Beverage Can Line

The Stolle Coolant Filtration System can process up to 660 gallons of coolant per minute to accommodate up to 20 bodymaker machines. It features two carbon steel pressure vessels with advanced design, high flow filter cartridges that feature a cleaning cycle of about 30 minutes from depressurization to restart. The system is designed as a modular package incorporating coolant reservoirs, filters, pumps and controls, all mounted on a smaller footprint base for economical transport and easier installation.

The Stolle Trimmer features an updated design that trims DWI cans and bottle preforms in sizes up to 10” high with stationary can pads and trimming heads that move the knives to the cans.  Keeping the can bottoms in the alignment to the bodymaker domer allows simpler and more reliable crossover trackwork, and the sliding base design allows the 3 trimming heads to be easily repositioned for different can heights with no change parts needed.

The Optimus Can Washer is the most water and energy-efficient washer available.  Many features including an optional heat recovery system and rinse water recycling make the Optimus more sustainable and environmentally-friendly than ever (see video under “Media”).  The multi-stage machine has wash, rinse and treatment sections, and can be configured to meet any can washing requirements.  The Optimus is solidly constructed of premium materials for long service and easy maintenance.

Designed to mate on the discharge end of an Optimus or other make of can washer, the Optimus Can Dryer completely and efficiently dries cans with heated forced air.  It features a suction-type impingement recirculating air system which allows for a high heat transfer rate, while maintaining can stability via vacuum throughout the heating zone. The results are a compact drying package with reduced dwell times, reduced operating temperatures and smaller overall footprint.

For beverage label branding that requires basecoated cans, Stolle Concord and Rutherford Basecoaters apply a solid opaque coating to can bodies in preparation for decorating at speeds up to 1800 CPM.  Both machines have dual coating units with independent speed controls that produce highly accurate coating weights and a superior can finish with minimal overlap and slinging.

The Stolle DecoCure Pin Oven cures the external coatings on 2-piece beverage cans immediately after they exit a basecoater or decorator machine. This specially-designed oven is designed to thermoset the coatings in less than 10 seconds with superior temperature uniformity and can stability throughout.  High efficiency recirculation fans provide air delivery through U-shaped nozzles which follow the serpentine chain path throughout the heating zone, which ensures an optimum heat transfer rate and a low temperature differential between the upper/lower sidewalls.

Stolle inside spray systems apply a coating to the inside surface of two-piece can bodies at high speed and with maximum production efficiency.  Stolle offers 2 models that feature Reynolds inside spray technology: the DG-250 (dual gun) has two spray guns to coat the inside of the can, while the TG-350 has a third gun to spray the can dome.  Designed primarily for steel cans, the TG-350 passes cans to a vacuum turret wheel that holds the can in place for the dome spray, limiting potential can damage and overspray.

The Stolle InterCure Oven cures the internal water-based coating of 2-piece beverage cans after they are discharged by the Inside Spray Machines.  The oven also finishes curing the ink and varnish on the exterior of the cans resulting in fully cured cans that are ready for the final steps of production.  The InterCure Oven features a 3-zone configuration (plus an optional cooling zone) that allows for full flexibility in the curing process, next generation gas burners that reduce energy consumption, and has superior temperature uniformity of +/- 2° C.

These specialized machines are designed to add tactile patterns to the sidewall of DWI beverage cans for enhanced brand awareness.

The Stolle Registered Embossing Machine embosses patterns in the can sidewall that register with the printed decoration. The Stolle Profiler Machine embosses vertical flutes in the can sidewall.  These tactile patterns improve the product’s brand name recognition and create a competitive advantage over traditional aluminum or steel cans.

The new Stolle E-NCKR machine represents another milestone in Stolle’s complete line of value-added can production equipment.

This modular machine is designed to neck 2-piece cans to accept a specified diameter end. In addition to necking, the machine can be equipped with modules to perform other processing functions on the cans, including flanging, base reforming and light testing. The Stolle E-NCKR can also be equipped with infeed and discharge vision inspection systems to perform 100% inspections of cans within the machine.

Stolle designs, manufactures and commissions conveying systems for each step in the can line.

These conveyors include cup discharge air tables, recirculation cup systems, bodymaker infeed sweeps, trimmer discharge tracks and wet can conveyors, washer infeeds, washer discharge turnover units, bright can bi-directional accumulation conveyors, decorator infeeds, spray infeeds, spray discharge and IBO infeeds, necker infeeds and discharges, vacuum transfer units and mechanical conveying for finished cans.  All Stolle Conveying Systems products are custom-engineered and are built with the highest quality materials for long life and reliable operation in a can line environment. Stolle also provides conveying systems for 3-piece cans, PET containers, magnetic conveyors and elevators, as well as conveyors for specialized food processing applications.
