An unscrambler apparatus, comprising: - one or more handling devices (R1, R2, R3), - a product picking area configured to receive a flow of scrambled products to be handled by the one or more handling devices (R1, R2, R3) arranged at said product picking area, - a transfer conveyor configured to receive scrambled products picked from the product picking area and released at the transfer conveyor by the one or more handling devices (R1, R2, R3), - a product unscrambling device including a product input and a product output, characterized in that, the product unscrambling device is configured to receive scrambled products from the transfer conveyor along a feed direction at the product input and comprising a plurality of carriers configured to take over, carry through the product unscrambling device, and release the products coming from the transfer conveyor, wherein each of the carriers can be selectively routed to a first path (P1; P1*), a second path (P2; P2*), and a third path (P3; P3*), wherein: - the first path (P1; P1*) extends from the product input to the product output, whereby a carrier routed to the first path (P1; P1*) is configured to carry a product having a first, desired, orientation through the product unscrambling device and release the same at the product output thereof, - the second path (P2; P2*) extends as a transition from a first direction (h1, *h1) of the products at the product input to a second direction (h2, *h2) incident to the first direction (h1, *h1), wherein the second path (P2; P2*) includes an interchange station to the third path (P3; P3*) at the second direction, and wherein a carrier routed to the second path (P2; P2*) carries a product having a second, undesired, orientation, - the third path (P3; P3*) extends as a transition from the second direction (h2, *h2) to a third direction (h3, *h3) at the product output, whereby a carrier routed to the second path (P2; P2*) and carrying a product having a second, undesired, orientation is configured to be routed to the third path (P3; P3*) at the interchange station so to present the product at the product output with the first, desired, orientation. - one or more handling devices (R1, R2, R3), - a product picking area configured to receive a flow of scrambled products to be handled by the one or more handling devices (R1, R2, R3) arranged at said product picking area, - a transfer conveyor configured to receive scrambled products picked from the product picking area and released at the transfer conveyor by the one or more handling devices (R1, R2, R3), - a product unscrambling device including a product input and a product output, the product unscrambling device is configured to receive scrambled products from the transfer conveyor along a feed direction at the product input and comprising a plurality of carriers configured to take over, carry through the product unscrambling device, and release the products coming from the transfer conveyor, wherein each of the carriers can be selectively routed to a first path (P1;

P2*) extends as a transition from a first direction (h1, *h1) of the products at the product input to a second direction (h2, *h2) incident to the first direction (h1, *h1), wherein the second path (P2; P2*) includes an interchange station to the third path (P3; P3*) at the second direction, and wherein a carrier routed to the second path (P2; P2*) carries a product having a second, undesired, orientation, - the third path (P3; P3*) extends as a transition from the second direction (h2, *h2) to a third direction (h3, *h3) at the product output, whereby a carrier routed to the second path (P2; P2*) and carrying a product having a second, undesired, orientation is configured to be routed to the third path (P3; P3*) at the interchange station so to present the product at the product output with the first, desired, orientation. - the first path (P1; P1*) extends from the product input to the product output, whereby a carrier routed to the first path (P1; P1*) is configured to carry a product having a first, desired, orientation through the product unscrambling device and release the same at the product output thereof, - the second path (P2; P2*) extends as a transition from a first direction (h1, *h1) of the products at the product input to a second direction (h2, *h2) incident to the first direction (h1, *h1), wherein the second path (P2; P2*) includes an interchange station to the third path (P3; P3*) at the second direction, and wherein a carrier routed to the second path (P2; P2*) carries a product having a second, undesired, orientation, - the third path (P3; P3*) extends as a transition from the second direction (h2, *h2) to a third direction (h3, *h3) at the product output, whereby a carrier routed to the second path (P2; P2*) and carrying a product having a second, undesired, orientation is configured to be routed to the third path (P3; P3*) at the interchange station so to present the product at the product output with the first, desired, orientation.
