Conveying device, rolling body and conveying body

Abstract

A conveying device ( 100 ) according to the invention includes several conveying bodies ( 102 ), which roll on a guidance ( 101 ) via several rolls ( 3 ), wherein the rolls ( 3 ) are connected and mutually distanced by means of a flexible connecting body ( 9 ). The conveying bodies ( 102 ) include means ( 103; 104, 105 ) for mutual support, which prevent a movement of the conveying bodies ( 102 ) out of the guidance ( 101 ). A connecting body ( 9 ) and allocated rolls ( 3 ) form a roll body ( 2 ), wherein the roll body ( 2 ), on average, includes two or less than two rolls ( 3 ) per conveying body ( 102 ). A roll body ( 2 ) for a conveying device ( 100 ) includes a plurality of rolls ( 3 ) mutually connected in a linear manner, wherein the rolls ( 3 ) are mutually connected and distanced by means of a flexible and in particular also elastic connecting body ( 9 ). In a preferred embodiment, the connecting body ( 9 ) may be bent in at least two directions.

1 . A method for manufacturing a roll body with a plurality of rolls connected in linear manner, comprising the steps of:
 providing a flat material;   punching or cutting a connecting body from the flat material;   fitting roll rings into circular openings of the connecting body; and   snapping ball-shaped rolls into the roll rings.   
     
     
         2 . The method according to  claim 1 , wherein the roll rings comprise a circumferential groove on their outer edges by means of which they are fitted into circular openings of supporting regions of the connecting bodies. 
     
     
         3 . The method according to  claim 1 , wherein the roll rings are shaped in one piece of plastic and comprise an inner spherical surface, such that the ball-shaped rolls may be snapped into the roll rings. 
     
     
         4 . The method according to  claim 1 , wherein the connecting body is made of elastic flat material. 
     
     
         5 . The method according to  claim 2 , wherein the roll rings are shaped in one piece of plastic and comprise an inner spherical surface, such that the ball-shaped rolls may be snapped into the roll rings. 
     
     
         6 . The method according to  claim 2 , wherein the connecting body is made of elastic flat material. 
     
     
         7 . The method according to  claim 4 , wherein the connecting body is made of plastic or rubber or a blended fabric.
