No. 221,065 7 Claims priority, application Australia, Sept. 7, 1961, V 8,969/ 61 13 Claims. (Cl. 139-118) This invention relates to fringes used for decorative purposes on clothing, towels, curtains, blinds, furniture or the like and comprising a band of fabric having a plurality of free lengths of thread or yarn projecting from and attached to one longitudinal edge of the band. At present fringes of this type are produced by a knitting or weaving operation in known machines set up in a special but known manner. It is common practice to use in conjunction with a fringe a tape which is attached at one edge, by sewing, to the edge of the fringe band from which the threads or yarns project.

The fringe band and the attached tape form what is known in the trade as a pocket into which is inserted the marginal portionof the piece of material or fabric f to which the fringe is to be attached by sewing.

At present the tape is produced in a separate operato the fringe. Accordingly the costs of production of a complete fringe and tape assembly is comparatively expensive.

it is the principal object of the present invention to provide a fringe having a tape as an integral part thereof.

It is a further object of the present invention to provide a method of producing an integral fringe and tape in one operation.

The final object of the invention is to provide a machine to producethe integral fringe and tape in accordance with the above method, which machine is simple in constmction and has a high output rate.

With the above stated principal object in view there is provided according to the present invention a compo site decorative fringe comprising a band portion composed of thread, a free thread portion, and a tape portion, said free-threaded portion being comprised of a plurality of free lengths of thread attached to and projecting from one longitudinal edge of said band portion, said tape portion being composed of thread and being secured to said band portion adjacent said longitudinal edge by the interlocking-of respective threads of which said band portion and'tape portion are composed.

Conveniently the band and the tape are produced simultaneously by weaving operations and the weft threads of the tape portion are looped around complementary weft threads of the band portion. i i

With the above stated further object in view there is provided according to the present invention a method of producing in a single machine a composite decorative fringe having a band portion, a free thread portion and a tape portion, comprising weaving the band portion with transverse threads extending beyond one longitudinal edge to form the free thread portion of the fringe, simultaneously weaving the tape portion, and interlocking the threads of the tape portion with threads of the band portion along said longitudinal edge.

More specifically there is provided a method of producing a single machine, a composite decorative fringe have a band portion, a free thread portion, and a tape portion comprising setting up band and tape sheds in superimposed relation, weaving a continuous band weft thread through the band warp shed and extending said ice first weft thread a substantial distance beyond one edge of the band warp to form threads of the free thread portion, simultaneously weaving a continuous tape weft thread through the tape warp shed, and looping said tape weft thread at least once around the complementary band weft thread during a complete returning pass of the tape weft thread.

By weaving the fringe in accordance with this method the three portions of the fringe are produced simultaneously and are secured together by the weft of the tape portion being interlocked with the weft of the band portion.

With the above stated final object in view there is provided according to the present invention a weaving machine for making a composite decorative fringe having a band portion, a free thread portion and a tape portion, comprising means for supporting and subjecting superimposed band and tape warp sheds to an alternating weaving movement, means to pass a continuous band weft thread through the band warp shed so as to form a thread of the free thread portion on one side of said band warp shed, and means to pass a continuous tape weft thread through the tape warp shed, said tape weft thread passing means being arranged to loop the tape weft thread around the band weft thread once during each complete returning movement of the means to pass the tape weft thread.

Conveniently the band and tape weft threads are passed through the respective warp sheds by oscillating members, the path of the member carrying the tape weft threadbeing controlled by cam. means to cross the path of the member carrying the band weft thread. The timed relation of the movement of the two oscillating members being such that the member carrying the band weft thread passes twice between the tape weft thread and the member carrying it, while the members are in a crossed relation.

The invention will be more readily understood from the following descripiton of one practical arrangement t manufacturing of the fringe fabric.

of the fringe and the apparatus for manufacturing same as illustrated in the accompanying drawings.

In the drawingsr FIG. 1 is a magnified perspective View of a piece of the fringe fabric.

FIG. 2 is a perspective plan view of the apparatus for manufacturing the fringe fabric.

FIGS. 3, 4, 5 and 6 illustrate progressive stages in the FIG. 7 is a detailed view of the hook member.

Referring now to FIG. 1 the fringe fabric comprises a band portion 10 having. warp threads 12 and interweaved double passed weft threads 11. Each double passed thread 11 projects beyond the edge 13 of the band to form a twisted free thread. portion 14. The tape portion 15 has warp threads 16 and interweaved double passed weft threads 17 each of which is looped at 18 around the complementary double passed weft threads 11 of the band portion.

In use the marginal portion of a piece of. material is inserted between the integral band and tape which are then sewn to the material.

Referring now to FIG. 2 the machine for manufacturing the integral fringe and tape includes the conventional arrangement of healdsand reed, and other operating mechanism to support and actuate two superimposed warp sheds in the known manner.

The warp threads 16 of the tape warp shed are superimposed of the threads 12 of the band warp shed and each set are operated by separate healds so arranged that, in each of the two alternate operating positions of the healds during the weaving operation, the top threads of 1 theband warp shed are located in substantially the same horizontal plane as the bottom threads of the tape warp 2.4 is-attached to the pin 23 and coupled through the adjustable length link 25 to the lay 21 of the Weaving machine to effect an oscillatory angular movement of the pin 23. Attached tothe pin 23 are twohorizontal weft I inserting ar'ms26' and 27 respectively.

The arm 26 has fixed thereto the arcuate shaped band I weft tube '39 through which the band weft thread 11 passes. The arm 27 carries two bearing blocks 32 in which 'the'tape weft tube 31 is journalled for angular movement "about a horizontal'axis. The tape weft thread 17 passes through the tape weft tube 31. g p

The tape'weft'tube'31 carries an arm 29 which is con- 'nected by'the Spring 33 to the weft arm 27. A suitable "-stop is provided so that 'the springs 33 normally maintains the leading end 31a of the tapeweft tube'at the 'correct relative height to pass freely through the shed of the tape-warp. The tape weft tube 31, rearwardly of the leading'end 31a is inclined upwardly so that after said leading endhas passed through the shed of the tape warp i the inclined portion will engage the upper threads of the tape 'warp. The continued movement of the tube will deflect the leading end 31a downwardly by rotation of the tube 3l'relative tothe arm 27 against the action of the spring 33. The purpose of the downward deflect of the leading edge of the tube 31 will be explained later in the specification, and it is tobe understood that it can be achieved by'other means than engagement with the tape warp threads, such as by a suitably contoured cam. Theinovement of the inserting arms 26 and'27 is timed inrelation to the alternatin'g of the warp shed so that the weft tubes 30 and 31'ma'kes one complete movement in each direction through the'warpsheds between each "change of position of the warp sheds.

Mounted on the breast'beam 21 on the side of the warp sheds opposite the pin 23 is a member 36 having a hooked end 37. The hooked end 37 is disposed relative to the path of travel of the band weft tube SG'to be engaged by the band weft thread 11 as the tube nears the end of the movement inthe inserting direction and hold the thread as'the tube movesback or is withdrawn in the opposite direction. The hooked end 37 of the'member T 36 is'spac ed from the edge of-the warp sheds a distance T the fringe.

proportional to the required length of the free threads of The forward face 39 (FIG. 6) of the hooked'end is inclined upwardlyand rearwardly so that when the band weft thread engages s'aid fac the continued movement of the bandwefttub'eBtl will cause the thread toslide up "the face 39 and'drop into the hook.

The separate weft threads are fed by a suitable known mechanism including aftensioning device, from reels to the respective weft tubes.

In operation thewarp. sheds of the band and the tape portions are setup in the previously described superimposed relation, Each set' of warp threads are divided 'in' the usual manner so that in'each alternate operating position the lower threads of the tape warp are in sub- "stantially' the same horizontal plane as the upper threads of the'band warp.

At the commencement of the oscillatory movement i'the

tyvo weft tubes

30 and 31 move forwardly through I the respective divided warps, the tape Weft tube 31 being slightly in advance of the band weft tube 30 as can be seen in FIG. 3.

.After. the leading end 31a of" the tape weft tube has passed completely through the tape warp the inclined porn tion of the tape weft tube 31 engages the upper portion of the tape warp and its continued forward movement results in a downward tilting of the leading end 31a across the plane of travel of the band weft tube 30.

As the forward movement of both tubes continues the band weft tube passes through the loop formed by the downwardly tilted tape weft tube and the tape weft thread as shown in FIG. 4. 7

As the forward movements of the two weft tubes continue, the band weft thread engages the inclined face 39 of the hooked member 36 and then slides up and over the top of the inclined facetobe located in the hook as shown in'FIG. 4. p a

I The two weft tubes have now reached the end of their forward movements through the respective warps and now commence their reverse or returning movement through the warps to their initial location. As the band weft tube; returns the band weft thread passes around the hook 337 so that the returning portion of the band weft thread extends across the inclined face 39 of' the hook.

During the returning movement of the two weft tubes the band weft tube and thread again pass through-the loop formed by the tape weft tube and thread, and the camming action of the upper set of tape warp threads engaging the tape weft tube results in an upward movement of said tube.

The band weft thread: remains in engagement with the hook 37 during the returning movement of the band weft tube andthus an elongated loop is formed extending laterally from oneedge of the band warp. Furthermore the tape weft thread'has beenpassed around the 'two lengths of band weft thread forming the laterally extending elongated loop and thus the band and tape are positively inter locked.

-After the two weft tubes have completed the double pass through the respective warpsand returned to their initial position the reeds move forward in the conventional manner to compact thenewly inserted weft threads in the respective warps. This movement of the reeds also "effects release of the band Weft thread from the hook by engaging andap plying pressure tothe returning band weft threadto cause it to slide up and off the inclined face 39 of the hook.

The band 'weft thread usually consists of a highly twisted or live yarn so that uponiheing released from the hook the threads forming the laterally extending elongated loop will automatic'allytwist' aroundeach other to form the conventional twisted free fringe thread. a

Apart from the twisting together of the threads'of the loop, the live yarn will tend to fly or recoilback towards j thewarp sheds if released suddenly from the book 37. -Accordingly the buffer 40 is, provided at a location between the Warp sheds and the hook; and the threads of the loop are held against this buffer by the reeds while the loop is released from the hook.

'The above described cycle of operation produces one complete free fringe thread and the associated section of the integral band and tape and' the cycle is then re.

i the length of the machine.
