Magnetic stripe applicator for paper roll - has foil or glue brush to apply magnetic stripe to backing of photographic paper for automatic trimmer etc.

摘要

A magnetic stripe is applied to the back of photographic material so that it can be detected for automatic trimming etc. The sensitised material (1) is passed through rollers (3, 4) together with a foil roll material (2) carrying the magnetic stripe. Adhesive (2a) is applied to the material carrying the stripe and the material is passed through rollers (3, 4) together with the sensitised material (1). The magnetic stripe is detected (7) to control the automatic trimmer (5, 6). An alternative method is to apply the magnetic stripe in a glue base and apply it to the back of the sensitised material before passing over a dryer.
