Abstract

A feeding device (12) for a paper strip or a continuous paper form (13) comprising a transport assembly (31), including two motor rollers (32, 33) of identical diameter synchronous in the rotations and two pinch rollers (36) and in which the motor rollers (32, 33) are provided for engagement with two lateral nipping areas of the form (13) and the pinch rollers (36) are engageable with the nipping areas against the motor rollers (32, 33) for the transmission of dragging forces to the sides of the paper form (13). The feeding device (12) further comprises a stiffening assembly (19) for transversally engaging the paper form (13), upstream of the motor rollers (32, 33) and the pinch rollers (36), and in which the stiffening assembly includes bending and contrast elements (44, 46, 48) to deflect the paper form longitudinally from its direction of movement.
