Bottle dimensions
Diameter, height and shoulder shape affect how bottles separate, stand up and transfer. Even bottles with the same nominal size can feed differently if the base or wall stiffness changes.
Sizing guide
Bottle unscrambler sizing guide
Correct sizing starts with the physical bottle format and finishes with the line speed and transfer layout.
Specification advice
What this means for the bottle infeed section.
Bottle weight and stability
Lightweight bottles are more prone to tipping, bouncing and bridging. The machine route must keep bottles controlled without crushing or deforming the container.
Line speed and buffer
The bottle unscrambler should feed slightly ahead of the downstream machine requirement, while still allowing accumulation and avoiding back-pressure problems.
Practical checks
Use the bottle and line data to reduce quote guesswork.
The best enquiry includes real bottle information, the target line speed and details of the downstream equipment. This gives the supplier enough information to recommend a sensible machine route instead of guessing from a catalogue picture.
For urgent projects, send bottle photos, sample dimensions, output target, conveyor height and a short description of the current line problem.

Questions
Common questions before choosing a bottle infeed route.
Why does bottle size matter?
Size affects separation, transfer and orientation. Small differences in base or shoulder geometry can change how the bottle behaves.
Can one machine handle many bottle sizes?
Often yes, but the range and changeover method must be checked with real bottles.
Is headline speed enough to choose a machine?
No. Real speed depends on bottle stability, downstream demand and how the line is integrated.
