The object of this invention is a device created to control the simultaneous or sequential feeding of metal bars in a guide equipment in order to feed an automatic multiple-spindle lathe.;The device consists basically of a series of drive shafts (21), each of which accounts for the feeding of a bar. These shafts amount to the same number as the lathe spindles and are placed in a drum (7) that rotates synchronously with the lathe spindle holding drum. Each of these shafts (21) can be coupled with contrivances (1) that can make it turn, when a certain length of bar is to be fed. This coupling can take place thanks to engaging and disengaging parts (49) mounted between every shaft (21) and its rotation control contrivances (1). Each shaft (21) controls at least one gear (36) accounting for the feeding of a bar, through a chain orthe like provided with a bar-pusher, when the shaft is made to turn. This gear (36) can be moved so as to make it possible to adjust and to use the device, whatever the spindle centre distance regarding the multiple-spindle lathe concerned may be.
