The machine comprises a frame, a first roller rotatably supported by the frame and a second roller rotatably supported by the frame and disposed below the first roller to cooperate therewith. A gear is secured to the first roller to be rotatable therewith meshes with at least two pinions, each mounted on the shaft of a respective pressure-fluid operable motor. A pump is connected to each of the pressure-fluid operable motors to supply pressure-fluid in common to the motors so that all the pressure-fluid operable motors operate in synchronism.
