Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
137 words
A device for drying film comprising: support means; transfer assembly means connected to said support means for delivering said film along a predetermined path; blower means for producing a continuous flow of air to dry said film; and at least one tube assembly connected to said support means and co-operating with said blower means for directing said flow of air to said film, said tube assembly including a circumferentially discontinuous metal cylinder having a continuous longitudinally directed slot and plastic sleeve means circumscribing and fixed on said cylinder, said sleeve means having a plurality of small apertures disposed in a longitudinal row overlying the slot in said cylinder for exposing portions of said slot whereby said flow of air is directed to said film, said apertures each having substantially equal dimensions longitudinally and transversely of said sleeve.
