The present invention relates generally to a ball, and more particularly, to a synthetic fiber ball that looks, feels, and sounds like a snowball.
Playing with snowballs is a childhood past time that many children that have the opportunity do. Unless there is snow on the ground, children, and adults for that matter, cannot play with snowballs. In addition, children must go outside to play with snowballs if snow is on the ground and weather conditions may make such ventures unhealthy. As such, a need exists for a way to play with a snowball like object without the need to have snow and venture outside in dangerous weather conditions.
A fiber ball is disclosed that looks like a snowball, feels like a snowball and sounds like a snowball when compressed. In addition, a method of manufacturing a fiber snowball is disclosed.
The invention is further elucidated in the following on the basis of an exemplary embodiment shown in the drawings.

Synthetic fibers are fibers that are generally created as the result of research to improve naturally occurring animal and plant fibers. In general, synthetic fibers are created by forcing, usually through extrusion, fiber forming materials through holes (called spinnerets) into the air, forming a bead. Synthetic fibers can also be made from synthesized polymers or small molecules. Non-synthetic fibers are fibers that are formed from animals (such as cotton) and plant fibers.

The next step in forming the balls 10 is a process of bundle cutting 40. In this step, a bundle cutting machine 34 is used to cut the fiber bundle strand 22 at a required length. The distance from the fastening fiber 12 to both cut ends 26 must be equal. In one form, the distance from the fastening fiber 12 to both cut ends 26 is about 2.5 inches. Equal distance makes the fiber ball 10 round after the shaping oven process is complete. Non-equal distance will result in non-round fiber balls. As a result of this step, a generally cylindrical shaped cut fiber bundle 28 is formed which is illustrated in
Once the generally cylindrical shaped cut fiber bundles 28 are formed, the next step in the process of creating the fiber balls 10 is shaping 50. At this step, a spinning oven 36 is used to shape the generally cylindrical shaped cut fiber bundles 28 into the fiber ball 10. This process is very critical to make the fiber ball 10 feel like a snowball and sound like a snowball. In one form, the spinning oven 36 is set up at 80° C. and the cut fiber bundles 28 are heated for about 10-12 minutes. In another form, the spinning oven 36 is set up at 100° C. and the cut fiber bundles are heated for about 8 minutes. In yet another form, the spinning oven 36 is set up at 120° C. and the cut fiber bundles are heated for about 6 minutes. The spinning oven 36 is also set at a predetermined spinning speed to properly form the fiber ball 10.
The temperature and timing is critical to make the fiber ball 10 at just the right size and hardness. If the temperature is set up to high or the timing is longer, then the fiber ball 10 will be too hard and will not remain in a good looking snowball type shape and will not feel like a snowball or sound like a snowball. If the temperature is set too low or the timing is too short, then the fiber ball 10 will come out too soft and will not remain in a good looking shape and cannot come back to a ball shape after impact. The spinning oven 36 must also continuously spin during the shaping process. During the shaping process, the cut fiber bundles 28 shrink to form the fiber ball 10.
Although embodiments of the invention have been described using specific terms, such description is for illustrative purposes only, and it is to be understood that changes and variations obvious to the skilled artisan are to be considered within the scope of the claims that follow and their equivalents.
