- FIG. 16 is a section through the stopper element, taken on the line XVI of FIG. 14.
- With reference initially to FIG. 1, a subassembly according to the present invention, for simultaneously serving a series of compacting units in a spinning machine comprising a plurality of spinning stations side by side (not shown), is generally indicated10. Reference will be made in the following description to an embodiment in which the unit is shared by a series of eight spinning stations, but this number should not be considered as limiting of the scope of the patent.
- The subassembly10 comprises a fixed
transverse tube 11 of circular cross-section which has, for each spinning station, anarrow suction slot 12 disposed on the path of the roving and along its direction of advance, defined herein as the longitudinal direction. The terms “longitudinal” and “transverse” as used herein should be interpreted with reference to this direction unless indicated otherwise. - As shown in FIGS. 2, 4 and5, the
tube 11, which is preferably made of stainless steel, has an outlet opening 13 which is elongate in a transverse direction and is disposed in a central position in order to put theslots 12 into communication with a suction source located in a remote position and not shown for simplicity. In the rim of each of its opposite ends, thetube 11 has a locating notch 14 (visible in FIGS. 2 and 3) formed in a predetermined angular position relative to the outlet opening 13. - With further reference to FIG. 1, a sleeve or
manifold 15, shown in isolation in FIGS. 6 to 9 and in communication with a suction source (not shown), is mounted centrally on thetube 11 in the region of theopening 13. Themanifold 15 comprises atubular portion 16 which is clamped onto thetube 11 so as to be perpendicular thereto. Themanifold 15, which is preferably made of plastics material, has aclamping band 17 which extends around thetube 11 and is engaged by a hookedportion 17 a on aprojection 18 formed by the manifold so as to clamp the manifold on thetube 15. The manifold has an inlet opening 19 of a shape matching that of the opening 13 of thetube 11 in order to be coupled therewith. A locatingstep 20 for insertion in the opening 13 of thetube 11 is preferably formed in the region of the inlet opening 19. The sleeve advantageously has a seal at the interface between the inlet opening 19 and the opening 13, to improve leaktightness. - As can best be seen in FIGS. 7 and 9, immediately downstream of the inlet opening19, the
manifold 15 has an outer pair of opposedtransverse projections 21 which, together with the outer surface of thetube 11, define a pair ofseats 22. Theseats 22 serve to lock the ends of a pair of tensioning units, as will be explained further below. - With further reference to FIG. 1, each
slot 12 is covered, with a wide margin, by a respectivemovable filter loop 23 disposed around thetube 11; thefilter loops 23, which are made of textile material and in any case are permeable to air, are circulated about thetube 11, in use, by pressure rollers (forming part of the compacting unit and not shown) which press the rovings against the filter loops. The above-mentioned pressure rollers are known in the art and do not therefore need to be described in detail herein; for the construction of the parts and of the elements of the spinning machine which are not shown, reference may be made to co-pending U.S. patent application Ser. No. 716,458 which is incorporated herein by reference. - The path of each filter loop is defined by a portion of the surface of the
tube 11 and by aguide bar 28 provided with a resilient element 25 for keeping thefilter loop 23 taut. - Each unit according to the present invention has two tensioning units, each of which is generally indicated26 and which are fitted along the
tube 11 on opposite sides of thecentral sleeve 15. - With reference to FIGS. 10 and 11, each
tensioning unit 26 comprises abase 27 for bearing on thetube 11, to be placed close to the outer surface of the tube and locked releasably thereon. Thebase 27 preferably has an arcuate cross-section in order to fit the cylindrical outer surface of thetube 11. Thetensioning unit 26 carries a plurality of individualtransverse guide bars 28, one for eachfilter loop 23. Thebars 28 are uniformly spaced apart transversely and project longitudinally from thebase 27, to which they are connected by respectiveresilient elements 29 for tensioning the filter loops; in order to keep the filter loops correctly aligned in positions in which they cover theslots 12, projectinglateral shoulders 28 a are formed at the ends of the bars. Theguide bars 28 may be connected in pairs by transverse connectingelements 28 b to improve the stability of the bars in operation. - As shown in FIG. 12, each
tensioning element 29 comprises two ormore sections 31 which are joined together and to thebase 27 and to thebar 28 by means offlexible hinge regions 30 that render the tensioning element resiliently compressible in a longitudinal direction. As well as conferring on the tensioning element the resilient properties necessary to keep the filter loop taut when the spinning machine is in operation, this configuration makes the operation to insert and remove the filter loop particularly easy and convenient; the operator has to press thebar 28 towards thetube 11 with one hand whilst fitting or removing the filter loop with the other hand. - As can be seen in FIG. 12, three
support feet 32 extend from thearcuate base 27 of eachtensioning unit 26 for bearing on three distinct generatrices of thetube 11 in order to improve the stability of the unit when fitted. - Each
tensioning unit 26 is locked releasably on thetube 11 by means of a pair oftabs central manifold 15, one of thetabs 33 a (or 33 b) is fitted in one of theseats 22 of the manifold (FIG. 6) and theother tab 33 b (or 33 a) is fitted in acorresponding seat 34 defined between the outer surface of the tube and aconcave portion 35 of a stopper-like element 36 mounted on each of the ends of the tube. - In the preferred embodiment, each tensioning unit is moulded as a single piece of plastics material with good resilience characteristics.
- With reference now to FIGS.13 to 16, a stopper-
like element 36 has acylindrical portion 37 which is fitted in the end of thetube 11; a projection 38 is formed at a point on the outer surface of theportion 37 for coupling with the notch 14 of the tube 11 (visible in FIG. 2) in order to lock thestopper 36 in an angular position such that theseat 34 is disposed substantially on the side diametrally opposite that in which theslots 12 are present; thetensioning unit 26 is thus locked on thetube 11 on the side remote from that with the slots to ensure that the filter loops slide closely against the tube in the region of the slots. - At the end remote from that facing the tube, the
stopper element 36 has anappendage 39 which extends transversely and serves for the locking of thetube 11, at its opposite ends, on a pair of stationary elements (not shown) fixed to the spinning machine for conferring stability on the tube and on the subassembly as a whole. - The
appendage 39 is advantageously hollow in order to house an electrical connector (not shown) for connecting themetal tube 11 to a conductor element (not shown) to prevent the accumulation of electrostatic charges on thetube 11, in operation, so as not to promote the attraction and deposition of dust and textile fibres on the tube. - In order to assemble the unit of the present invention, first of all the
central manifold 15 is clamped onto the tube and then anend tab 33 a (or 33 b) disposed at the inner end of atensioning unit 26 is fitted in one of theseats 22 of the manifold and theunit 26 is then locked on the tube by fitting the plug-like element 36 on the end of the tube and fitting theend tab 33 b (or 33 a) disposed at its outer end into theseat 34 of the stopper-like element 36. Theguide bars 28 are pressed against thetube 11 and thefilter loops 23 are fitted around the tube and the respective guide bar one at a time. The same operations are repeated in order to lock the second tensioning unit on the opposite side and, finally, an end of a conductor element is connected to an electrical connector mounted in one of theappendages 39. In order to disassemble the unit, the sequence of steps set out above is performed in reverse.
