Specifically, the auxiliary member that uses in this embodiment is inside and outside double-deck overlapping structure, inlayer and skin are the opening design, the inlayer is placed in the skin, a plurality of locating holes have been seted up on inlayer and the outer lateral wall, adjust the degree of depth that the inlayer is located the skin from top to bottom according to the degree of depth that string bag 100 needs, insert the locating lever in the locating hole of inlayer and outer lateral wall, with fixed inlayer and outer relative position, so, place pocket form screen cloth 10 in the auxiliary member, just can adjust the degree of depth of string bag 100, the accuracy and the convenience of string bag 100 degree of depth adjustment have been guaranteed.
In some embodiments, in step (1), the open end 12 is wrapped around the collar 20 to ensure that the pocketed web 10 is smooth and pliable.
Thus, the adhesion effect of the subsequent glue is ensured.
In some embodiments, the glue is applied uniformly and without leakage in step (2).
Therefore, the normal work of the net bag 100 when in use is prevented from being influenced by the glue contacting other positions of the net bag 100.
In some embodiments, in step (3), the glue application position is baked by using continuous hot air.
So, guarantee glue and pocket form screen cloth, lasso and fully contact and bond, improve the stability that lasso and pocket form screen cloth are connected.
In some embodiments, the pocketed mesh 10 is made of a nylon material.
In some embodiments, ferrule 20 is made of stainless steel.
In some embodiments, the glue is polyurethane.
Therefore, the liquid polyurethane glue has good biocompatibility, is stable and is bonded for a long time, so that the net bag can not threaten human health when being used for manufacturing the net bag, and meanwhile, the service life of the net bag is ensured.
Therefore, the glue does not have side effect on human body, and does not generate rejection reaction or have adverse effect on human health when entering the human body for use.
In certain embodiments, in step (4), scissors are used to trim the location where the open end 12 and ferrule 20 are bonded.
Thus, the thread ends of the pocketed mesh cloth 10 are prevented from affecting the safety and stability of the string bag 100 during operation.
In the description herein, references to the description of the terms "one embodiment," "certain embodiments," "an illustrative embodiment," "an example," "a specific example," or "some examples," etc., mean that a particular feature, structure, material, or characteristic described in connection with the embodiment or example is included in at least one embodiment or example of the invention.
