In-line cappers versus rotary chuck-style cappers

In-line cappers are traditionally cheaper than rotary chuck cappers, which can cost up to 10 times the price.

In-line cappers will typically have a smaller footprint than a rotary machine. In many cases, an in-line machine can be mounted over an existing section of bottle conveyor. Finally, in-line cappers typically have lower costs for the additional change parts required to run different sizes of containers and closures.

Rotary chuck cappers have much higher speed capabilities than in-line machines. Chuck cappers can be supplied with as many as 40 heads that operate at production speeds from as low as 10 bottles/min to speeds as high as 1,200 bottles/min. (In-line cappers are typically speed-limited to a maximum of 200 bottles/min. In-line cappers are limited in the diameter of cap that can be dependably applied—typically 28 mm to 70 mm. An In-line capper will generally be limited to applying closures that are round in shape. Chuck-style cappers can apply round, rectangular, square, oval, tapered, and reverse-tapered caps.
