SUMMARY

[0006] In view of the deficiencies of the prior art, the technical problem to be solved by the utility model is to provide a carding device which can avoid the distortion of the special-shaped woven material during carding and pressing and improve the production efficiency of the whole machine.

[0007] To solve the above technical problems, the utility model adopts the technical scheme of designing a special-shaped material weaving machine anti-distortion carding device: including a carding plate 1 and two pairs of card teeth 4 arranged on the carding plate 1; the front middle part of the card tooth 4 is arranged as a concave notch 5.

[0008] The notch 5 of the card tooth 4 is an isosceles triangle, and the top angle a is 30-60°.

[0009] Optimally, the top angle a of the notch 5 of the card tooth 4 is 45°.
