MASSACHUSETTS n TEXTILE FABRIC AND METHOD 'MANUFACTURE J Application led January 11,`1930.I Serial No. 420,246. i i

The present invention relatesI to crepe fab-l rics and methods of manufacture.

Filling crepe fabrics with which the present invention is particularly concerned as normally and hitherto produced in thc weaving industry require separate and individual filling ends of varying or opposite twist, each carried in an individual shuttle. The necessity for a plurality of shuttles to carry different filling ends involves the employment of more than one shuttle box with attendant complication andinevitable reduction in loom speed and production of finished cloth.

The principal purpose of the present invention is the production of crepe fabrics of any textile yarn commonly elnployed for the production of these fabrics by a new and novel method which is admirably adapted to employment with automatic bobbin or shuttle replenishing looms of convention al form with attendant high speed of production and low cost of manual supervision.

F or the accomplishment of this result -I propose to produce crepe fabrics having alternate filling ends of opposite twist laid in a single warp shed. Each two filling ends of opposite twist are wound upon a single carrying bobbin or quill in such a manner that the two ends may be exhausted `simultaneously and laid in the same shed at each pick.

In addition to the production of fabrics of the crepe type by a new and much simplified method, the laying of the oppositely twisted fillingl ends in a single shed produces a new and characteristic form of fabric differinf; desirably from crepe fabrics now or heretofore produced.

In the accompanying drawingl illustrating the preferred form of the invention,

Fig. l is a plan view of a woven crepe fabric embodying the features of the invention Fig. 2 is a transverse section of the fabric shown in Fig. l; and

Fig. 3 is a side view of a wound bobbin having the two filling ends wound thereon in parallel relation for simultaneous exhaustion.

Referring to the illustrated embodiment of the invention, it will be evident that two separate and non-intertwisted strands oflliing of opposite twistpden'oted by a and 6,are laid in asingle Shed of warp strands c. -This' `operation"is',repeated upon successive picks 'in' such va mannerthat each shed of vwarp 'strands` embraces two non-intertwisted`4 filling MASSACHUSETTS, A CORPORATION OF Strands of opposite twist,` aslindicated par# ticularly .in Figs- 1 and 2. The two filling strands a and b may be conveniently wound upon the same bobbin, as indicated in Fig. 3, in such a manner that exhaust-ion of the two filling ends from the bobbin takes place simultaneously at each pick of the shuttle. My new fabric, if so desired, may be produced in a less economical fashion by winding each filling end of opposite twist upon a separate bobbin, and thereafter laying the two filling ends independently in a single warp shed which is obviously kept open for two picks of the loom.

After completion of the fabric, it may be treated in the usual manner by boiling to impart the characteristic crinkled appearance of crepe fabrics. The fabric so produced is attractive in appearance with good draping qualities and feel, and effectively supplements y crepe fabrics now in existence.

Although the winding of the filling ends of opposite twist upon a single bobbin may. be readily accomplished upon the usual windln machinery without doubling, nevertheless i so desired the two ends may be doubled when wound for the purpose of producing special and characteristic effects.

It must be evident that this type of fabric produced in accordance lwith the foregoing description is capable of production in the or- I dinary and usual automatic looms of the weft-replenishing type asl each filling bobbm tution of bobbins or shuttles is required only upon exhaustion thereof in the usual manner. Furthermore, the simultaneous laymg Vis a duplicate of all other bobbins, and substiof the two lling ends at each pick of the shuttle greatly increases the speed of production of the finished cloth, resulting in substantially lower cost.

What is claimed is:

1. A method of weaving crepe fabric which consists in laying ina single warp shed separate and oppositely twisted filling ends,

the separate ends beingnon-intertwistedwith one another.

2. A method of Weaving crepe fabric which consists in simultaneously withdrawing from a singlebobbin two separate and ppo sitely twisted illing ends, the separate'ends being non-intertwisted with one another,y and laying the non-intertwisted endswithin a warpf shed. Y

3. A method of Weaving crepe fabric which consists in laying in successive Warp sheds a pair of separate and oppositely twisted filling ends at each pick, the separate ends being nonintertwisted with one another',

crepe fabric comprising a series of warp strands anda series of separate filling Vstrands ofy alternately vopposite lnvist,` eac shed of warpstrands embracing two `filling jstrands of opposite twist, the two filling strands in each warp shed' beingseparate from one anotherv and non-intertwisted.
