Volleyball (ball) has the following dimensions; a circumference of 65-67cm, inner pressure of 0.30-0.325kg/cm2 and weighs 260-280g. The ball is spherical in shape and consists of eighteen panels that are rectangular in shape usually arranged in six sections that are identical with three panels in each section.
Volleyballs are made of either synthetic or genuine leather that are usually wrapped around a specific material commonly known as rubber. In fact history of the volleyball is also interesting to know.
The ball used to play different games of volleyball such as
All these balls have different characteristics.
The beach volleyball has a circumference of 66-68cm, a mass of 260-280g and an internal pressure of 0.175-0.225 pa while the youth’s indoor ball has a circumference of 63-65cm, a mass of 260-280g and an internal pressure of 0.3pa.
Manufacturing the volleyball requires some distinct steps that have to be adhered to in order to come up with the required ball in terms of its shape, size and dimensions.
Step 1: Manufacturing of the hollow body
The hollow body of the ball has to be constructed has to be made before anything else; it is made in such a way that strips of clothes are overlapped together on a body that is spherical and hollow. The main function of the hollow spherical bag is to provide the required body bag. The spherical hollow body is usually constructed using material that is brittle.
The next step entails cutting a certain section of the body bag that has to be predetermined in order to come up with a thereon opening. When the opening has been made, the hollow body in the body bag that is spherical in shape usually collapses and the end result is that the body bag is split into several pieces.
The collapsed pieces in the body bag are taken out via the opening that was initially made; through the same opening, a tube that has a valve is inserted into the body bag.
At this point, the edges are usually turned up, the edges are therefore stuck to the base of the inserted valve and the manufacturers have to ensure that the edges are well fitted.
Rubber ribbons are then stuck in areas that correspond to the cloth stripping that were initially made; sticking the rubber ribbons on the body bag is carefully done so that the spherical shape of the ball is maintained.
Leather sheets are then stuck on the on the rubber layer to form the outer layer of the ball. The final stage is to ensure that the correct number of rectangular panels has been made and that they are also arranged accordingly.
The tube is usually coated with a lubricant for better adherence to the inner surface of the body bag; the other reason is to allow for the desired feel when handling the ball.
The volleyball ball life span depends on the manner in which it is used; if used frequently then it will not last for a long period of time; if used occasionally then chances are that it will serve you for a couple of years.
