The present invention relates `to an arrangement in combing machines byimea'ns of which many disadvantages are removed and several advantages are-gained.' Iiiste'ald off arranging af combing segment and adetacli-fing segment on the lsame combing cylinder, the combing and detaching members are according to vthis invention arranged each on its own cylinder orther like, whiclijcylinders 19 are' coaxial' and are operated independently of each other Ywith suitableadjustable speeds. Hereby it is possible to reach a more effective-L andV quicker combing as considerably higher speeds can 'be vgivento the combing cylinder;

fThecombing cylinder can be provided'with .needlesof'lthe samesize 'and c'oarseness suitably arranged around the whole' surface ot' the cylinder.y Previously only` a certain part ofthe cylinder surfacecorresponding to the Y l known movably arranged jaws 4" and -5 will 20T curve .length of the'combing segment could be utilized for theV combing of each fibre piece, whereas with the present invention the fibre piece will be subjected to a'continuous uniforni combing of considerab'lylarger comb .'surface, namely the surface corresponding to that part of the circumferencev yofthe comb cylinder that has time to pass before they de-'f ta'ching segment covers the needles onthe combing cylinder. v

cylindrical surfaces that arepartsoi:l aylinr der coaxial with and embracing the combing Ygreater than the outer diameter oi' the combing cylinder. that participates in the combingy action'rwill thus be dependent on thespeed oftheco'mbing cylinder.l Said effectivecomb surface-- can amount to y'severaltimes .the whole sur-` face of the combing cylinder'k or onlyla part thereof dependingfon the oircumstances.

The invention hasthezfollowing advantages: Y The libre pieces ldo notvn'eedvto` be com pletely clean-carded. i

The fibre pieces do not need y'to-*be thin:y to

be completely combed through. They can be considerably 'thicker and d'irt'ier' than before',

der.' The heretofore necessary mechanism can be of the same kind as 1n hitherto known combing machines. Said mechanism is so 4adapted that, when the sector 9 enters be tweenl theV fibre piece and ftheV needles, V-the roller 10 is moved against the segment 9l so that the fore end of the iibrepiece-is seized betweenlthe roller and the segment which during the continued rotation hold thefbrf piece and carry it forward. rtheA fibre piece before this the jaws l and5 Yhavein the known way beenseparated from the'14 'fibre' J tation has'just been reversed so that they are feeding backthe aft end of the fibre piece. During this motion this'end of the fibre piece:

' will be combed ready. After'` the completion of the lcombing of the fore end ofV the fibre piece 3- as described above Vthe roller 10 and the segmenti) carrythe same forward'sothat its fore erfdwill overlap theba'ck endy of the previously combedr fibre piece which now lhas been returned by the rollers" Hand-12, so that an effective'joining'is the result-('see` Figure By means of the said .mechanism the direction of rotationf the-rollers 11' andf12 is then reversed and the fibre pieces are transported further.

When the combing of the fore endrof Vthe fibre piece has been lcompleted (as described abo-ve and thesame has been seized by the-roller 10and the segment 9, the'coi'nb 14 is lowered by 'a known'mechanism into the path of the fibre piece so that when the latter v is carried forward, it is drawn through. the needles ofthe comb 14 and properly treated.f However,z this top comb" -14 also be y omitted andl the combing of the aft end Vof i the libre piece be carried out by the combing" cylinder aloneV when the fibre piece is Vreturned bythe rollers 11 Vand 12 as described" above. i i "f VFigure 3 shows one way of arranging-the' combing cylinder andthe detaching segments in relation' to each other.
