Dacapo DB200 Strip wind Builder

 

                               

 

The Dacapo DB200 is a modern reliable strip wind builder, built on the base of an Orbitread® 200.

The bed frame, front end and other mechanical parts are kept from the original builder. The builder is upgraded with:

ü  New electric cabinet with PLC control and soft starter for the extruder

ü  New PC based operator workstation

ü  New spin motor and gear box

ü  New winding radius adjustment motor and screw

ü  New Azimuth motor and gear box

ü  New or refurbished extruder gear box and thrust bearing block

ü  New extruder screw

ü  New or refurbished extruder barrel

ü  New pneumatic system

ü  New 2 zone temperature control system

 

Altogether, this will give a modern, reliable strip wind builder, easy to operate and maintain.

 

 

The PC is the operator’s interface to the builder. The PC is used to create building programs, to select which building program to use and to store statistical and measurement data.

§  A building program is created using a graphical picture of the tyre. The tyre profile is divided into 1 to 25 zones.  Building program data for each zone is entered to a table. A practically unlimited number of building programs can be stored.

§  The operator Changes to a new tyre size by selecting the adherent building program from a list. Extruder temperatures, tread profile etc are automatically set for the new building program without any other intervention from the operator. To change the building program takes less than 5 seconds unless the extruder temperature changes too.

§  After finishing the building of a tyre, the PC stores all process data in a database. This data can be retrieved by tyre, by building program or by batch.

 

Several builders could be networked together or to a server. A common database for building programs and process data can then be used.
