PERFEZIONAMENTI NEI DISPOSITIVI ANTIPALLONE PER MACCHINE FILATRICI CONTINUE. |
摘要 |
In a spinning or twisting machine, a anti-balloon ring stationarily fixed around the bobbin spindle is first sand-blasted so as to produce a predetermined degree of surface roughness, then provided with a nickel coating in order to reduce undesirable excrescences followed by a copper coating in order to reduce friction and loss of yarn resistance while permitting much higher spindle speeds in respect of an acceptable rate of wear. |
