ABSTRACT:
An arrangement for opening textile fiber bales in which a row of textile fiber bales are broken up by at least two needle tables or rollers placed small distances apart in a row from their bottom side. The distance between the needle points of successive needle tables or rollers are continuously variable. Furthermore, the distance between needle points is changed automatically depending on properties inherent to the textile fiber bales or fiber tufts during operation of the needle table. The actual characteristic value of the detached fiber is compared with a nominal characteristic value, and a different signal is generated and applied as a control on a correcting element. The correcting element varies the distance between the needle points. Disturbance effects are obtained from the textile fiber bale, and this disturbance produces through a control device, an input or set variables for the distance between the needle points. One disturbance effect of the textile fiber bale may be the hardness.
