CAROLINA METHOD OF WEAVING TERRY FABRIC AND THE RESULTING IRODUGT Application filed March 23, 193 1, Serial No.524,727.

This invention relates to methods of weaving terry fabrics and the resulting article, and can be practiced on terry looms of conventional types. p p

The object of the invention is to ensure the production of pile of uniform height throughout the .width of the fabric.

In terry looms two sets 'of warp threads are used, one called the body warp for,

making the body of the fabric and the other called the terry warp for making the loops which form they pile. In loomsiof modern construction the terry warp is let o'lf at a uniformrate, but in looms of older type the terry warp was drawn off against frictional resistance; The invention is capable of practice by the useof either type of loom, but better results are secured withaipositive let off. I

' During weaving the filling is partially beaten up for a series of picks, of filling (commonly two or three), and thenon the ensuing pick (say thirdor fourth} all the picks of filling (three in a three pick terry and fourin a four pick terry) are beaten up fully to the fell of the cloth. The picks so beaten uplock, the terrywarp, but slide on the 'ground warp, so that the terry warp bendsinto loops," In doubled faced terry, half the loops extends upward and half downward. 1

In weave constructions heretofore used,

the first pick of filling of each group coacts with the second to lock theterry warp in the full beat up, and as the first pick of'filling is not laid straight, nor is it completely straightenedby the reed in its partial mo tion,-the terry-loops of a row tend to be low at that edge of the, cloth from which the shuttle starts in laying the first pick."

a (This difliculty has long been recognized and efforts to correct it have been made, usually by mechanical means which seek to straighten the first pick (see patent to Brown 1,657 ,429, January 24, 1928). Such mechanisms have not always proven'entirely pracef ticable, and even if practicable involve extra expense and complication. T l. The present invention overcomes this difficultyby a change in the weave structure such that the terry warp is lockedin the full beat up, by the second, thirdgand'fourth picks all of which are necessarily straight and parallel with the fell.. In the best mode of practicing the inventionnow known to me I produce a four pick terry in which .the first, second and thirdpicks of filling in, each group, are laid in'the same shed in the ground warp and the terry warp interweaves with the third pick. The fourth pick lies in a distinct shed in the ground warp, Perfect results can be secured inthis way. The invention will now be described as practiced to produce four pick double faced terry.

In the accompanying drawings, Fig; 1 is a diagrammatic longitudinal sec tion through a piece of double faced, four pick terry cloth woven according to the'present invention.

Fig. 2 is a plan view terry cloth in the process of weaving, showing how the first pick of a group of four is partially beaten up by the reed. i

of such piece of Fig. 3 isa similar view showing the second "TENT" OFFICE CAROLINA, A co'nroim'rroiv OF NORTH sition assumed by them in partial beatup,

i. e. the closest approach to the fell 9. The first pick of filling of the four forming a group appears at 12 andis. picked in the direction of thearrow on Fig. 2. The second pick appears at .13, (Fig. 13),andfis rigge. a a

Examination of these figures makes it clear that the firstpick 12 extends obliquely from the fellat the s'elvage to'the line established by the partial approach of the reed toward the fell, but that: the second pick 13 is straightened. by the reed for the full width of the cloth. I 1 i picked in the directionof the arrow in It will nowbe apparent why weave struc-i I tures in, which the first the terry warp. have short loops adjacent the selvage, The present invention avoids locking of the terry warp by the first pick, ensuring that no pick earlier than the second of a group takes part in per forming this fLHlCtiOil, and that such pick is necessarily parallel with the fell of the cloth.

Referring now to Fig. 1, ground warp threads appear at 7 G and terry warp threads ati7 The fell of the cloth is at 9 and the portion of the diagram to the right of 9 is woven cloth. Thus between the lines A A and B -13- are four picks of filling 12, 13, 14, 15 which have been beaten up as a unit. Between the lines BB and 0-0 is asimilar unit of four picks 12, 13, 14 and 15. In each unit 12 is the first pick, 3 the second, 14 the third and 15 the fourth. Picks 12, 13 and 14 are in the same shed in the ground warp; Pick 15 v(the fourth) is in a different shed formed in the ground warp. The terry warp threads interweave with (loop around) the third picks 14 and float as terry loops between the third picks of successive groups' The portion of the diagram (Fig. 1) to the left of the fell 9, shows, between the lines CC and D'D a group of four picks about to be beaten up to the fell by the reed dents 11. This makes it'clear how the second, third and fourth picks 13, 14 and 15 lock the terry warp threads 7 and why the first pick 12 takes no partin locking the terry warp.

While I prefer a four pick terry the invention may be embodied in terry fabrics of four or more picks.

The invention may be embodied in terry fabrics in which patterns are produced by pattern mechanisms, controlling the direction in which the terry loops are formed, and in which terry warps of single or contrasting colors are used.

What is claimed is:

1. The method of producing terry cloth, using a ground warp and a terry warn, which consists ininterweaving filling with the ground warp in groups of four picks, said group when formed being spaced from the fell of the cloth to which it is to be added, the first, second and third picks being in a single shed in the ground warp, and the fourth pick in a different shed in the ground warp, the terry warp being interwoven with the third pick; then beating up the entire group to the fell; and repeating the opera tion. 7 l i 2. Themethod of producing terry cloth, using a ground warp and a terry warp, which consists in interweaving filling with the ground .warp in groups of at least four picks, said group when formedbeing spaced from the fellof the cloth to which it is to be added, at least the first three picks being in a single shed in the ground warp, the remaining pick or picks being in a. different shed in the ground warp, the terry warp being interwoven with the last pick in the first shed; then beating up the entire group to the fell; and repeatingthe operation.

3. The method of producing terry from a ground warp and a terry warp, which c0nsists in laying filling in sheds, formed in the ground warp, in groups each consisting of four picks, the first, second and third picks being laid in the same shed in the ground warp, the fourth pick being laid in a difi'erent shed in the ground warp, and the terry warp interlacing with the third pick and floating to form loops between the third picks of successive groups; partially beating up successive picks as they are laid; and completely beating up the entire group after the fourth pick is laid.

' The method of producing terry from a ground warp and a terry warp, which consists in laying filling in sheds, formed in the ground warp, in groups each consisting of at least four picks, at least three picks beinglaid in the same shed, the remaining pick or picks being laid in a different shed, and'the terry warp interlacing with a pick in the first shed other than the first or second and floating to form loops between such interlaced picks of successive groups; partially beating up successive picks as they are laid; and completely beating up the entire group after the last pick is laid.

5. That improvement in the known method.

of producing terry cloth in which a ground warp and a terry warp are used and a group of picks of filling is interwoven with the ground warp and at least one of said picks is interwoven with the terry warp-while said group is spaced from the fell of cloth previously formed, and the group is then beaten up to said fell, which improvement consists in isolating the first pick of filling from binding engagement with the terry warp by'a second pick of filling laid in the same shed.

6. That improvement in the known method of producing terry cloth in which a ground warp and a terry warp are used and a group of four picks of filling is interwoven with the ground warp and one of said picks is interwoven with the terry warp while said group is spaced from the fell of cloth previously formed, and the group is then beaten up to said fell, which improvement consists in placing the first and second picks of each group in the same shed in the ground warp, and interweaving the terry warp with the third ick.

7 That improvement in theknown method of producing terry cloth in which a ground warp and a terry warp are used and a group of at least four picks of filling is interwoven with the ground warp and one of said picks is interwoven with the terry warp while said group is spaced from the fell of cloth previously formed, and the group is then beaten up to said fell, which improvement consists in placing at least three picks in the same shed in the ground warp, interweaving the terry warp with the last pick thereof.

8. A terry fabric of the type having not less than four picks of filling per terry loop, in which at least the first three picks are in the same shed in the ground warp.

9. A terry fabric of the type having four icks of filling per terry loop, in which the first, second and third picks are in the same shed in the ground warp. I

10. A terry ftbric of the type having not less than four picks of filling per terry loop,

in which at least thefirst three picks are in the firstshedin the ground warp, and the terry warp is interwoven with a pick in said first shed later than the second pick.

11. A terry fabric of the'type having four picks of fillingper terry loop, in which the first three picks are in the same shed in the ground warp, and the terry warp is interwoven with the third pick.

12. A terry fabric of the type having at least four picks of filling per terry loop, in which all the picks except the last are in the first shed in the ground warp, and the terry warp is interwoven with the next to last pick.

In testimony whereof I have signed my name to this specification.
