Technical installations complex Gura Râului Sibiu
In the 18th and 19th centuries, the breweries in Gura Râului, Sadu, Oral, Tălmăcel and other villages in Sibiu developed and improved a lot using the raw material procured from transhumance pastoralism. The large-scale development of the trade in fabrics and other textiles led to an increase in the number of installations for processing wool, which were lined up like a real "salba" in several villages in the area. You can also feel the influence of the German population, which contributed a lot to the development of the textile industry.
The Gura Râului installation complex located in the National Museum of the Village includes whirlwinds, a basket for thickening tendrils, a basket for pulling hair and a piua, each in a separate construction.
The truncated-conical vortex in which the water falls, spins, whitens and thickens the wool skeins.
The basket to be thickened is a cylinder made of a braid of reeds, fixed on the axis of the hydraulic wheel. The moistened candles, inserted inside, are spun by the movement of the wheel and, thanks to the warm steam, they thicken, becoming fluffier.
The basket for pulling hair, built between the years 1876-1900, is also cylindrical in shape made up of movable bars on which the fabrics are placed. This cylinder rotates being driven by the wheel, through its spindle. In the rotation movement, the fabrics pass in front of a board with rows of nails, which pull threads from them and fluff them, making them fluffy.
The piua dates from the second half of the 19th century, it is equipped with eight hammers whose lower ends have scaled "sponges" (notches) and fall alternately hitting the waves of fabric placed in the cavities deeply dug in the oak trunk. The wheel equipped with a spindle with wooden risers, actuated in the rotational movement by the fall of water, engages the tails of the mays or hammers and raises them up. Coming out of the gear, the hammers fall alternately on the pieces of cloth, which rotate automatically in the hollows carved into the wooden trunk, where they are wetted with cold and warm water. The operation lasts from 8 hours to 14 consecutive hours, the respective fabric thickens and becomes postav (dimme), from which winter clothes are made.
