Abstract
Abstract A drying apparatus which has a slit for ejecting an air jet, a mechanism for carrying a material so that the surface of the material being dried passes near the slit, and blade plates extending generally in parallel with the surface being dried in the direction of movement of the material by the slit, and in the direction opposite thereto.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
192 words
A drying apparatus comprising (1), at least one air supply means including (a) a slit for ejecting an air jet onto a material having a developed image on the surface to be dried, said slit being disposed transverse to the direction of movement of the material, has been inserted. and (b) two blade plates respectively extending from the sides of the slit generally across the width of and in parallel with the surface to be dried, and two pairs of feed rollers for carrying the surface to be dried past the said slit where each pair is disposed on opposite sides of said material and on opposite sides of said slit, the feed rollers on the same side of said material as said blade plates having flanges at both ends thereof which contact said material at the approximate edges thereof, to thereby prevent said material from contacting said blade plate so that said image cannot be damaged by contact with said blade plates, and where said blade plates contact the feed rollers which are on the same side of said material as themselves to prevent the passage of said air jet therebetween.
Claim 2
Dependent Claim
192 words
A drying apparatus comprising (1), at least one air supply means including (a) a slit for ejecting an air jet onto a material having a developed image on the surface to be dried, said slit being disposed transverse to the direction of movement of the material, has been inserted. and (b) two blade plates respectively extending from the sides of the slit generally across the width of and in parallel with the surface to be dried, and two pairs of feed rollers for carrying the surface to be dried past the said slit where each pair is disposed on opposite sides of said material and on opposite sides of said slit, the feed rollers on the same side of said material as said blade plates having flanges at both ends thereof which contact said material at the approximate edges thereof, to thereby prevent said material from contacting said blade plate so that said image cannot be damaged by contact with said blade plates, and where said blade plates contact the feed rollers which are on the same side of said material as themselves to prevent the passage of said air jet therebetween.
Claim 3
Dependent Claim
34 words
A drying apparatus as in claim 1 where said at least one air supplying means includes a rotatable flange disposed at each end of said slit to prevent said material from contacting said blade.
Claim 4
Dependent Claim
29 words
A drying apparatus as in claim 1 including a second air supply means symmetrically disposed on the side of said material opposite said at least one air supply means.
Claim 5
Dependent Claim
194 words
A drying apparatus comprising (1) at least one air supply means including (a) a slit for ejecting an air jet onto a material having a developed image on the surface to be dried, said slit being disposed transverse to the direction of movement of the material, has been inserted. and (b) at least one blade plate extending from one side of the slit generally across the width of and in parallel with the surface to be dried, and (2) at least one pair of feed rollers for cayying the surface to be dried past the said slit, said pair of feed rollers being disposed on opposite sides of said material and adjacent one side of said slit the feed roller on the same side of said material as said blade plate having flanges at both ends thereof which contact said material at the approximate edges thereof to thereby prevent said material from contacting said blade plate so that said image cannot be damaged by contact with said bladE plate, and where said air supplying means includes a rotatable flange disposed at each end of said slit to prevent said material from contacting said blade.
Claim 6
Dependent Claim
194 words
A drying apparatus comprising (1) at least one air supply means including (a) a slit for ejecting an air jet onto a material having a developed image on the surface to be dried, said slit being disposed transverse to the direction of movement of the material, has been inserted. and (b) at least one blade plate extending from one side of the slit generally across the width of and in parallel with the surface to be dried, and (2) at least one pair of feed rollers for cayying the surface to be dried past the said slit, said pair of feed rollers being disposed on opposite sides of said material and adjacent one side of said slit the feed roller on the same side of said material as said blade plate having flanges at both ends thereof which contact said material at the approximate edges thereof to thereby prevent said material from contacting said blade plate so that said image cannot be damaged by contact with said bladE plate, and where said air supplying means includes a rotatable flange disposed at each end of said slit to prevent said material from contacting said blade.
