Abstract
A method for correlating negatives with processing envelopes in photographic laboratories, which comprises the steps of joining films together as they are extracted from their corresponding processing envelopes by a tape which has been progressively prenumbered in machine-readable code, reading the number printed on the tape portion used for each joint, and printing it in machine-readable code on the corresponding processing envelope.
Claims6
A method for correlating negatives with corresponding processing envelopes in photographic laboratories, which comprises:
- (i) joining films together after being extracted from corresponding processing envelopes by taping together the films with a tape portion which has been progressively prenumbered with machine-readable code,
- (ii) machine reading a number printed on the tape portion connecting the films, and
- (iii) printing the machine-read number in machine-readable code on the corresponding processing envelope.
An apparatus for correlating negatives with corresponding processing envelopes, which comprises:
- an arrival station at which processing envelopes arrive and wherein each processing envelope contains a film to be extracted from a relative spool,
- an extraction station at which a film is extracted from the relative spool,
- a joining station at which a tape portion of a tape which has been prenumbered in machine-readable code is applied between adjacent ends of two films in order to join the films together,
- a reader for reading the number printed on the tape portion, and
- a printer which uses an output signal of the reader in order to print in machine-readable code on a corresponding processing envelope from which the corresponding film was extracted a number which corresponds to the number read by the reader.
