ABSTRACT:
A paper cutting system includes a cutting assembly, a transport moving a web through the cutting assembly, a vacuum plenum utilizing a vacuum source to control the web moving through the cutting assembly, an air source providing purge air to the cutting assembly for removal of debris, and a heat exchanger normalizing a temperature of the purge air with respect to a temperature of ambient air prior to the purge air reaching the cutting assembly. The heat exchanger may be operated using the vacuum source.
