Abstract
Abstract An apparatus for forming a mat of comminuted material for the production of pressed board comprises a conveyor belt forming a transport path and a receiving surface for the mat and a plurality of spreading machines spaced apart along the band for depositing respective layers of comminuted material on the surface to form the mat. Each of the spreading machines has a feeder for feeding the comminuted material to a roller grate for depositing the comminuted material in a respective layer with longitudinal orientation of the comminuted material in the direction of movement of the belt. At least one of the machines is provided with a transverse orienter between the roller grate and the belt for imparting a transverse orientation to the comminuted material deposited on the belt. The orienter is shiftable between a position wherein it is interposed between the roller grate of the belt and a position in which it is offset from the interposed position.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
194 words
An apparatus for forming a mat of comminuted material for the production of pressed board, comprising: a conveyor belt forming a transport path and a receiving surface for said mat; and a plurality of spreading machines spaced apart along said band for depositing respective layers of comminuted material on said surface to form said mat, each of said spreading machines comprising: means for receiving said comminuted material, a feeder connected to said receiving means for displacing said comminuted material, and a roller grate oriented above said surface and receiving said comminuted material from said feeder for depositing said comminuted material in a respective layer with longitudinal orientation of the comminuted material in the direction of movement of said belt, at least one of said machines being provided with a transverse orienter between said roller grate and said belt for imparting a transverse orientation to the comminuted material deposited on said belt, and means for shifting said transverse orienter between a position wherein said transverse orienter is interposed between the roller grate of said one of said machines and said belt and a position in which said transverse orienter is offset from the interposed position.
Claim 2
Independent Claim
194 words
An apparatus for forming a mat of comminuted material for the production of pressed board, comprising: a conveyor belt forming a transport path and a receiving surface for said mat; and a plurality of spreading machines spaced apart along said band for depositing respective layers of comminuted material on said surface to form said mat, each of said spreading machines comprising: means for receiving said comminuted material, a feeder connected to said receiving means for displacing said comminuted material, and a roller grate oriented above said surface and receiving said comminuted material from said feeder for depositing said comminuted material in a respective layer with longitudinal orientation of the comminuted material in the direction of movement of said belt, at least one of said machines being provided with a transverse orienter between said roller grate and said belt for imparting a transverse orientation to the comminuted material deposited on said belt, and means for shifting said transverse orienter between a position wherein said transverse orienter is interposed between the roller grate of said one of said machines and said belt and a position in which said transverse orienter is offset from the interposed position.
Claim 3
Dependent Claim
25 words
The apparatus defined in claim 1 wherein said transverse orienter is a traveling grate in the form of a belt having transverse bars forming baffles.
Claim 4
Dependent Claim
50 words
The apparatus defined in claim 2 wherein said one of said machines has a pair of roller grates, each of which is provided with a respective one of said traveling grates forming a respective transverse orienter, said transverse orienters being selectively shiftable out of alignment with the respective roller grate.
Claim 5
Dependent Claim
23 words
The apparatus defined in claim 2, further comprising means for adjusting the height of the roller grate of said one of said machines.
Claim 6
Dependent Claim
23 words
The apparatus defined in claim 2, further comprising means for adjusting the height of the traveling grate of said one of said machines.
Claim 7
Dependent Claim
21 words
The apparatus defined in claim 2 wherein said roller grate of said one of said machines is inclined to said belt.
Claim 8
Dependent Claim
15 words
The apparatus defined in claim 2 wherein said traveling grate is inclined to said belt.
Claim 9
Dependent Claim
17 words
The apparatus defined in claim 2 wherein said roller grate comprises a multiplicity of interdigitating disk-shaped rollers.
Claim 10
Dependent Claim
25 words
The apparatus defined in claim 8 wherein said roller grate comprises a plurality of rollers having gaps between them, further comprising baffles in said gaps.
