CHENILLE PRODUCTION MACHINES BACKGROUND OF THE INVENTION The present invention relates generally to the field of yarn producing apparatus, and more particularly, is directed to a novel machine for the production of chenille.

This invention is an improvement over the apparatus for production of chenille as disclosed in my copending patent application, Ser. No. 208,748, filed Dec. 16, 1971, now Pat. No. 3,777,464. Previously designed chenille production machines including the device disclosed in my said co-pending application developed tensions between the filler yarn and warp feeds and the finished chenille product, and these tensions frequently resulted in yarn breakage, a condition which resulted in considerable down time of the apparatus. Additionally, the prior art machines could not be readily stopped and started without damage to the finished chenille product either by yarn breaking or by an initial insufficient yarn filling in the finished product due to tension between the bobbin and the cutter. In normal quality control procedures, the finished chenille product had to be reworked, the damaged length of material cut out, the yarn retied, all of which was quite time consuming. Additionally, the finished yarn bobbins and the flyer of the previously available machines were all directly driven by a single motor acting through a single shaft. Inasmuch as the flyer is fabricated of heavy metallic construction, the momentum forces built up by rotation of the flyer caused a speed differential between the flyer and the bobbins wherein the flyer was slower to stop and slower to reach operating speed, thereby causing yarn tension between the flyer and the bobbins.

Additionally, the prior art type of chenille production machines suffered from other maintenance problems in the cutter blade area. The prior art cutter blades were fixed in position and accordingly, could not be readily adjusted as to height when conditions demanded. Additionally, the prior art cutter blades reciprocated within fixed bearings or bushings which had a tendency to wear after a period of operations, thereby causing the cutter blade to readily work out of alignment.

Further, in view of the rotary action of the prior art filler yarn spools, the speed of production was definitely limited. Yarn breakage would always result when the speed of operation exceeded a predetermined rate.

SUMMARY OF THE INVENTION The present invention relates to an improved apparatus for the formation of chenille yarn and is particularly directed to an aparatus which is capable of producing chenille yarn at greatly increased speed and with greatly improved efficiency.

The present invention includes a flyer which carries a plurality of spindles in upright orientation to receive yarn spools thereon. The spools are held in stationary relationship upon the flyer and it is the flyer and it is the flyer itself which rotates about the warp threads during the chenille formation process. The filler yarns either feed upwardly through yarn tensioning pigtails and then downwardly through the flyer floor for wrapping about the inside and outside warp threads or optionially, feed downwardly through internal bores which are provided in the spindles themselves.

The outside warp threads are synchronized for operation with the inside warp threads by turning about the lower band idlers simultaneously with the steel bands themselves. All of the filler yarns, the warp threads and the finished chenille product are continuously monitored by electric stop motion devices which are wired to automaticaly stop the machine operation upon detection of any yarn breakage.

The operation of the flyer and the finished yarn bob bins are controlled by separate motors which function through a single switch to synchronize action. The bobbin motor is provided with a reversing switch to permit either clockwise or counter-clockwise rotation of the bobbins depending upon whether the warp yarn cones are supplied with either an S or Z twist. By functioning the finished yarn bobbins and the flyer by means of separate motors, undersirable finished yarn tension between the bobbins and the cutter blade can be avoided to thereby minimize chances of yarn breaking during the manufacturing process or upon startup and to prevent unfilled spaces in the event the yarn did not completely break.

The machine is further improved in that all of the warp thread cones are now positioned in recessed boxes located in the upper portions of the machine. In

this manner, the turbulence created by the rapid rotation of the flyer can in no way affect the feeding of the warp threads to the machine by creating tangles, breakages, etc. Further, by providing two similar chenille production machines in side by side juxtaposition and by employing the recessed cone boxes, the apparatus can now accommodate twelve cones rather than the eight cones which were available in previous designs. This is an important improvement because in some types of chenille yarn, it is necessary to have three warp threads both inside and outside which could therefore necessitate twelve positions of threads in the side by side machines.

Warp threads guides and filler yarn pigtails are provided which are pivotal with respect to the aparatus itself. Accordingly, it is a simple matter to pivot the guides and pigtails outwardly to replace the warp thread cones and filler thread spools whenever desired. Each of the warp thread guide arms and the filler thread pigtails are provided with three or more yarn guide holes which are ceramic lined to provide combined yarn guide and yarn tensioning facilites.

The cutter blade of the present invention is greatly improved over previously employed blades in that the present mechanism includes pressure bars with set screws to allow vertical adjustment of the blade to any desired vertical position from the front of the apparatus without taking apart the entire apparatus. The blade holding bars are affixed to a hardened steel shaft which connects to the eccentric for reciprocating action. The shaft is reciprocal within a special bearing of the selfaligning type so that the blade, in conjunction with the special bearing will be self-aligning under all conditions of operation.

A vacuum air system has been provided and is equipped with two strategically placed air intakes, namely, one directly under the cutting blade to keep the cutting area clean and a second, in the form of which is an elongate inlet slot, positions on the spindle shelf to clean any material which may have dropped either from the cutting blade or which may have been produced by the ballooning action of the finished chenille yarn against the cleaning grid surrounding the finished yarn spindle.

It is therefore an object of the present invention to provide an improved apparatus for the production of chenille of the type set forth.

It is another object of the present invention to provide a novel apparatus for the production of chenille which is capable of increased rotative speed and increased productivity without loss of quality.

It is another object of the present invention to provide an improved apparatus for the production of chenille wherein the filler yarn spools position upon the flyer and wherein the finished yarn spools haave no rotative motionrelative to the flyer.

It is another object of the present invention to provide a novel improved apparatus for the production of chenille which includes means to synchronize the feed ing of the outside warp threads and the inside warp threads.

It is another object of the present invention to provide an improved apparatus for the production of chenille which incorporates a first motor for rotation of the flyer, a second motor for rotation of the finished yarn bobbins and means to operate the motors simultaneously.

It is another object of the present invention to provide a novel apparatus for the production of chenille which incorporates stop motion means to continuously monitor the filler yarn threads, the warp threads and the finished chenille product for breakages.

It is another object of the present invention to providea novel, improved apparatus for the production of chenille wherein the finished yarn bobbin is functioned by means of a separate motor and wherein the motor may be reversed to opeate the bobbin in either a clockwise or counter-clockwise direction.

It 'is another object of the present invention to provide an improved, novel apparatus for the production of chenille which includes means to vertically adjust the position of the cutting knife from the front of the apparatus.

It is another object of the present invention to provide a novel, improved apparatus for the production of chenile which incorporates knife shaft bearings of the selfaligning type.

DESCRIPTION OF THE PREFERRED EMBODIMENTS OF THE INVENTION Although specific terms are used in the following description for the sake of clarity, these terms are intended to refer only to the particular structure of my invention selected for illustration in the drawings, and are not intended to define or limit the scope of the invention.

Referring now to the drawings, I show in FIGS. 1 and 2 a chenille production'machine 10 including generally a frame 12 which is comprised of suitable angle iron construction to securely and operationally mount the operating components of the device. A first electric motor 14 is mounted upon the frame 12 in well known manner to rotate a vertical drive shaft 16 through a speed adjusting cone system 18 by employing an endless belt 20. The drive shaft 16 rotates the steel band drive shaft 22 in conventional manner, by means of a second speed adjusting cone system 24 and a second endless belt 26. Preferably, the steel band drive shaft is exteriorly threaded to form a worm gear 28 which cooperates with the band driving pulley gears 30 (only one of which is illustrated in FIG. 2) to rotate the right and left

band driving pulleys

32, 34 through the respective band

pulley gear shafts

36, 38. a

As best seen in FIG. 2, the bottom terminus of the band drive shaft 22 is fitted with a third speed adjusting cone system 40 which serves to rotate the flyer 44 by means of the interconnecting third endless belt 42. Similarly, the bottom end of the vertical drive shaft 16 is provided with a drive pulley 46 which is positioned to rotate the fouth endless belt 48 in a horizontal plane[ The fourth endless belt rotates the cutter blade operating pulley 50 which in turn reciprocates the cutter blade 52 in the manner hereinafter more fully set forth. It is thus seen that a unitary motor 14 simultaneously functions the flyer 44, the band drive pulleys 32, 34 and the cutter blade 52. The

endless steel bands

54, 56 respectively rotate around the band drive pulleys 32, 34 and the cooperating lower band idler pulleys 58, 60 in conventional manner to carry the inside warp threads and the wrapped filler threads to the cutter blade 52.

A second electric motor 62 conventionally mounts upon the frame 12 and functions a second vertical drive shaft 64 through a fourth speed adjusting cone system 66 by utilizing a fifth endless belt 68. The drive shaft 64 powers the finished

yarn bobbin spindles

70, 72 by employing at least one bottom endless belt 74 and the interconnecting belt 76. A main switch 78 mounts upon the frame 12 and conventionally is wired to both the first and second

electric motors

14, 62 to simultaneously start and stop the motors. in this manner, the machine operates as a unit and has no tendency to build up tensions or stresses between the warp yarns and filler yarns and the finished chenille product.

Referring now to FIGS. 1 and 2, the warp thread cones 82 are repectively positioned within recessed right and left

boxes

84, 86 in a manner to substantially reduce the effects of air turbulence created by the rapid rotation of the flyer 44 upon the smooth feed of the warp threads. The

inside warp threads

88, 90 feed from the upper warp thread cones 82 about the respective right and left inside warp thread

stop motion devices

92, 94 to the top 97 of the hollow flyer spindle. The

outside warp thread

96, 98 feed from the lower warp thread cones about the respective right and left outside warp thread

stop motion devices

100, 102 to the respective steel band idler pulleys 58, 60. In this manner, all of the warp threads are continuously monitored for breakage during all periods of machine operation.

Still referring to FIG. 1, I show a reversing switch 80 mounted upon the frame and conventionally wired into the control circuit (not shown) of the second electric motor 62. In order to understand the purpose of the reversing switch 80, it will be appreciated that the warp thread yarn may be delivered in cones 82 from the supplier with either an s twist or a z twist, which means the threads may be twisted either to the right or to the left hand. If the finished

yarn bobbin spindles

70, 72 were rotated in the same direction as the twist on the warp thread, this could double or even triple the twist in the finished yarn to thereby build up great stresses. By employing the reversing switch 80, the second motor 62 may be operated to function in either a clockwise or counter-clockwise direction to accordingly control the direction of rotation of the finished yarn bobbins.

The separate motor and pulley system to control the flyer rotations and the separate system to control the finished yarn spindle rotation is important in producing uniformly satisfactory finished chenille yarn without breakages, unfilled areas and similar defects. Prior art machines functioned with one motor and one shaft in a manner whereby the yarn was continuously under tension between the bobbin and the cutter blade. Quite often, the increase in tension at start up would result in breakages or unfilled areas. In the present arrangement, however, it will be noted that the flyer 44 is heavier than the

finished yarn spindles

70, 72 and therefore, due to the build up of centrifugal forces, will take longer to stop than the spindles, thereby relieving yarn tensions. The bobbin spindles will stop faster to completely relax the tension in the finished yarn between the bobbin and the cutter blade 52. In starting up, the

motors

14, 62 will be simultaneously energized by means of the switch 78 and the bobbin spindles will rotate to start to develop tension between the bobbin and the cutter blade. By the time tension is developed by the bobbin rotation, new yarn will be fed from the flyer to thereby continue the finished product without interruption or damage.

The

outside warp thread

96, 98 feed from the lower

stop motion devices

100, 102 to the steel band idler pulleys 58, 60. The idler pulleys 58, 60 are specially peripherally grooved at 104 (FIGS. 2 and 14) to provide a loop to receive the outside warp threads. It will be noted from FIGS. 1 and 13 that the inside warp threads 88, feed down through the central portion of the flyer spindle 106 and these threads move simultaneously with the

steel bands

54, 56. The

bands

54, 56 encircle the idler pulleys 58, 60 as do the

outside warp threads

96, 98. Accordingly, the

inside warp threads

88, 90, the

outside warp threads

96, 98 and the

steel bands

54, 56 will all move in unison at uniform speeds so that no unbalance or unequal feeding can occur between the inside warp threads and the outside warp threads.

Referring now to FIGS. 3 and 4, I show a novel flyer 44 which is attached to the hollow spindle 106 and is rotated thereby. There are no upper hearings or upper pulleys employed in the flyer assembly construction, thereby permitting unrestricted access from the top for filler yarn spool insertion and removal. The flyer floor 108 mounts a plurality of vertical, hollow studs 110 to support a plurality of filler yarn spools 112 thereon. It will be noted that the spools stationarily position upon the flyer 44, that is, the spools 112 have no motion relative to the flyer. Each stud 112 is preferably fabricated of steel or aluminum, is approximately seven inches high and approximately five-eights inches in diameter. Each stud is provided with a longitudinally extending axial bore 114 which communicates with a hole 116 which is provided in the flyer floor 108. The filler yarn threads 118 feed from the respective filler yarn spools 112 downwardly through an axial bore 114 of a hollow stud 110 and thence through the bottom opening 116. The threads 118 then feed horizontally inwardly through the inward openings 120 which are provided in the lower flyer vertical wall 112 toward the hollow spindle 106.

Prior to feeding into the interior holes at the flyer spindle 106, each of the filler yarn threads 118 is directed through a multiple stop motion device 126 which functions to continuously monitor all of the filler yarn threads for breakage during all periods of machine operation. If desired, all of the stationary studs 110 may be provided with outwardly projecting springs (not shown) to respectively bias 'against the core of the filler yarn spools to keep each spool 112 in stationary arrangement on its associated stud 110 and to securely hold the spool on the flyer 44. Inasmuch as the spools 112 do not rotate themselves, there are no centifugal forces generated which might tend to break the yarns, no matter how weak the yarn may actually be. Because of this novel method of filler yarn takeoff without spool rotation, any type of yarn, no matter how wweak, can be used without fear of breakage. This yarn takeoff arrangement additionally permits increased speed of operation. Tests have proven that speeds as great as sixty percent over speeds formerly attainable are now possible, thereby greatly increasing the productivity of a given chenille production machine.

As best seen in FIGS. 4, 10, 11, 12, the multiple stop motion device 126 is provided with a longitudinally extending internal bore 128 of size to overfit and tightly secure upon the outer periphery of the flyer spindle stud 7 106. Thus, as the flyer and spindle rotate, the multiple stop motion device 126 also is rotated. Electrical contact between the stop motion device 126 and the machine electricalcontrol circuit (not shown) is preferably accomplished by employing slip rings 130 whereby continuous rotary electrical contact can be maintained. In one embodiment of the device, a plurality of fixed yarn guides 132 are provided about the outer periphery 134 and each is provided with a fixed guide loop 136 toreceive a filler yarn thread therethrough. A cooperating spring biased, pivotal guide arm 138 having a corresponding guide loop 140 is associated with each fixed guide 132. Thus, when a filler yarn thread is unbroken, it will feed through the

respective guide loops

136, 140 to thereby keep the pivotal arm in vertical position against the bais of its spring. Should the filler yarn thread break, the pivotal arm 138 will swing to the inclined position illustrated in FIG. 10. In this position, a micro switch (not shown) will be activated to shut down the machine circuit.

FIG. 7, 1 show one embodiment ofa warp thread

stop motion device

92, 96,, 100, 102 which preferably includes a body 142 suitable for connecting to the frame 12, a micro switch 144, a yarn tensioning device 146, fixed yarn guide loop 148, a spring biased, pivotal yarn guide loop 150 and the pivotal guide arm 152. Should a warp thread break, the guide arm 152 will swing its guide loop 150 out of alignment with the fixed loop 148 to thereby activate the micro switch 144.

Referring now to FIGS. 8 and 9, the cutter blade assembly 154 is set forth which includes a bearing body 156 which is mounted in stationary arrangement upon the machine frame 12. The cutter blade pulley 50 rotates an eccentric 158 to conventionally reciprocate the cutter blade shaft 160. A self-aligning bearing 162 is employed to permit the cutter blade 52 to be automatically self aligning under all conditions of opera tion. The shaft 160 terminates forwardly in a pair of vertically positioned, horizontally spaced pressure bars 164, 166 which are interconnected by a plurality of set screws 168 which serve to permit easy vertical adjustment of the blade 52 from the front of the machine without the need to disassemble any part ofthe apparatus.

A modified type of flyer 170 is shown in FIGS. 5, 6 wherein the filler yarn spools 112 stationarily mount upon the flyer floor 172 by positioning upon a solid 174. A yarn take off guide 176 of generally V- shaped configuration is pivotally positioned above each spool 112 by a spring biased vertical support 178. Each guide is pivotal about its support 178 from a yarn feeding position 180 as illustrated in full lines to a spool changing position 182 as indicated in broken lines. The filler yarn threads feed upwardly and feed through the ceramic lined holes 184 provided in the take off guides 176. Preferably, the threads feed alternately upwardly and downwardly through the holes 184 for tensioning purposes.

Again referring to FIG. 2, a third electrical motor 186 powers a gear box pinion 188 which functions with the rack 190 to alternately raise and lower the finished yarn bobbin platform 192 to facilitate even winding of the finished chenille yarn 194 on the finished yarn bobbin 196. a ballon ring 198 cleans the finished yarn in well known manner as the yarn is wound on the bobbin 196.

The air system of the present invention may best be observed by referring to FIGS. 1 and 2. A suction fan 200 mounts upon the frame 12 in conventional manner and may be of the multi-vane type capable of developing the required static pressures for satisfactory lint cleaning operation. The fan 200 draws a portion of its suction from an air inlet 202 which is positioned directly beneath the cutter blade 52 by means of the interconnecting, flexible tube 204. The fan 200 draws the remaining portion of its suction from an elongate inlet slot 206 which positions on top the finished yarn bobbin platform 192 intermediate the finished yarn spindles to clean up any loose material which may have dropped either from the cutting blade 52 or which may have been produced by the ballooning action of the finished yarn 194 against the ballon rings 198. Flexible tubing 208 which preferably is similar to the tubing 204 interconnects the suction of the fan 200 with the inlet slot 206 in conventional Although l have described the present invention with reference to the particular embodiments therein set forth, it is understood that the present disclosure has been made only by way of example and that numerous changes in the details of construction may be resorted to without departing from the spirit and scope of the invention. Thus the scope of the invention should not be limited by the foregoing specification, but rather only by the scope of the claims appended hereto.
