Abstract: An arrangement for opening textile fiber bales in which a row of bales are broken up from their underside. The device which performs the breaking-up process has revolving pairs of needle tables or rollers with needles inclined in relation to the working direction, so that with adjacent break up members they are inclined in the opposite direction. The rotary speed of the needle table is variable, and the rotary speed of one needle table of at least one pair of tables or rollers is changed as a function of material-specific property of the textiles fiber bales. The rotary speed may be changed automatically during operation. An input control parameter is obtained from the textile fiber bales to generate an input variable for the rotary speed of the needle table, through a control unit. The hardness of the textile fiber bales may be used as the input control parameter. The weight of the bales may also be used for this purpose of providing the input control parameter.
