Abstract
A dunnage machine and system, and a method of producing dunnage. The dunnage machine can have rotatable forming members with recesses formed thereon. Stationary protruding members can extend into the recesses. A cutting system is provided for cutting dunnage produced by the dunnage machine or system, and a lock mechanism is also provided for locking the cutting system when a cover is removed from the dunnage machine.
Claims15
A dunnage machine comprising:
- an inlet;
- at least one forming member;
- a blade attached to a slidable blade mount, the blade being disposed near an exit region of the plurality of forming members;
- at least one elongated frame member connected to the slidable blade mount, the at least one elongated frame member being pivotably connected to a fixed point relative to the dunnage machine;
- a handle biasing member connected to a first end portion of the at least one elongated frame member;
- a handle surface disposed near a second end portion of the at least one elongated frame member, wherein when the handle surface is depressed, the blade descends, and wherein when the handle surface is not depressed, the handle biasing member biases the at least one elongated frame member upward causing the blade to ascend;
- at least one pivot arm;
- at least one catch member connected to the at least one pivot arm;
- and
- at least one biasing member connected to the at least one pivot arm, wherein when the at least one pivot arm is pivoted to a downward position, the at least one biasing member biases the at least one catch member toward a cross member that is attached to the at least one elongated frame member to couple the at least one catch member with the cross member and prevent the at least one elongated frame member from being moved, and wherein when the at least one pivot arm is pivoted to an upward position, the at least one biasing member biases the at least one catch member against a cover of the dunnage machine.
