<p>Disclosure is given for a rotary support device for use in performing work for articles while rotating the article. Further a method will be described of producing large rotary support devices for use with an article handling pallet, particularly for use in drawing pictures on clay jars or pots or in trimming or taking care of potted plants. The rotary support device be composed of an under (1) and an upper (2) ring including horizontal portions (11,21) for fastening the device. Ring walls (13,23) projecting upward and downward from the horizontal portions (11,21) being inclined either outward or inward with guide grooves (15,25) for a ball (4) bearing. Assembly will be done by pressing the rings (1,2) against each other with the balls (4) interposed there between by elastically deformation of these rings.</p> |
