The Cap Tightener is fully automatic and operates on pneumatic and optical sensor controls. After caps have been applied, the bottles move into position near the optical sensor of the Cap Tightener.

The optical sensor controls the entry of bottles into the Tightener and allows the system to function without operator assistance.

Once moved into position, the bottles are held in place, one at a time, by an off-setting pair of high impact aluminum gripper pads and flange support rings. The gripper pads hold the bottom of the bottle to prevent the bottle from spinning during the cap tightening process.

The flange support rings receives the downward capping pressure so as not to force excessive pressure onto the conveyor. Other cap tightening devises will typically allow this pressure to be applied to the moving conveyor thus shortening the life of the conveyor motor.

As the rotating cap tightening devise pushes downward and onto the cap, the cone shaped rubber insert grabs the cap by the shoulder and spins it into a tightly fixed position to complete the capping process.

An especially unique feature of the Cap Tightener is the adjustable clutch control mechanism which allows the operator to choose the selected torque or tightness of the cap on the bottle.

This helps to prevent over tightening and marring of the cap shoulders. Once caps are securely tightened, the filled and capped bottles are then moved down the conveyor for collection onto either a rotating or an in-line collection table.

The controls are specially designed to help prevent caps from being cross threaded on the bottles. The system employs a multi-step tightening process as described above while maintaining tightening speeds of up to 50 bottles per minute.

The entire operation automatic, complete and relatively simple to operate and maintain. The changeover from one size bottle and/or cap requires a minimum of tools.

The stainless steel construction ensures a long and durable life. Because there are few moving parts, little maintenance is required to keep the system operating at maximum efficiency.
