Waste Rollers from Welger –Universal and economic in use.Welger products with their high levels of auto-mation offer the advantage of integration intoalmost all operational processes in trade andindustry. Our solutions, tailored to the market,allow for easy processing of a great varietyof materials already at the waste site.

Equipped with special features they can alsobe used in many areas with increased safetyand hazard requirements, e.g. in the chemi-cal industry. In the context of „WasteLogistics“ our engineers develop tailor-madedisposal concepts and integrate these intoour products.

Our customers can profit from our experiencesin almost all lines of business, industry andtrade.

This way extensive engineering advice leadsto individual system solutions.

The Welger Waste Rollers, RV 641, RV 642and the newly developed, fully automaticRC 660, due to their mobile and compactdesign are especially suitable for thecompression and economic disposal ofpackaging and other recycling materialsgenerated in the retail trade and manu-facturing industry.

Advantages at a glance:

• Compact design,and mobile

• Robust and reliablefor constant daily usewith easy operation

• Automatic wrappingtechnique

• Improved hygienicconditions at work,extremely safein daily operation

• Impressive cost saving operation by a lowdeployment of labour and by reduced effortof storage, transportationand disposal

Economical disposal presupposes collectingof segregated recycling materials. This canbe carried out simply and effectively, directlyat the point where the waste material is ge-nerated. At these points, our small, compactand mobile Waste Rollers can work very wellsaving space and time.

The Welger Waste Rollers RV 641 and RV 642,compress voluminous waste material, byrolling it into cylindrical bales in the easiestway and in the narrowest place.

RV 641• RV 642

Due to their compact and mobile design,both Waste Rollers can be integrated intooperational processes almost at every pla-ce where recycling materials occur to com-pact big-bags, films, cardboard packages,plastic strapping bands, paper stripes,foam packaging and matting material,fleece materials and many other specialmaterials for disposal.

Explainationof the working method:

After being segregated, the recycling ma-terial can be put manually on the feed ta-ble of the machine. Once collected by theconveying belt, it is led into the compac-ting chamber and formed into a cylindricalbale by the rotating action of two belts.

With a continuous material supply, the twoconveying belts form a cylindrical bale inwhich the pressing material is compacted.

The operation can be interrupted as nee-ded in the baling process. During everyinterruption the material remains com-pact and under permanent pressure. The-refore the waste cannot re-expand in themachine.

The filling level is shown continuously viaa LED display. After achieving the pre-selected bale size (on the model RV 642three bale diameters can be selected) thewrapping is started manually by puttingthe binding material into the feed intake.Depending on the quality of the waste ma-terial the bales are wrapped either twicewith twine or just once with wrapping film,automatically. (RV 642 only works withfilm wrapping).

After the twine-tie or wrapping process iscompleted, a cutting device cuts the bin-ding material. The baling chamber canthen be opened electrically by using aswitch on the operating console and willbe closed again after having ejected thebale automatically. On the RV 642 an in-itiator counts the film-wrap for the bale.After completion, cutting the film and ejec-tion of the wrapped bale is carried outfully automatically.

Special equipment:

Fitted with a special extractor system theWelger Waste Roller RV 641 can be usedin many areas of the chemical industry.Materials that are contaminated with resi-dual and dangerous dusts travel thoughthe extraction area at the feed table. Thuscontamination of the waste material is re-duced to a minimum.

Welger Waste Rollers RV 641 andRV 642 are equipped with the world-wide-approved Welger-Waste Rol-ler design, with material compressi-on formed by two wide, circulatingconveying belts with a special grip-ping structure profile. These beltsform a round bale chamber in whichthe compression of the introducedmaterial is carried out. Twine or filmwrapping and automatic ejectingwill be carried out after achievingthe pre-selected bale diameter.

RC 660Compact in size and fully automatic operation.The new development of Welger is a consis-tent step for the rationalization and full auto-mation of the internal disposal of recyclingmaterials.

The Welger Waste Roller RC 660 works withmany different, cleanly sorted packaging ma-terials. Especially re-expanding waste, whichcan be reduced down to 10% of its originalvolume.

Advantages at a glance:

• Extremely compact style,and mobile

• Robust and reliablefor daily use witheasy operation

• Impressive cost saving operation by a lowdeployment of labour and by reduced effortof storage, transportationand disposal

• Fully automatic operation• Improved hygienic

conditions on site

The Welger RC 660 is a newly developedbaling press, compressing voluminous ma-terials like big-bags, plastic films, card-board packaging, plastic strappingbands, paper and paper stripes, foam ma-terial, fleece substances and many otherspecial materials to cylindrical bales.

The waste material is automatically suppliedvia conveyor belt or air technology. It iscollected in a filling hopper, where a lightbarrier is integrated. The baler starts auto-matically after being triggered through thelight barrier. The pressing material is thenrotated into the bale chamber inbetweenthe two conveyor belts. After the baler hasprocessed the waste material the light barri-er recognises the empty hopper and swit-ches the RC 660 to the „Stand-By“ mode.

With more waste material supplied, thetwo conveying belts form a round baleof the compressed waste. The feedingcan be interrupted as necessary andcontinued again at any time. Even stron-gly re-expanding materials remain com-pressed.

The filling level is shown on operator’spanel continuously via a LC display. If thepre-selected bale diameter is achieved,the wrapping process is started automati-cally, by inserting the wrapping film intothe bale chamber. By continuously rota-ting the bale in the chamber it is wrap-ped with the wrapping film automatically.

An initiator counts the wraps on the baleand then releases the cutting device auto-matically. After this, the bale-ejectiondoor is opened automatically and the fi-nished bale is ejected. The door thenshuts itself automatically.

The RC 660 works exclusively with wrap-ping film. The consumption of film isshown at the display and the roll of filmcan be replaced in a few easy steps.

The Welger Waste RollerRC 660 has the worldwideapproved and optimisedWelger design of rollingcompression, with two wide,circulating conveying beltswith a special grippingstructure profile. These beltsform a round bale chamberin which the compression ofthe introduced material iscarried out. Because of theconstruction of the baler thecompressed material cannotre-expand, either in the balechamber or during interrupti-on of the baling process.
