Abstract
A winding core capable of being made in relatively thick-walled configurations and yet capable of being readily collapsed into a flattened configuration for shipping or storage prior to use comprises a plurality of fibrous plies helically wound one atop another and adhered together to form a tube. The plies are arranged in two or more groups of two or more plies each. The plies of each group are adhered to one another over at least a substantial majority of their facing surfaces, but the adjacent groups are non-adhered to each other over at least a substantial majority of their facing surfaces.
