发明名称 Method of manufacture of a glued top and bottom bulk container
摘要 A process for the construction of a flexible bulk container including a glued bottom portion and/or a glued top portion. A sidewall blank having a hollow tubular configuration with an upper and lower portion suspended in the shape of the desired container and positioned over a bottom wall located on a raised work area. Adhesive or glue is applied to either the bottom wall and/or the sidewall in areas where the sidewall blank will be permanently in contact with the bottom wall. The sidewall blank is lowered into contact with the bottom wall such that the lower portion of the sidewall blank is located below the work area and the upper portion is located above the work area. The sidewall blank is secured to the bottom wall by folding the upper portion of the sidewall blank over the bottom wall thereby contacting the adhesive or glue and forming a glued bottom bag.
