Abstract (en)

[origin: EP1225410A2] To form at least one insertion slit (6) in a collection tube (9), for the insertion of a flat tube in an air conditioning system, initially a cut is made with a saw in the required length (S1) and depth (d). In a second stage, a die punches the cut slit to form a passage (10), using a die with a greater width and/or length than the sawn slit.
