Paperboard score bend testing device and method

摘要

A device and method for measuring the force or pressure required to break a score and bend a sheet of paperboard along a pre-formed score line. The device includes means for clamping one portion of the sheet between a pair of stationary plates, with another portion of the sheet extending beyond the plates, and a moveable plate co-planar with, but spaced a short distance from, one of the stationary plates and engageable with the other portion of the sheet. The device includes a mechanism for moving the moveable plate out of the plane of one of the stationary plates, to break the score and bend the sheet at the score line, and a gauge for measuring the force required to bend the paperboard sheet at the score line.
