Abstract
Diagnostic strips of the kind which are exposed to biological fluids such as blood or urine to detect or monitor medical conditions are cut sequentially from elongated cards by a reciprocating shear blade. The cards may be ones which exhibit defective areas that should not be included in the finished strips. Blade motion seats each newly cut strip on a movable strip carrier which abuts the blade during the cutting operation. The carrier then travels a nondefective strip to a pickup location where it is precisely positioned and picked off of the carrier for emplacement in a housing. A strip with a defective area is carried further to a discharge location where it is released into a waste receptacle. This enables more economical manufacture of diagnostic strips by efficiently making use of nondefective areas of cards that have defective areas.
