Funnel for a spinning machine

In an apparatus for delivering yarn for building a package on a spindle of a spinning machine, a funnel comprising:

• a neck portion defining a yarn entry channel and a coaxial annular funnel body portion defining an open interior area communicating at one end of said funnel body portion with said entry channel of said neck portion and open at the opposite end of said funnel body portion for receiving said spindle, said funnel body portion defining a yarn exit opening at an axial spacing from said entry channel of said neck portion and having an exterior yarn guide surface extending axially from said yarn exit opening to said opposite end of said funnel body portion, said yarn entry channel of said neck portion being adapted for delivering yarn into said interior area of said funnel body portion and said exit opening of said funnel body portion being adapted for passage of yarn from said interior area of said funnel body portion to said exterior yarn guide surface thereof, said yarn entry channel being of a sufficiently constricted cross-section for the passage of yarn therethrough in a substantially longitudinal path into said interior area of said funnel body portion, said interior area of said funnel body portion being of a sufficiently enlarged cross-section in relation to said entry channel of said neck portion and in relation to said spindle and said exit opening of said funnel body portion being sufficiently spaced from said yarn entry channel of said neck portion for causing yarn to balloon while traveling within said interior area of said funnel body portion between said entry channel of said neck portion and said exit opening of said funnel body portion, the cross-section of said interior area of said funnel body portion controlling the amount of yarn ballooning.
