Multi-Wheel Screw Capping
Spindle Capping Machines
ZONESUN spindle cappers use multiple rotating wheels to tighten screw caps consistently. Choose tabletop, conveyor-based and high-speed models for different bottles, caps and production requirements.
Automatic Spindle Capping for Continuous Production
Spindle cappers are designed for packaging lines that require continuous bottle movement and reliable screw-cap tightening. Unlike single-head machines that stop each container beneath a capping head, spindle systems guide bottles between several rotating wheels that progressively apply tightening force.
How to Choose a Spindle Capping Machine
Start with the dimensions and construction of the bottle and cap. Important information includes cap diameter and height, bottle width, container material, required production speed and the torque needed to produce a secure closure.
For stable production, also consider how caps will be placed before tightening. An automatic cap elevator, sorter or vibratory bowl can reduce manual handling and support continuous operation. Servo-controlled models provide additional adjustment where products require more precise capping control.
| Configuration | Best For | Main Advantage |
|---|---|---|
| Standard Inline Spindle Capper | General screw caps and medium-speed lines | Flexible adjustment and continuous operation |
| Servo Spindle Capper | Products requiring greater capping control | More precise and repeatable adjustment |
| Capper with Automatic Feeder | Fully automatic packaging lines | Automatic cap sorting, delivery and tightening |
Frequently Asked Questions
What caps can a spindle capping machine handle?
Spindle cappers are mainly intended for continuous tightening of screw-threaded closures. Compatibility depends on cap diameter, height, shape and rigidity. Pump and trigger closures may require a dedicated cap-placement mechanism.
Can one machine handle different bottle sizes?
Yes. Conveyor guides, spindle-wheel spacing, belt height and tightening pressure can be adjusted within the supported size range. Change parts or a customized feeding system may be required for unusual containers.
Can the capper be connected to a filling line?
Yes. The machine can be integrated after a bottle filling system and before labeling or inspection equipment. ZONESUN can configure conveyor height, speed and cap-feeding equipment for the complete line.
