Abstract
A heated knife has a motor adapted to drive the knife against a cutting block with the web inbetween. The knife body is metal and has a cutting edge with side surfaces at an obtuse angle to each other. The knife is formed with a lengthwise bore which houses a Calrod capable of heating the knife up to about 950.degree. F. The knife body has relatively thin lateral ears spaced from the heater and which receive support bolts from the opposite ends of a driving yoke by which the motor drives the knife. This arrangement reduces the amount of heat withdrawn from the knife.
