Abstract
Apparatus for forming foldable plastic products (e.g., chair mats) includes a forming station for forming thermoplastic material into a shaped body, and a slitting station for slitting the shaped body to form a slit having first and second slit segments which establish a flexible hinge to allow adjacent sections of said shaped body laterally of said slit to be folded into juxtaposed relationship with one another. The slitting station employs an especially configured blade that has portions respectively corresponding to the first and second slit segments so that the slit segments may be simultaneously formed in the shaped body.
