<p>A photographic still camera film system (10) uses a paper backed film strip (11) wound in a supply coil (20) with a leading end of the paper backing (12) attached to a take-up spindle (31) in a take-up container (30). A pair of axially interconnected end flanges (21) engage the ends of supply coil (20) with resilient material (22) carried on their inner faces. Resilient material (22) keeps the convolutions of supply coil (20) light tight. A rotatable hub supported on flanges (21) engages the inside of supply coil (20) to allow the supply coil to rotate relative to the flanges as the supply coil is unwound. The frictional engagement of resilient material (22) with the ends of supply coil (20) effectively prevents clock springing of the supply coil as it is unwound. A gear (46) arranged on take-up container (30) turns take-up spindle (31) to advance paper backed film strip (11) from supply coil (20) to take-up container (30). </p> |
