| » The thread roll | |||||||||||
| The thread roll is to produce and assemble textile fibres. The product is perfectly axial, balanced and without superficial roughness. Everything is done in function of this aim, from the components mixing to the furnace centrifugation, with specific processes the incorporation of the flanges in the resin in order to realize a perfect coupling between the thread roll and the drier. | |||||||||||

| Chemical properties
|
|||||||||||
| Resistance to the chemical agents involved in process like the sulphuric acid, carbon sulphide, sodium sulphate and sodium hydroxide. Working temperature between 20° and 120° |

| Geometrical characteristic: |
|||||||||||
Up to 2.000 mm length Diameters included between 50 and 500 mm Diameter tollerance+- 0,04mm Shifting of the thread roll axle < of 0,1 mm during the working process |

| Mechanical characteristic: | |||||||||||
Lack of vibrations during the operation (frequency of resonance of the first harmonica < of 10for operating frequency) Operating frequency= to tip speed / (6,28 x r) where r is the thread roll radius Surface hardness equal to at least the 80% of the quarts one The thread rolls do not cause the breaking of the threads Coupling between flanges and thread rolls in order to guarantee a transmissible couple value bigger than the load couple Statical and dynamical balanced thread roll and supports Average life in working conditions > 25.000 h |
