This invention relateslto nets,as tennis f nets, which.- areprovided witha marginal band usually Vfor the suspension thereof, and ithas for its object to improve this portion of such apnet. Ordinarily this portion'of the net is formed by a'twofply band, ,as duck, which receivesfbetween` its plies the margin of thenetjpropeigthe two vplies and net Uproper. being securedtogetherl by stitching penetratng-allthree and extending length-4 wise ofthe band. This constructionisfaulty in thatit frequently happens; that `one or more strandswillfbe cutby the stitching needleso thatrif such'stra'nds are not @dis-v rupted at once they `will at least be so `far `weakened as to break whenthe netis inserv'- i i 4'view of such form;

:thereto in certain' other respects.

i Two forms of my invention are shown herein bywayfof example. Both are characterized by the securing of thebandplies or layers ,to the marginof the net proper, Ywhich intervenes between them, at spaced points a arranged successively lengthwise4 of .the bandand alternatingwith the strands, asy by means of rivets.` Bothv are also char acterized bysaid pliesxor layers vreaching beyond the net proper and having theirl freel .edgesv extending in opposite directions and lapping eachother land thereupon secured ltogether thus to form as it were a two-ply saddle to straddle the cable which shall beV devoid of any outstanding seam or welt that would exist ifthe two edges 4extended in the same direction and were secured together in that arrangement; but in one of these forms the two plies are constituted by separate pieces `whereas-in theother form they are partsof a single piece, the portion ofthe piece intervening between the plies vbeing' `itself` folded lengthwise so. as to arch'over the cable. In the preferred form, as indicated, use rivets as the means to secure the said band plies or layers to the margin of the nefPliOPeifv nd fI use them in such away thatth'eyare` not V only notvisible inthe-,finished net but that Y .any ,surface-unevenness. that they might otherwise produce atkv :,the'exposed. faces kof ig." l showsv a tennis` net-land .cablelin elevation and inl the first-mentioned 4form thereof; y f

f The bandvis here composed of two separate plies 3 4- of y suitable :strong fabric,;as duck,

usually .employed to form the to'pband of a 'tennis lnet, and these` are in this example secured to` the Anet proper as yfollows:l Having (lappedfoutward, asatyflongitudinal edge Sport-ions of the said Aplies and. placed the plies againstthe lopposite faces of the uppermar--` fginal portionofthefnet proper so` that Vthe ,folds of the laps project upwardly, the two .-theband is.avoided;'thev construction isualso Y further such that anysurfaceunevenness that jmightotherwisebe dueto the presenceof. knots of the netproper being ybetween the pliesfisavoided-,at the' exposed` faces of the bandi y u -f i., yIng-the drawing.. v i

F ig. 5 fis a vertically sectional perspective 1 4Vviewlof such other form; and l v plies, are riveted to each other and thenet lproperibyrivet's (iA penetrating all three, 7

being washers on the rivets. The rivets arey placed,; as shown, one after ,another length- -wiseof the bandandzeach soas to penetrate Y an,y openingV of the mesh of thenet and clear lof the strands thereof. The two plies are Y then folded outwardly and upwardly, as at `8, andv nallytheir upper and vproj ectingv edge portions are bentv in opposite directionsand made to lap ,each othervas shown at.9 andare secured togetheralong aline or` lines extendl ingilengthwise of theplies-,yas Aby stitching` -10 (a stitching machine adapted toperform such work on the g, eventually tubular band lOO Y being known" and requiring no description at this point.- lUsually the edgelof that ply` here); vthe'lap is so positioned that when the cable'Q is'present in the band the lap will rest on the cable and so form, as it were, the sad'dleportion of the band, which of course increases the durability ofthe band which laps outward, of the other ply at the top of the band will be lapped on itself, as at 12, so as to avoid the presence of an 'exterior raw edge.

Thus I not'only avoid any possibility of strands of the netbeing cutin assembling the band with the net proper but the net: ismade Vexceedingly strong andldurable, largely because at the points wherewear is most likely toi manifest itself-at the top and bottom of the bandthere are two ofr'more thicknessesV of material.. By'attaching' the plies tothe netproper as disclosed the yrivetsfor other attaching means Gare at once obscured by the pliesY and also une-vennes's at the exterior faces of the band is'substantially eliminated.

f vIn the formshown/by Figs.` 4'to;6 the same advantages'accrue. The two'plies 13and514 are integralv parts of the same strip of fabric which is folded'midway its Width and len h-V wise, as at 15, and receives'be'tweenthe ayersv 18a and 14a thus resulting the vupper edge portion ofthe net proper 1 to which f said layers are secured by rivets 16 arranged on the cablewhenv the 'same isA introduced; ,f

one after another lengthwise of the strip andv each sonas, to penetratean opening ofthe mesh y vofV the net and clear of thestrands; then the fianking or marginal portions of the stripV -are'folded .upwardly :and outwardly to produce the two plies 13 and'lr-'andtheir edge portions are bent in opposite directions and made to` lap each other, as at 18,V and secured together along line or linesextend'inglengthwise of the plies, as by'stitching19,=so that preferably thelap will` rest, saddle-fashion,

the outer edgeYportion' maybe lapped inwardly-,asiat 20, to avoid a raw edge'.4 Y

' Sali'ent and independently7 novel features of my invention are the'foldving of elongated plies-secured to the? interposed net `proper marginfby means Ypenetrating the plies and =net proper *and*` arranged lengthwiseofthe :plies-outwardly from the net proper'and so Y as tofextendf beyond said margin, together with securing of the plies togetherbeyond said margin, whether yor not their upper 'edges project oppositely and lap each other and' whether or not as so folded'they cover the securing means; the projection lof the outer or free edges ofplies in oppositedirec- VVtions and the lapping and securingfof themA together, however vthe plies may be other.-

wiseformed and assembled with the interposed-,margin of the net proper; and'fth'at i formation o'fsuchanet which is substantially shownl in Figs. 4to Gand characterized by a ,lengthwiseV substantiallyV midfold in an Velongated fabric strip, means to secure the Y two adjoining layers thus resulting to the interposed margin of the net proper, the folding of the margins of the stripv outward,-v ly and so as to project beyond the margin of the net proper, and means tosecure said strip margins togetherabove the margin of the net proper. v
