CN861M
Servo Narrow Edge Automatic Edge Bander
Forty millimetres is where a bander is judged: the bed and the beam hold a strip that narrow across its full width, so the band sits flat instead of riding up at the trimming head.
Overview
- Fourteen cells in the order printed on the sheet: wide screen, separating agent, pre-milling, heat lamp, EVA gluing furnace, fast-melt tank, pressing, head-and-tail trimming, rough and servo fine trimming, four-head tracking, servo scraping, flexible flat scraping, cleaning and polishing.
- Panels from 40 mm wide and 9 to 60 mm thick, with band 0.4 to 3 mm thick and 12 to 65 mm wide.
- 16 to 23 m/min on an 8,990 mm frame, 800 mm wide and 1,900 mm high, with 25 kW installed.
- The EVA furnace sits on the machine and melts granulate in place, so there is no external tank to fill and no solvent to buy for cleaning.
- A fast-melt tank follows the furnace, so the melt reaches working temperature while the pot holds it.
- Servo fine trimming and servo scraping are positioned from the screen, which is what keeps a 40 mm strip even along its length.
- Four-head tracking, then cleaning and one polishing head finish the edge.

Station sequence
Station 01 is the wide screen and station 05 the EVA gluing furnace; the fourteen cells run from separating agent to polishing in the order printed on the sheet.
01
High-definition wide screen
A wide touch screen with fingertip control; a mouse and keyboard can be added if the operator prefers them.
02
Separating agent
A fine spray separates surplus glue from the panel face, so hot-melt does not mark the board after pressing.
03
Pre-milling
Two milling cutters re-finish the saw marks, burrs and out-of-square edges left by the panel saw, so the band seats on a clean face.
04
Heat lamp
The board and the glue are pre-heated before pressing, which keeps the bond even in cold weather.
05
EVA gluing furnace
The furnace melts EVA granulate and applies it to the panel face and the band in one pass; the pot sits on the machine, with no external tank and no cleaning solvent.
06
Fast-melt glue
The fast-melt unit brings the adhesive to working temperature in less time, so a cold start does not hold up the line.
07
Pressing
High-precision pressure wheels load the band evenly as it meets the panel, so the joint sits flat and holds.
08
Head-and-tail trimming
The band is cut flush at the leading and trailing ends — quickly, and without ragged corners.
09
Rough and servo fine trimming
Rough trimming takes the overhang and a servo-driven fine head finishes to the panel face at a set position.
10
Four-head corner tracking
Four driven heads round the corners at the leading and trailing ends, so the band follows the panel radius instead of cutting it square.
11
Servo scraping
A servo motor on a precision guide rail tracks the panel face; scraping depth and pressure are closed-loop, so the edge is neither over- nor under-scraped.
12
Flexible flat scraping
A sprung scraper follows the panel face instead of a fixed depth, so surplus hot-melt comes off without cutting into the board.
13
Cleaning
Residual hot-melt is diluted and isolated before polishing, so it lifts off instead of being smeared along the edge.
14
Polishing
Cotton polishing wheels clean the finished edge, leaving it smooth and even with the panel face.

What the machine is built to do
- Built around a 40 mm stripThe narrowest panel in the sheet is 40 mm: at that width the band is most of the edge, so the pressure has to be even across the whole face.
- EVA furnace on the frameGranulate is melted inside the machine, which removes the external melter, the transfer line and the solvent from the process.
- Fast-melt tankA second tank brings the adhesive up to working temperature quickly, so a cold start costs minutes.
- Servo fine trimmingThe fine head is positioned by servo, so the cut repeats after a band change instead of being dialled back in by hand.
- Four-head trackingFour motors carry the tracking unit, so the band turns both corners in one pass.
- 8.9 m frame800 mm wide and 1,900 mm high, with all fourteen cells present: nothing is dropped to save length.
