Semi-automatic capper for twisting and screwing metal and plastic caps
In industrial packaging processes, secure and efficient capping is crucial for maintaining product integrity and preventing leaks. This involves adjusting the torque accurately to suit different cap types and sizes, ensuring a tight seal without damaging the caps.

Efficient capping for various cap types and sizes
The KAP 901 Semi-Automatic Capper by Kulp is a portable, hand-held capping system designed for efficient tightening of plastic and metal screw caps as well as metal twist-off caps. Operated via a pneumatic system, it utilizes an air motor to drive motion and includes a plastic mold to prevent cap damage due to friction. Torque adjustment is controlled through a compressed air inlet, and the system automatically stops once the desired torque is reached. Its design includes a balancer, making it weightless and easy to operate across different packaging lines. The capper can be easily installed on working tables or conveyor lines and is adaptable for both standard and special cap sizes. With a capacity to handle 800-900 packages per hour, it ensures a reliable and consistent capping process.
