The positioning of the hole (as opposed to the package itself) is captured by a camera in the machine, which ensures a highly precise cap application. Cap holders are designed to move independently from one another for even greater accuracy. This feature is standard for TPA and TGA lines and unavailable for ReCap and SlimCap lines.
Double Hotmelt Applicator
The higher the speed of the machine, the more accurately it needs to function. In this case, the application of hot melt is synchronised by a servo drive. Thanks to its precise, smooth movements, the number of defects and spills is minimised. (For screw cap application)
Several factors contribute to the easy operation of this cap applicator: the Tetra Pak Operator Panel with its intuitive touch screen interface; ground level access to essential working parts; large windows through which operators can observe operations at first hand.
The auto-eject function measures and calculates whether or not the screw cap is positioned correctly on the package. If it detects an incorrectly positioned cap, the package is automatically ejected from the line.
Packages pass through the machine in a straight line without stopping or changing direction. This results in a swift but gentle handling and good package shape. Caps are applied in line as they pass through the machine which ensures accurate positioning.
