Abstract
A dunnage system may include a converting station including a converter configured for pulling in a stream of sheet material and converting the material into dunnage, and an inlet guide having an inlet surface that is coiled such that first and second ends of the inlet surface are discontinuous with each other to define a gap therebetween, the inlet surface configured to channel the sheet material into the converter. A cutter for a dunnage system may include a blade with first and second phases of serrations that are coextensive over at least a portion of the blade, the first phase providing cutting serrations for cutting the dunnage, and the second phase comprising ledges for focusing the cutting and preventing or reducing bunching of the dunnage towards a side of the blade. A method of converting dunnage may also be provided.
