In Switzerland March 28, 1950 My present invention relates in general to 'multi-head machines for spinning, twisting,

winding, finishing, and dressing yarns "and and in particular to' pneumatic clearing apparatus applicable to such machines for removing and confining dust, fluff and like waste products.

The apparatus disclosed by my present invention comprises a trap sheet disposed within the range of the moving threads and intended for collecting the dust, fluff, and the like, and a blower-operated air-conduit system for maintaining a blowing and a 'sucking action within the range of said trap sheet. The said system suitably is so constructed and, during operation of the machine, so moved automatically on a track that the trap sheet isperiodically cleared from the accumulated waste at each operating head of the machine.

My present apparatus efiectivelyremoves fiber "Fig. 3 partial rear""elevation as, seennm the left of Fig. 1', f v,

After the package LWOUlfld uponpirn a (whichsubsequently is to' be used in a shuttle) has reached a predetermined'size,

the element I is rotatedfthrough one 'stept'o present an emptypirnf-a, to said head. The winders B are driven fro'm a common rnotpr (not shown) through an endless belt'fl which 'riins' 'on two idling or rve'rsmg sellers disposed at'the I2 formed in plate 9 a friction roller 5 drives'the main shaft B of each winder B. The pirn'a situated in the operating head is supplied with-thread b through a brakeand-guide mechanism I; Thread b is 1 derived from a supply bobbin 0 -mounted on a-holder 8 which is disposed on the machine frame.

Below the supply-bobbins c-there is provided a rearwardly ascending sheet-iron trap plate 9 which is securedto frame A; and covers allthe winders B. --"Ihe said plate 9 on the machine frontside has an upwardly bent border lllfwhich is parallel to the rearborder I I.

'Also above the tra'p' pl ateQ fis disposed anelongated brings ZfI h'a ving two parallel suction pipes '28 which 'prdt'riidihto the'head'of said chamber 20. I The orifice 2I *with 'its"respective mouth "is disposed parallef'to the longitudinal trap-plate nun and-adjacent'th latter. 'A'ffilter bag :23 is; o'osly' suspen edfin said chamber '20 and ifs 'a'c ssible fr 'I'nthe outside after removing: a cover 19 associated 7 with the box I 9, in order" to be removed fro'mth'e latter andemptie'd. 'A sucnonpartsnnra blower 3| disposd in the foot of air tluct"ilfpi'ojectsinto chamber 20. The blower-3! is' operated by an electric' motor 32 secured to stand I3. h mouths of two paral lelblo'w pipes'33 springing from-air 'duct ZI, are situated within the range of the rearward free border -II' of rap ing 9 v lwitfiinotor'fl switchedon, the blower3I produces an upward air current in duct Z I "the; major portion of said 'ciirrent" 'reachiiig the orifice 24 'through'tube na fidhos'e zi'and beirig'discharged from said orifice through the blow elements 25 and 26. This air current is conducted on the top side of plate 9 substantially transversely toward the orifice 21 of the suction-pipe pair 28, partly impinging against the longitudinal rib I2 of plate 9 and beingdeflected thereby towards the orifice 21. A portion of the air current flowing upwardly in duct 2i passes through the two blow pipes 33 and then across the top side of plate 9 against the rib 12 thereof, vvhreby it also is deflected towards the orifice 21-. Within the range of rib l2 the air currents flowing in opposite directions impinge on each other, thus- 3|. In the conduit system formed by box l9 and the parts and portions associated therewith, air thus is cycled continuously whereby the catch plate 9 is cleared of fluff by virtue of the cooperation of induced-draft air and forced-draft air.

In order to clear in the manner described the catch plate 9 within the range of all the winders B, i. e. the entire top side of plate 9, the stand i3 during such clearing operation is wheeled back and forth on the rails 15 and H of the machine frame A so as to periodically clear all the machine operating heads of fluff. For such purpose, the stand l3 througha link 34 is connected to an endless chain 35 which is driven by the motor (not shown) which operates the machine. The chain 35 runs over idling rollers 36 (Fig. 3) which are spaced a certain distance from each other on the machine frame A. When the stand I3 has covered its operating distance, whereby it has passed slightly beyond the respective reversing roller of chain 35, the stand (after a temporary standstill) is run back, as will be readily appreciated. I V V In the modification shown in Figs. 4 and 5, the trap plate 31 comprises an upper marginal rib 38 on its rear border which rib replaces the longitudinal rib i2 on trap plate 9 of the first example. Within the range of rib 38 is disposed an orifice 39 of asuction pipe 49 which communicates with the chamber 29 of boxi9 and forms a transverse head on the suction pipe 40. An orifice M is connected to hose 23 of the forced-draft air line and comprises a central blow tube 42 and two lateral blow tubes 43 (Fig. p

In this form of invention, the air flowing from orifice 4| through the tubes 42 and 43 across the top side of plate 31 is blown towards the marginal rib 38 of plate 31 and, thus, towards the orifice 39 of suction pipe 49. The air flows through the latter into the chamber 20 of box I!) which is fixed to the stand I3, and then through the filter bag 28' (as in the previous example) into the suction part of the blower. The construction and mode of operation of this modification otherwise are similar to those of the first example.

The stand l3 which is movably mounted on the machine frame A, may be that shown by pendin application Serial Number 204,176, filed jointly by applicant and Kaspar Laager on J anuary 3, 1951, which application discloses the frame as carrying bobbin pay out means which is automatically supplied by a stationary or a mobile feeder. As disclosed by said pending ap plication, the feeder has a magazine for empty bobbins, and during its run automatically supplies empty bobbins to the individual winder as required in accordance with the winding operation or, respectively, with the automatic copchanging motion on the winders. The machine could be soconstructed that the bobbin pay-out means or stand i3 respectively, instead of mov ing back and forth on a track of given length, is moved unidirectionally on a closed track. In such arrangement, the bobbin pay-out means supplies empty bobbins for example to two rows of winders arranged opposite to each other on the machine frame A, the fluff suitably being removed from the two rows of winders. The machine shown and described may be varied in other details also. For example, the blower 3| instead of being driven by a separate electric motor, may be driven from the driver motor, for example di rectly by means of the driving belt 4.

What I claim as new is: H p
