Precision cutting instrument for preparing immunoassay strips

An apparatus for cutting a solid sheet into multiple strips which comprises:

• a base plate having an upper surface within which longitudinal grooves are formed and on which the solid sheet is received;
• a top plate having longitudinal slots extending therethrough;
• means for positioning said top plate in operative relation to said base plate covering the solid sheet received thereon with said longitudinal slots of said top plate overlying and in registry with said longitudinal grooves of said base plate;
• a plurality of cutting elements;
• means for holding said cutting elements;
• transport means for imparting relative longitudinal movement between said holding means and said base plate with the cutting elements projecting through said longitudinal slots of said top plate and through said solid sheet into the longitudinal grooves of said base plate whereby said sheet is cut into a predetermined number of equivalent longitudinal strips, aligning means on the base plate and stamp means engageable with the aligning means on the base plate in operative relation to the grooves for marking the solid sheet before cutting.

An apparatus for cutting a solid sheet into multiple strips which comprises:

• a base plate on which the solid sheet can be placed and having a track way means thereon;
• a top plate having slots extending therethrough and adapted to be positioned on top of said base plate;
• a plurality of cutting elements secured within a holding means;
• and transport means for moving said holding means across the top plate and said cutting elements through said slots whereby said sheet can be cut into a predetermined number of strips, said transport means including wheel means rolling upon said track means, the side edges of the top plate cooperating with the track way means on the base plate to keep the transport means properly aligned during movement.
