The utility model provides a compression roller and pole piece crease -resistance device. The compression roller includes dabber and a plurality of roll body subassembly. The dabber has: the perisporium, it has the branch air inlet to distribute, and two end walls to form inside cavity together with the perisporium, and in two end walls or the perisporium at least one be provided with with total air inlet of outside compressed gas source intercommunication. A plurality of roll body subassemblies support in proper order along the axial of dabber and lean on the ground cover to establish on the perisporium of dabber. Each roll body subassembly has: on the perisporium of dabber is located to interior roller shell, fixed cover, and the outer peripheral face inclines to the other end along axial one end, outer roller shell, on the roller shell, the inner peripheral surface sloped to the other end along axial one end in the cover was located, spring coil, cover are located on the outer peripheral face of interior roller shell, fixing retainer ring, the retaining ring of ventilating, the boring to with the branch air inlet intercommunication that corresponds, and the endwise slip piece, axial sliding motion can follow to make the head end expose in ventilating retaining ring and contacting with outer roller shell. Pole piece crease -resistance device includes the compression roller.
