The invention relates to a device and a method for collecting successively fed flat objects, in particular sheets. The device contains a blocker having at least one movable blocking element for stopping and subsequently releasing a certain number of objects fed, wherein the blocking element is a rotational body rotatable by a motor around its middle axis which, at its exterior periphery, has at least one reception for stopping the front edges of the objects fed in an idle position of the rotational body and for its deflection when turning the rotational body, and wherein at least one transport element for advancing the objects deflected when turning the rotational body is associated to the rotational body.
