Roving frame and method of operating same

A method of operating a roving frame comprising:

• a drafting frame receiving sliver and feeding rovings to respective roving winding stations;
• respective spindles at said stations receiving core sleeves onto which respective roving bobbins are wound;
• respective flyers at said stations having pressing fingers applying roving ends to capture regions of said core sleeves and feeding respective rovings onto said roving bobbins during winding thereof;
• a drive unit operatively connected with said flyers for forming said bobbins at an operating speed of said flyers;
• and
• evaluating and control means operatively connected to said drive unit, said method comprising the steps of:
• automatically or on command, operating said flyers at a first gentle speed less than said operating speed and a speed required for automatic capture of roving ends by said core sleeves,
• automatically or on command, operating said flyers at a second gentle speed less than said operating speed, greater than said first gentle speed and sufficient for automatic capture of roving ends by said core sleeves, and
• automatically or on command, operating said flyers at a creeping third gentle speed less than said first gentle speed for startup and to position said flyers at selected angular positions.
