A method for making an anti-skid apparatus for an automobile tire includes coating a plurality of core materials with rubber to form a plurality of cords; placing the cords in grooves of a preliminary molding plate and knitting the cords to form a net body; molding the cord into a non-vulcanized net body which inherently possesses crossing sections-where one of the plurality of cords lies on top of another of the plurality of cords; pressing the crossing sections so as to cause the core materials at the crossing sections to become linearly aligned; and vulcanizing the pressed non-vulcanized anti-skid net bodies to form a vulcanized net body. The step of pressing the crossing sections temporarily fixes the respective cords to each other at respective crossing sections. Also, affixing elements are attached to the vulcanized net body to detachably secure the vulcanized net body to an automobile tire.

Method of making an anti-skid apparatus for an automobile tire

An anti-skid net body for a tire includes a plurality of cords having crossing portions and open portions, with the crossing portions having a flat shape. At least one rope is fixed to an inside portion of the net body. An actional band and a setting band are detachably connected to an outside portion of the net body, wherein the setting band is connected prior to connecting the actional band, thereby tightly fastening the anti-skid net body to a tire.
