ABSTRACT:
A transporting, sieving or filtering base or bottom consists preferably of extensible or bendably elastic materials and is divided into zones and supported. The individual zones are fixed between transverse elements or carriers which either belong to a driving frame system or constitute transverse braces of a frame or other supporting elements. The invention is particularly characterized in that the carriers or transverse braces limiting the zones have supporting or moving elements which make them movable individually upon a corresponding sliding roller and an elastically movable guiding path or in an elastically movable guiding profile. The movement is so carried out that the carriers or braces are shiftably coupled with each other while moving in the same direction in or upon these elements when the cross-sections connecting them reach their greatest possible longitudinal extension. Due to this the parts of the transporting, sieving or elastic bases located between the transverse braces or carriers or sections located close to the transverse braces which transmit to them a concave or convex initial location or a pretensioned horizontal initial location, are placed into a continuously moving preferably linearly extending possibly overextended position.
