Dual sealing system
Following a request from an ingredients supplier to a global soft drinks company for extra protection from cross product contamination during the case sealing process, Endoline Machinery developed a case sealing system which both glues and tapes filled cases – the new dual sealing system.
Utilising Festo pneumatics and Allen Bradley components, Endoline brought the technologies from its existing tape and glue sealing machines together to design the new system. The entire machine frame and side drives were altered to accommodate both the folding and gluing assemblies along with the taping system. The machine also has a special switch to disable the glue, and with the easily removable tape units it can be run to seal with both tape and glue or just one type of seal.
Once a filled box runs into the system, the dual action hook closes the rear flap before glue is applied and the outer flaps are closed. The glued case then moves under the taping head for final sealing.
With a daily output of over 10,000 cases, the machine is achieving a perfect seal on cases ranging from almost empty to 25kg in weight.
