ABSTRACT:
The trailing end of a web of photosensitive material which is being unwound from a core in a cassette is connected to the core by an elongated strip. A monitoring device is placed adjacent the path of movement of the web from the core to the nip of two advancing rolls, and the monitoring device is activated as soon as it detects the strip. The motor for the advancing rolls is driven for an interval of time and at a speed such that, when the monitoring device detects the trailing end of the strip, the web is advanced through a predetermined distance to locate its trailing end at a splicing station where the trailing end of the web is to be spliced with the leader of a next-following web.
