Abstract
A roll (54) of compressed materials (14) is provided which has a sleeve (50) formed around a rotatable mandrel (12). The sleeve (50) about which the materials (14) are rolled prevents the roll (54) from radially collapsing. The roll (54) may be removed from the mandrel (12) without tearing or telescoping of the material. In one embodiment the sleeve (50) is corrugated material (38). The corrugated material (38) is around the rotatable mandrel (12) prior to the compressible material (14) being wrapped around the sleeve (50). In another embodiment, the sleeve (58) comprises roll-packing material (32) laminated prior to being wound upon the mandrel (12).
Claims16
A roll of compressed material comprising:
- a sleeve made from a sheet of corrugated material having a pair of side edges, the corrugations of the sheet extending parallel the side edges, the sleeve having sufficient rigidity to prevent implosion of the roll of compressed material;
- roll packing material wrapped around the sleeve;
- and
- a compressible material wrapped around the sleeve, adjacent layers of compressible material being separated by said roll packing material.
A roll of compressed material comprising:
- a sleeve formed by wrapping roll packing material around a mandrel having retractable cleats, the cleats being expanded during the wrapping, the sleeve having sufficient rigidity to prevent implosion of the roll of compressed material, said sleeve having an overlapped portion and being secured to itself;
- and
- a compressible material wrapped around the sleeve.
A roll of compressed material comprising:
- a sleeve made of a sheet of corrugated material wrapped around a mandrel, the corrugations of the sheet of corrugated material extending perpendicular to a rotational axis of the mandrel, the sleeve having sufficient rigidity to prevent implosion of the roll of compressed material, said sleeve having an overlapped portion and being secured to itself;
- and
- a compressible material wrapped around the sleeve.
A roll of compressed material comprising:
- a sleeve having sufficient rigidity to prevent implosion of the roll of compressed material, said sleeve having multiple linear segments extending between cleats extending outwardly from a rotatable mandrel;
- and
- layers of compressible material wrapped around the sleeve.
A roll of compressed material comprising:
- a sleeve made from a sheet of corrugated material having a pair of side edges, the corrugations of the sheet extending parallel the side edges;
- and
- a compressible material wrapped around the sleeve, wherein adjacent layers of said compressible material are separated by roll packing material.
