A support for mounting a paperboard yarn core on a spindle assembly includes a proximal-end support member for supporting a proximal end of the core and engaging it in a substantially non-slip manner, and a distal-end support member for supporting a distal end of the core. The proximal-end support member is configured to be mounted on a hub of the spindle assembly. The support members locate the core substantially coaxially with respect to a rotational axis of the spindle assembly. The proximal-end support member is configured to automatically prevent or minimize slippage of the core with respect to the support member both in acceleration and deceleration or braking of the spindle assembly.

A biodegradable plant pot is formed from a paperboard-based blank wrapped about an axis and having a first longitudinal edge portion overlapping and adhered to an opposite second longitudinal edge portion of the blank so as to form an overlap seam. The blank is oriented with the machine direction of the paperboard running substantially parallel to the axis and the cross-machine direction running substantially circumferentially about the side wall, such that the machine direction of the paperboard runs lengthwise along the overlap seam. Cuts are formed in the side wall adjacent to and at circumferentially opposite sides of one end of the overlap seam, the cuts being confined to a localized region adjacent the one end of the overlap seam. The end of the overlap seam is graspable and pullable in a direction generally toward the opposite end of the overlap seam, the cuts facilitating the starting of tearing of the blank along the overlap seam such that the overlap seam is torn from the side wall from the bottom edge to the top edge thereof.

Biodegradable plant pot

A paper-based plant pot comprises a container formed from a sheet of paper-based material wrapped about an axis, opposite edge portions of the sheet being secured to each other, the container having a side wall that encircles the axis and a bottom wall formed by a plurality of bottom panels of the sheet folded inwardly from a lower edge of the side wall and engaging one another. The sheet comprises a paperboard substrate formed of natural cellulose fibers, an internal sizing composition incorporated into the paperboard substrate so as to render the paperboard substrate substantially resistant to saturation by liquid water, and a thermoplastic polymer layer on one of the major surfaces of the paperboard substrate. The thermoplastic polymer layer faces an interior of the container and forms an inner surface thereof for contact with soil or other growing medium placed in the container.

Paper-based plant pot, and blank for making same

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.

Collapsible winding core and method of making same

A concrete column forming tube and method of making same for receiving poured concrete column therein to produce a concrete column is characterized by a smooth inside coated surface in the forming tube to eliminate spiral seam lines and other undesirable characteristics on the outside surface of the formed concrete column. The tube is formed from spirally-wound plies of paper adhered together and has a centrifugally-cast epoxy resin coating sprayed onto the inside surface of the spirally-wound tube while the tube is rotating to produce a smooth inside coated surface on the forming tube.
