Standard Screw Cap And Bottle Examples

These examples show stable bottle formats and conventional round screw caps suited to continuous inline tightening.

Round, cylindrical, rectangular, flat and chemical bottles with separate standard screw caps for automatic linear capping — Actual cap and bottle samples determine rail height, capping-wheel pressure, bottle-side belt settings and sustainable line speed.

Method Comparison

Comparison With Other Capping Methods

Capping Method	Best For	Selection Note
Swing Arm Capping	Round screw caps, medium-speed lines	Flexible solution for standard caps
Linear Capping	Continuous screw cap tightening	Good for stable inline production
Tracking Capping	Higher speed lines	Reduces bottle stop time
Pump Head Feeding & Placing	Lotion pump and shampoo pump caps	Sorts and places pump heads before a separate tightening station
Trigger Sprayer Capping	Sprayer caps for cleaning bottles	Designed for long trigger heads
Four-wheel Capping	Screw caps and some pump caps	Stable side tightening and fast changeover
Press Capping	Press-fit caps	Suitable for pressing instead of thread tightening

Engineering Definitions

How To Read The Published Automatic Linear Capping Machine For Continuous Screw Cap Tightening Parameters

The website helps shortlist a machine. Final values are released only after the product, container, closure or label, required output and factory conditions are reviewed.

Bottle and cap range

Published dimensions are selection references. Neck finish, cap geometry, bottle support and physical samples control final approval.

Heads or stations

The listed quantity describes the configured capping positions; the cap-feeding method remains part of the system design.

Speed basis

A sustained bottles-per-minute target requires the real cap, bottle, feeder and upstream spacing conditions.

Closure result

Placement, tightening, pressing or torque checks use an agreed method and supplied package samples during FAT.

Final handover package

After configuration confirmation, the handover package supports installation, operation, maintenance and acceptance without publishing unconfirmed project values.

FAQ

Common Questions Before Buying

What is linear capping best for?

It is best for standard screw caps in continuous inline production.

Can it handle flat bottles?

Yes, if bottle holding and side guides are configured correctly.

Is it suitable for pump caps?

Usually pump caps need a dedicated pump head feeding and placing machine.

Can it connect with filling and labeling?

Yes. It is commonly used in automatic filling capping labeling lines.

What information is needed for the initial review?

Send bottle and closure photos, dimensions, target speed and line details for the initial review. Physical items are requested later only when tooling or FAT requires them.
