ABSTRACT OF THE DISCLOSURE An apparatus for treating continuous unexpanded structural honeycomb material formed of permanently creasable material comprises rollers for drawing the material in the expansion direction whilst compressing it perpendicularly thereto so that it adopts a second unexpanded state. A guide receives the advancing material and permits slight re-expansion and a double acting severing device, e.g. a circular blade driven by a double- acting ram in forward and return strokes, severs the slightly re-expanded material to form cut lengths. The severing device may be located at the position of a guide of compact form, or at the outlet end of a guide in the form of a channel having at least one resilient wall. A receiving surface, formed in part by a conveyor belt may be proided to receive the cut lengths and allow them to expand. Guides for the expanded material may be arranged to discharge the expanded material from the receiving surface.
