The GPM-320 is the next step up from the GPM-315 and is designed to handle SRA3 sheet sizes. This simple to use machine will crease and perforate to a very high standard. Due to the eccentric wheel operating mechanism even the heaviest card can be creased or perforated with the minimum effort. The thumbwheel angle adjustment allows skewed paper to be creased accurately.
The GPM-320 is a heavy duty, manual creasing and perforating machine, suitable for handling SRA3 size card and paper. The GPM-320 features double crease paper guides with "flip over" stops, paper skew adjustment, and three options for crease width.
