Line layout
Conveyor transfer points around a spindle capper
Control bottle pitch and stability before the capper receives the pack.
The capper is only one part of the transfer path
Most inline capping problems are influenced by what happens immediately before and after the tightening zone. Uneven infeed, poor bottle spacing, over-filled accumulation or a rough discharge transfer can make a suitable capper appear unstable.
Transfer-point planning table
| Position | Risk to check | Useful evidence |
|---|---|---|
| Filler discharge | Filled bottles arrive too close together or with product on the neck. | Pitch, fill condition and conveyor speed reference. |
| Cap placement zone | Cap reaches the neck before the bottle is fully under control. | Slow-speed video of the first cap start. |
| Spindle zone | Side pressure or torque moves the bottle off line. | Belt setting, bottle weight and cap-height evidence. |
| Outfeed | Downstream backup pushes capped bottles into the machine. | Blocked-discharge and restart test. |
