ABSTRACT:
Apparatus for cutting web material transversely to form sections has an arrangement for advancing the material a section at a time across a linear cutting edge. A linear guide parallel with the edge carries a circular blade which overlaps the linear cutting edge said blade being reciprocably driven along a linear guide. Each forward, and each reverse, cutting-stroke of the circular blade cuts off the then advanced section. The advancing arrangement is timed to operate between the ends of the forward strokes and the beginnings of the reverse strokes of the circular blade and vice versa. A preliminary advancing arrangement is provided for advancing a measured amount of web material to form slack which is taken-up by advancement of the material across the linear cutting edge. Structural honeycomb material may be produced by using two layers of material laminated together by bands of adhesive, and bearing other bands which are exposed, and arranging pressing devices which follow the circular blade and press the sections into a receiving throat. The pressing action displaces the cut sections to give a honeycomb material with the odd and even pairs of layers in different registries.
