Abstract

PURPOSE:To prevent getting out of a cell shape, generating an unstretched part, and stretch it equally, by cutting an unstretched block of a honeycomb shape material, inserting it between the belts, carrying it by snake motion between the belts, and after that, stretching it. CONSTITUTION:An unstretched block 7 of a honeycomb shape material is cut off, it is fed along the guide 14, and is inserted between the belts 11, 13. The unstretched block 7 which has been inserted between the belts 11, 13 is carried by means of friction force of the belt 11. In this case, since spring force is put to the tension roll in the direction shown by an arrow P, the unstretched block 7 is bent in the foil-laminated direction along a curvature of the roll, and is carried by snake motion. According to such a constitution, since each foil slips off each other, it is possible to get rid of entanglement between foils, which is caused by a cut burr on the cut surface.
