Beschreibung
Zusammenfassung:	A cutting method and apparatus for closures of the "tethered" type are disclosed, in which a spindle that carries a closure is moved to a cutting device with one or more horizontal blades and at least one vertical or oblique blade. During cutting, the spindle rotates and the closure rolls on the cutting device. The spindle, which is fed several times to the cutting device carrying each time a different closure, comprises a portion made of a softer material than the blades so that during cutting the blades penetrate the material of the closure and then sink into the softest portion of the spindle. Feeding the spindle that carries the closure to the cutting device is coordinated with rotation of the spindle so that the vertical or oblique blade, each time that the spindle is fed to the cutting device, always meets the same zone of the softest portion of the spindle.
