Tray-Shrink Wrapping System
This multiple feed shrink wrap machine is fully automated using PLC controls. The tray mechanism prepares the unfolded tray whilst products are being collated.
A "U "shape is formed during the process of drawing the unfolded tray from the magazine. It is then held firmly to the carrier chain by mechanical fingers and indexed forward.
The collated items are now transferred to the tray and indexed forward. During this indexing, the corner flaps located at the vertical ends of the "U " are folded and hot- melt glue applied on their outside faces.
The amount of glue and its position are accurately controlled by a PLC. On the last index the unfolded ends are folded and pressed against the glued surfaces till it is ready to be fed into the Shrink Wrapper
