Abstract
An apparatus and method for detecting defects in the cover sheets used to manufacture diapers is disclosed. A linear sensor is used to detect defects in the cover sheet web before it is combined with the absorbent material to form a diaper. When a defect is detected, the manufactured diaper containing the defective cover sheet is ejected from the line after a delay which is dependent on the speed of the process.
Claims8
A method for detecting defects in a web used in the manufacture of diapers, comprising the steps of:
- feeding the web to a diaper making machine which combines the web with an absorbent material to produce a diaper,
- using a linear sensor to detect defects in the web before it is combined with the absorbent material, and
- using a signal generated by the sensor indicative of a defect in the web to eject the diaper produced by the diaper making machine which contains the defect in the web.
Apparatus for detecting defects in a web material used in the manufacture of diapers, comprising:
- means for feeding the web to a diaper making machine which combines the web with an absorbent material to produce a diaper,
- a linear sensor for detecting defects in the web before it is combined with the absorbent material, and
- means responsive to a signal generated by the sensor indicative of a defect in the web for ejecting the diaper produced by the diaper making machine which contains the defect in the web.
