Abstract
Abstract A method for press-bonding a laminated assembly of a sheet material (3) and a plastic film (2), which comprises providing on at least the peripheral portion of the sheet material and/or the plastic film a primer layer capable of adhering the sheet material and the plastic film at room temperature, stacking the sheet material and the plastic film to form a laminated assembly, evacuating a first vacuum compartment (20) defined by the sheet material and the plastic film to a vacuumed condition and at the same time, evacuating a second vacuum compartmens (10) enclosing at least the plastic film side of the first compartment, to a vacuumed condition, and then introducing atmospheric air into the second vacuum compartment to release it from the vacuumed condition and thereby to press-bond the plastic film to the sheet material.

Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
126 words
A method for press-bonding a laminated assembly of a sheet material and a plastic film, which comprises providing on at least the peripheral portion of the sheet material and/or the plastic film a printer layer capable of adhering the sheet material and the plastic film at room temperature, stacking the sheet material and the plastic film to form a laminated assembly, evacuating a first vacuum compartment defined by the sheet material and the plastic film to a vacuumed condition and at the same time, evacuating a second vacuum compartment enclosing at least the plastic film side of the first compartment, to a vacuumed condition, and then releasing the second vacuum compartment from the vacuumed condition and thereby to press-bond the plastic film to the sheet material.
Claim 2
Independent Claim
126 words
A method for press-bonding a laminated assembly of a sheet material and a plastic film, which comprises providing on at least the peripheral portion of the sheet material and/or the plastic film a printer layer capable of adhering the sheet material and the plastic film at room temperature, stacking the sheet material and the plastic film to form a laminated assembly, evacuating a first vacuum compartment defined by the sheet material and the plastic film to a vacuumed condition and at the same time, evacuating a second vacuum compartment enclosing at least the plastic film side of the first compartment, to a vacuumed condition, and then releasing the second vacuum compartment from the vacuumed condition and thereby to press-bond the plastic film to the sheet material.
Claim 3
Dependent Claim
14 words
The method according to Claim 1, wherein the plastic film has a self-healing property.
Claim 4
Dependent Claim
14 words
The method according to Claim 1, wherein the sheet material is a glass sheet.
Claim 5
Dependent Claim
29 words
The method according to Claim 1, wherein the plastic film has embosses with a depth of from 0.1 to 5 µ m on the side facing the sheet material.
Claim 6
Dependent Claim
26 words
The method according to Claim 1, wherein the primer layer is a primer capable of strengthening the adhesive force along the periphery of the plastic film.
Claim 7
Independent Claim
137 words
A method for press-bonding a laminated assembly of a sheet material and a plastic film, which comprises providing on at least the peripheral portion of the sheet material and/or the plastic film a primer layer capable of adhering the sheet material and the plastic film at room temperature, stacking the sheet material and the plastic film to form a laminated assembly, placing the laminated assembly in a first vacuum compartment defined by a cover film, evacuating the first vacuum compartment to a vacuumed condition and at the same time, evacuating a second vacuum compartment enclosing the first vacuum compartment, to a vacuumed condition, and then releasing the second vacuum compartment from the vacuumed condition and thereby to press the cover film to the laminated assembly surface so that the plastic film is press-bonded to the sheet material.
Claim 8
Independent Claim
137 words
A method for press-bonding a laminated assembly of a sheet material and a plastic film, which comprises providing on at least the peripheral portion of the sheet material and/or the plastic film a primer layer capable of adhering the sheet material and the plastic film at room temperature, stacking the sheet material and the plastic film to form a laminated assembly, placing the laminated assembly in a first vacuum compartment defined by a cover film, evacuating the first vacuum compartment to a vacuumed condition and at the same time, evacuating a second vacuum compartment enclosing the first vacuum compartment, to a vacuumed condition, and then releasing the second vacuum compartment from the vacuumed condition and thereby to press the cover film to the laminated assembly surface so that the plastic film is press-bonded to the sheet material.
