  • Patent number: 5349890
    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 This arrangement reduces the amount of heat withdrawn from the knife.

  • Patent number: 5261515
    Abstract: A mechanical disconnect for the pedal operating rod of an attaching machine comprises a stationary trip slide having a downwardly inclined cam surface and a housing enclosing the trip slide and reciprocable thereon. The housing is connected to the clutch operating rod. The housing also includes a transverse trip spacer pin and a latch having a follower nose engaging the cam and a central L-shaped opening receiving the pin in the horizontal leg of the opening. A spring urges the latch toward the slide. When the pedal is depressed, the latch pulls down the housing so that the clutch activating pull down rod moves away from the clutch dog. Further downward movement of the pedal cams the latch away from the slide so that the spacer pin aligns with the vertical leg of the "L" permitting the housing to pop up and the pull down rod to engage a clutch dog.
