<p>The folding groove applying machine has a pair of endless members (10,12), between which a channel (S) through which corrugated boards (42) pass is put. The folding groove applying members (26,28) are correspondingly secured on each of the endless members (10,12). By causing the corrugated board to pass between the two corresponding endless members (10, 12) putting the corrugated board passing channel (S) between them, both the surface and back of the corrugated board (42) are pinched by the folding groove applying members (26,28), thereby causing folding grooves (92,94) to be applied to appointed positions of the corrugated board (42). The pair of endless members are endless toothed belts (10,12) and these belts are applied to toothed pulleys (14,16), (18,20) each making a pair at the left and right sides. Alternately, the pair of endless members are in the form of endless chains (10,12) which are applied onto sprockets (14,16), (18,20) each making a pair at the left and right sides. The endless chains may also be vee belts. The folding groove applying members are composed of segments (26), the section of which constitutes a projection, and segments (28), the section of which constitutes a recess.</p> |
