Abstract
An apparatus for applying a stripe to the surface of a continuous strip of film material. The film is drawn from a roll of film wound on a supply reel and through a striping station where a striping material is applied to a predetermined zone on the upper surface of the film. Next, the film is drawn around a plurality of drying rollers which are positioned to form a generally rectangular, inwardly spiraling drying path. The film with the dried striping zone is collected on a take-up reel which is motor driven in co-operation with a drawing roller. The drawing roller draws the film from the supply roller, through the striping station and around the drying path.
Claims9
An apparatus for applying a stripe to a surface of a continuous strip of photographic film, comprising:
- a. means for storing the unstriped photographic film, said storage means including a film strip tensioning means, a rotatably mounted supply reel shaft for receiving a roll of unstriped film wound on a reel and a friction disc attached to said supply reel shaft and cooperating with a fixedly mounted friction plate to prevent overrunning of the reel shaft and the reel;
- b. means for applying striping material to a predetermined zone on the surface of the film as the film is drawn therethrough, said striping means including a drive wheel rotatably mounted and having a peripheral surface in driven contact with the film surface and a striping wheel rotatably mounted in driven relationship with said drive wheel and having a peripheral surface in contact with a predetermined zone of said film surface for applying a liquid striping material thereto;
- c. means for defining an inwardly spiraling drying path for the striped film without engaging the predetermined surface of the film;
- d. means for collecting the dried striped film;
- and
- e. means for drawing the film from said storage means, through said striping means and said drying path defining means, and to said collecting means, said drawing means including a rotatably mounted drawing roller having a peripheral surface for engagement with the film surface, means for driving said drawing roller, and a pair of flanged rollers rotatably mounted for guiding the film surface into contact with a predetermined portion of said peripheral surface of said drawing roller.
