Claim 2

A method for integrating a multiplicity of rolls of compressible material into a unitarily handleable multiple stack, which method comprises assembling a plurality of rolls in groups, the rolls of each group being substantially the same length and being assembled with a plurality of rolls in each of at least two layers superposed upon each other, with the axes of individual rolls of each layer overlying the axes of individual rolls of adjoining layers in common vertical planes and the rolls overlying each other being in contact with each other, assembling each multilayer group of rolls between a pair of contoured panels having grooves in which the adjoining opposite side portions of the assembly of rolls are received, establishing predetermined package dimensions in both directions transverse to the axes of the rolls by partially compressing the assembly of rolls between said contoured panels while restraining lateral spreading of the assembly of rolls between assembly forming walls having predetermined lateral dimension of the assembly, applying bindings to the assembled and partially compressed rolls of each group to form separate integrated multiple roll packages of predetermined dimensions in both directions transverse to the axes of the rolls, releasing the pressure after application of the binding, assembling a plurality of said packages in a stack with the package side surfaces in common planes at both sides of stack, and applying bindings to said stack, the stack bindings comprising shrinkable plastic sheet material, at least a portion of which bridges and is shrunk onto adjoining laterally exposed surfaces in said common planes at the sides of the stacked packages.

Claim 3

A method for integrating a multiplicity of rolls of compressible material into a unitarily handleable assembly, which method comprises assembling a plurality of rolls in groups each comprising a plurality of layers with a plurality of rolls in each layer, the rolls of each layer being in lateral contact with each other and the rolls of the layers having their axes superimposed in vertical planes and being in superimposed contact with each other, establishing predetermined package dimensions in both directions transverse to the axes of the rolls by partially compressing the assembled rolls of each group in one lateral direction while restraining spreading of said assembled rolls in another lateral direction, applying bindings to the assembled and compressed rolls of each group to form separate multiple roll packages each having the same lateral dimensions, assembling a plurality of said packages in a stack with lateral side surfaces of the rolls in common planes at the sides of the stack packages, and applying bindings to said stack, the stack bindings comprising heat shrinkable plastic sheet material, at least a portion of which bridges and is heat shrunk onto adjoining laterally exposed surfaces in said common planes at the sides of the stacked packages.

Claim 4

A method for integrating a multiplicity of rolls of compressible material into a unitarily handleable assembly, which method comprises assembling a plurality of rolls in groups each comprising a plurality of layers with a plurality of rolls in each layer, the rolls of each layer being in lateral contact with each other and the rolls of the layers having their axes superimposed in vertical planes and being in superimposed contact with each other, establishing predetermined package dimensions in both directions transverse to the axes of the rolls by partially compressing the assembled rolls of each group in one lateral direction while restraining spreading of said assembled rolls in another lateral direction, applying bindings to the assembled and compressed rolls of each group to form separate multiple roll packages each having the same lateral dimensions, assembling a plurality of said packages in a stack with lateral side surfaces of the rolls in common planes at the sides of the stack packages, and applying bindings to said stack, the stack bindings comprising heat shrinkable plastic sheet material, at least a portion of which bridges and is heat shrunk onto adjoining laterally exposed surfaces in said common planes at the sides of the stacked packages.

Claim 6

A method for integrating a multiplicity of generally cylindrical rolls of compressible material into a unitarily handleable assembly, which method comprises partially compressing multiple roll packages of said compressible rolls of compressible material, stacking at least two partially compressed multiple roll packages in superposed relation, said roll packages being of substantially the same lateral dimension, with laterally presented recesses adjoining and intervening between an upper roll of the lower package and a lower roll of the upper package, at least the lower of said roll packages having an external wrapping of heat shrinkable plastic sheet material, binding the packages together by placing heat shrinkable plastic sheet material around the assembly of stacked packages in position to laterally overlie the recesses between the upper part of the lower package and the lower part of the upper package, and heat shrinking plastic sheet material employed for binding the packages together and thereby cause the heat shrunk sheet material to conform to and engage surfaces of the packages adjoining said recesses.

Claim 7

A method for integrating a multiplicity of generally cylindrical rolls of compressible material into a unitarily handleable assembly, which method comprises partially compressing multiple roll packages of said compressible rolls of compressible material, stacking at least two partially compressed multiple roll packages in superposed relation, said roll packages being of substantially the same lateral dimension, with laterally presented recesses adjoining and intervening between an upper roll of the lower package and a lower roll of the upper package, at least the lower of said roll packages having an external wrapping of heat shrinkable plastic sheet material, binding the packages together by placing heat shrinkable plastic sheet material around the assembly of stacked packages in position to laterally overlie the recesses between the upper part of the lower package and the lower part of the upper package, and heat shrinking plastic sheet material employed for binding the packages together and thereby cause the heat shrunk sheet material to conform to and engage surfaces of the packages adjoining said recesses.

Claim 10

A method for integrating a multiplicity of rolls of compressible material into a unitarily handleable package, which method comprises assembling a plurality of rolls in a group, the rolls of the group being substantially the same length and being assembled with a plurality of rolls in each of at least two layers superposed upon each other, with the axes of individual rolls of each layer overlying the axes of individual rolls of adjoining layers in common vertical planes and the rolls overlying each other being in contact with each other, assembling the layers of rolls between a pair of contoured panels having grooves in which the adjoining opposite side portions of the assembly of rolls are received, establishing predetermined package dimensions in both directions transverse to the axes of the rolls by partially compressing the assembly of rolls between said contoured panels while restraining lateral spreading of the assembly of rolls between forming walls having the predetermined lateral dimension of the assembly, applying bindings to the assembled and partially compressed rolls of the group to form an integrated multiple roll package of predetermined dimensions in both directions transverse to the axes of the rolls and releasing the pressure after application of the bindings.

Claim 11

A method for integrating a multiplicity of rolls of compressible material into a unitarily handleable package, which method comprises assembling a plurality of rolls in a group, the rolls of the group being substantially the same length and being assembled with a plurality of rolls in each of at least two layers superposed upon each other, with the axes of individual rolls of each layer overlying the axes of individual rolls of adjoining layers in common vertical planes and the rolls overlying each other being in contact with each other, assembling the layers of rolls between a pair of contoured panels having grooves in which the adjoining opposite side portions of the assembly of rolls are received, establishing predetermined package dimensions in both directions transverse to the axes of the rolls by partially compressing the assembly of rolls between said contoured panels while restraining lateral spreading of the assembly of rolls between forming walls having the predetermined lateral dimension of the assembly, applying bindings to the assembled and partially compressed rolls of the group to form an integrated multiple roll package of predetermined dimensions in both directions transverse to the axes of the rolls and releasing the pressure after application of the bindings.
