Abstract
Abstract A conveying apparatus for paper products in stream form having two parallel belt elements supported by rollers is made up of individual standardized self-contained prefabricated constructional elements which at least at a side lying in the product flow direction are couplable to a corresponding constructional unit in such a manner that only a single conveyor belt pair is provided which is supported by rollers or rolls and driven by a single drive unit, and at least one constructional unit is constructed for a deflection and/or turning of the product stream.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
114 words
A conveying apparatus for paper products wherein endless belts are guided so as to propagate the products, the apparatus having adjustable features to provide for guiding endless belts so as to turn the propagated products about the propagation axis, comprising a plurality of conveying assemblies, each assembly comprising a housing having two parallel, spaced-apart shafts attached thereto, and rotatable rollers on each shaft, spaced apart sufficiently to guide products therebetween; an elongate plate having a transverse curvature, and a plurality of transverse slots extending at least partially along said transverse curvature; and means for adjustably mounting each of said plurality of conveying assemblies to said elongate plate in predetermined positions along said transverse slots.
Claim 2
Dependent Claim
114 words
A conveying apparatus for paper products wherein endless belts are guided so as to propagate the products, the apparatus having adjustable features to provide for guiding endless belts so as to turn the propagated products about the propagation axis, comprising a plurality of conveying assemblies, each assembly comprising a housing having two parallel, spaced-apart shafts attached thereto, and rotatable rollers on each shaft, spaced apart sufficiently to guide products therebetween; an elongate plate having a transverse curvature, and a plurality of transverse slots extending at least partially along said transverse curvature; and means for adjustably mounting each of said plurality of conveying assemblies to said elongate plate in predetermined positions along said transverse slots.
Claim 3
Dependent Claim
26 words
The apparatus of claim 1, wherein said conveying assembly housings each further comprise an attachment surface shaped to conform to the curvature of the elongate plate.
Claim 4
Dependent Claim
32 words
The apparatus of claim 1, wherein said means for adjustably mounting further comprises a curved bracket having fasteners therethrough, said bracket being curved to conform to the curvature of the elongate plate.
Claim 5
Dependent Claim
27 words
The apparatus of claim 2, wherein said conveying assembly housings each further comprise an attachment surface shaped to conform to the concave curvature of the elongate plate.
Claim 6
Dependent Claim
46 words
The apparatus of claim 4, wherein said means for adjustably mounting further comprises a curved bracket having fasteners therethrough, said bracket being affixed against the convex surface of said elongate plate, and said fasteners extending through said transverse slots and attaching to said conveying assembly housing.
