Sincro TriBloc, a compact system blows, labels, fills and caps PET bottles provides significant savings, not only in space, but also in investment and running costs, and in energy.
The innovative design of the Sincro TriBloc does away with several costly elements found in traditional lines. There is no need for a bottle rinser, since the bottle blow moulding and filling stations are connected directly together. Nor are there any belt conveyors between the filling and labelling stations, since the bottles are labelled immediately after they are blown, filled and capped.

55% reduction of space
The entire system works in less space, consuming less energy, with fewer operators and lower maintenance than other systems.
Space requirement is down by a massive 55% compared with a standard line, operating costs are around 15% less, and total investment costs are cut through the elimination of intermediate buffer stations. Operation is centralized and logistics are smoother.
The Sincro TriBloc also produces better bottles. In particular, the quality of the labelling is consistently high because no condensation is allowed to accumulate on the bottle surfaces before they are labelled.
SIPA offers a range of Sincro TriBloc systems, encompassing models with outputs starting at 12,000 bottles per hour, rising to 48,000 bottles per hour.

Class-leading pieces of individual equipment
The system incorporates class-leading pieces of individual equipment. The SFR EVO preform blow moulding unit, for example, features a high performance oven with innovative ventilation for high process consistency, low working temperatures and fast start-up from cold. Incorporation of “crocodile” opening allows moulds to be fitted more closely together, and very low centrifugal forces on the preform and bottle wheels favour lightweight containers.
The bottle labelling station incorporates “Adhesleeve” technology from fellow Italian company P.E. Labellers SPA, considered to be a revolution in roll-fed labelling. This uses “pre-glued” roll-fed film, white or transparent, thinner than the standard films processed on conventional roll-fed labellers. The “Adhesleeve technology obviates two major problems that contributed to the ineffectiveness of Roll-Fed labellers: hot melt glue and label cut. It is a convenient and environmental-friendly solution as labels and (water-based) glue are 100% recyclable, along with the bottle and the cap, and problems with glue spray deposits and fumes are eliminated.

Adhesleeve technology: roll-fed labelling revolution.
Label cutting is also more efficient. This is because cutting and application operations are carried out on a single cylinder. On traditional roll-fed machines, the label is cut by the interaction of a rotary cutting blade and one or two fixed ones. The difficulties in the adjustment of the blades during their replacement, which can take between four and six hours, are well-known, as are the production stops due to imperfect label cutting.
With the Adhesleeve system, those difficulties are eliminated. There is no need to adjust the cutting unit for different film thicknesses, cutting devices can be replaced inside ten minutes at most - without the need for special tools - and the application cylinder does not require cleaning or maintenance. Total line utilization factor increases by between five and ten percent as a result.
Furthermore, Adhesleeve technology is highly energy-efficient. No energy is expended on such elements as glue heating, a glue recirculating pump, a vacuum pump motor for the cutting drum or a fume suction hood. Adjustments and maintenance during operation are much reduced too. Depending on the type of label used (transparent, single white layer, full cover), Adhesleeve labels can actually cost less than standard labels. Extreme operating flexibility.
Sincro TriBloc can be equipped with gravimetric, volumetric and isobaric fillling systems, capable of handling still and carbonated soft drinks, juices and hot filled products. These include Stillfill, Isofill, Isotronic and Unitronic units. SIPA’s Sincro TriBloc capping machine is extremely versatile, capable of handling a wide range of flat and sport caps, with quick and easy changeovers. This is fitted as standard with the latest Cap Stream gravitational feeding system that guarantees the highest efficiency and a complete emptying of the machines in the Sincro TriBloc system in the unlikely case of a cap jam. This is a very clean feeding system, working without compressed air.
Alternative feed systems can be supplied if required. All can be equipped with SIPA’s “Cap-vision” monitoring and control system. This is capable of detecting and inspecting deformed caps, up-side down caps, security rings (and whether or not they are intact) and gaskets, as well as colour.
Transport between the different stations in the Sincro TribBloc is carried out by star-wheels. These are very well suited to lightweight containers and are designed to avoid bottle jams. On request, special devices can be incorporated to reduce change-over times between different container shapes and neck sizes.
Every single unit in the Sincro TriBloc system can be decoupled from the bloc so that bottles and/or preforms can be evacuated if there is a micro-stop in the system, whether it be in the blowing station, the labelling station or the filling and capping station.
SIPA can in addition configure systems with laminar flow cabins with HEPA (High Efficiency Particulate Air) filters providing clean room quality up to ISO 5.
