Method of manufacture of a glued bottom bulk container

A method of manufacturing a flexible bulk container having a sidewall and bottom wall, said method comprising the steps of:

• (a) supplying a sidewall blank having a substantially hollow tubular configuration, said sidewall blank having an upper portion and a lower portion and an inside and an outside;
• (b) supplying a bottom wall of circular horizontal cross-sectional shape;
• (c) placing the bottom wall on a raised work area;
• (d) applying adhesive to the bottom wall;
• (e) positioning the sidewall blank over the raised work area and lowering the sidewall blank 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;
• (f) forming fins from the upper portion of the sidewall blank;
• (g) securing the sidewall blank to the bottom wall by folding the upper portion of the sidewall blank over the bottom wall, such that the inside of the blank contacts the adhesive located on the bottom wall;
• and
• (h) securing the fins to the outside of the folded over lower portion of the sidewall blank.

• (a) supplying a sidewall blank having a substantially hollow tubular configuration, said sidewall having an upper portion and a lower portion and an inside and an outside;
• (b) supplying a bottom wall of predetermined horizontal cross-sectional size and shape having an inside and an outside and an access spout located at the center point of said horizontal cross sectional shape;
• (c) placing the bottom wall on a raised work area having a central opening for accommodating said discharge spout;
• (d) applying a first component of an adhesive to the outside of the bottom wall and applying a second component of an adhesive to the inside of the upper portion of the sidewall blank;
• (e) positioning the sidewall blank over a raised work area such that the lower portion of the sidewall is located below the work area and the upper portion is located above the work area;
• and
• (f) subsequent to steps (a) through (e), securing the sidewall blank to the bottom wall by folding the upper portion of the sidewall blank over the bottom wall, such that said second component of adhesive on the inside of the sidewall blank contacts said first component of adhesive on the outside of the bottom wall.

• (d) applying adhesive to the bottom wall;
• (e) suspending the sidewall blank over the raised work area using a movable carriage;
• (f) positioning the suspended sidewall blank over a raised work area and lowering the sidewall blank 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;
• and
• (g) subsequent to steps (a) through (f) securing the sidewall blank to the bottom wall by folding the upper portion of the sidewall blank over the bottom wall, such that the inside of the blank contacts the adhesive located on the bottom wall.
