Abstract

Abstract An adhesive printing blanket including rubber or rubber-like material. The printing blanket may also be provided with reinforcing inserts. A foil-like protective layer covers the adhesive layer of the printing blanket. The protective layer, which is elastically flexible, is removed by pulling off prior to the adhesive mounting of the printing blanket. The protective layer is under a tensile stress to preclude creasing during rolling up of the printing blanket into a roll and during subsequent spreading out of the printing blanket into a plane.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 131 words
In combination: an adhesive printing blanket made for application subsequently on a printing cylinder and comprising a first section having a longitudinal direction and an adhesive layer on said first section; and a foil-like elastically flexible protective layer removably connected to that side of said adhesive layer which is remote from said first section, said protective layer being under tensile stress in the longitudinal direction and being provided for transporting as well as storage thereof after production subject to removal of said protective layer prior to application of said first section of the adhesive printing blanket upon the printing cylinder, said protective layer having absolutely no direct influence upon the printing blanket during subsequent printing operation itself though protecting the printing blanket in undamaged and undeformed condition for actual use thereof.
Claim 2
Dependent Claim 131 words
In combination: an adhesive printing blanket made for application subsequently on a printing cylinder and comprising a first section having a longitudinal direction and an adhesive layer on said first section; and a foil-like elastically flexible protective layer removably connected to that side of said adhesive layer which is remote from said first section, said protective layer being under tensile stress in the longitudinal direction and being provided for transporting as well as storage thereof after production subject to removal of said protective layer prior to application of said first section of the adhesive printing blanket upon the printing cylinder, said protective layer having absolutely no direct influence upon the printing blanket during subsequent printing operation itself though protecting the printing blanket in undamaged and undeformed condition for actual use thereof.
Claim 3
Dependent Claim 16 words
A combination according to claim 1, in which said first section is made of elastomeric material.
Claim 4
Dependent Claim 45 words
A combination according to claim 1, in which said first section comprises a first elastomeric layer, a second elastomeric layer, and a reinforcing insert interposed between and connected to said first and second layer, said adhesive layer being connected to one of said elastomeric layers.
Claim 5
Independent Claim 181 words
A method of making an adhesive printing blanket made for application subsequently on a printing cylinder and comprising a first section having a longitudinal direction and an adhesive layer on said first section; and a foil-like elastically flexible protective layer removable connected to that side of said adhesive layer which is remote from said first section, said protective layer being under tensile stress in the longitudinal direction and being provided for transporting as well as storage thereof after production subject to removal of said protective layer prior to application of said first section of the adhesive printing blanket upon the printing cylinder, said protective layer having absolutely no direct influence upon the printing blanket during subsequent printing operation itself though protecting the printing blanket in undamaged and undeformed condition for actual use thereof, which includes the step of generating elastic tension in said protective layer by rolling said protective layer together with said printing blanket on a cylindrical mantle in such a way that said protective layer first faces said mantle and then, by rolling up said printing blanket, faces outwardly.
Claim 6
Independent Claim 181 words
A method of making an adhesive printing blanket made for application subsequently on a printing cylinder and comprising a first section having a longitudinal direction and an adhesive layer on said first section; and a foil-like elastically flexible protective layer removable connected to that side of said adhesive layer which is remote from said first section, said protective layer being under tensile stress in the longitudinal direction and being provided for transporting as well as storage thereof after production subject to removal of said protective layer prior to application of said first section of the adhesive printing blanket upon the printing cylinder, said protective layer having absolutely no direct influence upon the printing blanket during subsequent printing operation itself though protecting the printing blanket in undamaged and undeformed condition for actual use thereof, which includes the step of generating elastic tension in said protective layer by rolling said protective layer together with said printing blanket on a cylindrical mantle in such a way that said protective layer first faces said mantle and then, by rolling up said printing blanket, faces outwardly.
