' TEMPLE ROLL Charles Thomas Dickey, Elizabeth, N. 3., assignor to Rodic Rubber Corporation, Garwood, N. J., a corporation of Delaware Application Ma h 25, i939, Serial No; 264,065 4 Claims. (c1. 139-296) This invention relates to a rollfor use in a loom temple.

As is well known to those. skilled in the art,-

-10 rayon or cellulose ester filaments as acetated cel-= lulose, or those of a fine and delicate nature, it

has long been customary to have the surface of the roll which, engages the cloth composed of rubber or rubber composition.

15 The ideal temple roll according to my experiements, is approached wherein a permanent thermoplastic, neutral compound is used as the templeroll, and has imbedded therein a multiplicity the form of roll embodying the invention located.

of outwardly-projecting fixed fiber ends to whicli 20" the frictional-gripping capacity is primarily due, that is, wherein thefriction results primarily from a number of frayedflber ends immovably imbedded, contacting the delicate filaments con-' stitutingthegoods being processed. g5 "I'his invention is a continuation in part of my copending application Serial No. 249,207, filed January 4, 1939 for Temple roll and process of manufacture.'

a One of the objects of the present invention is. aoto provide a construction of that type of temple roll employing a non rubber body, in which the above indicated and other disadvantages are substantially non-existant, as will be herein more particularly pointed out.

Another object is to provide a temple roll having the initial desired frictional gripping surface, which remains uniform and substantially unimpaired for an indefinite period of time.

A third object is to provide a temple roll of re- 40 quired frictional gripping surface which is unacted upon and unimpaired by any of the components of, in, or evolved incident to the textile being woven.

A further object isto provide a temple roll 45 wherein the surface passing in contact. with the cloth, does not leave a marker streak, or deposit material-on the goods, as is the case where a rubber-faced roll is 'used, especially when the rubber has been softened by the fumes from the fila- 50 ments being woven. This is an important point because the goods, are plain woven white and afterwards dyed. Even if an almost unnoticeable streak is left on the goods from deposition oftinytraces of rubber, this materially interferes with,

uniform penetration ofv dyestu'fi in the dyeing enlarged screw-threaded heads 6 which are tightly operation for the reason that rubber is absolutely insoluble-in water, and the result is that uneven and unlevel dyeings result.

Other objects of the invention will appear more fully and clearly from the accompanying descrip- 5 tion 'and drawing, and will be particularly I pointed outin the claims.

The general nature, function and purpose of a loom temple of the roll type are so well known and familiar to those skilled in the art, that it 10 here only becomes necessary to illustrate a portion of one typical form of a temple, together with preferred forms of the invention embodied there- 1 In the drawing and illustrative examples are, shown and described several preferred forms of temple roll embodying my invention.

Fig. 1 is an end elevation of a temple head with therein; Fig. 2 is a topplan view of the construction.- shown in Fig. 1; f

Fig. 3 is a face view of one of the units from which the roll is fabricated;

Fig. 4 is a side. view of the unit shown in Fig. 3; r i l Fig. 5 is a longitudinal cross section through a fabricated roll in an intermediate stage of manufacture; r

- Fig. 6 is a longitudinal cross section through a finished roll. a

The invention is shown in connection with the usual type of temple wherein two rolls are rotav tively mounted. The temples are arranged in pairs, one at each side of the loom, and may be termed right-handed and left-handed' since their function is to laterally stretch the cloth being .woven to the right and left side of the loom. The construction of the temple roll isthe same in both cases and therefore only a right-handed temple 40 roll has been illustrated.

The form of roll embodied in the present invention is adapted for use in substantially all types of roll temples.

The temple illustrated in Figures 1 and 2 comprises an. arm I, of which only a portion is shown and by which it is mounted upon the loom at the forward end, and a main body portion or pod 2 formed thereon having a trough-like shape in which the rolls are mounted. The temple rolls are journaled on pins 3 supported in the end walls of the pod 2, the inner ends 4 being fitted into the end wall 5 and the outer ends being provided with threaded into the end wall 'I.

9 and grooves I are later formed is fabricated,

or built up of a plurality of washer-shaped members I in which the outside diameter is slightly greater than that of the finished roll and the diameter of the hole I is slightly larger than pins 3. A suitable rod or mandrel of steel or other suitable material is shown at lb of Fig. 5.

To construct the roll 8, the proper number of impregnated washer-like members M are closely 'placed on the rod IS in sufilcient number so that when compacted together, a temple roll of the desired length will be formed. The rod with its assembled washers l4. thereon, is then subjected to pressureand heat, in a device having dies with an internal configuration which will compress, distort, groove and furrow the substantially cylindrical shape of the series of members it into the helically arranged ridges 9 and grooves N) of the finished roll 8. During this operation the members It are so compressed and merged into one another that they form a highly resistant, substantially one piece unit having the characteristics desirable in a temple roll.

After the compression operation, the rod, which has been used to aline the washer-like members, is removed, leaving the temple roll as shown in Fig. 6. If desired, the temple roll may be molded withone or both ends of small outer diameter than the rest of the temple roll. In the drawing, Fig. 6, illustrates such a roll with one end of smaller outside diameter.

The members l4 are preferably of woven natural or artificial fibers or admixtures thereof as cotton, linen, wool, silk or rayon, and impregnat-' ed with a thermoplastic body or bodies which are substantially unaffected by the fibers being woven, or materials contained therein or evolved therefrom. And conversely, solvents, non-solvents, diluents, softeners and plastieizing bodies used in conjunction with the impregnating mate-.

rial must be substantially devoid of solvent action upon the filaments constituting the textile being treated. W

Suitable impregnating bodies for this purpose are cellulose derivativesin the thermoplasticized "condition as cellulose esters and ethers, or a thermoplastic natural or synthetic resinous body or mixtures thereof, or a thermoplastic mixture of cellulose derivative and resinous body in proportions varying with the chemical composition and physical constants of the same.

In carrying the above method of my invention into effect, I may take 4 pounds avoirdupois of ten ounce duck, drill or canvas, and permeate or impregnate the same with a resinous body of the vinol type rendered fluid by solution in a volatile petroleum hydrocarbon mixture or other solvent or solvent combination, preferably of such flowability as will thoroughly permeate the woven' equivalent.

arca es In an alternative method, the woven fiber may be impregnated as in the previous example, using a cellulose derivative as an etherized cellulose, preferably of relatively high degree of etherification as, for example, highly ethylated ethylcellulose or highly benzylated benzylcellulose, or mixtures of the same, with suitable solvents and thermoplasticizing bodies if desired.

A plurality of such impregnated textile sheets are then stacked one upon the other, in a numher so that when pressed together into a unitaryappearing body, a slab of thickness equivalent to the desired length of the finished temple roll is formed.

The plurality of sheets are then compacted in any suitable manner.

The impregnated sheets after being compacted into a unitary block or slab of thickness approximating the length of the plurality of washer-like members I4 shown in Fig. 5 are then cut in a direction perpendicular to the long axis of the threads, so as to form unitary hollow cylindrical bodies with inner diameter nearly equal to the outer diameter of pin 3 and of outer diameter substantially thesame as I 4, and in appearance will be the equivalent of l4 in Figure 5, except that the plurality of l4 shown mounted on 16, is replaced by a unitary member.

Compression is then applied as described in the previous example, to produce the equivalent of the finished temple roll shown in Figure'l.

In the foregoing examples, after removal from the press, the helically arranged ridges 9 are more or less rounded from thermoplastic thereon. The final operation is a grinding or abrasive treatment whereby 9 is smoothed until a flattened-face is formed, as shownat 9 in Figure 6.

The plurality of woven or unwoven threads may be dyed, mercerized or otherwise treated before impregnation, and the impregnating medium may be colored as by addition of dyestufi or pigment.

The important feature of this invention resides in, and its efficiency depends upon, the relative percentage of raw edges of outwardly-projecting fibers constituting as the fabric-engaging surface the periphery of I 4 of Figure 5, compacted and held together by a therm plastic body not deleteriously efl'ected by co ponents in, or evolved from, the fibers or filaments passing over the same, constituting the helically raised ridges 9 of Figure 6, wherein the surface of 9 is substantially parallel ,with the inner cylindrical hole I5.

I claim:

l. A temple roll of a unitary body composed of a helically grooved cylinder comprising a plurality of compacted layers of woven fiber with outwardly-projecting ends embedded in a thermoplastic synthetic resin of the polyvinyl type said temple roll being adapted to engage a cloth surface without damaging the same, and retain a satisfactory uniform cloth-engaging, frictional-gripping 'surface during the wearing of said surface.
