Abstract: 797,382. Winding cops. ETIENNE MOTTE FILS & CIE, and MOTTE, J. C. M. J. Jan. 4, 1956 [Jan. 18, 1955, Aug. 24, 1955], No. 322/56. Class 120(2) In winding cops continuously over a common spindle, a gap is formed between the successive cops through a movement of the cop just produced in relation to the spindle or the funnel, pressure cone or like winding member having for its dual purpose the shaping of a cop and the translational shifting of the latter over its spindle so that it is possible to cut the thread between the successive cops and to remove the formed cop thus separated. As shown in Fig. 1, a thread 8 fed from a spinning pot 5 through a stretching device 9 and guide 10 is wound into a cop 2 within a funnel 3 on a spindle 4. When a cop is completed, a handle 24 is pulled upwardly to cause the funnel (and the cop carried thereby) to make a rotary movement along a helical line as guided and limited by a fixed screw 22 engaging a slot 23 in a funnel extension 17: on release of the handle, the funnel is returned by the spring 19, leaving the cop in its raised position on the spindle around which are some loose thread convolutions (formed during these movements of the funnel and the cop) which facilitate separation between the completed cop and the cop then commencing. In a modification, Fig. 5, depression of a forked lever 27 from a horizontal position causes the spindle 26 to slide downwardly within a wound cop 25 and on return of the lever 27 a spring 31 restores the position of the lever 27, funnel 34 and spindle 26, leaving the cop in raised position on the spindle with loose turns of thread therearound. In another modification, Fig. 7, the separation between two successive cops is obtained by depressing a lever 37 so that a cam 38 bears on and depresses a ring 39 which lowers the spindle 41 with reference to the cop 45 which is held by a stationary funnel 35: a spring 42 restores the apparatus with the cop vertically displaced on the spindle. In apparatus for automatically raising and rotating the funnel, Figs. 10 and 12 (illustrating the operation before and after formation of the cop), a pivoted feeler blade 78 is engaged by a cop being completed and raises a feeler rod 82 which produces, through its hook-shaped end 83 a lift of the bar 86 (rigid with a lever 84) engagement of which by a reciprocating lever 66 on its forward stroke causes a rocking thereof in the direction of a funnel 52. The lever 66, thus raised from and no longer carried by a lug secured to a support 61, in its continued forward movement is unimpeded by a pivoted stop 75 which has been rendered inoperative by being urged downwardly as it passes underneath a projection 59 on the funnel: however, when the lever 66 is moved to the rear, the flap 75 assumes a position in which it engages the projection 59 so as to cause the simultaneous rotary and rising movement of the funnel and, simultaneously therewith, a stop 73 which has prevented the complete rearward rocking of the relay lever 84 returns the latter into its starting position without its being re-engaged by a projection 72 since the blade 78 and rod 82 have meanwhile been angularly shifted by a projection 58 on the funnel during the rotation of the latter. In the apparatus shown in Fig. 14 whereby the gaps between cops is obtained by merely raising the funnel, completion of the cop lifts the blade 78 so that a feeler rod 101 raises a relay lever 99 which is thereafter caused to rock by the projection 97 and raise the reciprocating lever 95: the latter, in its rearward movement, produces through a pivotal flap 98 a rocking of camlevers 93 and thus an uplift of the funnel 92. On movement of the lever 95 in the direction of the arrow 105, its projection 96 urges a projection 103 to produce a rocking through 90 degrees of the system including the rods 101 and 102 and the feeler 78. The apparatus shown in Fig. 16, whereby the gap between cops is obtained through a lowering of the spindle, differs from that of Fig. 14 only in that two cams 106 pivotally secured at 107 to a funnel 108 bear against a stop 109 rigid with the spindle 110 and serving as an abutment for one end of a spring the other end of which engages the stationary support 111 so that the spindle is urged to its normal position.
