Abstract
Abstract A machine for applying a portion of photosensitive film to at least one face of a flat plate having a surface area greater than said portion, starting from at least one reel (66) of said material, comprises, downstream of said reel (66), first means (73) for laterally trimming the photosensitive strip of material (66) to a width less than the width of the plate (4), intermediate means (21), (74) on which said film (66) thus trimmed rests and is retained, associated with means (37), (78) arranged to separate portions of strip (66) having a length less than the length of the plate (4), and means (26), (27) controlled by suitable control means (28), (29) and by suitable positioning means (33), (34), (36) such that the plate (4) receives the film (66) in the correct position, and further comprises subsequent laminating means (48) for fixing the film (66) to the plate (4).

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
110 words
A machine for applying a portion of photosensitive film to a flat support plate, of the type comprising at least one unwinding unit (65) for said film (66), and means (5), (19) for feeding said film (66) and said plate (4) between two pressure rollers (48), characterised by comprising, between the unwinding unit (65) and the pressure rollers (48), intermediate means constituted by a profiled cylindrical surface (21), (74) on which the film (66) slides, said means being associated with transverse cutting means (37), (38), and means (26), (27), (28), (29), (75), (76) for pressing the strip of film (66) on to the respective plate (4) adjacent to the cut.
Claim 2
Dependent Claim
110 words
A machine for applying a portion of photosensitive film to a flat support plate, of the type comprising at least one unwinding unit (65) for said film (66), and means (5), (19) for feeding said film (66) and said plate (4) between two pressure rollers (48), characterised by comprising, between the unwinding unit (65) and the pressure rollers (48), intermediate means constituted by a profiled cylindrical surface (21), (74) on which the film (66) slides, said means being associated with transverse cutting means (37), (38), and means (26), (27), (28), (29), (75), (76) for pressing the strip of film (66) on to the respective plate (4) adjacent to the cut.
Claim 3
Dependent Claim
49 words
A machine as claimed in claim 1, characterised in that said intermediate means are constituted by a perforated member (21), (74) associated with a chamber (24) subjected to suction, on said member (21), (74) the film (66) being able to slide while being retained thereon in an adhering position.
Claim 4
Dependent Claim
45 words
A machine as claimed in claim 2, characterised in that said perforated member is a cylinder (21) idly mounted on its shaft (25), and provided with slots (23) parallel to its axis (25) to act as backing blades in which the cutting means (37) slide.
Claim 5
Dependent Claim
32 words
A machine as claimed in claim 2, characterised in that said perforated member is a fixed cylindrical sector (75), of which a longitudinal edge (77) is associated with the cutting means (78).
Claim 6
Dependent Claim
87 words
A machine as claimed in claims 1, 2 and 3, characterised in that said perforated member (21) is mounted on a slide (26), (27) orthogonal to the path of travel (A) of the plate (4) intended to receive the film (66), and is associated with means (28), (29) arranged to cause it to slide on said slide (26), (27) in order to press it against said plate (4) in such a manner as to cause the strip of film (66) to adhere thereto adjacent to the cut.
Claim 7
Dependent Claim
74 words
A machine as claimed in claims 1, 2 and 4, characterised in that adjacent to one of the flat walls of the cylindrical sector (74) there are provided slide passageways for a pad, means (76) for causing a pad to slide therein, and a slidable pad (75) arranged to press the film (66) against the underlying plate (4) in order to cause the strip of film (66) to adhere thereto adjacent to the cut.
Claim 8
Dependent Claim
29 words
A machine as claimed in claims 1, 2, 4 and 6, characterised in that a backing blade (77) for the cutting means (78) is associated with said pad (75).
Claim 9
Dependent Claim
61 words
A machine as claimed in claim 1, characterised in that said cutting means (37), (78) comprise a transverse slider (38), (79) driven with to-and-fro motion, and on which there is fixed a blade (43), (78) associated with an idle roller (44) which presses the strip in order to lock it against the edge of the backing blade (23) during the cutting.
Claim 10
Dependent Claim
41 words
A machine as claimed in claim 1, characterised in that the common plane tangential to the intermediate means (21), (74) and the pressure roller (48) disposed on the same side of the plate (4) cuts the plane of said plate (4).
