ABSTRACT:
A flanged bobbin, has a central substantially cylindrical body member having an axis and two edges at each axial end. The body member is divided into at least two parts each having a first engaging formation provided substantially near the edge of the respective one of the parts, and two substantially flat discs forming lateral flanges of the bobbin and each arranged at the respective one of the ends of the body member. Each of the discs has a central aperture which is limited by an inner edge. The inner edge of each of the discs has a second engaging formation which engages a first engaging formation of the parts snugly and removably by overcoming resilience of a material of one of the body member and the disc.
