It is easy to operate simply and directly .The wire may use copper wire and galvanized wire.The welded double loop tie machine is stronger than that produced by the general machine.And the price is a little higher.We will also custom-produce diameter and lengths to your requirements. The double loop wire ties as a binding wire used in packing or construction. It is easy to operate simply and directly,Enhances the working efficiency, reduce pollution. Loop tie wire is coated with PVC to create a strong, easy-to-use twist wire tie. PVC coating will not crack, chip or scratch off when tying; meantime this coating provides protection against rust and corrosion. It is widely used for tying and support of plants in gardens or other binding uses, such as tying of sacks and other bagging. This kind of wire is also widely used in securing the position of reinforcing bars during concrete placement.

Spring forming machine

My invention is concerned with machines used. in forming coiled springs of the type-used in bedsprings. It is customary in such springs to wrap or knot the end of the wire of which-the'spring is formed around the next to the last turn of the spring; andit is the primary object of my invention to provide a wrapping mechanism in association with the spring-forming machine, to provide transfer means for carrying the completely wound spring to the wrapping mechanism, and to provide a second transfer means which will remove the springs successively from the wrapping mechanism and stack or nest them. More specifically, it is my object to provide for a springcoiling machine a unitary attachment which will include the wrapping mechanism, the two transfer mechanisms, and means for operating them in timed relation with the spring-coiling mechanism.
A further object of my invention is to provide, in a machine for coiling conical springs, an attachment by which the stock wire may be partially withdrawn from the machine after a completed spring has been cut from it to permit it to be repassed later through the forming rolls and bent at a different curvature.Get more news about spring forming machine producer,you can vist our website!
The accompanying drawings illustrate my invention: Figs. 1 and 2 are front a'nd'end elevations respectively of the complete machine; Fig. '3 is a plan of the complete machine; Fig. '4 is a detailed view illustrating the mechanism by which successively formed springs are nested; Fig. 5 is a fragmental front elevation of the machine on an enlarged scale showing details of the coiler, the wrapping mechanism or knotter, and the two transfer devices; Fig. 6 is a fragmental view similar to Fig. 5 showing the parts of the knotter in a different position; Fig. '7 illustrates the knotter in plan; Fig. 8 shows in plan the detailed construction of the transfer device by means of which the formed spring is carried from the coiler to the knotter; Fig. 9 is a front elevation of the same transfer device; Figs. 10 and 11 are vertical sections on the line AA of Fig. 9 illustrating different positions of the jaw-operating parts of the transfer device; Fig. 12is a front elevation of a mechanism employed for withdrawing the stock wire after-a spring has been-com pletely coiled and -severed';-and;Fig."13 is avertical section on the line 13-13 of Fig. 1, showing i an elevation qfthe transfer device bywhich the springs are carried from;the-.knotter to the rack on whiohthey arenested. f a
My invention is not primarily concerned with details of the spring cilingmachine. Such machines are well known and, for my present purpose, need not be fully described. I 'I'hespring-forming machine illustrated in the I drawings'comprisesa frame 10 carrying two-.op-g I posed feed rolls 11 and 12 which draw thestock wire 13 from a supplyreel (not shown) hrough' a straightener 14. The wire, after leaving the rolls 11 and 12, passes through a set of threeforming rolls best shown in Figs. 5 and 12. Theforming rolls, as indicated, are three in number and comprise two rolls 16 and 17 mounted on fixed Y axes in positionto engage opposite sides of the wire 13 at its spaced points; The third forming roll 18 is carried in a support 19 and is movable with such supportltowar'd and away from the roll 17 to vary the curvature ofthespring-coils. j
The pitch, or'axial spacing of thejspring-turns, v is controlled by a plate 21 having 'an incline'd f spring-engaging face 22. -As the springis being a j wound, the plate 21 is moved inwardly out- 2 wardly by suitable mechanism in order etra/m the desired spacing of successive spring-turf s.
