Abstract

A receptacle for a consumable material, such as a wire spool (2), to be loaded into a machine, such as a wire tying machine (18), comprises first and second indicating means (6, 12) for identifying the receptacle, wherein one of the indicating means (6) is separable from the receptacle.

Claims

1. A wire tying machine for receiving a wire spool, the machine comprising first and second detectors for detecting first and second identifications provided by first and second indicators on the spool, wherein the first and second detectors are so configured that the first detector detects the first indicator after the first indicator is separated from the spool, wherein the wire tying machine comprises an aperture arranged to receive the first indicator, and wherein the first detector is configured such that the first detector detects the first indicator when it is placed into the aperture.

2. A wire tying machine as claimed in claim 1 configured to render one of the indicators ineffective when a predetermined condition is met.

3. A wire tying machine as claimed in claim 2, wherein said predetermined condition comprises removal of the spool from the machine.

4. A wire tying machine as claimed in claim 2, wherein said predetermined condition comprises the spool being empty.

5. A wire tying machine as claimed in claim 1 configured to prevent operation if both indicators are not detected or if the first and second identifications provided by the first and second indicators do not correspond to the same spool.

6. A wire tying machine as claimed in claim 1, wherein the first and second identifications provided by the first and second indicators are different.

7. A wire tying machine as claimed in claim 1 wherein the first and second identifications are related by a predetermined algorithm.

8. A wire tying machine as claimed in claim 1, wherein at least one of the indicators on the spool provides a radio frequency identification.

9. A wire tying machine as claimed in any claim 1, wherein the separable indicator(s) is provided on a tab which is connected to the rest of the spool by a line of weakness.
