Appl. No.:

09/589421

International Classification:

B65H 7514

US Classification:

2426101, 2426104, 156187, 156188, 156195

Abstract:

A tubular or ring-shaped core for winding pressure-sensitive tape has a paper board body and a release-coated outermost ply formed of a strip of polymer film having a release coating on its outer surface and a tacky adhesive layer on its inner surface. The strip is wound onto the core with one edge of the strip folded outwardly away from the core so as to expose the tacky adhesive layer on the folded edge. This folded edge is overlapped by the opposite edge of the strip, thereby placing the tacky adhesive layers on the two edges in contact with each other. A firm bond between the overlapping edges is achieved by the adhesive-to-adhesive contact. In a preferred embodiment, the overlapping edge of the strip overlaps slightly beyond the folded edge onto the unfolded outer surface of the strip. This unfolded portion is treated to promote adhesion of the overlapping edge thereto. Improved bonding of the polymer strip to the core, and improved conformance of the strip to irregularities in the core surface, are achieved in a preferred embodiment by heating the strip as it is being advanced to the core and applying tension to the heated strip to cause it to stretch as it is wound onto the core.

US Classification:

428 342, 428192, 229119, 229128, 229185

Abstract:

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.

International Classification:

B29C 53/82
B29C 33/38
B65H 75/02
B65H 75/10

Abstract:

An improved core for mounting on one or more core engaging elements such as a pair of chucks and a method of making an improved core are provided. The core is adapted to wind and unwind material thereon. The core may comprise a high coefficient of friction coating disposed on the inner surface of the core to improve the core-chuck interaction. The inner surface may be mechanically or chemically treated to improve core-chuck interaction.
