Abstract
Abstract An apparatus for continuously manufacturing chip boards and the like by pressing particles mixed with binders between a pressing roller and an endless steel or steel mesh belt by calibrating rollers. Two spaced rollers are provided for the belt to travel around, one of these rollers serving as the pressing roller. These two rollers are relatively large in diameter and are relatively widely spaced so that a large manufacturing space is obtained inside of the belt path between the rollers. A forming station for supplying particles and binders to the belt, as well as a cutting station for cutting the pressed boards, and a transporting station for transporting the finished and cut boards from the belt area, are situated within the manufacturing space between the rollers. Alternatively, a coiling station for coiling very thin finished lengths of board could be provided in the manufacturing space.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
144 words
Apparatus for the continuous manufacture of boards, particularly chip boards made from loose particles mixed with binders; said apparatus comprising: a drivable endless tensionable belt, first and second relatively large diameter rollers for guiding the belt in a path around said rollers, said first and second rollers being spaced from one another such that a manufacturing space is formed between the first and second rollers inside of the path of the belt and delimited by said belt, a pouring station arranged in said manufacturing space for supplying loose particles and binders to the belt on the side facing said manufacturing space, calibrating rolls for pressing the belt against the loose particles and binders as the belt passes over around said first roller, and heating means for heating the loose particles and binders as they are being pressed between the belt and said first roller.
Claim 2
Dependent Claim
144 words
Apparatus for the continuous manufacture of boards, particularly chip boards made from loose particles mixed with binders; said apparatus comprising: a drivable endless tensionable belt, first and second relatively large diameter rollers for guiding the belt in a path around said rollers, said first and second rollers being spaced from one another such that a manufacturing space is formed between the first and second rollers inside of the path of the belt and delimited by said belt, a pouring station arranged in said manufacturing space for supplying loose particles and binders to the belt on the side facing said manufacturing space, calibrating rolls for pressing the belt against the loose particles and binders as the belt passes over around said first roller, and heating means for heating the loose particles and binders as they are being pressed between the belt and said first roller.
