A cordlike element to permit the-100193 to P oject t rough and a is fed through t neuter of t member by a fabric coverlB may enclose the entire assembly. 25 pair of grooved rollers and a stationary presser The-cover'ls is Preferably Stitched wi l and y, foot is mounted in spaced relation to the element if desired, have other Seams therein W e it in such o iti t t t member t t projects outwardly ofthe element H), the covered the wires will be wound around the element and Projecting 100138 forming a resilient a taching presser foot in overlapping loops. The rollers flahge as fully described in y copending appli- 30 serve to draw the loops from the presser foot and h I to compress the loops about the element to secure The illustrated machine for forming the Weat them thereto. From the rollers the core member f Strip comprises-a guide I810 e ve the e eis fed into a second set of rollers grooved to rement from a reel other suitable Source,
5 ceive the element and having substantially cylinnot Shown- From the guide the element as drioal portions t flatten t 100p Preferably over a suitable tensioning shoe l9 pivoted on a n of t second t of rollers is mounted on horizontal lever 2| which isurged by an adjusta rigid part of the machine and-the other on an able Spring 22 in a direction o p t e element adjustable lever so that the pressure exerted frictional'ly against e "guide 8 to maintain thereby on th loops and t 1 1; can be suitable tension thereon.

ings in which; formed-with a sprocket gear-28-by which it isv Figure 1 is a plan View t parts Section f driven. The carriage 25 carries a pair of spools a, machine embodying the invention; l 29 carrying the wires I l and l2, which pass from Figure 2 is a section on th lin 11-41 -'of Figthe. spools through suitable guide members '3I 50 ure 1; (Figure:2-)fand then one or more times around Figure 3 is a section on the line III-III of Fi'gtensioning rollers 32 which are arranged at diaure 2; metrically-oppositepoints and guide the wires as Figure 4 is a partial section on the line IV--IV they are wound around the element). The tenof Figure 1; and V 7 sioning rollers are held by frictionshoes 33 55 I journaled in a frame 43. The shaft 42 may be driven by a pulley wheel 44 belted to any suit able source of power. As the carriage 25 rotates, the wires II and 12 will be wound around the element 1 0 and around a suitable presser foot .45 whichis rigidly secured to the machine frame spaced from but substantially parallel to the element ID;
the wires into overlapping loops larger than the element I 0. As the element ID with thewires H and I2 looped around it passesthrough the rollers 23, the wires will be tightly crimped around'the element due to the grooves 24 and will preferably be stretched beyond their elastic limit so-there will be little or no tendency to spring back.
From the rollers '23'the core. passes to a pair of rollers 45 and 4'! formed with registering grooves 48 to receive the element Ifland with substantially cylindrical portions 49 between which the loops l4 are flattened .-out. The roller 45 is mounted on a horizontal spindle on a rigid frame member 5| and the roller 41' is mounted on a lever52 which is pivoted at oneend' on the frame! and has its otherend connected by a link- 53 to a lever 54 likewise pivoted on theframe 5 I. The frame 5| hasanextension 55 which carries a screw 56 adapted to engage the end of the lever 54. As will be apparent the screw 56 serves as an adjustment to contr'olthe position of .theroller 4l thereby to adjust the pressure exerted on the element l0 and the loops I4 by thelrollersl lii and 41. The two sets of rollers 23 and 46. and 41 are preferably driven by the power, shaft'42 and for this purpose a suitable gear drive .51 is-provid'ed driving a shaft 58. The shaft 58 is'apreferably connected directly to one of rollers 23 which are geared together by pinions 59. 3 The rollers 46 and 41 are preferably also geared together by pinions 5 I, one of which is geared to one of the pinions 59 by an idler pinion 62. In this way the speeds of all of the various elements are synchronizedso that the loops M will always be evenly spaced on the element l0 and there will be no tendency to break the element l0. While one embodiment'of the invention hasbeen illustrated and described in detail, it is-not to be understood that the scope of the invention is limited to that particular embodiment, or other.- wise than by the terms of the appended claims.
