An in-line bottle filling machine, also known as a linear filler, arranges its filling nozzles in a straight line rather than on a rotary platform. Containers are conveyed in a linear path and are filled sequentially as they pass under the stationary nozzles. This design is particularly advantageous for handling non-round or unconventional container shapes that may not index well on a rotary carousel, and for production lines with lower to medium speed requirements. In-line fillers often have a smaller footprint than rotary machines of equivalent valve count and can be easier to access for maintenance and changeover. They are highly versatile and can employ various filling principles such as gravity, piston, or pump-based systems. A typical application is in the food industry for filling pouches, rectangular juice boxes, or irregularly shaped glass bottles for premium products. The linear motion is inherently gentle, reducing the risk of damaging delicate containers. Ace-Filling manufactures in-line filling solutions that can be perfectly tailored to specific container geometries and production layouts, providing an efficient and flexible packaging option for producers who require precision without the need for ultra-high speeds.
