- the sum S DH (h) + DC (h) can be compared with a predetermined deviation in the fifth step S5, a signal being output in the sixth step S6 if this comparison fulfills a predetermined criterion.
- the data read out in the third step S3 and / or that in the fourth step can suitably be used S4 recorded data also include the sum S DH (h) + DC (h).
- the sum S DH (h) + DC (h) is particularly advantageous for checking whether there is a criterion for the comparison V with the predetermined deviation, after any number in this way
- the inventive method can be used.
- the data recorded in step S4 can be recorded in a suitable manner in each case with assignment to a device E (n).
- the recorded data of a device E (n) namely n, X (n), H (n) and / or DC (h) and / or DH (h) and / or S DC (h) and / or S DH (h) and / or S DH (h) + DC (h) are stored in tabular form in corresponding rows and columns.
- 4B shows an example of data stored in a table that can be called up.
- a method according to the invention can also suitably have a further step in which the crimpings C, namely the number #C (n) and the number #C (n) carried out after the device E (n) has a crimp height H (n) ) is recorded together with the above recorded data, after which the data read out in step S3 may also include the number #C (n).
- step S6 in addition to a predetermined criterion and / or the sum S DH (h) + DC (h) the number #C (n) and / or their sum S # 0 (h), according to which, in the case of a device E (n) of a crimp height (n), an estimate of an expected suitability of the pressing elements for a number of crimpings to be carried out
