In this embodiment, there are 18 taping head dies 5, and in other embodiments, the number of taping head dies 5 can be reduced or increased according to the processing speed of different operators. For example, a reduction of 6 or 12 or an increase of 24 may be chosen. The tape head sticking mould 5 is fixed on the winding wheel 3 and can move along with the winding wheel 3. The winding wheel 3 is provided with mounting stations 31 for mounting the climbing belt head moulds 5, and the mounting stations 31 are matched with the number of the climbing belt head moulds 5.
As shown in fig. 5 and 6, the taping head adhering mold 5 is provided with a positioning groove 51 and a plurality of rope grooves 52 communicating with the positioning groove 51 and arranged in the length direction thereof, the positioning groove 51 being configured to position the leather lace 7 for making the taping head 61, and the rope grooves 52 being configured to position the rope 11 for making the taping rope 62. The leather strip 7 has a predetermined size to fit the size of the positioning groove 51 so as to be positioned. Through the design of the adhesive climbing belt head die 5, the leather strip 7 can be firmly placed in the positioning groove 51 of the die, the rope 11 can also be limited at a preset position through the rope groove 52, the positioning is accurate, and the centering and bonding precision is high. The leather strip 7 can be fixed in the positioning groove 51 by any suitable method, for example, by fixing the leather strip 7 with reusable glue, such as pressure-sensitive glue, which is readily available on the market. When the leather strip 7 is removed, the other leather strips 7 can be bonded and fixed again.
In the conventional manufacturing method, the appearance of the bridle head 61 is previously manufactured. However, in this embodiment, in order to solve the problem of slow and uneven glue application, the whole leather strip 7 capable of forming the plurality of taping heads 61 is glued and then bonded with the rope 11, the glue used may be white latex, and by such a method, the glue on the bonding surface can be ensured to be even. Namely, the lower surface of the leather strip 7 is fixed in the positioning groove 51 through glue, and the upper surface of the leather strip 7 is coated with glue for bonding the rope 11.
The size and shape of the leather strip 7 can be selected according to actual conditions, and in the embodiment, the leather strip 7 is rectangular, the length is 150mm, and the width is 21.5 mm. On the premise of ensuring the external dimension of the bridle head 61, a leather strap 7 with the above dimension can be cut into 15 bridle heads 61. Preferably, the leather strip 7 is made of sheep leather. The rope groove 52 is communicated with the positioning groove 51 to ensure that the rope 11 positioned by the rope groove 52 can contact the leather strip 7.
In this embodiment, two sides of the positioning groove 51 in the length direction are respectively provided with a limiting convex part 53 for limiting two ends of the leather strip 7. A plurality of positioning blocks 54 are respectively provided on both sides of the positioning groove 51 in the width direction, and a rope groove 52 is formed between the positioning blocks 54. Namely, the limiting projection 53 and the positioning block 54 basically limit the size of the positioning slot 51, and the leather strip 7 can be prevented from moving in the positioning slot 51 by the limiting projection 53 and the positioning block 54, so that the leather strip can be accurately positioned.

Since the leather strip 7 is coated with glue, the rope 11 is simultaneously adhered to the leather strip 7 when being wound on the leather strip 7. The number of blank units 8 corresponds to the number of taped die 5, i.e. in this embodiment the blank has 18 blank units 8.
Since the rope groove 52 is formed along the length direction of the positioning groove 51, the rope 11 is also distributed along the length direction of the leather strip 7 after the winding is completed. Each blank unit 8 of the blank may be cut out (i.e. the string 11 is cut) by a suitable cutting tool (e.g. scissors, a die cutter or a suitable die) and each blank unit 8 may then be punch formed by a die-head machine.
The bridle strap rope 62 in the prior art is cut in advance, and the tail of the rope needs to be collected after the bridle strap rope is manually stuck, so that the operation is quite inconvenient. In the embodiment, the rope 11 is not cut in the whole winding process, the rope 11 needs to be cut once after all winding is completed, and then the rope 11 is cut by the cutting tool to enable the rope 11 to have the preset length, so that the problem that the rope tail needs to be collected when the rope 62 is manually adhered is solved, and the length of the rope 62 is uniform.
As shown in fig. 7 to 11, the bridle wire head punching machine includes a punching die provided with a punching structure adapted to the shape of the bridle wire head 61 to punch and strip each blank unit 8 into a plurality of bridle wires 6, i.e., each blank unit 8 may mold a plurality of bridle wires 6. Wherein the holes of the bridle strap 6 in the bridle strap 6 are also punched and formed together. The punching die includes an upper die 9 and a lower die 10.
As shown in fig. 1 to 4, the driving device 2 includes a power source and an output shaft 22 driven by the power source, and the output shaft 22 is connected to the winding wheel 3 to drive the winding wheel 3 to rotate. The power source can be manual or electric, for example, in the embodiment, the power source is a hand wheel 21, and the rotation of the winding wheel 3 is realized by manually shaking the hand wheel 21. In other embodiments, a motor may be used instead of manual rotation to reduce labor intensity. The output shaft 22 may be directly connected to the drive device 2 or indirectly connected to the drive device 2. In this embodiment, in order to effectively utilize the space and facilitate the operation of workers, the hand wheel 21 is directly connected with the main shaft 23, and the main shaft 23 is connected with the output shaft 22 through the commutator 24, that is, an angle of 90 ° is formed between the main shaft 23 and the output shaft 22. Depending on the application, the commutator 24 may be a decelerating commutator 24, which decelerates simultaneously with commutation.
The rope guiding mechanism 4 comprises a lead screw driven by the output shaft 22 and a rope guiding structure 43 driven by the lead screw to move axially, the lead screw comprises a screw rod 41 and a nut 42 in threaded connection with the screw rod 41, and the rope guiding structure 43 is arranged on the nut 42. The axial displacement here refers to the axial direction along the reel 3.
The cord guide 43 serves to guide the direction in which the cord 11 exits. The rope guiding structure 43 is provided with a limiting opening 431 for the rope 11 to pass through and be limited so that the rope guiding structure 43 drives the rope 11 to move synchronously when moving.

In other embodiments, the transmission can be performed by a gear and a rack.
In the winding process of the rope 11, a worker rotates the main shaft 23 by shaking the hand wheel 21, and under the action of the commutator 24, power is transmitted to the output shaft 22 to drive the output shaft 22 to rotate, so that the winding wheel 3 is driven to rotate. The output shaft 22 drives the reel 3 to rotate, at the same time, the first synchronizing wheel 25 coaxially rotates, and drives the second synchronizing wheel 26 to rotate through the synchronous belt 27, so as to drive the screw rod 41 to rotate, further cause the nut 42 to axially move, and finally drive the rope guiding structure 43 to axially move. The winding wheel 3 draws the rope 11 to make a circular rotation, and the rope guiding structure 43 makes the rope 11 move axially, i.e. the rope 11 makes an axial movement while making a circular rotation, forming a spiral movement. Correspondingly, the grooves 52 form a spiral path so that the rope 11 is spirally wound. Meanwhile, the rope groove 52 penetrates the sticky flap die 5 in the path direction of the rope 11 for smooth winding.
