Patent ID: 8272498

Claim:
A conveyor for conveying and overturning flat objects, such as piled-up sheaves of paper or printed materials, comprising: a first ring-wound belt ( 10 ) mounted on rollers, respectively an upstream roller ( 11 ) of the first belt ( 10 ) and a downstream roller ( 12 ) of the first belt ( 10 ), a second ring-wound belt ( 20 ) mounted on rollers, respectively an upstream roller ( 21 ) of the second belt ( 20 ) and a downstream roller ( 22 ) of the second belt ( 20 ), with an active branch ( 13 ) of the first belt ( 10 ) facing and in contact with a corresponding active branch ( 23 ) of the second belt ( 20 ), thus constituting an input section ( 30 ) between the upstream roller ( 11 ) of the first belt ( 10 ) and the upstream roller ( 21 ) of the second belt ( 20 ), and an output section ( 40 ) between the downstream roller ( 12 ) of the first belt ( 10 ) and the downstream roller ( 22 ) of the second belt ( 20 ), the first belt ( 10 ) and the second belt ( 20 ) being subjected to an axial torsion of 180°, in order to exchange the position of the first belt ( 10 ) and the second belt ( 20 ); the first belt ( 10 ) longitudinally staggered in relation to the second belt ( 20 ), so that the upstream roller ( 11 ) of the first belt ( 10 ) is staggered in relation to the corresponding upstream roller ( 21 ) of the second belt ( 20 ), and the downstream roller ( 22 ) of the second belt ( 20 ) is staggered in relation to the downstream roller ( 12 ) of the first belt ( 10 ); a support roller ( 14 ) contacting and horizontally supporting the first belt, which support roller ( 14 ) is arranged downstream of the upstream roller ( 21 ) of the second belt ( 20 ), defining a zone therebetween where the first belt and the second belt overlap, the support roller ( 14 ) maintaining the first belt ( 10 ) and the second belt ( 20 ) in a horizontal position from the input section ( 30 ) through the zone.
