Patent ID: 7934721

Claim:
Equipment for transferring sheets with change of direction for sheets entering along a first direction, comprising: output rollers for moving entered sheets along a second direction right-angled with respect to the first direction; a pair of opposite wheels or more pairs of opposite wheels actuatable in the rotation for engaging and moving, along the second direction, the sheets entering along the first direction; and an actuating motor for cyclically actuating the pair of opposite wheels or the pairs of opposite wheels; wherein at least one wheel of the pair of opposite wheels or of each pair of opposite wheels has an engagement sector or more engagement sectors for engaging the other wheel and a depressed sector or more depressed sectors; and wherein the depressed sector or each depressed sector is faced to the other wheel of the pair in a reference position to define a condition of receipt for the entering sheets, while the engagement sector or each engagement sector is designed for engaging and moving the entering sheets in a condition of engagement and movement; the actuating motor being provided for actuating said at least one wheel from the reference position to positions of engagement and movement for engaging and moving the entered sheets up to the engagement with the output rollers and return to the reference position, and each sheet entered along the first direction being moved by the engagement sector or by the engagement sectors, while a following sheet being allowed to enter and to be moved along a first direction up to the space defined by the depressed sectors for a new transferring of the sheets, jointly with the movement along the second direction of a sheet engaged by the output rollers, wherein the pair of opposite wheels or each pair of opposite wheels are in condition of synchronism and comprise each one a substantially frusto-conical tapered surface for the sheet in receipt, and wherein the other wheel of the pair of opposite wheels or each other wheel of the pairs of opposite wheels, comprises a coating configured to provide high adherence.
