Butter wrapper packaging machine

摘要

The butter packaging machine comprises a folding compartment with a lateral guide (11) on each of its sides. It also has a centralising guide (10) positioned at one of its ends. These guides restrict the travel of a paper sheet (2) toward the underside of a piston (4) connected to a pre-folding part (8). The pre-folding part is provided with several radially projecting tabs (9) which ensure folding the sheet between the groove internal walls of the folding compartment. The assembly introduces the sheet into the compartment and forms folds on its lateral walls. The pre-folded sheet is directed towards a cavity whose internal volume is filled with a pat of butter placed by a filling part. The cavity is positioned on a rotating tray.
