What is happening is that the take-up spool is pulling the film through the camera,hence the ever increasing gaps as effective diameter of take-up spool gets bigger.What is supposed to happen is that the sprockets should pull the film through and the take-up spool does just that,helps coil the film.The only compensation mechanism present is that the take-up spool can slip on the wind-on shaft. A gear in the wind-on train has either stripped or come loose.Another possibility is that the sprocket assembly has worked loose.To test this, wind on and then see if you can rotate the sprocket assembly with gentle finger pressure.Only rotate in direction of film movement.The exposure interlock should prevent movement but if you can rotate the assembly,look for a loose or missing grub screw on the part in film chamber before you start pulling the camera down.Some cameras have the sprocket lock-screw very visible.My Praktica experience stops with a PrakticaMat in the very distant past.Good Luck Glenn |
