Items supplied for TVD panel production line:
• In its minimal configuration with a capacity of ca. 250.000,00m2 of
finished TVD panels.
– Item A:
• (a) wire uncoiling reels for drawn wire consisting of:
– wire rod holding fingers to hold wire bar coils for vertical pay-off;
– one machine for bar straightening and cutting at required length;
– one machine for bar bending.
•
(b) adjustment of reinforcement meshes;
– one machine for mesh cutting;
– Item B:
• (a) one machine for steel connection elements
– consisting of an hydraulic press and forming tiles;
• (b) one machine for Polyethylene connection elements
– consisting of the PE production machine and forming tiles.

– Item C:
• (a) one machine for Polystyrene block cutting
– consisting of a fixed support, mobile carriage, insulated support, current
generator and monitoring electric board.
• (b) two machines for Polystyrene punching
– Punching of the polystyrene foam blocks at the size of panel so that they are
placed in vertical position and hydraulically pressed against preheated
thermo-spears placed in the positions required for the fixing of the connection
elements. Thermo-spears can have variable positions in order to suit the
particular structural need.
– Item D:
• (a) three machines for assembling of panels
– Panel assembling is done in a vertical position so that reinforcement meshes
and thermo elements are placed in their final position. Connection elements
are then fixed manually in the particular position.

– Item E:
• (a) one machine for packing finished panels
– Stacked finished panels (6 panels in a stack) are placed on the machine and
tied together with stripes for easier manipulation and transportation
– Item F:
• (a) two fork-lift trucks (10 kN)
– Item G:
• (a) one set of tools for electrical and mechanical maintenance

– Optional items:
– Item H:
• Complete automation of production and storage lines
– To connect production to storage lines with steel frames and guiding rails to
enable easier, faster and semi-automatic transport of the elements.
– Item I:
• Polystyrene foam unit
– To transform polystyrene granulates into foam blocks.
– Item J:
• Electrowelded mesh unit
– To produce electrowelded reinforcement meshes.
– Production building
• For the production line in its minimal configuration (with the possibility of later
additions), the building should be around 1650m2, i.e. 27m large x 60m long and
6m high; a storage surface place of ca. 650m2 would also be recommended to
stock the panels.
