The device producing female press-stud parts (9) includes two processing units (14). Processing units (14) have a separation section for fed parts (10), neck-forming section (11) and a feeder system (12) that conveys non-processed parts (9) in the separation section (10) to neck-forming section (11). Feeder system (12) comprises two guide rails (151, 152) and a passage (15) formed between these rails (151, 152). Sizes of the passage (15) is large enough to contain the non-processed female press stud parts (9) that move downward inside, in single file. Around the rubber wheel is a squeezable friction surface (16) having many teeth (160). Some part of this surface (160) extends into the passage (15) and forms a limited section (154) in the passage (15) between the squeezable environmental friction surface (163) and the other guide rail (152). This limited section of the passage (154) is a little narrower than each non-processed female part (9).
