摘要： PURPOSE:To keep the amount of cotton in each hopper at a nearly constant level and to reduce the time loss in the change-over of the feeding raw material fiber, by selecting the feed hopper by a specific standard and carrying out the cotton feeding for a specific preset cotton feeding time. CONSTITUTION:A level above the cotton level in a hopper 3 containing least cotton by one rank is set by a judgement part 9 of a sequencer 6 as a target cotton feeding level. Only the distribution damper of the hopper having lower cotton level than the target cotton feeding level is opened and the feeding of cotton is stopped when the level reaches the target level. When all hoppers reach the target cotton feeding level, a new target cotton feeding level is set and the feeding of cotton is carried out in the similar manner. The preset cotton feeding time of each hopper is divided into plural sections using the actual feeding time of the same level sections to be fed with cotton and the levels are calculated to effect the control of the cotton level in each hopper in high accuracy at a level corresponding to a division of the original level.
