A grinding member (100) comprises an elongated support profile (110), the cross-section of the support profile (110) comprising a vertical direction (S1) and a lateral direction (S2), whereby the cross-section of the support profile (110) has at least one portion (112) the dimension of which is, in the lateral direction (S2), greater than the corresponding greatest dimension, in the lateral direction (S2), of the portion (111) above it in the vertical direction (S1), whereby the support profile (110) can be engaged with a groove (20) having a corresponding cross-section; and an elastic grinding plate (120) fastened to the portion (111 ) positioned highest in the vertical direction (S1) of the cross-section of the support profile (110) and protruding from the upper surface of the support profile (110). |
