FIELD: materials.SUBSTANCE: invention relates to draw plate for making glass fibre. Draw plate device comprises a draw plate, including lower plate with multiple holes. Bottom plate has a longitudinal axis, wherein at the first side of lower plate there is a first side wall extending perpendicular to longitudinal axis, and at second side of lower plate there is a second side wall, also extending perpendicular to longitudinal axis. Draw plate device comprises at least one elongated support extending through at least one element to receive supports of draw plate along longitudinal axis and by means of which to lower plate of draw plate an upward force is applied. Lower side of support is arranged directly above upper surface of lower plate. Each of elements for receiving supports comprises a plurality of connectors, connecting element for receiving supports with lower plate between first side wall and second side wall. Support is made of ceramic based on aluminium oxide.EFFECT: technical result is reduction of deformation of draw plate during its operation.20 cl, 10 dwg |
