LUCCA, Italy, July 20, 2010 (Press Release) -At the end of June Wepa Lucca completed the rebuild of the TM#1 in Pian della Rocca (Lucca Italy).

The rebuild has been carried out by Toscotec according to the tight time schedule of only ten days shut down from paper to paper.

The Pian della Rocca plant was composed of a Toscotec sloped wire machine with grooved cast iron YD 12 ft diameter, originally supplied in 1987 and rebuilt into Crescent Former in 2000 by Toscotec.

The machine featured a paper trim at the reel of 2750 mm with a max running speed before the rebuild of 1700 mpm (max production output of 80 tpd) with a speed limitation on production of low basis weight.

Scope of the project was to increase the machine speed up to 1900 mpm and improve paper quality as well as the runnability.

Toscotec scope of supply included: headbox revision and upgrade, felt run modification with new felt rolls, new steel yankee dryer 3660 mm diameter TT SYD 12FT, new creeping doctor on the YD, new TM mechanical drives, new steam & condensate system, new lubrication unit, new blind drilled press roll with a bigger diameter than the existing one.

The project was handled on a turn key basis by Toscotec being the engineering, erection, commissioning & start up included into the scope of supply.

During the shut down some additional interventions were also carried out by the mill: new building roof, DCS upgrade, boiler plant maintenance, new bridge crane, new air conditioning system for electrical room, preliminary works for the future stock preparation upgrade.

Totally 22 companies with 96 persons were involved in the rebuild installation phase harmonized in a perfect way between Toscotec and Wepa Lucca.

Only one week after the start up the machine has produced more than 100 tdp of high quality tissue and the TT SYD 12FT has demonstrated its superior performance in terms of production and energy saving.
