Abstract
Abstract A cutter for removing samples from a moving web comprises a knife having a pair of cutting edges that are selectively urged into contact with the web being cut. In one embodiment, the blades are crossed relative to each other while in a second embodiment the tips of the two blades have a common apex. The blades may be positioned so that they slope with or against the web being cut. The sample has an area coincident with an area monitored by a gauge to enable the gauge calibration to be determined.
