Definitions
- the invention relates to a woven mat for ground or embankment covering, mattresses and the like consisting of a tissue of synthetic warp and weft yarns.
- Such a mat is frequently used as a base for ground or embankment covering, in which a ballast or withy is arranged on the mat with the aid of the appropriate binding or bonding means.
- a ballast or withy is arranged on the mat with the aid of the appropriate binding or bonding means.
- the mats In view of the ever large units dragged from the homestead or factory to the place of destination the mats must have an ever increasing tensile strength. Attempts have been made to manufacture composite structures consisting of a synthetic mat with metal gauze. The manufacture of such structures is expensive.
- the invention has for its object to provide a woven mat of high tensile strenght, which can be made in a simple manner on a loom.
- the mat according to the invention is distinguished in that a few warp yarns are replaced by a solid warp wire of metal.
- the solid metal-warp wire proposed by the invention imparts to the mat the required tensile strength and, in addition, owing to the greater rigidity as compared with the synthetic resin yarns it directly becomes a solid warp during the weaving operation, that is to say this warp in contrast to the binding warp is not bent in zigzag fashion about the weft yarns and is hardly likely to lengthen.
- the metal warp wire is formed by a twined steel cable.
- the woven mat maintains a given amount of flexibility so that it can match unevennesses of the ground.
- the steel cable employed in accordance with the invention may be left- or right-woven and any suitable construction of the steel cable may be used, for example, the Lang's lay cables or regular lay cables.
- the invention furthermore proposes to provide the synthetic binder warps located at the side of the solid metal warp in a diameter corresponding to said solid metal warp. This will result in a more gradual change-over from the weft wires from the normal mat tissue to the metal warp, which is at the same time conducive to the density of the mat tissue so that a more uniform permeability of the mat to water is ensured.
- binding or bonding means are woven during manufacture thereof, said binding or bonding means serving for fastening withies or other ballast material, for-example, cast concrete blocks on the mat.
- the invention proposes to pass the binding or bonding means along the rear side of the solid metal warp with respect to the ballast side of the mat. Owing to this measure the forces exerted on the withy or the ballast will be substantially directly transferred to the strong metal warp wires.
- the mat may furthermore be advantageous in accordance with the invention to cause the solid warp on the ballast side of the mat to float with respect to the mat tissue at regular intervals.
- These floating steel wire portions may then be used for fastening ballast material by passing bonding means in between the mat and the steel wire.
- the mat may have any suitable shape and any known weaving technique may be employed for obtaining certain, known weaving structures.
Abstract
Description
- The invention relates to a woven mat for ground or embankment covering, mattresses and the like consisting of a tissue of synthetic warp and weft yarns.
- Such a mat is frequently used as a base for ground or embankment covering, in which a ballast or withy is arranged on the mat with the aid of the appropriate binding or bonding means. In view of the ever large units dragged from the homestead or factory to the place of destination the mats must have an ever increasing tensile strength. Attempts have been made to manufacture composite structures consisting of a synthetic mat with metal gauze. The manufacture of such structures is expensive.
- The invention has for its object to provide a woven mat of high tensile strenght, which can be made in a simple manner on a loom.
- The mat according to the invention is distinguished in that a few warp yarns are replaced by a solid warp wire of metal.
- The solid metal-warp wire proposed by the invention imparts to the mat the required tensile strength and, in addition, owing to the greater rigidity as compared with the synthetic resin yarns it directly becomes a solid warp during the weaving operation, that is to say this warp in contrast to the binding warp is not bent in zigzag fashion about the weft yarns and is hardly likely to lengthen.
- In a preferred embodiment of the invention the metal warp wire is formed by a twined steel cable. Thus the woven mat maintains a given amount of flexibility so that it can match unevennesses of the ground. The steel cable employed in accordance with the invention may be left- or right-woven and any suitable construction of the steel cable may be used, for example, the Lang's lay cables or regular lay cables.
- Particularly for the case of comparatively thick warp wires of metal or thick steel cables the invention furthermore proposes to provide the synthetic binder warps located at the side of the solid metal warp in a diameter corresponding to said solid metal warp. This will result in a more gradual change-over from the weft wires from the normal mat tissue to the metal warp, which is at the same time conducive to the density of the mat tissue so that a more uniform permeability of the mat to water is ensured.
- In hydraulic engineering woven mats have been employed in which binding or bonding means are woven during manufacture thereof, said binding or bonding means serving for fastening withies or other ballast material, for-example, cast concrete blocks on the mat.
- For such a mat the invention proposes to pass the binding or bonding means along the rear side of the solid metal warp with respect to the ballast side of the mat. Owing to this measure the forces exerted on the withy or the ballast will be substantially directly transferred to the strong metal warp wires.
- In a further embodiment of the mat it may furthermore be advantageous in accordance with the invention to cause the solid warp on the ballast side of the mat to float with respect to the mat tissue at regular intervals. These floating steel wire portions may then be used for fastening ballast material by passing bonding means in between the mat and the steel wire.
- Irrespective of the above-mentioned features the mat may have any suitable shape and any known weaving technique may be employed for obtaining certain, known weaving structures.
