Abstract
Disclosed is a device by which a defective product is removed from a path through which products are continually fed. The device has a feeder feeding products, a sensor detecting defective products, and a remover taking the defective products from the path. The sensor outputs a signal denoting a defect in either the trailing half of a first product or the leading half of an adjacent second product. The remover has a function for obtaining the number which is a quotient obtained by dividing the distance between the sensor and the remover by the length of a normal product. The remover takes out the defective and the adjacent product when the number of products passing the remover is equal to the quotient obtained by the above calculation.
