Roll Feeders in the Manufacturer's Catalogue
A roll feeder advances strip with driven rolls, timed to the press. The manufacturer's platform catalogue documents the roll feeding branch in a roll feeder machine listing, published in coil width steps from 200 to 1,300 mm. The figures below are that listing's published data; the feeding range as a whole is summarised on the coil feeding lines page.
| Item | Published catalogue data |
|---|---|
| Roll feeder listing — widths | Coil widths 200 / 300 / 400 / 500 / 600 / 800 / 1,000 / 1,200 / 1,300 mm |
| Roll feeder listing — thickness | Max 3.2 mm |
| Roll feeder listing — speed | Feeding speed 0-22 m/min |
| Roll feeder listing — accuracy | ±0.1 mm, with pneumatic release system and precision control, per the listing |
What the Listing Describes
The roll feeder listing describes a servo motor and servo drive of high torque and low inertia — the branch's modern form, where the rolls are servo-driven rather than geared from the press crankshaft — with a pneumatic release system, three operating modes (automatic for mass production, manual and setup for initial adjustment and coil-end feeding), a rigid high-concentricity body structure, and a desk-type control cabinet with slanted top and a 7-inch touch screen panel. The pitch is set at the panel and held by the drive; what changes between jobs is the stored setting, not the gearing.
Roll Feeder or Servo Feeder?
- Roll feeder: the catalogue's roll feeder listing is built around roll feeding of coil 200-1,300 mm wide at up to 22 m/min.
- Servo feeder: the NCF pattern adds stored groups of different feed lengths (20 groups in the listing, a listed option) for multi-product work on one line.
- Gripper feeder: for short pitches and delicate surfaces, where the stock is clamped rather than rolled.
Upstream, the roll feeder takes strip from the straightener and the decoiler; downstream it serves the die. The feeder, straightener and press are quoted as a matched configuration — width, thickness and pitch are the details to state with the enquiry.
Frequently Asked Questions
What coil widths do the roll feeders cover?
The roll feeder machine listing publishes width steps from 200 to 1,300 mm with a maximum material thickness of 3.2 mm.
What feed speed and accuracy are published?
The roll feeder listing publishes a feeding speed of 0-22 m/min and a feed accuracy of ±0.1 mm under its pneumatic release and precision control — the catalogue's figures for that listing.
Is the roll feeder driven by the press or by its own motor?
The documented listing is servo-driven: a high-torque, low-inertia servo motor and drive run the rolls, with automatic, manual and setup modes. The configuration for your press is confirmed in the quotation.
Can a roll feeder handle coil ends and setup pieces?
The listing's manual and setup modes are described for production initial adjustment and coil ends feeding, before automatic mode takes over for mass production.
