Controlled dispensing roll
This invention relates to paper rolls for sanitary or home use intended to operate in conjunction with a dispensing system. According to one essential feature of the invention, the roll includes internally a means intended to brake its unwinding. Thus, the consumption of paper may be controlled.
1. A paper roll for operation in conjunction with a dispensing system, comprising braking means internal of said roll arranged to brake unwinding of said roll wherein said braking means comprises at least one layer of adhesive material deposited on at least one side of the roll covering at least 15% of a surface of said at least one side.
2. The roll as claimed in claim 1 , wherein said at least one layer is deposited by printing.
3. The roll as claimed in claim 2 , wherein the at least one layer of adhesive material is deposited according to a regular pattern of points.
4. The roll as claimed in 2 , wherein the at least one layer of adhesive material is deposited according to a continuous pattern.
5. The roll as claimed in claim 2 , wherein the at least one layer of adhesive material is deposited according to a pattern comprising point zones and continuous zones.
6. The roll as claimed in claim 2 , wherein said at least one layer is deposited by pad printing.
7. The roll as claimed in claim 6 , wherein the at least one layer of adhesive material is deposited according to a pattern comprising point zones and continuous zones.
8. The roll as claimed in claim 6 , wherein the at least one layer of adhesive material is deposited according to a continuous pattern.
9. The roll as claimed in claim 6 , wherein the at least one layer of adhesive material is deposited according to a regular pattern of points.
10. A manufacturing process for a paper roll comprising forming the roll, applying at least one layer of adhesive material to at least one side of said roll in such a way that said at least one layer covers at least 15% of the area said at least one side of said roll and partially penetrates interiorly of a winding of the roll.
11. The process as claimed in claim 10 wherein the adhesive material is an aqueous compound.
12. The process as claimed in claim 10 , further comprising depositing said at least one layer by printing.
13. The process as claimed in claim 12 wherein the adhesive material is an aqueous compound.
