    • Foam-adhesive application method in a paper bag production line, where said bag comprises two or more layers, where the paper material from which the bag is manufactured is continuously transported through the production line in a transport direction, where the bag production line comprises four stages:
      - A first stage where a first foam-adhesive line is applied to the bag material in the transport direction, the amount of adhesive being 80% or less of a corresponding starch-based adhesive;
      - A second stage where the two or more layers are superposed each other, and foam-adhesive is applied at least in a number of points distributed between the two or more layers;
      - Forming the two or more layers into a tubular form along the transport direction
      - A third stage wherein foam adhesive, the amount of adhesive being 80% or less of a corresponding starch-based adhesive, is applied to the free end of the tubular form before the free end is subjected to a folding mechanism, creating a folded bottom in the end of the tubular form;
      - A fourth stage where the tubular form is cut at a predetermined distance from the folded bottom thereby separating an open-ended bag from the tubular form;
      - Repeating the third and fourth stage
    • 在纸袋生产线中的泡沫粘合剂施用方法,其中所述袋包括两层或更多层,其中制造袋的纸材料沿运输方向连续运输通过生产线,其中袋生产线包括四个 阶段: - 第一阶段,其中沿输送方向将第一泡沫粘合剂线施加到袋材料上,粘合剂的量为相应的淀粉基粘合剂的80%或更少; - 第二阶段,其中两层或更多层彼此叠置,并且至少在分布在两层或更多层之间的多个点中施加泡沫粘合剂; - 沿传送方向将所述两层或更多层成形为管状形式 - 第三阶段,其中将泡沫粘合剂(相对于淀粉基粘合剂的80%或更少的粘合剂的量)施加到管状形式的自由端 在自由端经受折叠机构之前,在管状端部形成折叠底部; - 第四阶段,其中从折叠的底部以预定的距离切割管形,从而将开口袋与管形分开; - 重复第三和第四阶段
