Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
182 words
A method of packaging a preselected number of coins in a machine having at least one pair of heating sealing jaws with at least one jaw of said pair of jaws having an electric heater comprising the steps of: forming a sheet of thermoplastic material into a tube, supplying a first electrical potential to said electric heater to maintain said jaw at a preselected low temperature, flat pressing said tube and at substantially the same time interrupting said first electrical potential and supplying a second higher electrical potential to said electric heater to momentarily raise the temperature of said jaw to form a first transverse seal, stopping the supply of said second electrical potential and supplying said first electrical potential to said electric heater, supplying a predetermined number of coins into said tube above said first transverse seal, bringing said jaws together above said coins interrupting said first electrical potential and supplying said second electrical potential to said electric heater to form a second seal above said coins to form a pouch of coins and sever said formed pouch from said tube.
Claim 2
Independent Claim
182 words
A method of packaging a preselected number of coins in a machine having at least one pair of heating sealing jaws with at least one jaw of said pair of jaws having an electric heater comprising the steps of: forming a sheet of thermoplastic material into a tube, supplying a first electrical potential to said electric heater to maintain said jaw at a preselected low temperature, flat pressing said tube and at substantially the same time interrupting said first electrical potential and supplying a second higher electrical potential to said electric heater to momentarily raise the temperature of said jaw to form a first transverse seal, stopping the supply of said second electrical potential and supplying said first electrical potential to said electric heater, supplying a predetermined number of coins into said tube above said first transverse seal, bringing said jaws together above said coins interrupting said first electrical potential and supplying said second electrical potential to said electric heater to form a second seal above said coins to form a pouch of coins and sever said formed pouch from said tube.
Claim 3
Dependent Claim
14 words
The method of claim 1 wherein the high heat supplied is impulse electrical heat.
Claim 4
Dependent Claim
15 words
The method of claim 1 wherein the overlapped edges of said tube are sealed together.
Claim 5
Dependent Claim
21 words
The method of claim 3 wherein the overlapped edges of said tube are heat sealed simultaneously with said second transverse seal.
Claim 6
Dependent Claim
20 words
The method of claim 4 wherein high impulse heat is supplied to heat seal the overlapped edges of said tube.
