1, 033, 232. Knitting-machines. M. S. MORETTA. [trading as MORETTA OFFICINE MECCANICHE FABRICA SPECIALIZZATA MACCHINE PER CALZE DI SESSA MARCELLA.] June 19, 1964 [June 22, 1963], No. 25358/64. Heading D1C. A pneumatic tensioning device for a circular knitting machine comprises means to produce an airflow in an upward direction which pulls the tubular knitted fabric directly into an external tube 18, without allowing the fabric to enter the needle cylinder, the external tube 18 being arranged eccentrically with respect to the axis of the needle cylinder. In Fig. 3 the airflow is created by a fan 23 and a tube 19 mounted within the needle cylinder. In a modification Fig. 5 (not shown) the airflow is produced by connecting the tube 18 directly to an external source of suction or low pressure, a trap being provided to remove the articles produced from the intermediate piping before reacting the suction fan. |
