A transfer device, adapted to convey an object in a conveying direction, and selectively transfer an object in a second direction angled to the conveying direction; the transfer device having a plurality of belt carriers, circumferentially running along the transfer device, a traction belt circumferentially running along the transfer device, along which the plurality of belt carriers is arranged; circumferentially running transfer belts forming an upper run and a lower run; wherein each belt carrier carries a transfer belt, which protrudes above the belt carrier, and wherein the plurality of transfer belts is defining a conveying plane, on which the object comes to rest during conveying; wherein for laterally transferring the object the transfer belts are selectively driven. The transfer device also has a tensioner, which is adapted to change the tension of the traction belt.

Crossbelt sorter (1), adapted to sort an object (9) into one of a plurality of discharge stations (14); the crossbelt sorter (1) comprising a plurality of crossbelt carts (11); the crossbelt carts (11) are movable along a conveying direction (R) on a circumferentially closed conveying track (13); the crossbelt cart (11) comprising a crossbelt (12); wherein the crossbelt (12) provides a conveying surface for supporting an object (9) to be conveyed; the crossbelt (12) is moveable relative to the crossbelt cart (11) in a traverse direction (Q) traverse to the conveying direction (R); the crossbelt sorter (1) is adapted to transfer said object (9) from the conveying cart (11) selectively into one of the plurality discharge stations (14) by selectively driving said crossbelt (12) in the traverse direction (Q); wherein for driving said crossbelt (12) said crossbelt cart (11) has a drive wheel (41) which is adapted to engage with a friction bar (31); said friction bar (31) is located stationary along the track (13) and transferable between a driving position and a disengaged position, characterized in that the crossbelt sorter (1) is adapted to vary an actuation position (Y0, Y1, Y2) within the range of said friction bar (31).
