Abstract
A cover belt conveyor for delivering bulk materials or piece goods includes, a basic belt (1) and a cover belt (2), wherein at least one of these belts (1, 2) is driven. A space for the delivery strand (4) is formed in the central area of these belts, and at least the cover belt (2) is pressed on by elastic support rollers (6). At least one of the two belts (1, 2) has, in the vicinity of its two edge areas, reinforcements (3) made in one piece with the belt, which laterally delimit the delivery strand (4). The support rollers (6) above the cover belt (2) and/or the support rollers (5) under the basic belt (1) are mounted elastically on support structures (10). In the exemplary embodiment, two short support rollers (6) each for the cover belt (2) are mounted elastically in a common bracket (8) by of rubber bearings (9). The rubber bearings (9) permit the support rollers (6 ) to move by an angle in parallel to the delivery direction and in parallel to the width of the belt.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
