  • Process and machine for manufacturing elastic bands as well as bands thus obtained
    Patent number: 5600973
    Abstract: Process and machine for manufacturing elastic bands with small diameter tubular fabric knitting machines of the single-feed type with fixed needle cylinder and revolving cam drum, wherein a bobbin holder of an elastic thread is autonomously supported above the needle cylinder and coaxial with respect to the needle cylinder. The revolving drum has a taking arm which guides the elastic thread and the inelastic thread without mutual contact up to the immediate vicinity of the needle cylinder. A sensor detecting the diameter change of the elastic thread cylindrical bobbin is operatively connected to a driving device with regulated speed control which keeps constant the elastic thread feed. The tubular bands obtained are knitted bands with at least one inelastic thread and at least one bare elastic thread.
