FIELD: leather processing industry. SUBSTANCE: device has two pressing rolls, suspension- mounted transporting rolls, and drive unit. Transporting rolls are made up of identical groups. Each group includes two upper rolls and lower transporting roll installed between them for possible contact with both. Axes of upper transporting rolls lay in common horizontal plane, and rolls themselves are positioned at different sides relative to lower transporting roll. Each pair of upper transporting rolls can oscillate relative to lower transporting roll due to oscillation drive unit. Such drive unit of upper transporting rolls has pair of L-shaped brackets with pin on their one ends carrying driving gear with sprocket. Other ends of L-shaped brackets of both pairs of upper transporting rolls are mounted for possible oscillation on distribution shaft. EFFECT: high efficiency. 1 cl, 2 dwg
