DESCRIPTION
The RELDA^® 2000 edge shaping machine is ergonomically designed and easy to adjust. It is preset for conventional shaping jobs : flat and rounded edge forming and chamfering and beveling.

It is design for manually shaping the edges of glass sheets from 2 to 19 mm thick. The adjustable belt speed optimizes the use of the different qualities of abrasives and polishing bands currently available on the market : diamond, carbide, aluminium oxide, cork, cerium oxide, etc.

Its modular design allows it to be customized for each user.

USE
1) Many possibilities of edge shaping and very easy to use :

The RELDA^® 2000 machine is designed for conventional shaping jobs :
. Polished flat edges,
. Chamfered edges,
. 45° chamfers and 30°, 20° and 10° bevels with an angular accuracy better than   <1°.

The machine is designed to be as easy as possible :
. 5 preset angular positions;
. Contact roller and guide roller assembly height adjustable;
. Band installation facilitated by a system for immobilizing the pulley under tension and when slack and excellent band accessibility.

The edge of the glass is shaped :
. By pressing it against the contact roller,
- For flat edges on thick glass sheet (>;6 mm)
. By the free section of band between the contact roller and guide roller,
- For flat edges on thin glass sheets(< 6 mm),
- For rounded edges, chamfers and bevels.

The following diagrams show the five angular positions and six working positions :
. Positions 1, 2 et 3 : Bevelled edges 10°, 20° et 30°;
. Position 4 : Grinded arris or chamfers ;
. Position 5 : Flat edges < 6 mm ;
. Position 6 : Flat edges > 6 mm.

To obtain these working positions, the machine includes two independent setting systems :

. Contact roller and guide roller assembly height adjustment, variable over a range of 120 mm;
. Angle of the free section of band, to be selected from five preset positions on the sector corresponding to the most widespread edge angles, i.e. 10°, 20°, 30°, 45° and 90° from horizontal.
Positions 1, 2, 3 and 4 are obtained by first setting the angle, then the height.
Positions 5 and 6, are set by first passing the band in front of the guide roler, then setting the angle to 90°, then setting the height such that the glass sheet is between the contact roller and guide roller .

2) Adjustable belt speed :

The RELDA^® 2000 is characterized mainly by a feed rate adjustable between 6 and 30 meters per second using a frequency variator.
Recommanded belt speed for the different types of bands :
. Silicon carbide abrasive bands : 20 m/sec ;
. Diamond abrasive bands : 30 m/sec;
. Cork polishing bands : 20 m/sec;
. Aluminium or cerium oxide polishing bands : 10 m/sec.

3) A Highly modular rail system and castor roller table : The machine is equipped with a system of extruded aluminium roller rails, very easy to adjust. The system is modular : and can be added to or customized by each user. - Basic version : a 1200 mm rail with 11 rollers.     Standard Configuration

- Many options are available : (see parts list for details)
. Additional bearing rails (with double crosspiece and indexable positionning lever). . Roller half-rails for guiding in depth.	. Castor roller table kit with jigs providing a large work surface 1200 mm x 800 mm for shaping the edges of large size sheets. The castor rollers facilitate effortless crosswise and lengthwise movements of the sheets. . Stainless steel collecting tray for the castor roller table. . Guide roller half-rails in depth. The two half-rails provide a depth stop for making long straight cuts, especially for bevelled edges.
. Linear guide trolley 500 mm x 250 mm for shaping small volumes facilitates straight cuts.	. Kit for making circular cuts, with two vertical axis guide rollers mounted on the first rail to provide circumferential guidance when shaping the edges of circular plates. The roller position is adjustable according to the plate diameter (min. dia.: 400 mm). . Castor roller table. . Stainless steel collecting tray for castor roller table.

4) A performing coolant system : The machine can be supplied with tap water or by closed circuit. The pump for closed circuit use is available as an option. The coolant spray is directed onto the glass/band contact area by articulated pipes and two swivel nozzles. (see photo opposite)

MAINTENANCE

Maintenance of the machine is easy and reduced :

. Excellent accessibility of the stainless steel setting tank ;
. The pulleys are easily accessible and removable ;
. The drive and driven pulleys are interchangeable ;
. The bearings are sealed and protected by packing rings.

SAFETY

The machine has an on/off switch and an emergency stop switch. It is turned back on by rotary switch.

In case of a power failure, the machine stops and does not restart automatically.

Furthermore, the machine power supply is disabled when the band access door is unlocked.

WARRANTY

The RELDA^® 2000 machine is covered by a six-month warranty for normal use.
