Method and an apparatus for manufacturing side wall of a cup for cupped cake

A high speed production apparatus for making a side wall of a cupped cake cup, comprising:

• a blank stocker positioned and configured to receive a plurality of fan shaped blanks in a stacked state;
• a forming cone roll having a frusto-conical configuration rotatable around a rotating axis and having a plurality of sucking and exhausting holes arrayed in a line along the rotating axis;
• a holding cone roll positioned parallel to said forming cone roll, configured to approach toward the forming cone roll to form a desired distance from the forming cone roll and configured to rotate in an opposite direction to the forming cone roll,
• wherein said sucking and exhausting holes urge said blank wound around a peripheral face of the forming cone roll by suction, and the forming cone roll and the holding cone roll shape the blank into the side wall of the cupped cake cup having a small diameter side end and a large diameter side end of a specified dimension in one rotation of the forming cone roll.

An apparatus for high speed production of a side wall for a cupped cake cup, comprising:

• a paper cutter disposed and configured to cut a blank from a paper sheet;
• a transport device configured to receive the blank from the cutter, apply a sealing agent to the blank and transport the blank;
• a forming cone roll having a frusto-conical configuration, configured to rotate around a rotating axis and having a plurality of sucking and exhausting holes arrayed in a line along the rotating axis, said sucking and exhausting holes being configured to hold the blank against the forming cone roll by suction and releasing the blank by exhaustion;
• a holding cone roll positioned and configured to approach toward the forming cone roll to form a gap for receiving the blank and hold the blank against the forming cone roll while the forming cone roll makes one rotation,
• wherein the blank is formed into the side wall of the cupped cake cup while the forming cone roll makes the one rotation.
