Device for producing a fibre mat by weaving

Abstract

The invention relates to a device for producing a fibre mat by weaving, which fibre mat is built up of a substrate on which fibres are provided and which device is provided at least with means for forming a shed of warp yarns forming the substrate of the fibre mat, a lay as well as means disposed on one or both sides of the shed for inserting one or more weft yarns into the shed. The invention further relates to a fibre mat obtained by means of a device according to the invention.

1 .

         4 . A device according to  claim 3 , wherein the cutting surface of said at least one knife element extends perpendicularly to the insertion direction of the weft yarn. 
     
     
         5 . A device according to  claim 3 , wherein the cutting surface of said at least one knife element extends at an angle to the insertion direction of the weft yarn. 
     
     
         6 . A device according to  claim 3 , wherein said at least one knife element is fixedly disposed. 
     
     
         7 . A device according to  claim 3 , wherein said at least one knife element is movably disposed. 
     
     
         8 . A device according to  claim 7 , wherein said at least one knife element conducts a scissor movement. 
     
     
         9 . A device according to  claim 7 , wherein said at least one knife element is rotatable. 
     
     
         10 . A device according to  claim 9 , wherein the cutting means comprise at least one rotatably driven shaft provided with several spaced-apart knife elements. 
     
     
         11 . A device according to  claim 10 , wherein the spacing between said knife elements is adjustable. 
     
     
         12 . A device according to  claim 1 , wherein the device comprises support means for the weft yarns, which support means cooperate with the cutting means. 
     
     
         13 . A device according to  claim 12 , wherein the support means comprise at least one rod member, over which the weft yarns to be cut through can be passed. 
     
     
         14 . A device according to  claim 13 , wherein said rod member is provided with a recess which is capable of receiving at least part of the cutting element. 
     
     
         15 . A device according to  claim 12 , wherein the support means comprise at least one wire-like support guide supporting the weft yarns, which wire-like support guide is connected to the free end of a rod member with a first end and to the lay with another end. 
     
     
         16 . A device according to  claim 15 , wherein the free end of said rod member is screw-connected to said rod member. 
     
     
         17 . A device according to  claim 15 , wherein said wire-like support guide is connected to the device with its other end by means of a spring element. 
     
     
         18 . A device according to  claim 12 , wherein said support means are tiltable relative to the shed. 
     
     
         19 . A device according to  claim 15 , wherein said wire-like support guide is made of a plastic material. 
     
     
         20 . A device according to  claim 15 , wherein said wire-like support guide is made of a metal. 
     
     
         21 . A device according to  claim 1 , wherein said cutting means cut said one or more weft yarns through in one or more places using ultrasound. 
     
     
         22 . A device according to  claim 1 , wherein said cutting means cut said one or more weft yarns through in one or more places using heat. 
     
     
         23 . A fibre mat obtained by means of the device according to one or more of the preceding claims.
