Abstract (en)
[origin: EP2163671A1] The invention relates to a buttonholing machine (1). The buttonholing machine (1) includes stress detecting means (20) for detecting a stress (Ãn) applied to a knife (11) when forming a buttonhole, cumulating means (20) for cumulating, each time the buttonhole is formed, the stress (Ãn) detected by the stress detecting means (20) to calculate a cumulated stress (£Ãn), storing means (24) for storing a threshold stress (Ãa) that causes a wear-out or a breakage of the knife (11), and informing means (66) for informing a user of a replacement of the knife (11). When the cumulated stress (£Ãn) reaches the threshold stress (Ãa) or before the cumulated stress (£Ãn) reaches the threshold stress (Ãa), the control means (20) controls the informing means (66) to inform the user of the replacement of the knife (11).
