The telescope unit of the linear system as well as the rotating table of the roundtable system may be equipped with the components of four different manufacturing modes:
     � pressing      � injecting      � spinning      � casting
All manufacturing modes are thus available at any given time � allowing to switch production according to the design of the glass item. The four-in-one linear combi-system as well as the four-in-one roundtable combi-system stand out as extremely flexible production systems with regard to the range of designs available as well as the machine speed.

Flexibility has become far more than an extra-benefit: it has become a must, because only flexible production systems allow to respond quickly to a wide range of design demands on the market and to supply to the market promptly. Combining four different manufacturing modes into one machine � linear system or roundtable system � expands the range of designs available while short jobchanges guarantee high productivity. Flexibility that does not affect productivity is flexibility that is a real comparative advantage.

It is crucial for the production system to provide a sound relation between the means applied and the target to be achieved. This is why flexibility does not only cover design variety but also optimised capacities and tool costs. The linear system as well as the roundtable system focus on different targets production rates:
� The linear system is designed to produce comparatively small numbers of glass items of one design. The fact that only one glass item goes through the production steps in linear sequences reduces tool costs to a minimum, since only one mould for one production cycle is required.
� The output of the roundtable system lies significantly above that of the linear system, because 2 to 20 glass items run simultaneously through the different production steps, depending on the number of stations the roundtable system accommodates � and on the number of stations equipped for each manufacturing mode.
Since up to three linear system may be fed by one feeder system and since the number of stations fully equipped on the roundtable varies from two to twenty, there are many ways to establish a targetoriented production.

Optimal adjustment to individual production conditions, design requirements and production targets is not equivalent to expensive engineering. The basic equipment as well as the pressing, injecting, spinning and casting components are firmly established while their combination is highly innovative. The four-in-one combi-system is the most cost-saving combination of proven components providing optimal adaptation to individual requirements. Flexibility is the pre-requisite for economically reasonable production systems � and it is a solid basis for a market-oriented production.
