CUTTING APPARATUS AND METHOD

摘要

In a cutting apparatus a rotating carousel (3) conveys caps made of plastics (2) to a fixed blade (6) having the shape of a circumference arc. The caps are rotated about themselves by spindles (4), The blade cuts the annular weakening line to form the tamperproof ring of the cap. The carousel has an emitter (7) and a laser receiver (S) that cooperate to detect the presence or absence of the cutting edge of the fixed blade, The apparatus ensures good cutting quality.
