Abstract
Abstract A packaged adhesive laminate is formed by rolling up a laminate adhesive sheet or other material on a cylindrical core, securing a sheet of heat sealable material to the end of the laminate sheet and wrapping the heat sealable sheet around the rooled up laminate, cutting the rolls of material into individual rolls, positioning plastic end caps on each side of the individual rolls, and heat sealing the end caps to the heat sealable material. The end caps have lip portions which overlie the heat sealable wrapping. The invention also concerns a novel method fopackaging adhesive laminates or the like.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
85 words
A method of packaging a sheet material which comprises the steps of rolling up a sheet of the material to form a cylindrical roll, wrapping at least one layer of a heat sealable material in sheet form around the cylindrical surface of the roll, positioning preformed plastic caps at each end of the roll, each cap having a lip portion which overlies the edges of the heat sealable material, and sealing the end caps to the heat sealable material wrapping by the application of heat.
Claim 2
Independent Claim
85 words
A method of packaging a sheet material which comprises the steps of rolling up a sheet of the material to form a cylindrical roll, wrapping at least one layer of a heat sealable material in sheet form around the cylindrical surface of the roll, positioning preformed plastic caps at each end of the roll, each cap having a lip portion which overlies the edges of the heat sealable material, and sealing the end caps to the heat sealable material wrapping by the application of heat.
Claim 3
Dependent Claim
51 words
The method according to claim 1 further including the step of cutting the roll and heat sealable material wrapping diametrically to form a plurality of narrower rolls and positioning end caps on each end of each of the narrower rolls prior to sealing the end caps to the heat sealable material.
Claim 4
Dependent Claim
44 words
The method according to claim 1 wherein the sheet material is an adhesive laminate and wherein one end of the heat sealable material is secured to the outer end of the adhesive laminate prior to wrapping the heat sealable material around the cylindrical surface.
Claim 5
Dependent Claim
38 words
The method according to claim 1 wherein the sealing of the end caps to the heat sealable material is effected by forcing a bead of heated heat sealable material between the end cap and the heat sealable material.
Claim 6
Dependent Claim
31 words
The method according to claim 1 wherein the heat sealable material is attached to the trailing edge of the sheet material prior to wrapping the heat sealable material about the roll.
Claim 7
Dependent Claim
61 words
A package for a roll of sheet material comprising: a heat sealable material wrapping covering the outer cylindrical surface of the roll, and a plastic end cap at each end of the roll, each cap having a lip portion which overlies the edge of the heat sealable material wrapping and which is bonded to the wrapping by a heat sealed bond.
Claim 8
Dependent Claim
61 words
A package for a roll of sheet material comprising: a heat sealable material wrapping covering the outer cylindrical surface of the roll, and a plastic end cap at each end of the roll, each cap having a lip portion which overlies the edge of the heat sealable material wrapping and which is bonded to the wrapping by a heat sealed bond.
Claim 9
Dependent Claim
30 words
The package according to claim 6 wherein the sheet material is an adhesive laminate and wherein the heat sealable material is secured to the outer end of the adhesive laminate.
Claim 10
Dependent Claim
26 words
The package according to claim 6 wherein the heat sealable material is wrapped around the roll a plurality of times to provide multiple layers of wrapping.
Claim 11
Dependent Claim
32 words
The package according to claim 6 further including a bead of plastic material extending circumferentially around the roll and being bonded to both the wrapping and the flange of the end cap.
Claim 12
Dependent Claim
36 words
The method according to claim 1 including the step of sealing the end caps to the heat sealable material by beads of heated plastic material deposited to secure the end caps to the heat sealable material.
