The objective of the present invention is to provide a stability ball case configured to store a stability ball therein and, especially, having a weight thereon to prevent the stored stability ball from rolling, thereby avoiding a safety accident that may happen when the stability ball rolls and drops, as well as storing the stability ball at a desired place in a safe and convenient manner. Particularly, another objective of the present invention is to provide a stability ball case configured such that a weight can be attached to and detached from a body constituting the case, whereby the weight can be separated from the body when the case is washed, or when the stability ball is carried, thereby enabling the stability ball case to be safely used and stored, as well as being conveniently used.

The rack -1- is moveable on wheels and has a locking cage enclosure -8-, the rack consists of a frame -2- with a front part -3- for moving it. On the frame -2-there are several vertical poles -4-, which have hoops -5-, with respective supporting arms -6-. The cage enclosure -8- consists of lateral stretches -10-, a rear front part - 11- and a top -12-, with its floor or base -8a- open, as well as its front part -8b which moves horizontally resting lower horizontal crossbars -9- on longitudinal side plates - 2a- of the frame -2-. The rack -1- may comprise a longitudinal crossbar -18-, wherein at the ends there are vertical poles -19- and -20- that support two longitudinal crossbars -21-, and on which hoops -22- are fixed by means of arms - 23-, further having supports -24- with wheels -25-. In the top part of the vertical foot - 20- there is a handlebar -26- and side bars -27-, parallel to each other. Its simplified cage -28- with feet -30- has the sides -28a-, top -28b- and rear front part -28c-closed, with only the front defined by vertical posts -29- being open. This simplified rack -1- presents a longitudinal crossbar -13-, provided with vertical poles -16- with hoops -17- and resting on supports -14- with wheels -15-, wherein the crossbar -13-has vertical poles -16- fixed to it and provided with hoops -17- for supporting the balls.

A controller (307) controls the position of an abrasive (462) . The abrasive is moved to a first desired position adjacent a ball (200). The ball is rotated while in contact with the abrasive. The abrasive abrades the outer surface of the ball and burrs (201,222,228,248,250) on the outer surface to remove the burrs. A sensor (473) may be used to sense the position and size of the burrs.

The invention relates to a carrying bag (1) comprising a first compartment (2) and a second compartment (3), separated from the first compartment (2). At least one of the first compartment (2) and second compartment (3) is configured to receive a sports product and contains an opening (5) arranged for exposing a portion of said product to the outside world. The first compartment (2) is arranged above said second compartment (3) in a carrying position of the carrying bag (1). The invention also relates to a method of manufacturing such a carrying bag (1).

In accordance with the principles of the present invention, improved shuttlecocks are provided by applying innovative packaging. The improved shuttlecocks are packaged in a suitably humid environment to prevent the moisture within the feathers of the shuttlecock from evaporating off. The packaging is substantially air tight and includes a humidity control mechanism (20). In one embodiment the package comprising a humidifying disc (26) in the shuttlecock packaging. The humidifying disc includes a plurality of openings (30) to allow for moisture to pass from the disc to the internal environment of the packaging and comprises a foam or sponge pad moistened with water and propylene glycol. The humidity within the packaging is held at a generally fixed level. In one embodiment, the relative humidity can be held at least about 20 %. In a further embodiment, the relative humidity can be held at about 50%.
