A spin trimming machine for trimming the necks of objects that have a dome molded above the trim line of the object. The machine is capable of positioning the object being trimmed in a predetermined orientation with respect to its starting orientation. This is carried out by the adjustment of the position and angle of the knife, which adjustment can be carried out while the trimming machine is operating. Preferably, the trimmed objects drop onto a conveyor belt which is porous and a vacuum manifold draws air through the conveyor belt at the point where the object is separated from the dome which holds it.
