Definitions

  • First and second spaced apart conveyors each of which may be an endless chain, carry a plurality of thread clamping means.
  • a guide means moves between the two conveyors, and guides filling threads drawn from relatively stationary supplies.
  • a plurality of first conveyor clamping means are operated simultaneously as the guide means crosses them, to clamp the filling thread ends.
  • Filling threads are drawn from the first conveyor to the second as the guide means moves, and a plurality of second conveyor clamping means are operated simultaneously as the guide means crosses them, to clamp the filling threads. Thereafter, the filling threads are cut between the second conveyor and the guide means.
  • the conveyors then move the filling threads to the knitting instrumentalities of the knitting machine.
  • Knitted fabrics ofier desirable draping qualities are not as dimensionally stable as woven fabrics. It has been found that the dimensional stability of knitted fabrics can be enhanced without sacrificing their draping ability, by incorporating filling threads into them. The problem presented is how to feed such filling threads to a knitting machine during the knitting operation, so that'the filling threads become a permanent part of the knit fabric. I
  • the filling thread is then clamped by a clamp on the second conveyor, and thereafter the filling thread is served from the remainder of the thread supply on the cone.
  • Each individual filling thread extending between the first and second conveyor is then delivered by those conveyors to the knitting instrumentalitiesof the machine.
  • the apparatus just described involves a number of serious disadvantages, First, since the supply cones'of filling thread move continuously along the third conveyor, the tension of the thread being drawn from any of the cones cannot be adjusted without stopping the knitting machine. Secondly, when one of the supply cones becomes exhausted, the entire knitting machine must be stopped to permit replacement with a fresh cone. Also, a source of suction, and attendant connec-.

  • the apparatus chosen to illustrate the present inven-- tion is located behind and in part beneath a substan- 'tially conventional warp knitting machine.
  • the knitting instrumentalities of the machine are indicated generally at 10 in FIG. 2, and are located in there'gion ll of FIG. 1, but are not shown in FIG. 1.
  • Individual filling threads 12, extending between a first conveyor 13 (FIGS. 1- and 2) and a second conveyor 14, are moved to the knitting instrumentalities, 10.
  • the knitting cycle of the machine is identical to a conventional knittingcycle, exceptthat a filling thread 12 is placed behind the knitting needles at some point during each knitting cycle.
  • the filling threads are incorporated in the fabric on top of the row of loops produced during the immediately preceding cycle and beneath the threads which will formthe-next row of loops.
  • the filling threads are not involved in the actual knitting operation, i.e they are not engaged by the hooked upper ends of the knitting needles,.nor do they pass through the usual guide eyelets through which the threads extending from the warp beams pass.
  • each conveyor 13 and 14 is an endless chain, having a top and bottom run, trained about sprocket wheels 17 mounted for rotation on horizontal shafts 18.
  • Each shaft 18 is rotated by a suitable transmission (not shown) connected to the main drive shaft of the knitting machine.
  • the conveyors are spaced apart a distance slightly exceeding the width of the needle bed of the knitting machine, i.e., the width of the knitted fabric produced by the machine.
  • Each frame carby frames 21.
  • a fixed channel-shaped support 26 may be provided to support the top and bottom runs of each chain.
  • One stub shaft 22 of each conveyor chain is connected by a suitable transmission (not shown) to the main drive shaft of the machine so as to move all the chains 24 and in such a way that the lower run of each chain moves from the right toward the left in FIG.-
  • carriage 30 moves downwardly around the opposite sprocket wheels 23 and its direction of movement is again reversed.
  • carriage 30 is furnished with a plurality of thread guide members or eyelets 34, and the same number of eyelets (FIG. 4) is provided along its from lower edge.
  • the number of eyelets 34' or 35 is equal to the number of individual filling threads 12 which are to be applied simultaneously to the con-' veyors 13 and 14 during each pass of carriage 30 from conveyor 13 to conveyor 14.
  • any number offilling threads can be applied, but forthe sake of illustration in the present example it will be assumed that 72 filling threads are simultaneously applied to the conveyors.
  • carriage 30 Adjacent to its rear lower edge, carriage 30 carries a horizontal bracket 36 (FIGS. 1, 2, 4, and 5) slidable laterally with respect to carriage 30, i.e., slidablein a direction parallel to thelength of conveyors 13 and 14.
  • a horizontal projection 37 on carriage 30, having a dovetail cross-sectional shape, is slidably. accommodated within a dovetail recess in bracket 36, to effect the sliding connection between bracket 36 and carriage 30.
  • Bracket 36 has an upstanding cam follower 38 at one end and an upstanding extension 39 at the other.
  • a tension spring 40 (FIG. 2), extending between extension 39 and carriage 30 urges bracket 36 toward the right in FIG. 2, and maintains follower 38 against a cam bar 41 carried by one of the frames 21.
  • a horizontally projecting cam 42 (FIGS. 1 and 5) is mounted on cam bar -41 and extends the entire distance between conveyors l3 and 14.
  • Cam 42 cooperates with follower 38 to shift bracket 36 laterally against the force of spring Bracket 36 carries 72 thread holding means or clamps, the number 72 being illustrative as explained above.
  • Each thread clamp includes a stem 46 extending rounds each stem 46 between the upper face of bracket 36 and the lower face of follower 48 and urges clamping head 47 against the bottom face of bracket 36, i.e., thread clamping condition.
  • the thread clamps are in this condition except when the ends of follower 48 are beneath the lowest portion 51 (FIGS. 4 and 5) of cam bars 41 and 49. In this latter case, follower 48 pushes stems 46 downwardly against the force of springs and moves clamping heads 47 away from the bottom face of bracket 36, so that threads '12 can move with respect to the clamps.
  • a long arm 54 (FIGS. 1 and 4) swingable about a vertical pivot 55.
  • the portion of arm 54 above carriage 30 is furnished with, in this example, 72 eyelets 56, and near its pivot 55, arm 54 is furnished with another set of 72 eyelets 57.
  • Each eyelet 56 and 57 guides a thread 12 from one of 72 thread supplies 58, which may be in the form of the usual wound cones to one of the eyelets 34 on carriage 30. From eyelet 34, each thread is guided through an eyelet 35, and then to one of the clamps including head 47.
  • arm 54 Through a suitable transmission (not shown) connected to the main shaft of the machine, arm 54 is swung back and forth through an are having a long enough radius so that its free endv carrying eyelets 56 remains close, and substantially parallel, to carriage 30. Arm 54 thereby serves to prevent any slack in threads 12 from becoming entangled in the mechanism which moves carriage 30.
  • Conveyors l3 and 14 may be identical, and-hence only one will be described in detail.
  • each conveyor is a chain comprising relatively large rigid links 61 (FIGS. 3, 6, and 7) joined to adjacent like links by short flexible chains 62 and made of much smaller links.
  • This construction makes each conveyor expansible and compressible along its length.
  • each two successive links 61 are spaced apart-to a maximum'extent and the chain 62 between them is substantially straight.
  • This condition is illustrated in the bottom run .in FIG. 3.
  • each two successive links touch each other, and the chain 62 between-them hangs down in a loop, as shown at the right end in FIG. 3, and the V left end in FIG. 7.
  • Each link 61 has lateral flanges 63 slidably arranged in support channels 64 (FIGS. 1, 2, and 6; for clarity channel 64 has been omitted from FIG. 3) mounted on a stationary framework 65.
  • a thread clamp carried by each link 61 comprises a cylindrical anvil 66 fixed'to the link, a stem 67 extending slidably through an aperture in the anvil and link, and a clamping head 68 fixed to the upper end of stem 67.
  • a follower 69 is fixed to surrounds stem 67 between follower 69 and the bottom face of link 61 .
  • Spring 70 normally holds clamping slidably through a vertical aperture in bracket 36, and
  • a single elongated cam follower 48 is located behind the rear face of carriage 30 and is secured to the upper ends of all the stems 46.
  • the extremities of follower 48 which extend beyond the sides of carriage 30, engage the under surfaces of cam bars 41 and 49, these two cam bars being identical except that they are secured to opposite frames 21 and only cam bar 41 carries horizontally projecting cam 42.
  • a compression spring 50 surthe lower end of stem 67, and a compression spring head 68 against anvil 66.
  • a thread clamp actuator Located beneath the upper run of each conveyor chain 13 and 14, in the region between the frames 21- (as viewed in FIG. 1), is a thread clamp actuator, seen best in FIGS. 6 and 7.
  • the actuator includes a member 73 having three vertical portions 74 slidable vertically through apertures in frame 65.
  • a horizontal portion 75 is arranged in vertical alignment with followers 69, and is of such length that it can simultaneously engage, in the present example, exactly 72 followers 69.
  • the end verticals 74 extend above horizontal 75 to form abut-- ments 71. Normally, member 73 is pulled down to the broken line position in FIG. 7. by tension springs 76, wherein member 73 does not engage followers 69.
  • a pair of solenoids 77 whose armatures are connected to member 73 serve, when energized, to lift member 73 to its full line position in FIG. 7, wherein portion 75 engages followers 69 of 72 clamps and thereby lifts the clamping heads 68 of those clamps away from anvils 66. Also, abutments 71 engage the end links 61 of the 72 links above horizontal 75 and temporarily stop the 72 links, although the remainder of the chain continues to move. When the solenoids 77 are deenergized, springs 70 again brings heads 68 into contact with anvils 66 and the 72 links are free to move again.
  • Frame 65 associated with conveyor 14 is provided with an additional solenoid 78, the armature of which carries a band saw 79 (FIGS. 1 and 6) which may move continuously.
  • a tension spring 80 normally holds the armature and saw 79 down, but when the solenoid 78 is energized the saw is moved upwardly into a position for cutting filling threads 12, as will be described below.
  • each chain conveyor 13 and 14 permits actuator 73 to temporarily halt 72 of the chain links, as mentioned above, without stopping the chain as a whole. Stopping of 72 links simultaneously is needed to permit opening of the clamps and to permit eyelets 35 and clamps 47 carried by carriage 30 to pass, in meshing relationship, between the chain clamps, the purpose of which will be described below.

  • Each sprocket wheel 17 and 83 may be constructed, as shown in FIG. 3A, of two spaced apart sprocket plates 85 and 86 joined by a hub 87. The spaces 88 between the sprocket teeth accommodate the lateral flanges 63 of links 61.
  • the pitch of the teeth of each sprocket wheel 17 is such that they accommodate links 61 in their maximum spaced apart condition.
  • the pitch of the teeth of each compressor sprocket wheel 83 is such that they accommodate links 61 in their maximum compressed condition, i.e., successive links 61 touching each other.
  • the diameter of sprocket wheel 83 is smaller than that of sprocket wheel 17, so that the former engages only the top run of its respective chain 13 or 14.
  • the periphery of sprocket wheel 83 isrotated, via a suitable transmission (not shown) connected to the main shaft of the knitting machine, at a speed slower than the speed of rotation of the periphery of sprocket wheel 17. It is this difference in speed which causes links 61 to move closer to each other as they travel from sprocket wheel 17 (in FIG. 3)

  • follower 38 has not yet engaged cam 42, and hence each carriage clamping head 47 is directly behind an eyelet 35 (FIG. 8a).
  • follower 48 has not yet engaged cam bars 41 and 49, and hence the end of each of 72 filling threads 12 is clamped between a carriage clamping head 47 and the bottom face of bracket 36 (FIG. 8a).
  • FIG. 9a illustrates carriage approaching conveyor 14, bracket 36 still being in its shifted position.
  • eyelet moves between two clamping heads 68d and 68e. 72 such heads are lifted off their respective anvils 66 by energization of solenoids 77 associated with conveyor 14.
