratifiée sur la couche de base (20) afin de fournir un tube (10) ayant des caractéristiques applicables. Le tube en tissu (10) peut particulièrement être utilisé en tant que colonne de buses d’aérage de mine et de tunnel.
