Abstract (en)

[origin: EP1908538A1] A coil winding apparatus (1) for forming an elongate strip (2) into an elongate helically wound coil (7) is disclosed. The present invention provides a machine which can efficiently manufacture such coils (7) to thereby increase through-put whilst at the same time eliminating the need for operator interference in the manufacturing process. The present invention also reduces the tendency for coils (7) to slightly unwind due to the elasticity of the strip (2) of material when being removed from the apparatus (1).
