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.

TVD panel production line-5

– 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

– hand drill with D=13mm

– set of screw keys and tools for mechanical maintenance

– set of accessories and instruments for electrical maintenance

– arch welder for electrodes

– column drill with D=16mm

– column grinding wheel

– working bench and two shelves

TVD panel production line-6

– 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.
