摘要
FIELD: textile industry. SUBSTANCE: method involves separating feeding and drawing cylinders engageable with cloth from one another so that number of cylinders is equal to number of machine outlets; kinematically connecting feeding and drawing cylinder so that each pair of feeding and drawing cylinders of one outlet is independent on other pair of feeding and drawing cylinders of other outlet; uniting each pair of feeding and drawing cylinders with individual controllable drive for rotating feeding and drawing cylinder pair of one outlet regardless of feeding and drawing cylinder pair of other outlet and kinematically coupling discharge cylinder single for all outlets and engageable with sliver to its controllable drive; preliminarily setting speed of discharge cylinder for constant value and providing cylinder speed sensors and sliver thickness sensors, the latter being arranged downward of discharge cylinder; connecting, in each pair, controllable drive with drawing cylinder; providing cloth thickness sensors upward of feeding cylinders and electrically connecting control unit of controllable cylinder of discharge cylinder to discharge cylinder speed sensor through comparison unit, and electrically connecting comparison unit inputs to all sensors and comparison unit outputs to all drive control units to provide simultaneously all needed conversions of electric signals delivered to comparison unit into signals delivered to control units for controlling all drives; preliminarily setting drawing values between each of drawing cylinders and discharge cylinder as unequal values or equal values or changing said values during drawing process regardless from one another. EFFECT: simplified operation of machine and provision for uniform precise automatic controlling of drawing process at all machine outlets. 4 dwg
