Spindles for twisting machines

An improved double-twist spindle mechanism of the type having a shaft rotatably supported in a fixed body, and the shaft supporting a thread bobbin carrier rotatably mounted on the top thereof, and the shaft having a hollow axial thread-receiving bore communicating with a radial thread exit bore in the shaft below the bobbin, the mechanism comprising:

• means connected to the thread bobbin carrier for supporting an upper bearing, and means carried by the fixed body supporting a lower bearing, the bearings surrounding the shaft respectively above and below said thread exit bore, and the bearings being mutually aligned along a whorl axis which is disposed at an acute angle to the axis of the shaft;
• an annular whorl member surrounding the shaft and supported at its ends by said upper and lower bearings, the whorl member having a passageway extending therethrough transversely of said whorl axis and opposite to said thread exit bore of the shaft;
• a thread driving disc surrounding the whorl member and having a radial cavity opposite to said thread exit bore;
• and
• a flange plate fixed to the disc outside the whorl member, and having a central portion extending inwardly through the passageway of the whorl member and mounted on the shaft, the central portion supporting the disc for rotation with the shaft with the radial cavity of the disc communicating with the thread exit of the shaft.
