ABSTRACT:
A device for aiding in the preparation of very thin slices of foam sheet material that is to be examined under a microscope. The device has a clamp arrangement for holding a sample of foam sheet material. A screw feed arrangement permits the foam sheet material to be advanced past a planar surface where a very thin slice of foam material can be removed. A clamping arrangement keeps the foam sheet material in linear alignment at the location where the sample is severed. A detent arrangement permits a metered amount of foam sheet material to be advanced past the planar cutting surface by the screw feed arrangement.
The method of preparing a foam sample by first severing the foam material while it is held by the apparatus, thus establishing a planar cut, then positioning the material for a second cut which is then made parallel to the first cut.
