In a nip roller apparatus, a drive roller and an idler roller are arranged for conveying an object. The rollers include shafts having toothed wheels mounted thereon for transmitting rotation of the drive roller to the idler roller. A pressing device is provided for biasing the idler roller against the drive roller. The idler roller is mounted in a bearing support which includes guide slots for permitting sliding movement of the idler roller relative to the drive roller. The guide slots are positioned at an angle relative to a line which extends through the centers of the shafts and includes a point of contact between the toothed drive wheel and the toothed idler wheel.
