Abstract
Abstract An apparatus for cutting and sealing plastic material is disclosed including a gripper, a sealer and a cutter to make two parallel seals with a cut therebetween. The apparatus can automatically seal counted articles into individual packages and sever the packages into individual bags. The apparatus is suitable for use with automatic counting machines. The foregoing abstract is merely a resume of one general application, is not a complete discussion of all principles of operation or applications, and is not to be construed as a limitation on the scope of the claimed subject matter.
