MACHINE FOR MANUFACTURE OF CARTON

PROBLEM TO BE SOLVED: To enable easy changing of the size of a corrugated carton in a short time by making it possible to cause the connection part of a carbon supply part to ascent/descent almost perpendicularly. SOLUTION: Plural corrugated cartons 1 are placed on the fixed rest 23 of a carton supply part 20 and are fixed using a fixed spacer 21 and a mobile press plate 22. After that, a connection part is caused to ascend or descend using the elevator device 24 of the carton supply part 20 so that a carton manufacturing operation can be performed in accordance with the side of the carton 1. Consequently, the bottom part of the carton 1 is adjusted so that the bottom part coincides with the reference operating height 31 of a carton making part 30. The carton 1 retained on the connection part at the tip of the carbon supply part 20 undergoes a widening step and a flange folding step which are performed along the line of the reference operating height 31 of the carton making part 30, and a flap fixing step which is performed on the support table 32 of the carton making part 30.
