ABSTRACT:
A roller press for surface impregnating leather and similar materials, includes a load-bearing structure (2) which supports an upper impregnating roller (8), a lower drive roller (9), and a pair of conveyor belts (5 and 6) placed one above the other which turn in the same direction and partly touch each other so as to forward feed the leather (P) to be impregnated. The rollers are approximately parallel to each other and spaced apart so as to create a converging/diverging channel (10) between them, having the minimum section (11) approximately equal in height to the thickness of the leather being worked. There is a pressing member (20) arranged immediately upstream of the minimum section (11) which acts flexibly and uniformly over the entire width of the leather so as to keep it in stable contact with the lower drive roller (9) and preventing it from rolling up.
