Detailed Description

Embodiments of the present invention will now be described with reference to the drawings, wherein like parts are designated by like reference numerals. The embodiments described below and the technical features of the embodiments may be combined with each other without conflict.

The object of the present invention is to knit the fabric in a method of knitting the upper part of the heel with the face part of the heel in a mesh (commonly known as a hole), and fig. 1 shows a schematic view of a shoe upper, but the present invention is not limited to the application to the shoe upper. The vamp is sock-shaped, can be adhered to the sole to form the shoe, is very breathable due to the mesh, and is suitable for wearing in summer.

Fig. 1 shows the mesh being made between the upper heel part and the heel part of the sock, and the method of the present invention is not limited to these parts.

The idea of the method of the invention is as follows: the triangular track of the circular knitting machine is matched with an external needle selector, and a knitting needle to be operated and a transfer needle are selected to enter a knitting state to form meshes when knitting follows. The knitting method is formed by the circular knitting machine running in the same direction. In the prior art, the common knitting technology is formed by forward and reverse rotation of a circular knitting machine for a certain angle when a heel is knitted.

The method of the invention is described below with reference to fig. 2-4, as fig. 2 and 4 show a schematic view of the planar development of a circular knitting machine.

As shown in fig. 2, when the circular knitting machine is rotating within the set angle range, the control system controls the cam track, and the needle to be operated and the transfer needle are selected in cooperation with the selector to enter the knitting state, and knitting is performed to form a mesh. The triangular track is provided with: transfer cam 114, narrowing cam 117, transfer assist cam 118, fixing cam 115, transfer exit cam 116, and stitch cam 119.

The transfer cam 114 serves to withdraw the loop of the knitting needle 111 to the shank portion of the knitting needle 111. The draw cam 117 is disposed in front of the transfer cam 114 (i.e. the direction indicated by the arrow in the figure is the needle moving direction) and is used for drawing back the needle 111 which moves at the upper end of the track of the transfer cam 114, so that the loop on the needle bar of the needle 111 rises to bring the latch to close, and the loop is withdrawn from the needle 111.

The transfer cam 116 is disposed below the narrowing cam 117, and functions to raise the transfer needle 113 along the upper end trajectory of the transfer cam 116, so that the knitting needle 111 and the transfer needle 113 perform a stitch alternation onto the transfer needle 113 at the crossing position.

A transfer assist cam 118 is arranged in front of the draw cam 117 for transferring the loop of fabric from the transfer needle 113 to the needle 111.

A transfer draw cam 115 is arranged below the transfer assist cam 118, the function of the transfer draw cam 115 being to re-transfer the stitch on the transfer needle 113 to the shank of the needle 111.

In fig. 3, Z1-Z6 represent 6 needles 111. Each knitting needle 111 is controlled to ascend or descend by a corresponding one of the selector jacks 112, so that one loop is knitted. When the selector jack 112 selects the knitting needle 111, the knitting needle 111 enters knitting. When the selector 112 does not select the knitting needle 111, the knitting needle 111 does not perform knitting.

The knitting needles Z1 to Z4 are normally knitted, and when the fabric is transferred to a tissue with a set mesh, the knitting needle 111 is engaged by a selector to change the knitting needle 111 to a 1*1 state (i.e., every other needle, as shown in FIG. 4, 2*2 and the like may be used as necessary), the knitting needle 111 is pneumatically moved into a transfer cam 114, and a part of the knitting needle 1*1 is allowed to be knocked over to a needle bar below a latch along a trajectory of an upper end of the transfer cam 114. The needle 111, which is in motion at the upper end of the path of the transfer cam 114, is then retracted by the draw cam 117, at which point the loop on the needle bar is transferred to the transfer needle bar. While the needle closing cam 117 closes the needle, the transfer needle 113 is raised along the upper end trajectory of the transfer needle-out cam 116, and the knitting needle 111 and the transfer needle 113 alternate the stitch of fabric onto the transfer needle 113 at the crossing position. After the alternation of the knitting needle 111 and the loop weighing needle 113, the knitting needle keeps running along the upper end track of the transfer auxiliary triangle 118. The transfer needle 113 is moved along the lower end of the transfer closing cam 115 to close the transfer needle 113, and the knitting needle 111 and the transfer needle 113 alternately feed the loop of fabric on the transfer needle to the knitting needle at the upper end of the transfer auxiliary cam 118 at an intersection point, and the entire transfer operation is completed.

When the mesh needs to be knitted, the knitting needle at the mesh position is transferred. For example, in fig. 3, the loop of the knitting needle Z4 is transferred to the knitting needle Z5, thereby forming a mesh.

As shown in fig. 4, after the normal rotation reaches the designated angle, all the workpieces are operated in the reverse direction, at this time, the needle selector retracts all the transfer needles 113, the transfer cam 114 and the transfer assist cam 118 are withdrawn without taking part in the operation, and only the transfer take-up cam 115 is left for performing the normal knitting.

During ordinary knitting, the transfer cam 114 and the transfer assist cam 118 are withdrawn (the transfer cam 114 and the transfer assist cam 118 are movable in the radial direction of the needle cylinder, when the mesh needs to be knitted, the transfer cam 114 and the transfer assist cam 118 are pushed inwards into the motion trail of the knitting needle of the needle cylinder, and are withdrawn outside the motion trail of the knitting needle during ordinary knitting), the motor operates reversely, at the moment, the selector controls the selector to form an ordinary knitting trail, all selected knitting needles take in along the needle selection track, and when all the taken knitting needles are transferred to the stitch cam 119, the knitting needle 111 takes in along the track at the lower end of the stitch cam 119 to complete ordinary knitting.

The above operation is repeated for the entire heel and heel, and a fabric having meshes for the entire upper part of the heel and the face of the heel can be completed, and of course, a mesh having meshes for the back of the foot can be knitted.

The method of the invention is to transfer the loop in the positive direction when the circular knitting machine weaves the heel and the heel, which is completely different from the common knitting method of finishing the loop transfer of the heel and the heel in the reciprocating way.

The invention also proposes a shoe upper having a mesh knitted by the aforementioned method. The upper knitted by the method of the invention has a mesh and is therefore particularly breathable, and the toe portion after knitting is frail. When the vamp is adhered to the sole, the thread ends cannot be exposed, and the appearance is not influenced. And the method of the present invention weaves the upper without the dashed lines.

The above-described embodiments are merely preferred embodiments of the present invention, and those skilled in the art should be able to make various changes and substitutions within the scope of the present invention.
