Abstract (en)
[origin: CN105946283A] The invention relates to a changeable groove line extrusion stand for a folding box pasting apparatus. The groove line extrusion stand is especially suitable for extruding semi-finished products formed from corrugated cardboards. The invention also provides a method for producing folding boxes with corrugated cardboards by using the groove line extrusion stand according to the invention. The groove line extrusion stand comprises a vertically-movable side face extrusion roller used for extruding semi-finished products folded from groove line areas on the outer sides. Aside from the side face extrusion roller, the extrusion stand also comprises a usable middle extrusion roller pair which comprises middle extrusion rollers on the upper portion and the lower portion and thus can extrude middle areas of folded semi-finished products. With the additional middle extrusion roller pair, folded corrugated cardboard semi-finished products can be extruded in the width direction and after extrusion, the widths of extruded semi-finished products have no thickness differences or only have minor acceptable thickness differences.
