Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
82 words
A MEDIUM FOR EFFECTING HEAT BONDING BETWEEN TWO SURFACES OF TEXTILE FABRIC MATERIAL COMPRISING A CARRIER SHEET ONE SIDE ONLY OF WHICH CARRIES LAYERS OF A HEAT BONDING SUBSTANCE AND OF A PRESSURE SENSITIVE ADHESIVE, SUCH LAYERS BEING ARRANGED THAT THEY BOTH PRESENT EXPOSED SURFACES IN A PLANE SUBSTANTIALLY PARALLEL TO THE CARRIER SHEET, THE SURFACE CARRYING THE HEAT BONDING SUBSTANCE BEING SUCH THAT THE HEAT BONDING SUBSTANCE IS READILY TRANSFERABLE THEREFROM TO THE SURFACE OF THE FABRIC MATERIAL TO BE BONDED.
Claim 2
Independent Claim
82 words
A MEDIUM FOR EFFECTING HEAT BONDING BETWEEN TWO SURFACES OF TEXTILE FABRIC MATERIAL COMPRISING A CARRIER SHEET ONE SIDE ONLY OF WHICH CARRIES LAYERS OF A HEAT BONDING SUBSTANCE AND OF A PRESSURE SENSITIVE ADHESIVE, SUCH LAYERS BEING ARRANGED THAT THEY BOTH PRESENT EXPOSED SURFACES IN A PLANE SUBSTANTIALLY PARALLEL TO THE CARRIER SHEET, THE SURFACE CARRYING THE HEAT BONDING SUBSTANCE BEING SUCH THAT THE HEAT BONDING SUBSTANCE IS READILY TRANSFERABLE THEREFROM TO THE SURFACE OF THE FABRIC MATERIAL TO BE BONDED.
Claim 3
Dependent Claim
26 words
A medium as claimed in claim 1 wherein the heat bonding substance is provided in discontinuous layers covering numerous substantially separate areas of the carrier sheet.
Claim 4
Dependent Claim
30 words
A medium as claimed in claim 1 wherein the area of the carrier sheet covered by the heat bonding substance is distinct from that covered by the pressure sensitive adhesive.
Claim 5
Dependent Claim
34 words
A medium as claimed in claim 2 wherein the pressure sensitive adhesive is also provided in discontinuous layers over numerous substantially separate areas of the carrier sheet not covered by the heat bonding substance.
Claim 6
Dependent Claim
19 words
A medium as claimed in claim 2 wherein the discontinuous layers referred to are in the form of dots.
Claim 7
Dependent Claim
25 words
A medium as claimed in claim 1 wherein the heat bonding substance is laterally separated from, and out of contact with, the pressure sensitive adhesive.
Claim 8
Dependent Claim
35 words
A medium as claimed in claim 1 wherein the heat bonding substance and the pressure sensitive adhesive are miscible with each other and have at least some contact with each other on the carrier sheet.
Claim 9
Dependent Claim
43 words
A medium as claimed in claim 1 wherein the surface of the said one side of the carrier sheet carrying the said layers is such that the said layers may readily be transferred therefrom to the surface of the material to be bonded.
Claim 10
Dependent Claim
26 words
A medium as claimed in claim 8 wherein the said one side of the carrier sheet has a coating of a release material under said layers.
Claim 11
Dependent Claim
83 words
A medium as claimed in claim 1 wherein the said one side of the carrier sheet is coated with a layer of the pressure sensitive adhesive and the heat bonding substance is applied over part of the layer of pressure sensitive adhesive, the pressure sensitive adhesive having such a strong affinity for the surface of the carrier sheet that it will remain adherent to the carrier sheet after transfer of the heat bonding substance to the surface of the material to be bonded.
Claim 12
Dependent Claim
22 words
A medium as claimed in claim 10 wherein the heat bonding substance and the pressure sensitive adhesive are miscible with each other.
Claim 13
Dependent Claim
26 words
A medium as claimed in claim 1 wherein at least the exposed surface of the pressure sensitive adhesive is covered by a readily removable protective sheet.
Claim 14
Dependent Claim
28 words
A medium as claimed in claim 12 wherein the other side of the carrier sheet constitutes the readily removable protective sheet when the carrier sheet is rolled up.
Claim 15
Dependent Claim
22 words
A medium as claimed in claim 13 wherein the said other side of the carrier sheet is coated with a release material.
Claim 16
Dependent Claim
11 words
A medium as in claim 1, wherein the carrier is paper.
Claim 17
Dependent Claim
16 words
A medium as in claim 1, wherein the heat bonding substance is a hot melt adhesive.
