Pressureless Bottle Conveyor Systems
Connect beverage-line machines with segmented speed control and low-friction accumulation. The system manages bottle flow and limits the build-up of pressure between bottles, helping protect bottles and labels during transfer and buffering.
Line integration
Position in the Production Line
The highlighted rail shows how this conveyor system connects process machines. It is a transfer system across several sections of the line.

Filled-bottle transfer & buffering from filler outfeed to packaging infeed. Final covered sections are defined for each project. This example does not mean every connection requires the same conveyor configuration. Process machines are shown for context.
System Overview
The conveyor system links individual machines into a coordinated production line. Its task is to deliver bottles at the required rate while managing the temporary differences between upstream and downstream equipment.
This pressureless bottle conveyor concept combines sectional speed control with low-friction accumulation. Coordinating the conveying sections helps limit bottle-to-bottle backpressure and reduce rubbing, collision and tipping risks. Handling performance depends on the bottle format, filled weight, surface condition, settings and route.
Design the Connections Alongside the Machines
Conveyor planning starts with the actual machine positions and bottle flow. Define where bottles enter and leave each machine, where short-term accumulation is needed, and which access routes must remain clear. Confirm the conveyor route, transfer heights and operating sequence together.
For full-line planning, explore our bottled water production lines, juice production lines and carbonated beverage lines. The pre-sale engineering review can match conveyor sections to the selected filling, labeling and packaging equipment.
How Pressureless Bottle Conveying Works
Conveying and buffering are coordinated with the connected machines.
Handling Benefits
Design objectives for stable bottle flow and practical line operation.
Controlled accumulation

Line Integration
Pressureless bottle conveying connects process machines at multiple positions. The example above shows filled PET bottles from filler outfeed to packing-machine infeed. The red rail identifies the conveying system; the process machines provide context.
Empty-bottle air conveying and conveying of finished packs or pallets are separate handling tasks. Include them explicitly if they are required in the complete project.
- Filling-machine outfeed: Match bottle discharge stability, conveyor elevation and upstream run/stop behaviour. See the PET bottle water filling machine.
- Drying and coding: Confirm transfer geometry, surface condition and the infeed requirements of the coding and marking equipment.
- Labeling: Agree infeed pitch, flow stability and label/contact-surface compatibility with the labeling machine.
- Packing-machine infeed: Confirm bottle arrangement and the packer’s acceptance rate. Coordinate the buffer with the selected secondary packaging equipment.
- Line control: Document the required status signals, section-speed coordination, restart sequence and agreed response to a full buffer. Confirm the included conveying sections in the project scope.
Bottle & Label Compatibility
Provide representative bottles and drawings before confirming the conveyor design. PET and glass bottle applications are reviewed against the selected format and handling conditions.
- Geometry and stability: confirm the base, diameter or cross-section, height and centre-of-gravity behaviour with the intended fill level.
- Weight and rigidity: review filled mass and bottle stiffness when defining guides, transfers, speeds and accumulation conditions.
- Label and surface: include label material, decoration, contact-sensitive areas and any wet or warm surface conditions.
- Format changes: agree guide settings, change parts or stored settings where specified. Confirm what adjustment is needed for each approved format.
The final bottle range and operating conditions form part of the technical agreement and acceptance test.

Frequently Asked Questions
Handling principle, sizing, compatibility and integration.
What does pressureless bottle conveying mean?
It describes a conveying and accumulation approach intended to limit the backpressure between bottles. Segmented speed control and low-friction handling help manage bottle flow as it moves between machines. The approved bottle, layout and settings determine the actual operating behaviour.
Does pressureless mean unpowered or friction-free?
The conveying sections are driven and speed-managed. Mechanical contact still moves the bottles. Pressureless refers to limiting accumulation pressure; it does not mean zero friction or an unpowered gravity conveyor.
Does it guarantee zero scratches, tipping or line stops?
The design aims to reduce these risks. Bottle geometry, rigidity, labels, contact surfaces, transfers, settings and maintenance all affect results. Confirm the required handling performance using representative bottles and agreed test conditions.
How much buffer capacity do I need?
Start with the normal/peak line rate and the short interruption you want to accommodate. Then review the actual bottle size, layout and operating pattern. Usable accumulation capacity is confirmed for the selected arrangement; a stopped downstream machine cannot be buffered indefinitely.
Which bottle sizes and production speeds are available?
The bottle range and throughput are specified for the project. Send bottle drawings/samples, filled weight, label details and normal/peak containers per hour. No single fixed format range or output applies to every conveyor layout.
Is this the same as an empty-bottle air conveyor?
No. This page covers mechanically driven bottle conveying and accumulation between line machines. Empty-PET-bottle air conveying is a different system, typically using directed air and neck-ring support. Define that scope separately if needed.
Can it connect to existing machines?
Existing-line integration can be reviewed using the actual machine discharge/infeed details, available space and control interfaces. Provide elevations, transfer geometry, operating speeds and layout drawings. Our pre-sale review can identify the required interfaces.
Can PET and glass bottles use the same settings?
Do not assume one setting suits every format. Confirm the material, filled weight, bottle shape, stability and label/contact conditions. Agree the approved range and the adjustments required during changeover.
What cleaning, material and control features are included?
These are defined in the final specification. Confirm the contact surfaces, chain/belt system, lubrication requirements if applicable, cleaning method, section controls, sensing and machine signals. Component brands and electrical ratings follow the agreed configuration.
What should I send for a quotation?
Provide the factory layout, machine positions and connection heights, bottle drawings/samples, fill weights, label types, target output, intended buffering requirement and available utilities. Identify the machines and conveyor sections to include. Request a conveyor layout review.
