Pilgrim steps systems are made for simultaneous tube movements in parallel. They are particularly interesting on given processes (where several operations have to be carried out quickly in a given reduced space). For instance, when tube ends have to be chamfered. Operations can be divided following the order :
– 1st end chamfering / A
– 2nd end chamfering / B
– Blowing / C
In this case, pilgrim steps make 4 tubes pass from one operation to the following one: simultaneously, one tube goes from entry storage to operation /A, one tube goes from/A to /B, one tube goes from /B to /C and one tube goes from /C to the next production step.
