Steel wire 102 is received first in first pulley 110.There are the pulley flat surfaces, reason will become clear later
Chu.Silk slightly contacts first pulley 110 to make its rotation.
Steel wire 102 is then brought to take turns 112,112 ' by a pair of forming.Forming wheel 112,112 ' can be taken rotatable
The form of disk, pin is by the Plane Installation perpendicular to rotatable disc on rotatable disc.The disk is equipped with intermeshing pin.Because
Pin is round, so they make steel wire particularly gently be bent.Optionally, forming wheel can be as described below the
Pitch wheel described in two embodiments.Flat waveform is introduced into and the axis perpendicular to forming wheel by forming wheel
In the parallel steel wire of plane, which is referred to as " single crimped filament 104 ".
The waveform being introduced into can use function f (z) to indicate, value indicates the deviation with the axis of steel wire, and in wavelength
Variation on " W ", between maximum value "+A " and minimum value "-A "." z " is the seat along the axis of single curled wire 104
Mark.Since waveform is periodic, so for any " z " value, f (z+W) is centainly equal to f (z).
Hereafter, single curled wire 104 is directed to second pulley 110 '.Second pulley 110 ' has flat table again
Face.In the inlet of second pulley, single crimped filament 104 will enclose 90 ° rotatable around its axis, to make the plane and second of curling
The flat surfaces of pulley 110 ' are aligned.Silk is then rearwardly guided across first pulley 110.In second pulley and first pulley
Between, the orientation of the single curled wire 104 ' of steering does not change.It is fed between forming is taken turns for second in single crimped filament
Before, first pulley 110 will keep the orientation of single crimped filament.During the second crimp operation, single crimped filament is with the first volume
The state that bent plane is parallel to the axis of forming wheel enters.When being taken turns by shaping, in the direction (example perpendicular to the first curling
Such as in the direction of Y-axis) on, silk will be given with the second waveform f (z) with the identical amplitude of the first curling and wavelength.
Equipment is characterized in that the axis of first pulley, the axis of second pulley and forming wheel is parallel to each other.
If the single crimped filament 104 ' of the steering at the second entrance of forming wheel and forming wheel 112,112 ' now
The occlusion inphase operation of tooth, then silk would tend to rotate in wheel and the deformation of the single curled wire 104 ' of steering will be stayed
In one plane.
However, by introducing phase difference " F " between first and second forming event, tooth will be in the curling of the first crimped filament
Between engage, and form three-dimensional spiral shape.For example, phase difference can be set at 1W/8 between 3W/8, it is therefore preferable to
W/4.When being projected on the X/Y plane perpendicular to Z axis, it will being formed has the convex of four corners close-shaped, uses equation x
=f (z) and y=f (z+F) are described.It is obtained forming saw silk shape be " square spiral ", that is, its along axis projection
It is the spiral of the quadrangle with pitch W.Therefore, because the curling given in two directions is equal, obtained silk 106 is not
Show preferred direction.
In order to control phase difference, the distance between first pulley and second pulley " Δ " must be adjusted so that change two
Length difference between a silk.The displacement " d Δs " of wheel by cause forming wheel inlet " 2 × d Δs " phase shift " F ".
In the alternative embodiment of the utility model as depicted in Figure 2, first pulley and second pulley are the same cunnings
Wheel：210.Here, identical silk in a pulley with flat surfaces above with twice.Straight wire 202 is by direct again
Ground is fed to first pulley 210.Silk is guided across a component 212 of a pair of of forming wheel, and passes through second pair of component
212 ' deformations.In this case, forming wheel can be in the form of two pitch wheels 212,212 ', gear 212,212 '
Tooth be round and gear 212,212 ' between gap remain the diameter of at least steel.Two measures are needed, to prevent
Make steel wire impaired when steel wire is taken turns by shaping.However, forming wheel equally can be the pin 112,112 ' with first embodiment
Disk.Single curled wire 204 is therefore obtained.
It is guided by the flat surfaces by the single curled wire across pulley 210, introduces single crimped filament 204 and surround it
90 ° of steerings of axis, to cause the single crimped filament 204 ' of the steering when leaving pulley 210.Curling is present in now
In the plane of pulley 210, it is ready to be given in a pair of forming wheel 212,212 '.When leaving forming wheel for the second time, shape
At silk 206 is sawed in the spiral-shaped forming in side, the axis of pulley 210 shapes the axis of the first component 212 of wheel with a pair
The distance between " Δ " be set to make the out-phase that engages of the curling of single crimped filament 204 and the tooth of forming wheel 212,212 '
Value.This can be realized by adjusting apart from " Δ ".The axis of forming wheel is once again parallel to the axis of guide pulley.
In the further preferred realization of both the above embodiment, a pair of forming wheel is provided with synchronizer 114,224.Together
The function of walking device 114,214 is the mobile synchronization made between the component of the forming wheel pair 112,112 ' or 212,212 '.When this at
When shape wheel with the half tooth between them away from phase difference to being synchronized, the maximum value+A of waveform f (x) will be declined with W/4, and it is minimum
Value-A will occur in 3W/4.
If phase difference between the component of the forming wheel pair deviates half tooth away from may cause the waveform of deflection.This
It is not problem.It should be noted that the phase difference " F " between first and second deformation will not be changed, because of two deformations
All it is to be manufactured between in identical forming wheel, and distance " Δ " can be better controlled.
Only when the phase difference between the component of the forming wheel pair can change (i.e. asynchronous steering is taken turns in forming) along length
When, the form of forming saw silk is also changed in online length.The shape of the variation in order to prevent, can use synchronizer 114,
214.Synchronizer can provide in the form of described in WO2015/054820 A1, wherein the first of the forming wheel pair and
Two components are connected by gear train.
