A winding core with improved beam and hoop strength and diminished friability and method for manufacturing such a core are provided, the winding core comprising: an extruded wood fiber core member; and at least one preformed paper shell member having a split seam parallel to its major axis, the shell being adhered to an exterior surface of the extruded wood fiber core member and a secondary shell of wooden staves.

The invention relates to a system for sorting veneer sheets. The system comprises: an assembly section; a reject section; a feeding section arranged between the assembly section and the reject section; at least one detection device configured to scan a top surface of a topmost veneer sheet of a stack of veneer sheets to provide a plurality of successive scan lines images; at least two parallel transfer devices; and a control system. The control system is configured to provide a surface scan image from the plurality of successive scan lines images, determine one or more properties of the veneer sheet based on the surface scan image, and to control the at least two transfer devices to: move from an avoidance position to a pick-up position determined based on the surface scan image; pick up the topmost veneer sheet of the stack of veneer sheets; and transfer the picked-up veneer sheet to the assembly section in response to detecting that each of the determined one or more properties of the veneer sheet meets a respective predetermined criterion, or otherwise transfer the picked-up veneer sheet to the reject section. The invention relates also to a method for sorting veneer sheets.
