Senmei SM600-W Paper Tube Outer Coiling Machine

Overview

Outer coiling and expansion, CNC-stepped.

The Senmei SM600-W is the outer coiling and expansion station on Senmei's modular paper tube platform. A CNC stepping system drives the curling head along the tube length, holding the edge profile uniform across the full cycle. The platform is built around wall thicknesses from 0.8 mm to 1 mm — exact tube diameter and throughput range are confirmed per inquiry by Senmei engineers based on the specific stock and edge profile.

The same frame supports inner curling with a tooling swap — Senmei ships both the outer-coil and inner-curl variants from this platform. Recipe parameters — feed rate, head pressure, dwell time — are stored per tube diameter and stock, and surface on the HMI for fast changeover.

Key features

Built around uptime, not just speed.

CNC stepping system. Servo-driven head motion with sub-millimeter positioning across the full tube length.
Uniform edge profile. Pressure and dwell time held constant regardless of tube length, so every can curls to the same diameter.
Dual-purpose frame. Switch between outer coiling and inner curling with a tooling swap — same machine, two processes.
Recipe-driven changeover. Tube diameter, feed rate, head pressure, and dwell time are stored per stock.
Quick-change tooling. Tooling swap in under 10 minutes; recipe auto-loads from the HMI.
Touchscreen HMI. 10-inch industrial panel with multi-language UI and on-screen troubleshooting.
Safety-integrated guarding. Category 3 PL d safety circuit, CE-marked.

Working principle

How the SM600-W runs.

A tube is loaded into the curling station by hand or by an upstream conveyor. The CNC stepping system indexes the curling head along the tube length at a recipe-controlled feed rate. As the head advances, it forms the outer edge of the tube to the target diameter — uniform pressure, uniform dwell time, uniform edge profile.

On the inner curling variant, the same frame indexes a different head inside the tube to form the inner edge. Recipe parameters — feed rate, head pressure, dwell time — are stored per tube diameter and stock; the HMI surfaces live profile data and flags drift before it shows up on a sealed can.

Applications

Where the SM600-W fits.

Potato chip cans. Paper cans with outer curl for sealing on the Senmei SM600-F.
Snack cans. Cans for nuts, popcorn, and extruded snacks that need a tight, uniform edge.
Fireworks tubes. Kraft tubes with outer curl for downstream closure.
Cosmetics tubes. Premium tubes with a clean outer profile for foil labeling.
Industrial cores. Cores with outer expansion for film and paper winding.

Why Senmei

Three reasons customers keep coming back.

01

Tuned to your stock, not ours.

Every SM600-W ships with a recipe card for your specific tube diameter and stock. Feed rate, head pressure, and dwell time are dialed in before crating.

02

Tested on your tubes, in our factory.

Senmei engineers run a factory acceptance test with your stock and verify edge profile repeatability before the machine ships.

03

Support that doesn't expire.

Lifetime remote diagnostics, on-site engineer dispatch available globally, and a 12-month warranty — extended to 24 months on request.
