ABSTRACT:
A stopping device for an eyelet button holing machine provides a stopper arm which plunges into a recess portion of a stopper cam positioned coaxial to the main shaft. To absorb the stopping impulse, extra wheel cams are provided coaxial to the main shaft which induce the stopper arm to be inclined such that its position causes a clutch pulley to contact with a low speed pulley and then the stopper arm plunges into the recess portion of the stopper cam. Thus, the machine is stopped in two steps and the stopping impulse force is effectively alleviated.
