Method of manufacturing machine-laminated basketball

A method of manufacturing a machine-laminated basketball comprising:

• step a:
• winding a fabric on a surface of a bladder to obtain a winding on the bladder;
• step b:
• adhering a rubber sheet on the winding and wrapping the winding by the rubber sheet to obtain a carcass;
• step c:
• coating a first adhesive on an outer surface of the carcass to obtain a first adhesive layer on the carcass;
• step d:
• drying the first adhesive layer;
• step e:
• coating a second adhesive on an inner surface of each of multiple ball covers to obtain a second adhesive layer on each of the ball covers;
• step f:
• drying the second adhesive layer;
• step g:
• arranging and vacuuming the ball covers against inner surfaces of two hemisphere molds;
• step h:
• placing the carcass in one of the two hemisphere molds;
• step i:
• closing up the two hemisphere molds to form a sphere;
• step j:
• inflating the carcass to pre-laminate the ball covers on the carcass via the first adhesive layer and the second adhesive layers, so as to obtain a pre-laminated ball;
• step k:
• vulcanizing the carcass and laminating the ball covers to the carcass in a vulcanization mold, and obtaining a vulcanized laminated ball;
• and
• step l:
• surface finishing the vulcanized laminated ball and painting strips between any two adjacent ball covers to obtain the machine-laminated basketball.
