In a device for dispensing sheet material having at least one storage container for a stack of said sheet material, a withdrawal device associated with said storage container consisting of withdrawal rollers for removing sheets of said sheet material from said storage container, a plurality of spaced transporting rollers for conveying removed sheets along a path, spaced contra-rotating rollers which can be adjusted between said transporting rollers to obtain optimum detention of duplicate sheets thereby preventing the simultaneous passage of a plurality of sheets along said path and a dispensing station arranged at the end of the conveying path, the improvement comprising said contra-rotating rollers being formed of an inherently stable material, at least some of the transporting rollers being formed of an elastically yielding material preferably having a cellular or porous surface for good adhesion to said sheets, and at least some of the transporting rollers being formed of an inherently stable unyielding material to prevent a stack of said sheets from compressing said elastically yielding material and passing between said contra-rotating rollers and said elastic transporting rollers.
