  • each winding head comprises a rotary winding guide mounted to be driven around a nonrotary support for the package with a relative axial traversing movement.
  • This movement has one component in the form of a relative reciprocating motion, of stroke considerably less than the length of package, common to all the winding heads, and a second in the form of a progressive uni-directional motion produced by mechanism which is independently adjustable at each winding head.
  • a tape can be led to each winding head in turn to start forming a package, and, although the reciprocating motion is common to all the packages, they can be at different stages of progressive formation. Each package may then be completed in the sequence at which they were started and each complete package doffed and-the next started before the next package in sequence is ready for doffing.
  • the length of the reciprocating stroke extends only over the tapered nose portion of the package, so that the tape is laid over this portion. It is therefore necessary to make the taper a gradual one, since otherwise, when unwinding, the tape is inclined to pull off in gulps, i.e. a number of successive coils, rather than be unwound coil by coil. This can be a cause of frequent stoppages. If a nose'of sufficient length and taper is formed to prevent this occurring, for a given length of package this appreciably restricts the diameter and weight of the package. In most cases, of course, it is desirable to get the effective maximum amount of material on a given length of package.
  • the nose it is possible to makev the nose shorter and yet prevent the tape pulling off in gulps if it is wound with a traverse extending over the effective length of the package rather than just the nose.
  • This can be achieved by using a different form of traverse mechanism in which, at the start, the traverse extends for the full length of the package, and it is then progressively reduced as the package is wound to form the taper at each end.
  • the ends of the package can have a taper of approximately 30 as compared with approximately lO as obtained with the method previously described, thus permitting the building of a larger diameter package for a given length, and hence a heavier package.
  • the angle of taper at the end of the package is controlled by the rate of reduction of the length of traverse and the present invention is based on the principle of increasing this rate of reduction during the period in which the packages are being doffed so that the portion of each package wound during this period (i.ei, the much shorter core portion already described) has a much smaller angle of taper, e.g., 8 In this way the sharp corner referred to above is eliminated and the resultant gradual taper presents a smooth surface over which the unwinding tape can slip quite easily without plucking.
  • Apparatus in accordance with the invention operat-' ing in this manner comprising a multi-head winding machine of the kind referred to above and intended for the winding of material delivered from a controlled speed source of supply has traverse mechanism common to at least a group of winding heads and includes mechanism for progressively reducing the length of traverse stroke during winding and a control for increasing the rate of reduction of stroke during the period of winding when completed packages are being doffed and fresh packages started.
  • This mechanism leads to the elimination of the sharp corner on the core portion of each package wound during the doffing period and thus facilitates unwinding in the manner already described.
  • a winding machine in accordance with the invention may also be used for the winding of yarn and other similar material.
  • the traverse mechanism is common to at least a group of winding heads and preferably a single mechanism serves for all the winding heads of the machine, the package supports being mounted on a common length or lengths of builder rail to which the traversing motion is applied by the traverse mechanism.
  • the traverse mechanism may conveniently comprise a lever arm which is rocked about its fulcrum under the control of a cam and which is connected to the builder rail or rails by way of a link including one or more lengths of chain or the like by means of which the reciprocating movement is transmitted and the mechanism for reducing the length of traverse stroke of the builder rail or rails serves to reduce the distance from the fulcrum of the lever arm of the point of connection to the link.
  • This mechanism may conveniently operate by. a standard amount for each stroke of the arm during the greater part of the winding process, the
  • this connection may be made by way of a connection block in the form of a nut mounted on a lead screw extending along the length of the arm so as to form part of the arm, the screw being turned step by step to produce the adjustment.
  • the screw may carry an indexing wheel capable of being turned through successive angular steps by means of a pawl operated by a reciprocating mechanism.
  • the reciprocating mechanism may comprise a pneumatic cylinder, the stroke of which may be adjustable, andvwhich is controlled either by a valve operated by rocking movement of the lever arm or by a second valve operated more rapidly by a member driven by gearing in the drive to the cam, the respective valve being selected by a change-over switch.
  • the pneumatic cylinder may operate the pawl once or twice for every stroke of the lever arm while during the doffing period the second valve may produce more rapid operation.
  • FIG. 1 is a view of traverse mechanism showing its parts in a position taken up just before the beginning of the doffing period;
  • FIG. 2 is an end view of a builder rail including a package support and a completed package
  • FIGS. 3 and 4 are views corresponding to FIGS. 1 and 2 but showing the parts after resetting at the end of the doffing period;
  • FIG. 5 is a perspective view of the traverse mechanism with the parts in the same position as in FIG. 3 and also showing part of the builder rail and a newly started package.
  • the multi-head winding machine shown in the drawings has a common builder rail 1 which extends for the length of the machine and is controlled by a single traverse mechanism indicated generally as 2. Although, as illustrated, the machine is single-sided, the traverse mechanism 2 can equally well control a double-sided machine having similar builder rails on both sides.
  • the builder rail 1 carries a number of non-rotary package supports 3, one of which is best seen in FIG. 4 and one only of which is shown in FIG. 5 carrying the initial stages of a package.
  • Each non-rotary support has a cooperating flyer 4, the two together constituting an individual winding head and the relative reciprocating motion between the two is produced by traversing movement of the builder rail 1. As best seen from FIG.
  • the material to be wound which will be assumed to be tape, is shown as 5 and passes via a let-off roller 6, over the shoulder of the flyer at 7 and via a guide roller 8 and a winding-on guide 9'to the surface of a package shown as 10.
  • the invention is primarily concerned with the traversing movement of the builder rail 1 which will now be described in more detail.
  • the builder rail 1 is mounted to reciprocate on vertical guides and is fitted with rollers 16 bearing against these guides. Although only a single guide 15 is shown in the drawings, the guides are, in fact, spaced at intervals along the length of the machine and the traversing movement of the rail 1 is controlled by a separate chain 17 passing over a roller 18 at each vertical guide 15.
  • the chain 17 is attached to a bar 20 which extends along the length of the machine and has a chain 17 attached to it at intervals.
  • the bar 20 in its turn is caused to reciprocate by means of a chain 24 forming part of a winch mechanism and wound up by a winch wheel 26.
  • the wheel 26 is mounted on a shaft 28, the rotary movement of which is produced by a second winch wheel 30 also secured to the shaft and controlled by a chain 31.
  • the chain'31 passes around a further winch wheel 34 mounted on a shaft 35 which carries a further wheel 36 controlled by a chain 38.
  • the chain 38 is connected in its turn to a link member 40 which is indirectly connected to a traverse arm 42 having a fulcrum 43 and caused to rock by a heart cam 45. The rocking movements of the arm 42 are thus transmitted to the builder rail 1 by way of a link which includes the successive lengths of chain 17, 24, 31, and 38 and also the link member 40.
  • the stroke of the traversing movement of the builder rail 1 is thus controlled by the distance from the fulcrum 43 of the point of connection of the link member 40 to the arm 42.
  • the arm 42 includes members 51 and 52 which are spanned by a lead screw 53.
  • This lead screw carries a nut member 54 which has transverse projections 55 capable of sliding in a slot 56 in a member 57 which is connected to the link member 40 at 58.
  • the combination of the parts 54, 55 and 57 together constitute a connection block by means of which the effective connection point of the link member 40 to the arm 42 can be adjusted in respect of its distance from the fulcrum 43.
  • the adjustment is effected by an indexing wheel 62 which is fixed to the end of the lead screw 53 and is turned step by step by means of a pawl 64 operated by a pneumatic cylinder 65.
  • a connection block constituted by the parts 54, 55 and 57 moves along the lead screw 53, the chain 38 together with the link member 40 turns about the edge of the winch wheel 36 as centre and rollers 76 on the part 57 run along an arcuate support 77 centred about the centre of the turning arc so that the tension applied to the chain 38 does not apply any loading to the lead screw 53, but applies the loading directly to the arm 42 by way of the rollers 76 and the supporting surface 77.
  • the pneumatic cylinder 65 is of adjustable stroke so that the amount by which the indexing wheel 62 is indexed for each stroke of the cylinder 65 can be adjusted as required.
  • the pneumatic supply to the cylinder 65 passes by way of a change-over valve 70, in one position of which the supply then passes via valves 71 and 72 to the cylinder 65.
  • the valves 71 and 72 have projecting triggers shown as 73 and 74 respectively which are operated by a small projection 75 at the left hand end of the lever arm 42.
  • valve 72 is operated and when it reaches the clockwise limit of its travel the valve 71 is operated, the wheel 62 being indexed by an amount dependent on the adjustment of the pneumatic cylinder 65 for each operation of these valves.
  • FIGS. 3 and 5 show the traversing mechanism immediately after it has been reset at the beginning of a set of packages and when the traverse stroke is required to be a maximum.
  • the connection point to the arm 42 is towards the left hand end of the arm so that the distance from'the fulcrum 43 is a maximum.
  • the wheel 62 is progressively indexed under the control of the valves 71 and 72 and the connection block comprising the parts 54, 55 and 57 is progressively moved to the right along the lead screw 53, thus progressively shortening the traverse stroke.
  • a light 80A is caused to flash by means of a switch 80 which is engaged by the part 57 as shown in FIG. 1.
  • the heart cam itself is driven from a motor driving pinion S8 and gearing 89, 90, 91, 92, 93 and 94. It is the wheel 92 in this train of gearing which drives the chain 85.
  • the rate of revolution of the wheel 92 is chosen so that the rate of indexing of the wheel 62 and hence the rate of reduction of the traverse stroke is considerably increased, e.g. by a factor of 4. As already described, this reduces the taper of the portion of each package which is being built at this stage. For the packages which have not yet been doffed, no advantage is obtained, but for the packages which have been doffed and new packages restarted,this achieves the important advantage already described. It will be understood that at this point the traverse stroke is close to its minimum value so that the initial core portion of each new package will be very short and once the traverse mechanism has been reset to its starting value, the subsequent layers of turns will be wound over the top of this short core portion as shown by the package illustrated in FIG. 5. It will be seen that although this package is of full length it has a localised central swelling which is constituted by the initial core portion.
  • the spindle S which runs up the center of the stationary package is driven near its base by a belt (not shown).
  • the top of the spindle is slotted to accommodate a correspondingly shaped portion of the flyer during normal running.
  • a brake is applied to the spindle, thus causing the drive belt to slip.
  • Suitable brakes for this purpose are disclosed in British Pats. No. 1,023,935, No. 1,281,806, and No. 1,187,829.
  • the flyer is then simply lifted off the spindle to permit the doffing of the full package and its replacement by an empty package support.
  • the brake is then disengaged from the spindle and normal drive resumed.
  • the flyer may be mounted on a spindle which is driven through a friction clutch capable of slipping, as described in US. Pat. No. 3,559,917.
  • the flyer can easily be stopped by hand, thus causing the clutch to slip while the package is doffed.
  • the traverse stroke continues to decrease and the member 57 next operates a further switch 95 which operates a further flashing light 95A to warn the operator that the doffing of the packages should soon be completed since their diameter has reached a size which will soon foul the flyers of the winding heads.
  • the pneumatic control is switched back to the two valves 71 and 72 by operation of the change-over valve 70, thus resetting the indexing of the wheel 62 to its original slower rate.
  • the operator turns the lead screw 53 by hand to bring the nut 54 back to its original position, i.e., to produce the full traverse stroke, as a result of which the short core portions which have been wound on the package supports are covered by a layer of turns extending for the full traverse length as already described.
  • each short core portion at the start of each new package is wound when the indexing action is under the control of the valve 82, that is to say at a high rate of reduction of the traverse stroke so as to give a small angle of taper which causes no difficulty during unwinding. This renders it possible to wind the larger packages associated with the type of traversing motion described but without their associated disadvantages.
  • each said winding head comprising a rotary guide, a non-rotary package support and means for driving said rotary guide around said support; traverse mechanism common to a plurality of winding heads to produce a relative axial traversing motion between each said rotary guide and said respective package support, said traverse mechanism including a lever arm mounted to rock about a fulcrum, means for progressively reducing the stroke of said traversing motion at either of two predetermined rates of reduction, and control means manually operable while said driving means is in operation to change the rate of reduction produced by said stroke reducing means from one of said predetermined rates to the other, whereby the higher of said predetermined rates may be applied during the period of winding when completed packages are being doffed and fresh packages started, said control means comprising a pressure-actuated cylinder connected to actuate said stroke-reducing means and to be actuated through a pneumatic circuit having two branches, a source
  • a winding machine as claimed in claim 1 in which said traversing mechanism comprises a length .of builder rail common to said package supports and through which said traversing motion is applied to said package supports.
  • a winding machine in which said traverse mechanism also comprises, cam means for rocking said lever arm about said fulcrum, and a link including one or more lengths of flexible connector, connecting a point on said lever arm to said builder rail, said means for reducing the length of said traverse stroke of said builder rail serving to reduce the distance between said fulcrum of said lever arm and the point of connection to said link.
  • said stroke reducing means including a lead screw extending along the length of said arm so as to form part of said arm, a connection block in the form of a nut mounted on said lead screw, said connection block serving to connect said link to said arm, an indexing wheel carried by said lead screw, a pawl for turning said indexing wheel through successive angular steps, and said cylinder connected to said pawl for operating said pawl.
