Inline Screw Capping Machines

Inline screw cap tighteners are by far the most popular machines for capping most products that take a screw cap. Changeovers are easy with a wide range of bottle and cap sizes. There are also several variations of cap sorters available for flat caps, barrel caps and specialty caps using floor level elevator/sorters, centrifugal feeders, and vibratory feeders. Caps are tightened with 3 or 4 pairs of side tightening disks (depending on the model) that spin the cap on as the bottle is driven through the disks with side drive hugger belts that keep the bottle stable through the tightening process. The big advantage of an inline capper is its ease of changeover and simplicity of design. The disadvantage of an inline screw capper is, despite improving clutch control options, that torques applied to the cap can be relatively uneven compared to a good chuck capper, and particularly so when higher torque requirements must be met.
