Abstract
In a cutting apparatus a rotating carousel conveys caps made of synthetic plastic material to a fixed blade having the shape of a circumferential arc. The caps are rotated about themselves by spindles. The blade cuts an annular weakening line to form the tamperproof ring of the cap. The carousel has an emitter and a laser receiver that cooperate to detect the presence or absence of the cutting edge of the fixed blade. The apparatus ensures good cutting quality.
Claims14
1-13. (canceled)
A cutting apparatus, comprising
- (a) a cutting device configured for forming at least one weakening zone on at least one cap, said cutting device including a fixed blade having a cutting edge configured as a circumferential arc;
- (b) a conveying device arranged adjacent to said cutting device for supplying said cutting device with said at least one cap, said conveying device including at least one movable supporting element which carries said at least one cap;
- and
- (c) at least one sensor to detect at least one faulty operating condition of said cutting device, at least a portion of said sensor being mounted on said movable supporting element, said at least one sensor including a presence sensor that detects at least one of the presence, the absence, and the deviation from a desired position of at least a portion of said cutting edge, said sensor portion being arranged adjacent to and out of contact with said cutting device when said sensor portion is in an operating condition, said at least one sensor and said cutting device being separate components, said sensor portion being movable along a closed-loop path and being periodically operable with respect to said cutting edge.

A method for cutting a cap, comprising the steps of
- (a) supplying a cap to a cutting device that includes a fixed blade having a cutting edge configured as a circumferential arc;
- (b) forming at least a weakening zone on the cap with said cutting device;
- (c) detecting with a sensor whether said cutting device has a faulty operating condition, said detecting step including detecting at least one of the presence, absence, and deviation from a desired position of at least a portion of said cutting edge;
- and
- (d) providing a movable supporting element that carries the cap and at least a portion of said sensor to said cutting device, said sensor portion being arranged adjacent to and out of contact with said cutting device when said sensor portion is in an operating condition, said at least one sensor and said cutting device being separate components, said sensor portion being movable along a closed-loop path and being periodically operational with respect to said cutting edge.
