A web of thin flexible material such as resin-impregnated cloth suitable for making expanded honeycomb core structures is drawn from a roll, the web being somewhat more than twice the width of the lay-up which is intended to be made. The double web passes through a printing station at which only one face has transverse lines of adhesive imprinted thereon. Each line extends only half-way across the web, and the lines on one half of the web are staggered along the length of the web with respect to the lines on the other half by a constant spacing. The web is slit into two halves, each being approximately one half of the width of the original double web. From the cutting station the two half webs pass over a pair of spaced turning bars which change the direction of movement of the respective half webs so that they are aligned edge to edge but with both printed faces in the same orientation so that the face of the bottom web engages the back of the top web.
