Problems solved by technology

[0006] It is not difficult to see from the structure and production process of the above-mentioned ball that when the traditional ball is formed, the edges of the skins 5' are exposed because each skin 5' is attached one by one along the slightly protruding boundary mark 32' of the middle tire 3'. On the surface, it is easy to warp over time
In addition, because the cavity of the traditional die 8' is smooth, the arc region connected between the skins cannot be squeezed well, so that the surface of the skin 5' and the rubber middle tire 3' are closely connected. Will take some hits, equally prone to warping at the seams
Not only that, but in traditional finished balls, the radians of the skins are wide and unnaturally beautiful, and there are easy gaps between the skins, exposing the color of the rubber underneath, so that the patterns printed on the skins are visible on the finished ball. It is easy to show disconnection and discontinuity on the surface, which will affect the appearance and quality of the finished ball

Embodiment Construction

[0033] Such as Figure 4 shown, while coordinating Figure 9 , 10 As shown, the production process of the rubber ball in the present invention mainly includes: making the inner tube → winding silk → forming the inner tube → gluing → pasting → printing. in:

[0034] (1) Making the inner tube:

[0035] The inner tube 1 can be made of rubber material with high elasticity and good air tightness, so that the inner tube made has excellent bounce and excellent air tightness, thereby realizing that the finished ball also has excellent elasticity and superior air tightness. Tightness.

[0036] (2) Wrapped silk:

[0037] Wrap uniform yarn on the outside of the inner tube 1 that has been made to form a silk wrapping layer 2, so that the middle tube and the finished ball with skin have a stable and fixed range of circumference and excellent roundness, and at the same time it has high durability. The impact strength also enhances the bounce of the mid-tyre. And be coated with viscos...

Abstract

The invention discloses a manufacturing technique of leather ball, which comprises making inner tubes, wrapping filament, forming middle pneumatic, sizing, sticking skin, printing pattern and other steps; wherein, a protuberant boundary line is arranged on the position of the middle pneumatic adding sulfur die cavity which is matched with the middle pneumatic film edge in the process of forming middle pneumatic; a concave groove is formed on the vulcanized middle pneumatic; the skin graft edge is pressed into the groove in the process of sticking skin; a protuberant blank holder is arranged on the position of the printing pattern mold which is matched with the skin graft edge via printing pattern by printing pattern mold; the blank holder is extended into the joint and extruded in the action of finished ball internal pressure, which makes the joint tight; the skin graft edge is uneasy to tilt as the skin graft edge is extended into the groove formed on the middle pneumatic; the butt-mounted edges of each skin graft are more even and without gaps, which makes the connection of pattern printed on the skin graft smooth; the approximately vertical radian among the skin grafts makes the leather ball the same stereoperception as hand sewn leather ball.

Description

technical field [0001] The invention relates to a production process, in particular to a production process of a leather ball. Background technique [0002] In the prior art, the sphere of a football (including football, volleyball, etc.) is usually a composite layer structure, such as figure 1 As shown, the composite layer mainly includes an inner tube 1', a silk-wrapping layer 2', a middle film 31', an adhesive layer and an outer leather sheet 5', and the middle layer is formed on a rubber film 31' wrapped with a silk-wrapping layer 2. After the inner tube of a tube 1 ' of ' goes up, promptly forms middle tire 3 '. Among them: the inner tube 1' is made of rubber material with high elasticity and good air tightness, so that the inner tube made has excellent bounce and excellent air tightness, so that the finished ball also has excellent elasticity and superior airtightness. air tightness. The silk-wrapping layer 2' is to wrap even yarns on the outside of the inner tube 1...
