Cotton drafting frame

A drafting frame for drafting sliver passing through the drafting frame in a direction of advance, comprising

• (a) first and second drafting roll pairs being spaced from one another consecutively in said direction of advance and each being formed of two cooperating drafting rolls;
• one drafting roll in each said drafting roll pair being a driven roll;
• (b) first and second drive motors;
• (c) first torque transmitting means connected to said first drive motor and to the driven roll of said first drafting roll pair for driving said first drafting roll pair in a forward sense for feeding said sliver in said direction of advance;
• (d) second torque transmitting means connected to said second drive motor and to the driven roll of said second drafting roll pair for driving said second drafting roll pair in a forward sense for feeding said sliver in said direction of advance;
• (e) electronic regulating means for regulating an rpm of at least one of said first and second drive motors for equalizing irregularities of the sliver;
• (f) first freewheel means for preventing a rotation of said first drafting roll pair in a reverse sense;
• said reverse sense being opposite to said forward sense;
• and
• (g) second freewheel means for preventing a rotation of said second drafting roll pair in a reverse sense;
• said reverse sense being opposite to said forward sense.
