Narrative:

During takeoff; first officer (first officer) experienced binding aileron control immediately after takeoff as he introduced left aileron input to compensate for a crosswind takeoff. The binding limited left wing down input. Binding released several seconds later but first officer experienced a subsequent but less forceful binding during right movement of the aileron. Again the binding released and no further binding was felt. After discussion and reference to the QRH; we notified ATC and aircraft returned to [the] airport for an uneventful overweight landing. After returning to the gate; aileron binding was again evident. Maintenance was briefed and maintenance logbook entries were made for both the binding aileron and overweight landing.
