<p>A knife holder and knife therefor to be used on a machine for dicing or cutting plastics, the knife holder being an elongated body having a channel therein, the channel being shaped to hold an elongated insertable knife blade against the front wall of the channel, and an elongated wedge mounted between the knife and the back wall of the channel to clamp the knife securely in the knife holder. The walls of the channel are divergent from each other. The cooperation between the knife, wedge, and front and back walls of the channel is such that wedge-fastening screws or bolts have reduced forces acting on them. In a second embodiment, means are also provided whereby regound or replacement knives may be fitted into the knife holder with a minimum of adjustment necessary in respect to the fly knives of the machine.</p> |
