Shaping cam 12, as shown in Figure 1, 2, its cam body 121 is blockss, can its bottom surface or the side be fixed on the frame of equipment, the driving surface 122 of shaping cam 12 is planes, this driving surface 122 is a leaning angle of setting at shaping cam 12 fixed installations line of centers rear and center shaft 14 (or oviduct 22 of bolster assembly 2), this leaning angle is to be determined by different oviducts 22 specifications, usually can be asked for by simple graphing method, the cambered surface 123 of shaping cam 12 is to be operation setting;

Holddown spring 13 is common coil springs, and an end of holddown spring 13 holds the convex shoulder at center shaft 14, and its other end is to hold on the support body 112 end recesses end faces of bolster support 11;

Center shaft 14 is shouldered axis bodies, and center shaft 14 is that support body 112 endoporus that stretch through at bolster support 11 are bearing fit, center shaft 14 be installed in form bolster support 11 on the frame of equipment can be moving around its center string pendulum.

Bolster assembly 2 comprises Transmission 21, oviduct 22, yarn 23, its structure and shape are all same or similar with prior art, as shown in Figure 3 the oviduct 22 of this assembly and around the volume yarn 23 state, wherein oviduct 22 is usually made of plastic, it is one-body molded to include the pipe conical surface 221 and tubing string face 222, yarn 23 forms external cylindrical surface 231, male cone (strobilus masculinus) 232, inner conical surface 233 and inner cylinder face 234 around volume respectively on the oviduct 22 of setting under the setting campaign of idler assembly 3, groove drum 4 and shaping mechanism 1 cooperates.

Idler assembly 3 includes carrying roller body 31 and roller carrier shaft 32, its structure and shape are all same or similar with prior art, roller carrier shaft 32 is dragged by motor usually, and rely on carrying roller body 31 and the oviduct 22 of bolster assembly 2 or the contact friction transmission of yarn 23, form oviduct 22 and rotatablely move and axially movable power.

Groove drum 4 comprises cylindrical shell 41 and cylinder axle 42, its structure and shape are all same or similar with prior art, cylinder axle 42 normally driven by power rotation and and roller carrier shaft 31 synchronous, plug helix on the cylindrical shell 41 forms yarn along oviduct 22 axial winding displacement actions when cylindrical shell 41 rotation, make yarn 23 evenly distributed around twisting on the oviduct 22.

Principle of work of the present invention is: the requirement of trumpet pipe winding be with yarn 23 with the mode network of Fig. 3 on oviduct 22, yarn 23 forms respectively external cylindrical surface 231, male cone (strobilus masculinus) 232, inner conical surface 233 and inner cylinder face 234, wherein external cylindrical surface 231 is parallel with inner cylinder face 234, and inner cylinder face 234 amplexiforms the pipe conical surface 221 at oviduct 22; Idler assembly 3 carrying roller bodies 31 frictions of constant speed rotation drive bolster assembly 2 and finish coiling, the groove drum 4 of constant speed rotation moves yarn 23 in its groove, finish fro guiding-yarn between A shown in Figure 3, the B at 2, be that initial guide is between 2 of A, B, the full packages guide is between 2 of A ', B ', and yarn 23 just becomes large cylinder with certain intersection angle network like this; In the process that above-mentioned cone winder diameter around rolling up increases, make the male cone (strobilus masculinus) 232 of the upper yarn 23 of pipe that splits form two parallel circular conical surfaces with inner conical surface 233, must change the oviduct 22 of bolster and the relative position between the groove drum 4 guide strokes, make it to occur as Fig. 1 arrow C to displacement, be the longitudinal travel of oviduct 22, make the guide stroke traversing to A ', B ' from A shown in Figure 3, B.Its strained condition and corresponding actions are shown in Fig. 4,5: in the winder process, 3 pairs of bolster assemblies 2 of idler assembly (oviduct 22) application force N is the prime power of bolster assembly 2, it also is the prime power of shaping mechanism 1, travelling wheel 110 is subject to two power F and K all the time in the winder process, its F is the lever force of N, K is the application force of 13 pairs of bolster supports 11 of holddown spring, when doff, along with yarn 23 diameter around volume on oviduct 22 increases, bolster support 11 swings centered by center shaft 14, and the θ angle increases; Travelling wheel 110 and rolls at the driving surface 122 of this inclination on the driving surface 122 that is pressed on shaping cam 12 under the force action of F and K; Utilize power N to swing along conter clockwise to (direction shown in Fig. 4 arrow) for the elastic force that propulsive effort makes bolster support 11 overcome holddown spring 13, and move axially simultaneously, this moment, the reduction length of pressing spring 13 shortened, the guide stroke is traversing to A ', B ' (shown in Figure 3) from A, B, finishes trumpet pipe winding conical surface moulding action with mechanical structure.
