Abstract
A die-punch cutting apparatus for a continuous web thermal printer consists of a die body having a longitudinal I-shaped cutting opening and a punch body having a longitudinal I-shaped cutting blade which is slidably received in interfitting engagement within the I-shaped cutting opening of the die body. The I-shaped cutting opening and cutting blade include first and second spaced longitudinal cutting edges symmetrically disposed on opposing sides of a longitudinal centerline, and further include terminal end portions which are outwardly rounded in configuration. In operation, the first and second cutting edges of the punch body are slidably engaged with the first and second cutting edges of the die body for severing a printed section of print media from a continuous web, wherein the first cutting edges of the die body and the punch body cooperate to cut rounded corners at the trailing edge of a previously printed section of media, and the second cutting edges of the die body and the punch body cooperate to cut rounded corners at the leading edge of a section of print media to be subsequently printed.
